Biofuels are more environment-friendly than fossil fuel, sure, but is it worth the price? According to a leaked report, Biofuel production has forced global food prices up by as much as 75%. When you use food to create gas instead of eating it, a tug-of-war was inevitable. Read more about it in the full article.

A water-powered car. Sounds like the science doesn't hold H2O, but someone apparently refused to believe it when everyone else said it can't be done. Ok, honestly, I hope this is the real deal, but you can judge for yourselves. Watch a video of the car in action in the full article.

Almost two decades ago, a group of scientists presented a report of the existence of cold fusion. The report was bogged down in controversy and ever since then, cold fusion has mostly been looked upon with skepticism. Cold fusion's promise of cheap and efficient energy became a dream for many. Now, a retired physics professor claims that he has found the secret to cold fusion. Is this the real thing, or just another dead end?

First hydrogen-powered cars, and now hydrogen-powered mobile phones. Will these alternate sources of fuel and power eventually become mainstream someday? The possibility doesn't seem far off at this point, with STMicroelectronics working on a mobile phone power system that uses hydrogen as a reserve power supply. More in the full article.

Methanol fuel cells have been found to be an efficient and sustainable replacement for fossil fuels. The one thing preventing this device from hitting the mass market is its price since these devices need a catalyst made of platinum, a very expensive metal. However, a researcher from the University of Basque Country may have just the solution to drive the cost down. To find out more, head on over to the full article.

There's a hot little topic running in the socio-political, environmentalism picture, and it involves a regulation that the UK's Department for Transport has in mind for the reduction of carbon dioxide emissions. The deal is that the rule, if implemented, will probably hurt the world more than do its share of good, and even pro-environment organizations such as Greenpeace agree. Learn why at the full story.

Green is in. Thanks to the introduction of eco-friendly technology, cell phone base stations in Africa will soon cut their use of diesel fuel by 80%. Good news for the environmentally conscious. More details in the full article.

It seems that more and more start-up companies are being innovative in their efforts to be environment friendly. Last time, Konarka Technologies revealed how it makes cheap solar film cells using an inkjet printer. Now 1366 Technologies aims to have multi-crystalline silicon solar cells edge out coal-based electricity.

More "green" innovation follows in the full article after the jump.

The Federal government has given permission to Washington state and Oregon to issue death sentences to a common killer: Sea lions. While they may seem cute, feeding frenzies orchestrated by these marine mammals are contributing heavily to the dwindling population of migratory Pacific Northwestern salmon. Find out more in the full article up ahead.

If you're thinking of replacing that old inkjet printer of yours, you may wish to consider giving it to  Konarka Technologies instead. The reason? Konarka has found a way to make affordable solar film cells using...you guessed it: an inkjet printer. More on this innovative process in the full article, right after the jump.
