Solar energy is one of the most promising resources to help reduce fossil fuel consumption and mitigate greenhouse gas emissions to power a sustainable future. Devices presently in use to convert solar energy into thermal ...
(PhysOrg.com) -- As computer chips become more powerful, they also become hotter. Nearly all the power that flows into a chip comes out of it as waste heat, and that heat hurts the performance of the chip.
How did the chemical makeup of our planet's core shape its geologic history and habitability?
