Lots of people around the country are outfitting their houses with energy-harvesting solar panels, and not just for the environment, but for government kickbacks, as well. Some companies will even foot the bill and install your panels for free, provided they can collect on the federal subsidies. More »

With water shortages looming in the future, we need new ways to clean water that's been fouled by human waste, agricultural runoff and industry. A new article published in BioScience (free PDF link) shows that we can use naturally-occurring algae as a filter. The plants would not only make the water suitable for re-use, but could also allow us to harvest pollutants for fertilizer and even biofuel. More »

It's an awesome solution to a simple problem: you need ridiculous amounts of fuel to get a rocket into orbit. However, if the rocket fuel was considerably hotter, it would be more energetic, and you'd need way less fuel to launch the rocket. So why don't we just shoot powerful lasers at rockets? It's so insane that it just might work. More »

We've seen lamps that run on human blood and examined robots that eat corpses for fuel. Sweden is already using flesh-based biofuel, but it's not humans they're using to heat their homes; it's rabbits. More »

Restaurants across the United States are reporting that thieves are stealing their used cooking oil, turning it into black-market biodiesel made in garage distilleries. In many cities where biodiesel fuel is popular, restaurants can earn up to $1.25 per gallon of the used stuff. Oil pirates, however, are rarely looking to make a buck. They are just whipping up biodiesel for their own uses, cutting out middlemen who go through a complicated certification process with the Environmental Protection Agency in order to distill the fuel from oil.

Dead Space, a new game from Electronic Arts, brings parasitic "we want to kill you, kill you, kill you" aliens back into fashion just in time for next Halloween. In the far future, humans have depleted all of the natural resources on Earth, so private corporations begin sending out enormous ships called "Planetcrackers" that carve off enormous chunks of planets, and then mine them down to their bare essentials. Of course, as often happens in these games, this pisses off an "ancient and malevolent force" who decides to start unleashing hell. In space. More »

In the next year, students at Georgia Tech will be driving cars that run on fossil fuels but don't release tons of carbon into the environment. It's all part of the university's long-term plan to develop vehicles that produce recyclable carbon. Eventually they hope to eliminate fossil fuel from the equation, but in the meantime they are working with an engine that traps carbon emissions for dumping off and recycling at fuel stations. Let's hope they model it on this Swiss zero-emissions car called SAM, which looked cool but was discontinued due to lack of funds. More »
