Remember how, in Back to the Future, Doc dug through the garbage to run his time-traveling car? Pretty smart idea, to use a fairly reliable fuel source that was going to waste anyway (pun intended.) Now, imagine the same idea—only cleaner, more efficient, and without the smell of week-old bananas.

Cyclone Power Technologies of Pompano Beach, Florida, has unveiled their working prototype biomass power generator, which produces power from burning dry plant matter (think wood pellets, grass clippings, corn stalks, and wood chips.) The generator system works fairly simply. Burning dry plant matter in the biomass combustion chamber produces heat. This heat runs an attached external heat engine, producing mechanical energy.  An alternator then converts this mechanical energy into as much as 10kW of usable electricity.

This engine could power homes, farms, or other small buildings that have plenty of “vegetative waste and byproducts” lying around—as in the grass clippings from mowing the lawn or fall leaves. The only catch appears to be the availability of dry plant matter—this technology probably won’t spread in urban or highly developed areas, where yards are small or non-existent. Those areas, like Manhattan, will just have to wait for the engine that runs on chewed gum, cigarette butts, and discarded Starbucks cups.

Gliocladium roseum. Say it three times fast.

Major businesses and universities are racing on a variety of research fronts to see who can harness fuels from natural sources cost-effectively, and Gary Strobel at Montana State University may have found a unique two-pronged solution in the form of a small mushroom.

G. roseum potentially changing the world in a petri dish.

Nicknamed “superfungus,” this mushroom, found on the Ulmo trees in Patagonia, Gliocadium roseum has been discovered as potential source of bio fuel by accident in an experiment originally designed to test how different fungi responded to antibiotics. Researchers were surprised to find G.roseum had not only survived, but thrived after exposure where every other fungi was dying. Naturally absorbing carbon dioxide? Prong one check.

The unusual benefit to G. roseum is not in the input, but what it puts out: diesel. Or something very close to it, dubbed “mycodiesel.”

This is where the fungus’s potential lies. In eliminating many of the additional steps typically needed to harness fuel from plants like corn, G. roseum is appearing to already be cost-effective. Scientist’s ability to synthesis the benefit parts of the mushroom in the lab also nip fears of new found business interests in the rain forest in the bud.

Most biofuels, even when very efficiently harnessed, are not a magic bullet to the growing energy crisis. Discounting often-harmful hydrocarbons as a byproduct, biofuels in a perfect world still produce carbon dioxide. G. roseum, by directly taking in carbon dioxide and excreting mycodiesel, is like few other organisms that are coming to be seen as potential golden eggs. That produce diesel gas.

And if that weren’t enough, secondary rounds of research are revealing that the mushroom also produces potent antibiotics as a byproduct.

As G. roseum is moved into the lab and researchers begin testing it to the demands of a level of fuel output useful to our needs, it is yet to be determined if “Superfungus” will live up to its name.

You may have seen the movie “Fast Food Nation.” You may have read the books An Omnivore’s Dilemma and In Defense of Food: An Eater’s Manifesto. Now playing, but probably not in your local theater, is “Food Inc.”, a movie about the food industry and the way our grocery stores are supplied. It has great insight and is a worthy reminder about why we should buy local and organic.

Even the term “locavore” has officially been added to Webster’s dictionary. Let’s take all of this knowledge, media, and news and apply it. Eat locally, and until you get to the grocery store, check out the trailer below.
