How Tesla Batteries Are Powering an Energy Revolution. Those Tesla Motors lithium-ion battery packs aren’t just powering electric luxury sports sedans for the 1 percent any more. They’ve started appearing in a small number of California homes to store electricity generated by rooftop solar panels, and businesses that want to cut their utility bills by charging the batteries with a rooftop photovoltaic array and then tap that power when demand—and electricity rates—spike.
'Artificial leaf' widens reach with self-healing capacity - Nobody does solar power better than a plant, right? Technology is bridging the gap between biology and engineering. An artificial leaf has been created to help bring electricity to developing areas, by mimicking photosynthesis. Now, it has been updated and can self-heal and run on dirtier water, more similar to the environment where it will be used.
