When we think about geothermal energy, we usually think about somewhere like Iceland, which has more volcanoes that it knows what to do with. But according to a new study funded by Google.org, the U.S. has the potential to easily, right now, replace all of our coal-fired power plants with clean and endless geothermal power.
In 2008, 85.8% of all of the plastic used in the United States ended up in a landfill. It wasn't reused or recycled, and it wasn't turned into energy. A new study from Columbia University says that turning landfill-bound plastics into energy instead would not only produce energy, but save money and the environment all at the same time.
The Large Hadron Collider over in Europe may be making all the physics headlines as of late, but the U.S. Department of Energy is trying to scrape together between one and two billion dollars to build a particle physics lab deep in an abandoned gold mine underneath South Dakota.
In what can't possibly fail to be a symbolic gesture, old coal mines in Germany are being repurposed into giant storage tanks for wind energy.
Big waves can be bad news for coastal areas, and over time, even moderate wave action can erode beaches down to nothing. In one of those schemes that sounds crazy but isn't, Chinese researchers have developed a system that uses concrete cylinders to render coastlines effectively invisible to incoming waves.
Japan has taken a recent interest in alternative forms of power generation, and one of their latest ideas is this 160 foot tall hexagonal tower that works twice as efficiently as conventional wind turbines, without giant spinning blades of death.
By mimicking the essential process that allows plants to produce energy, an MIT researcher has managed to create electricity out of water more efficiently than conventional solar cells, to the point where one and a half bottles of wastewater could power an entire house for a day.
With so many soldiers being deployed in hot sunny places, it seems like a no-brainer to put all that blazing sunlight to good use. So a British team has developed a special photovoltaic fabric, that captures the sun's rays to provide juice for all of a field soldier's electronic gadgets.
If you're going to build a giant waste incinerator, you might as well design it so that people can ski down its sides. Oh, and you should also make it blow smoke rings, and then shoot those smoke rings with lasers.
To build a solar power plant, you need two things: lots of energy, and lots of silicon. The Sahara desert can provide scads of both, and by using power plants to 'breed' more power plants, the Sahara Solar Breeder Project will theoretically be producing enough green energy to power half of humanity by 2050.
