“bionic leaf” converts solar energy into a liquid fuel

[3mer]

Harvard scientists have created a “bionic leaf” that converts solar energy into a liquid fuel. The work—a proof of concept in an exciting new field.
Today, it is far more efficient than a field-grown plant, which captures only 1 percent of sunlight’s energy. He says he can reach efficiencies of 70 percent to 80 percent of the underlying solar-wafer technology, which is improving constantl
