Power your car... with termites?
The pesky termite could hold the key to creating a green energy future.

Because our cellulosic ethanol technology is so primitive, the biofuel industry currently relies on crops like sugarcane and corn. Instead of using the actual fiber for fuel, the sugars are expelled and the fiber is discarded. This makes for a simple, yet costly conversion to ethanol.
The result -- huge swathes of the rainforest in Brazil have been felled only to be replaced by sugarcane plantations that are allegedly even worse than the slave-run plantations of the 19th century. An article this week in Vice Magazine documents the horrendous working conditions on these plantations.

But what if we had a machine so sophisticated, it could break down anything from a scrap of wood to a clump of dried grass? This machine would eliminate the need to grow massive and costly sugar plantations, preserve our rainforests and allow us to turn anything into fuel.
Well, in fact we do have such a machine. It's called the termite.. or specifically the termite intestine.
Like a cow, the termite has a series of stomachs, each acting as a carefully controlled "reaction chamber" that progressively converts cellulose into fuel. Any homeowner who has dealt with a termite invasion knows the termite's power in converting solid wood into dust.
To give you a sense of just how efficient a termite is, Andreas Brune of the Max Planck Institute for Terrestrial Microbiology says that if you look at the numbers, the termite can turn one single sheet of paper into 2 liters of hydrogen gas. And that is with next to zero energy input, no heat and no toxic chemical additives or byproducts.
The termite's secret is the complex interaction of several powerful microorganisms inside its intestinal track. Researchers have travelled to the homeland of the termite, Costa Rica, to collect genetic samples and are working to crack the termite code. If they are successful a new method for converting nature's most abundant waste product into fuel may be on the horizon.

It would be great to start using bio fuel instead of exploiting Earth's resources each and every day. However, most termite extermination companies are working hard to get rid of all termites and this idea might stumble upon some really unpleasant issues.

Pesky? Machine? Two words in this article that describe the termite. Not very positive, are they? Furthermore, it is very clear here that termites, pesky as they apparently held to be, are just seen as potential commodities, as machines if you will. Never as real animals? Never as fellows in the Community of all Life on Earth?
What would happen with the energy our brother/sister termites would generate at any rate? Would it power your IPod, your computer, your car, your tv? Any kind of.... More

It is so amazing knowing that termites are turning solid materials into bio fuel! Well this study could be a good source of another invention. It's a small loan until payday, not instant money you don't have to pay back. Payday lenders get a bad rap from critics who don't see a value in the service they provide, but short term loans come in handy if you need extra cash.... More
