Solar-powered hydrogen reactor stores heat for overnight use
The Sun can provide an unlimited amount of energy, but there's one major downside – night. For roughly half the day facilities and devices that rely on solar power have to shut down or store extra energy, and the process is particularly disruptive to concentrated solar power (CSP) plants which work on heat.

MIT's thermal resonator generates electricity from the air's daily temperature cycle
Energy is all around us – we just need to work out how to tap into it. Now a team from MIT has developed a device called a thermal resonator, which could essentially pull electricity out of thin air by taking advantage of gradual ambient temperature changes over the course of the day.
