(Phys.org) —Oceans carry enough potential energy to make a difference. The devil is in the details. Finding a way to harness all that power had prevented wave power from being seen as a practical solution but now technologists ...
Scientists in China said Thursday they had designed a "smart" window that can both save and generate energy, and may ultimately reduce heating and cooling costs for buildings.
