Today I got my Wash Pro Stainless Steel Washer & Dryer from Utah Biodiesel Supply and I installed it on one of my wash tanks, where I had been bubble washing my latest batch for about a week. The washwater was still a bit soapy, but it looked like it was pretty well done. I drained it and used the Wash Pro to add fresh was water. Then I hooked up the wash tank to the pump and recirculated the wash water spraying it on the biodiesel. The pump is pretty strong and after about 15 Minutes all the water was totally blended with the biodiesel. There was no separation at all. I let it settle for an hour and did it again. After the second go-around the water was completely white with soap! That is totally amazing. This little bit of stainless steel is going to make a big difference in the quality of my fuel – at least as far as the soap is concerned.

Just how bad the effects of the soap actually are is not totally clear to me. Daniel Sheedy of Environment Australia, argues it’s no big deal at all (see section 6.16). I don’t think it can be good for the performance of the fuel.

My latest batch of biodiesel is looking pretty good. I washed it all week. I even built another washtank (left). Maybe tomorrow I’ll start drying part of the batch. There is no hurry – I still have about 30 gallons in stock.

Yesterday, after I built the new washtank, I filled it up with 25 gallons of biodiesel and another 15-or-so gallons of water, when I noticed that the damn tank was leaking all over the floor. Quickly I rigged up the pump, hooked it up to the tank and began pumping everything into the other tank. But the pump whipped the soapy water into an emulsion and could not move it! So I had to empty the contents into buckets and dump he buckets into the other tank! UGH!

When I fixed the leak today, I tightened the PVC adapter too much and broke it. I saw I still had a black iron 2” nipple, so I used that. Turns out that the iron nipple with the PVC ball valve works much better than the all-PVC business (right tank). It’s much sturdier.

How many types of computer networks do you know? There is the most common TCP/IP networking, across copper, fiber or wireless (very likely that is what you are using to read this page). IPv6 is the new kid on the block, and some may remember the old stuff, like Tokenring and IPX, and when all else fails, good, old sneakernet is never down! Now there is also DieselNET. On DieselNET, data take the bus – no not the SCSI bus! The BUS, as in public transportation! No joke! In this implementation of a packet-switched network protocol, the data are ferried across town by hitching a ride on the buses of the Amherst PVTA transportation system.

The University of Massachusetts at Amherst Diverse Outdoor Mobile Environment (DOME) Project is researching technology for disruption tolerant networking (DTN) systems (via NetworkWorld).

DieselNet currently consists of 40 buses each with a Diesel Brick, which is based on a HaCom Open Brick computer (P6-compatible 577Mhz CPU, 256MB RAM, 40GB hard drive, Linux OS). The brick is connected to three radios: an 802.11b Access Point (AP) to provide DHCP access to passengers and passersby, a second USB-based 802.11b interface that constantly scans the surrounding area for DHCP offers and other buses, and a longer-range MaxStream XTend 900MHz radio to connect to our throwboxes. Additionally, a GPS device records times and locations. Our custom software allows us to push out application updates, take mobility, AP-to-bus connectivity, and bus-to-bus throughput traces.

UMass Amherst – DOME website, Nov. 23, 2006

The idea here is to create systems that can route messages without knowing exactly where the message is going, because most nodes are only up for limited amounts of time (an average of 20 percent on DieselNET). So when two nodes are in range, they query each other for the other nodes they are likely to encounter along the route, and they pass messages along based on that information.

Why bother? Well, for one, DARPA has money for this kind of research. And I am sure the military has all kinds of ideas for implementations. Imagine a couple of dozen/hundred/thousand nodes (people who carry a wireless computer or robot/rover devices). If these nodes were moving about in more or less predictable ways, and not scattered too widely, a DTN could relay messages within that group within seconds from one end to another and failures of individual nodes have very little impact on the system as a whole. You can see, perhaps, why the military might be interested in this idea. But I think there might be also very useful civilian uses, like in disaster recovery, exploration of extreme environments (space, under water) and maybe in regular communications.

BTW: if these folks have their way, DieselNET should really be BiodieselNET!

A year ago today Angela Merkel succeeded Gerhard Schröder and became the first female chancellor and the first chancellor from the former East Germany. I was not thrilled. She is a political protegé of Helmut Kohl, aka Birne, the corrupt, corporatist pigdog chancellor from hell of the 80s.

Yet, 2006 so far was a pretty good year for Germany: the Worlcup was a huge success and is thought to have produced quite an economic boost; unemployment is down and the federal government is less in the red than last year. The country was riding a wave of patriotic bliss this summer, during and after the Worldcup. But Ms. Merkel has been unable to harness any of these good news and her approval ratings are not particularly good.

The main issue that drags them down is the inability of Merkel and her “grand coalition” of Germany’s two major parties to pull off a meaningful reform of the countries vast network of entitlement programs. And Germany has problems with a growing tide of hate, racism and antisemitism – especially in the east.

Internationally, Germany has to figure out if it wants to be a “major player” and commit troops to more dangerous assignments in “nationbuilding” efforts, like in southern Afghanistan and “peacekeping” missions like in Lebanon. If so, there has to be a clear commitment to such missions, AND there has to be political leadership that creates the environment that properly supports such missions. Otherwise the military will be stuck in impossible missions without a clear mandate. Merkel’s administration has shown little leadership in this issue.

Leadership. A vision for the country. That’s what is needed. Schröder is a flamboyant, somewhat charismatic leader. Merkel is none of that. But neither has shown a clear vision for Germany. Schröder was just worried about his career. And Merkel? what makes her tick? I think that Gemany needs some reforms and a real vision for a truly unified country. Germany does not need to be a “global player” – the country needs to get its house in order. Is Merkel the leader to bring Germany on track for unity, prosperity and social justice? So far I don’t see that.

Last week I spent two evenings getting 200 liters of veggie ready for processing. After I filtered the oil, I pumped it into the waterheater and heated it to 120 Deg. F. Then I pumped the warm oil into an empty tank to evaporate the water and to dry the oil. Yesterday, I finally got the batch going – my first 50-gallon (200 liter) batch of biodiesel. When I add the 40 liters/10 gallons of methoxide the reactor is just about full to capacity. The batch is settling now, and this afternoon I’ll pump it out and start washing it.

Last weekend I drained the last 25 gallons of oil from my outside storage tank and I was surprised about how wet this stuff was. That would explain whey the last batch was so soapy. So this time I used only oil that I had stored inside in buckets and I decided to go through the trouble of drying the oil. Now I’ll just have to figure out what to do with the wet oil. Probably I’ll heat it and try to dry it. That’s not great for the energy balance for the fuel, but I’d hate to waste the oil.

Yesterday I also built another wash tank for the biodiesel. I built a sturdy 2-foot-high platform from some 2x4s and some plywood. Then I took a 55-gallon plastic drum, cut out the bottom and set it on the platform upside down with a drain valve at the bottom, made from PVC pipe. Now I should be able to process the entire 50-gallons of biodiesel when the batch is ready to be washed. The previous batch was a 40-gallon batch, and I had to process the biodiesel in two parts, 20 gallons at a time. That was pretty tedious, especially since the batch was so soapy. This batch should be a big improvement.

Wolf Biermann’s interview mit dem Spiegel Online ist fasziniered. Der Barde spricht von Zufall und Notwendigkeit, von Kulturschock, Kommunismus und Käsetorte.

Jede Veränderung, die man wagt, hoffentlich zum Guten, zum Besseren, wird von manchen Leuten mit dem Vorwurf des Verrats quittiert. Wenn man zu den Menschen gehört, die immer wieder über alles neu nachdenken, im Lichte neuer Erfahrungen zu neuen Haltungen und Positionen kommen, dann ist man ein Renegat. Im allerbesten Sinne! Denn das war immer so in der Menschheit! Der berühmteste Renegat heißt Martin Luther, der schlägt den Papst auf den Kopf, nicht mit einem Knüppel, sondern mit Gottes Wort, mit einer Bibel. Und mein Vater Dagobert Biermann, Werftarbeiter in Hamburg, wäre von seinen Genossen totgeschlagen worden, wenn die Nazis ihn nicht ins Gefängnis gerettet hätten. Weil er nämlich in den wütenden Auseinandersetzungen von 1932/33, also vor Hitlers Machantritt, ein so genannter Abweichler war. Nicht weil er mit Trotzki sympathisierte, sondern er hatte die blödsinnige, falsche Idee, die Kommunisten müssten zusammen mit den Sozialdemokraten gegen die Nazis kämpfen. Und deswegen wurde er geächtet, als Renegat. Sie sehen, ich bin der Sohn meines Vaters.

SPIEGEL ONLINE – 10. November 2006

November 9 has been a fateful day in German history. The März revolution was started, the emperor was dethroned and the Berlin Wall fell on that day. During the night of that fateful day in 1938 German Nazis damaged or destroyed “1574 synagogues (constituting nearly all Germany had), many Jewish cemeteries, more than 7,000 Jewish shops, and 29 department stores. Some Jews were beaten to death while others were forced to watch. More than 30,000 Jewish males were arrested and taken to concentration camps; primarily Dachau, Buchenwald, and Sachsenhausen.” (Wikipedia)

Today, however, there is a reason to celebrate: today the new Ohel Jakob Synagogue was opened (de) in downtown Munich. The complex includes a museum, a community center and a school, and it is the largest new synagogue in Europe since WWII.

The Jews are back in town – that’s awesome! Judaism is finally an “official” religion in Germany with the same legal status as the Catholic and Lutheran Churches.

Germany is home to the third largest number of Jews and the fastest growing Jewish population in Europe. There are currently more than 105,000 members of the Jewish community living in Germany – although this estimate does not include the many Jews not affiliated with the country’s main Jewish organization, the Central Council of Jews.

Germany.info, Nov. 9, 2006

Still, it is not all sunshine and brotherly love in Germany. The Neonazis are on the offensive and racist and antisemitic aggression are not infrequent. In October, players from the Jewish football (soccer) club TuS Makkabi Berlin(de) walked out of a game against VSG Altglienicke because spectators hurled antisemitic insults at the players.

Recently, the University of Leipzig published a study(de) where 1 in 4 Germans expressed the desire for a single party and a strong leader to run the country. It comes as no surprise to me that they also found pervasive nationalist, racist and antisemitic attitudes across all social strata. Forty percent of respondents found Germany to be “überfremdet” – overrun by foreigners!

This fear of foreigners, xenophobia, is a fear that lives in all of us. It is a fear borne out of weakness and lack of self esteem. And it is a sentiment rooted in helplessness and a way to attempt to assert control over one’s life. This fear, and the pain and violence it can produce is not a uniquely German problem. But Germany has a special responsibility to face that fear and deal with it because of the incredible pain and destruction the Nazis wrought across Europe and the World, and in particular because of the incredible pain and destruction inflicted upon the people of Jewish faith and tradition. This is not guilt. I feel no guilt. I do feel responsibility and a strong desire to reconcile and make peace and make friends.

The only way to overcome this fear is to learn and make friends. We need Jews in Germany to help defeat this fear by showing flag and sharing their culture with everyone. Jewish culture was once the beating heart of Germany. Things will probably never be the same, but I know that Jewish culture will once again be part of, and enrich, Germany.

Shalom!

The Democrats are celebrating a pretty significant victory. Personally I like the sound of Republican heads popping whenever someone says “House Speaker Pelosi” … try it:

House Speaker Pelosi … pop pop pop

House Speaker Pelosi … pop pop pop

House Speaker Pelosi … pop pop pop

House Speaker Pelosi … pop pop pop

House Speaker Pelosi … pop pop pop

This is fun!

:-)

However, I know two jerks who probably had the worst week ever.

Let’s just hope the Democrats have a plan for victory. It one thing to win an election after the ruling party spends the better part of this year self-destructing in a swamp of corruption scandals, sex scandals and sheer stupidity. But to come through after the election, and present a coherent strategy for success and a competent leadership, that is a whole different story.

Especially the leadership issue is a serious challenge for the Democrats. Who calls the shots? I guess that Pelosi just got a lot more powerful, which may be good. She is tough. But what about Reid? And Dean? And the Clintons? I guess we’ll find out.

… is tyranny. I pay taxes and I pay attention to politics, but I cannot legally vote in the US. I know, I am a lousy excuse for a patriot, but I do care about this country (my adopted one, the USofA). No, I don’t fly the American flag on our porch. I do not believe that a national flag is a piece of decoration. I don’t fly the German flag, either.

Why do foreigners not have the right to vote in the place where they live (and pay taxes)? It is unfair, un-democratic, and un-American. We do our part, so we should have a say in who runs the place. Maybe even help run the place. How does getting citizenship make me more qualified to vote? I don’t see how the two are connected.

Across Europe, the idea that foreigners can vote, especially in local and regional elections, is gaining traction. Yet in the US this appears to be a non issue, despite this country being a much more immigration-oriented place than most European nations. So all that’s left for us to do is to send money to the candidates we support. Cynics might argue that sending a couple hundred bucks to a candidate stands a better chance to make a difference than casting a vote. I say that all the money in politics and in elections is the cancer that is killing democracy in this country. But while many Americans are increasingly turned off by politics and apathetic, foreigners are quite motivated to participate, even though we may have our reasons to keep our foreign passports.

Of course, not having to pay income taxes would be a compromise I’d be willing to consider …

Piedmont Biofuels in Moncure, North Carolina, has openings for interns next year (see flyer). If I were 20, I’d jump on this one myself! This is a great opportunity for a “total immersion” experience in the biofuels-powered, sustainability-focused lifestyle on a small biodiesel refinery/produce farm in rural North Carolina. Contact Matt if you’re interested (see the flyer for his email address).

Piedmont Biofuels is a cooperative run agriculture operation with strong interest in sustainable practices and renewable energy. Our farm consists of a small acreage market garden and oilseed crop research.

A main portion of our operation is a biodiesel research production facility. We currently produce biodiesel for our farm’s diesel tractor from waste vegetable oil. Piedmont Biofuels is also researching bioregionally sound oil producing crops for on-farm energy production. We also dedicate our building practices to recycling and utilizing varied green building like cob, earth plaster, and Hebel block. Other farm projects include a solar thermal heated production facility, a PV (photovoltaic) powered Biodiesel fueling station, glycerin refining and composting.

Piedmont Biofuels website, Nov. 2006

To be clear: this is only for enthusiasts – this is not a cushy internship, nor a hippie vacation. This is hard work, from chopping firewood to hauling waste veggie – they will work you to the bone. But you get to work with some real trail blazers in biofuels production, and you will come out of this internship with valuable experience from the cutting edge of sustainable lifestyles.

The Senegalese department of Agriculture last week announced a collaboration with Brazil and India to begin producing biofuels in Senegal. As part of the program “retour vers l’agriculture” the government aims to replace Senegal’s oil imports with homegrown fuel. A pilot project calls for 4000 hectares of jatropha for vegetable oil to produce 10 percent of Senegal’s fuel in the country.

Apparently, Senegal is in the forefront of African countries seizing upon an opportunity to rid themselves of their dependence on imported fuel. Expensive fuel is one of many factors that burden countries like Senegal. Biofuels leverage the domestic resources and keep wealth within the country, instead of sending hard-earned money abroad to the already rich oil companies in Europe and the US.

This is a good example of initiatives that will have a much bigger long-term impact on economic and social development in African countries than “big development aid” campaigns. Before we pledge a certain percentage of, say, the US budget to development aid, we should first stop American and European companies and governments from sucking the wealth out of Africa and from fueling conflicts with military aid. We should support Fair Trade and sustainable business practices, like micro-loans.

Secondly, development aid needs to help African entrepreneurs and governments develop economic strategies that focus on value-added, not on exporting raw materials. And development aid needs to use local solutions and know-how to solve problems, instead of parachuting in and imposing “solutions” without regard for the problems.

Finally, the most difficult, and perhaps the most important aspect of development aid ought to be “leadership” development. Identifying and supporting leaders at all levels of society and providing support must be a priority, along with encouraging and supporting access to education and information for everyone. These are the building blocks of a participatory, democratic society, which is, in turn, the foundation of economic opportunity for everyone.

P.W. Botha died Tuesday evening. As the president of South Africa from 1978 – 1989, he was a champion of the system of institutional racism in South Africa known as apartheid. When black South Africans asked for freedom and demanded to be heard, he told the Afrikaners not to listen. He refused to free Nelson Mandela. And P. W. Botha said he had no regrets.

On our trip to South Africa almost three years ago we stayed in Pretoria for a few days and we got a glimpse of Afrikaner culture, especially on our visit to the Voortrekker Monument. Learning about Afrikaner history from their perspective made it much clearer why the Afrikaner people in particular were so vulnerable to the idea of apartheid. Not all Afrikaners, of course, and there were, and are, many other racists.

To be clear: none of what I learned in any way justified or even completely explained apartheid, or any form of institutionalized racism. But I found it worthwhile to learn more about Afrikaner culture.

Beyond the Voortrekkers and the apartheid legacy, I found a resourceful, modern, complex people that’s slowly adapting to a new social and political reality. But I also clearly recognized the shadow of the “old South Africa” in the looks we got when our kids played with a gaggle of black kids on a Pretoria playground, or when we showed up as a mixed-race group on a beach in KZN.

I see Botha’s death as another milestone on the path to the new South Africa, and to a new Afrikaner culture. A culture that contributes its patriotism and resourcefulness to the leadership in South Africa. And a culture that cheerfully shares playgrounds and beaches with all South Africans.

One of Africa’s most successful entrepreneurs, Dr. Mo Ibrahim, has set up a foundation and announced a $5 Million prize for the most effective, least corrupt, and all around best-of-the-best African leader. (HT to BRE)

In an interview with the Financial Times newspaper, Mr Ibrahim, 60, said leaders had no life after office.

“Suddenly all the mansions, cars, food, wine is withdrawn. Some find it difficult to rent a house in the capital. That incites corruption; it incites people to cling to power.

“The prize will offer essentially good people, who may be wavering, the chance to opt for the good life after office,” said Mr Ibrahim.

Prize offered to Africa’s leaders, BBC News, 26 October 2006

Pretty clever. Pay them to be good. I think that, in general, politicians are underpaid – and not just in Africa. I am not so naive to think that money is a cure-all for corruption. But if the salaries of public office were halfway competitive with the industry, there’d be fewer nutcases running for office. OK – nevermind that – not fewer nutcases, just more halfway sane, pragmatic technocrats.

In Africa this problem is much worse. Not only is politics extremely dangerous in some parts, but there is also very little in terms of retirement benefits, beyond what you can squirrel away during your time in office. That’s not a situation that provides a lot of incentive to most sane, intelligent people to chose public office as a career.

This initiative deserves the spotlight also because it highlights the key problem Africa faces: leadership, and the lack thereof. Just the other day I asked a Togolese friend “Mon frère, what is Africa’s biggest problem?” I explained that if he could solve one problem on the continent, what would it be? Malaria? AIDS? Hunger? Poverty? Celebrity adoptions?

“Leadership!” He said. Without decent leaders democracy cannot work. Without democracy, there cannot be much progress, social or economic. Without progress we can never solve poverty, hunger and the public health crises. And there will always be another genocide somewhere.

This is why I am skeptical about those “big money” campaigns by Americans and Europeans to raise huge sums for development aid for Africa. It’s like they are refueling and changing the tires on a racecar that’s going the wrong way on the track because the driver is drunk. Dr Ibrahim says: let’s reward the driver who can drive well! Congratulations!

Here is a recent update about the cleanup from the Probo Koala toxic waste scandal:

‘We do these kinds of operations all around the world, but this is big,’ Alwin Booij, managing director Tredi Internationale, the French firm contracted to handle the cleanup told Deutsche Presse-Agentur dpa Thursday.

So far, Booij said, his teams have removed more than 6,000 tons of contaminated soil and toxic liquids from 18 sites around Abidjan, a city of around five million inhabitants. The 141 tanker and box containers aboard the MN Toucan constitute only the first of an expected four shipments.

[…]
Today, Ivorian authorities are carrying out no fewer than five inquiries into the affair. Two top Trafigura executives are among ten men currently being held in an Abidjan prison pending the results of a criminal inquiry. And police in the Netherlands are looking into an attempt by the Probo Koala to offload its cargo in Amsterdam in July.

The Ivorian government is also concerned with recuperating cleanup costs, which are likely to run well into the millions.

‘We’re talking about six thousand tons of very hazardous waste to repack, transport, and incinerate,’ Tredis Booij said Thursday. ‘There are big bucks involved.’

[…]
The MN Toucan left Abidjan late Friday night with its poisonous cargo bound for Le Havre, France. From there the tankers and containers will be transported to an incinerating facility outside Lyon for disposal. But it leaves behind it unanswered questions.
Ivory Coast toxic cleanup nears end, but questions remain, by Joe Bavier, Oct 28, 2006

Ten innocent people dead, thousands of people sick, and millions of Euros/Dollars wasted in cleanup cost. At least two of the executives of Trafigura are sitting in a prison in Côte D’Ivoire! If they are found to be responsible for this mess they deserve to rot in the deepest, darkest hole in that prison for the rest of their lives.

Can microbrewing save the world? In a recent article on Alternet, Chris O’Brien looks at the global and historical perspective of microbrewing: revolutionary America and the colonies’ dependence on porter from England; the rich variety of local brews of Africa and South America being replaced by imported mass-produced beer, and the rich brewing tradition in Germany due to the Reinheitsgebot (purity law) of 1516.

O’Brien puts forth the popular “buy locally” anti-globalization argument, that equates globalization=big beer=bad beer. I do like his “beerodiversity” point. I am all for supporting local brewing diversity. But I also do appreciate a globalized selection in the local(ly-owned) beer store. Most of the beer I drink is made in North Carolina. This state has some fine brews, like Highland and Foothills, and there are some very good local micro-brews as well.

But I also like having a large selection of imported and US beers available. I like my Weihenstephan weizenbier, or a Celebrator, or even just a Guinness. The latter in particular, is a great example of “big beer” not necessarily being “bad beer.”

To me, beer and life is all about diversity. Diversity grows locally, but it can also spread globally. So yes, microbrewing can safe important aspects of the world, like local tradition and flavor. So let’s save the world – one pint at a time.

Prosit!

Ramadan is ending and the Muslim world is getting ready for Eid al-Fitr – perhaps the most cheerful Muslim holiday.

I have great memories of celebrating Eid with friends in Morocco in 1990. I had been biking around the country for most of Ramadan, and got back to Fès just in time for Eid. I had mostly observed the fast voluntarily, and because I found it – uh – awkward to light up, or eat during the day and torture everyone around me. When traveling on the bike, I did drink water during the day, as this was a total necessity. Also, travelers are actually exempt from the fast. Not that strict observance rally mattered to me on religious or other grounds. It was rather a point of cultural sensitivity and curiosity to take part in this amazing phenomenon of Ramadan.

Celebrating Eid with my friends in the medina in Fès was one of the greatest experiences and privileges of my traveling days. I’ll never forget the sights and sounds of the Fassi decked out in their finest, the hospitality and the great food!

Happy Eid!

The ship that was involved in the deadly toxic waste scandal in Ivory Coast has left the Baltic port of Tallinn, after unloading toxic waste similar to what turned up in sewers and municipal dumps in Abidjan a few months ago. According to the Baltic Times, the Probo Koala pumped 600 cubic meters to another vessel, to have it processed by EcoPro in the port of Sillamae.

In the meantime, two executives of the charter company Trafigura were arrested in Côte D’Ivoire. The company still rejects direct responsibility for the disaster, but has promised full cooperation with the investigations.

Reportedly, the Probo Koala was used (illegally) as a floating refinery, to use chemical processes to extract fuel from low-grade crude oil.

On our trip to Iceland last year, I fell in love with this unique country, with its stark, fragile natural beauty and its friendly, quirky inhabitants. I learned a bit about the Icelanders, and I think I understand why they want to resume whaling.

Please don’t do it, Iceland.

There are many better ways to assert your independence and cultural heritage. How about exporting Icelandic beer or brennevin. Why not put all this effort you put into whaling into, say, making hákarl a hip, sexy appetizer for yuppies. That would make basically the same point, and it would not harm a sentient species.

I’d love to visit Iceland again, one day. But I won’t, until you call back your whalers. And I won’t recommend Iceland as a tourist destination until you leave those poor whales alone. Sorry.

Last weekend I got my latest batch of homebrew ready and I made some modifications to the reactor. I added a intake valve, so that I can easily use the pump as a transfer pump from the washtank to the drying tank and from the drying tank to the storage tank (on the right). I also moved the the temperature gauge up a bit; in front of the intake for he methoxide, so that I get better temperature readings while I am adding the methoxide to the process.

The additional intake valve was called for because the oil intake is gravity fed from the oil storage and the intake is at the lowest point, so I cannot easily unhook it to use that intake for transfer. So instead, I leave it alone and plug another hose into the new one and conveniently pump from one tank to the other. I can also use it to completely drain the entire plumbing, which is useful.

One of my fellow biodieselers started calling this setup the “apple turnover” design, when I described it. That is because it is an appleseed reactor with the water heater installed upside down to facilitate better, more complete draining of the reactor.

Click on the image for a closer look at the plumbing.

Looks like I found a good source of methanol for my fuel production. Last Thursday I drove out to the Roxboro Motorsports Dragway and procured a 55-gallon drum of this critical ingredient for biodiesel. Racetracks have methanol supplies because they use it as a racing fuel – “racing alky.”

So this German guy and this African guy show up at this drag strip way out in the country in a Volkswagen Jetta, load a drum of “racing alky” on their trailer and talk about making diesel fuel out of used fryer grease. I bet that was the cross-cultural experience of the month for the guy who sold us the methanol. However he did mention that they do use quite a bit of fryer oil at their concessions, and that we could have it if we wanted it. Next time I go there, maybe I’ll drop off a plastic drum for them to collect the fryer oil.

One thing that worked great for transporting the 55-gallon drum was laying down a crate upside-down, and then dropping the drum sideways into one of the two openings at the bottom of the crate. Secured with a couple of straps, this was a great way to transport the methanol.

So that night I worked from 8 to 11 to start a new batch of biodiesel, which I am washing right now.
Praise the lard!
