Eat more stuff – we need the fuel

with one comment


And while we’re at it let’s get goats into the act.

But first, UCLA researchers are studying the use of the human feces as biofuels to power cars. David Wernick, graduate student of UCLA, notes that poop is an untapped resource that only gets flushed in toilets.

In the US, just counting animal manure, more than 1 billion tons of poop are produced yearly. But Wernick and his colleagues are also trying other materials to produce new kinds of biofuels such as sewage waste, plant matter, cellulosic matter and carbon dioxide from the atmosphere, Gizmodo reported

The UCLA team plans to engineer the bacteria in human waste by breaking down the proteins in excrement and other waste rich in protein such as wastewater algae and byproducts from the fermentation of beer, ethanol and wine. Wernick believes that the re-engineered bacteria, when it uses the protein to produce poo-based biofuels, would result is the vehicle running without a need to adjust its automotive parts.

BBC recently reported that fungi found in goat and sheep stomachs can break down vegetation in a way that may be useful for biofuel production. Most biofuel in the United States comes from crops such as corn, but growing corn takes a lot of land, and using it for biofuels may drive up food prices. So the industry is increasingly looking toward nonfood sources of biomass like grass and wood. In a study published in Science, researchers show that fungi isolated from the feces of goats and sheep can break down wood better than the standard processes in place. Plus, these fungi can change which digestive enzymes they produce in response to what they are eating, making them more flexible than traditional methods.

Renewable energy is all about looking at everything in new ways, including our own poop…oh, and goats.

Update on lithium ion batteries:

Starting on April 1, the International Civil Aviation Organization (ICAO) will ban shipments of lithium-ion batteries as cargo on passenger aircraft due safety concerns. According to Lloyd’s Loading List.com, the decision is “binding on all (191) ICAO Member States and therefore the airlines which operate in those States.”

This is the latest in a national and international efforts to restrict shipments of lithium-ion batteries as cargo. Last month I posted that the Federal Aviation Administration issued a “safety alert” urging U.S. and foreign commercial passenger and cargo airlines to conduct “a safety risk assessment to manage the risks associated with transporting lithium batteries as cargo.” The FAA also issued a guidance to its own inspectors to help them determine whether airlines have adequately assessed the risk of handling and carrying lithium batteries as cargo.
