Geothermal power, where energy is generated by drawing heat from the fluid found beneath the Earth's surface, is quickly becoming an appealing option. A new mapping tool from the U.S. Department of Energy shows the country's vast geothermal heat potential.
Regardless what you think about the future of phones or wearables or cars, there is one thing nearly everyone can agree on: We will need more batteries. And for that, we'll need more lithium. One startup has its eyes on a new source of lithium: the wastewater from geothermal power plants.
The winter months are some of the busiest travel times of the year, but they're also the most likely time for an airplane to be delayed. The culprit? Icy runways. Wouldn't it be nice and efficient if we could take some of the excess summer heat, save it, and use it to thaw out airports in the winter? Some of the…
Earth runs on massive amounts of heat, enough to melt iron in the core and create our magnetic field, enough to power the constant movement of plate tectonics. Where all this heat comes from is a mystery...but we're getting closer.
Enceladus is home to one of the solar system's most incredible hotspots, churning out 15.8 gigawatts of power. It's even more proof that there's a liquid ocean hiding beneath the ice...but scientists have no clue what's creating all that heat.
John Denver proclaimed it "almost heaven", but a group of geoscientists are implying it's a little more like the opposite. Most of the rest of the world doesn't think of West Virginia as a hot spot, but it is.
If everything goes well, soon we will be able to reach the center of the Earth using 7200ºF flame jets that can go into any kind of material at 100 feet an hour. Wait, "if everything goes well"?
