(PhysOrg.com) -- Researchers at Sandia National Laboratories have built a machine that uses the sun's energy to convert carbon dioxide waste from power plants into transportation fuels such as gasoline, diesel, and jet fuel. The system could provide an alternative to carbon sequestration; instead of permanently storing CO2 underground, the CO2 could be recycled and put to use.
It will probably take 15-20 years before the technology is ready for the market, with the biggest challenge being to increase the system's efficiency. The researchers' goal is to achieve an efficiency of a few percent, which is about twice as efficient as photosynthesis' real-world efficiency of 1%. One way to increase efficiency is to develop new ceramic composites that release oxygen molecules at lower temperatures.
