Solar power breakthrough makes energy self-sufficiency a reality In a revolutionary leap that appears likely to transform solar power from a marginal, boutique alternative into a mainstream energy source, MIT researchers have overcome a major barrier to large-scale solar power: storing energy for use when the sun doesn't shine. MIT researchers have hit upon a simple, inexpensive, highly efficient process for storing solar energy that mimics photosynthesis. Homeowners will soon be powering their homes in the day with solar cells, while also producing hydrogen and oxygen to power their car and home at night. Electricity-by-wire from a central source could soon be a thing of the past ... more
