Sunlight has the greatest potential of any power source to solve the world's energy problems, Daniel Nocera, the Henry Dreyfus Professor of Energy at MIT and researcher on the project, said in a statement. In one hour, enough sunlight strikes the Earth to provide the entire planet's energy needs for one year.
The problem, however, is how best to harness that energy.
The research is a "giant leap" toward generating clean, carbon-free energy on a massive scale, said James Barber, a biochemistry professor at Imperial College London who was not involved in the solar project.
Nocera said he's hopeful that within 10 years people will no longer power their homes using electricity-by-wire from a central source. Instead, homeowners will be able to power their homes with solar power during daylight hours and use this new energy storage method for electricity at night.
