A team of researchers has developed a cheap, rechargeable and eco-friendly battery that could be used to store energy at solar power plants for a rainy day.
Engineering professor Donald Sadoway on Thursday used an old-school chalk board at the prestigious TED gathering to write the formula for a liquid battery that could one day cut the need for new power plants.
Internet giant Google and investment firm KKR will invest $400 million in six solar plants in California and Arizona, the companies announced Thursday.
New solar cells could increase the maximum efficiency of solar panels by over 25%, according to scientists from the University of Cambridge.
Rays of the winter sun bounce off gleaming mirrors on the tiny lake of Colignola in Italy, where engineers have built a cost-effective prototype for floating, rotating solar panels.
Most of today's power plants--from some of the largest solar arrays to nuclear energy facilities--rely on the boiling and condensing of water to produce energy.
Concentrated solar power technology is an emerging, environmentally friendly way to produce electricity.
