Abstract :
Ask any scientist to name Earth\´s most abundant source of energy, and the answer comes quickly: sunlight. In one hour, the Sun strikes Earth with enough energy to power the entire planet for a year. "There\´s nothing that compares to the Sun. Everything else pales in comparison," Daniel Nocera, the Henry Dreyfus Professor of Energy in MIT\´s Department of Chemistry, says. With gas and oil prices at all-time highs, it\´s only logical for scientists to try to harness some of that solar energy. Three projects at America\´s MIT are leading research into the area, looking at mimicking photosynthesis, producing a cost-efficient solar power system and finally designs for flexible photovoltaic materials that may change the way buildings receive and distribute energy.
