Solar energy by day, thermo-electric energy by night

post-image
Solar energy is great while the sun is shining.  But not so useful once night falls. Most people think batteries are the answer, but Stanford University researchers have been working on another option.  TEG's (Thermo-electric generator) are energy conversion devices. Basically, by using the temperature differential between one side of the panel and the air, more electricity can be generated ( both during the day and at night). Even better TEG's are reliable, safe, affordable and available right now.https://twitter.com/i/status/1543377040996548614
