Scientists at Stanford University have demonstrated for the first time that heat from the sun and coldness from outer space can be collected simultaneously with a single device. Their research, published November 8 in the journal Joule, suggests that devices for harvesting solar and (space energy will not compete for land space and can actually help each other function more efficiently.
Renewable energy is increasingly popular as an economical and efficient alternative to fossil fuels, with solar en...
