There is contention in Sweden over the use of rabbit cadavers as bioenergy to provide heat in Värmland. The rabbits are invasive species, initially pets that were released into the parks in the city of Stockholm. Lacking any natural predators, the rabbits thrive on vegetation, eating their way through the city's central parks. The culling last year set a local record with nearly 6,000 rabbits removed from Stockholm's parks, mostly from Kungsholmen. Some concerned citizens have formed a group, Vilda kaniners värn (Society for the Protection of Wild Rabbits, Google translation). They speak out against the culling and provide alternatives to killing the rabbits, citing methods used in Helsinki (including plant protection) as more humane alternatives.

"Algae is the ultimate biological system using sunlight to capture and convert carbon dioxide into fuel... I came up with a notion to trick algae into pumping more [fuel] out." Craig Venter's Synthetic Genomics partners with ExxonMobil in a $600M project to harvest biofuels from genetically engineered algae. "We have modest goals of replacing the whole petrochemical industry." [previously] [more inside]

Today Boeing completed the first test flight of a commercial jet-liner using a mix of conventional jet-fuel and a fuel created from algae and the african weed jatropha. Boeing hopes that biofueled flights will be common in just three years.

Pond scum saves the planet? In the beginning, there were algae, but there was no oil. Then, from algae came oil. Now, the algae are still there, but oil is fast depleting. In future, there will be no oil, but there will still be algae. ^ Power your ride with pond scum. In some iterations you don't even need light. (we have talked about this before and the fact that CO2 powers the algae production is not insignificant) More details here.

Land turned to biofuels in the US alone in the last two years would have fed nearly 250 million people with average grain needs. Prices of all staple food has risen 80% in three years. 33 countries face unrest because of these price rises. Subsidiziation of Biofuel is driving the poor to starvation. In Bangladesh Biofuel production hits food security. Half of Pakistan population at the risk of food insecurity, warns WFP. Cost of food increases hunger in Nepal. wiki

Biofuels worsen global warming, according to two studies published in Science last week. Current US biofuel policies would double carbon emissions over the gasoline alternative.

The looming food crisis is already upon us. The Institute for Food and Development - Food First - whose Policy is to eliminate the injustices that cause hunger is joined by Green Horizon talking about a global food crisis emerging. By promoting biodiesel as a substitute, we have missed the fact that it is worse than the fossil-fuel burning it replaces. As a result the line between the food economy and energy economy has become blurred. In the United States and Canada, governments are manipulating the market in the biofuels industry.

A Welsh Black Box to make biofuel whilst capturing car fumes

Petroleum from Pond Scum: Dr. Isaac Berzin, founder of GreenFuel Technologies, is working on a prototype that uses algae to convert power plant emissions into biofuels. Good news: It would only take a bioreactor twice the size of new Jersey to supply the entire US with its petroleum needs.

Newsfilter: Spanish firm claims it can make oil from plankton. A Spanish company (Bio Fuel Systems) claimed on Thursday to have developed a method of breeding plankton and turning the marine plants into oil, providing a potentially inexhaustible source of clean fuel.

"I've halved my motoring costs since I started running my diesel Subaru on cooking oil. The car runs just as well and even smells a lot better than diesel."

The police 'Frying Squad' are on the case and "home in on any car smelling like a mobile fish and chip shop". Other than the dreadful puns, are there other reasons why we shouldn't all run our cars on Mazola?
