MIT engineers have come up with a conceptual design for a system to store renewable energy, such as solar and wind power, and deliver that energy back into an electric grid on demand. The system may be designed to power a small city not just when the sun is up or the wind is high, but around the clock.
The new design stores heat generated by excess electricity from solar or wind power in large tanks of white-hot molten silicon, and then converts the light from the glowing metal back into electricity when it’s needed. The researchers estimate that such a system would be vastly more affordable than lithium-ion batteries, which have been proposed as a viable, though expensive, method to store renewable energy.

NASA Administrator Jim Bridenstine announced Thursday that nine U.S. companies will compete to deliver experiments to the lunar surface. The space agency will buy the service and let private industry work out the details on getting there, he said.
The goal is to get small science and technology experiments to the surface of the moon as soon as possible. The first flight could be next year; 2019 marks the 50th anniversary of the first manned moon landing.
The nine companies, representing seven states, are:
- Astrobiotic Technology Inc., Pittsburgh;
- Deep Space Systems, Littleton, Colorado;
- Draper, Cambridge, Massachusetts;
- Firefly Aerospace Inc., Cedar Park, Texas;
- Intuitive Machines, Houston;
- Lockheed Martin, Littleton;
- Masten Space Systems Inc., Mojave, California;
- Moon Express, Cape Canaveral; and
- Orbit Beyond, Edison, New Jersey.
