Heating Buildings With Solar Energy Stored in Sand

Cars That Think

In a region known for long, dark winter nights, Polar Night Energy is building a system in the city of Tampere that can heat buildings with stored solar energy — all day, all night, and all winter long. This means that storing and distributing energy is as important as its generation.

Convert Oil Wells to Solve the Solar Storage Problem

Cars That Think

One of the main impediments to harnessing solar energy is storage. Solar batteries work as a short-term solution, but not when it comes to long-term storage or to power, say, an entire city. Solar energy and oil wells might sound like an odd combination, but the principle is similar to how geothermal energy would be harnessed.

Inside the Universe Machine: The Webb Space Telescope’s Ultra-Reliable Radio

Cars That Think

It’s an ideal location for JWST to observe the universe without obstruction and with minimal orbital adjustments. Any scientific data the JWST collects during its lifetime will need to be stored on board, because the spacecraft doesn’t maintain round-the-clock contact with Earth. The other is the 2.27

CESifo: EVs not the best option for reduction in on-road CO2 in Germany given power mix

Green Car Congress

Over the long term, hydrogen-methane technology offers a further advantage: it allows surplus wind and solar power generated during peaks to be stored, and these surpluses will see a sharp increase as the share of this renewable energy grows. —Professor Buchal.

Generating Power on Earth From the Coldness of Deep Space

Cars That Think

But we have demonstrated that by directly using power generated by the cold universe, we can chill water to cool buildings by as much as 5 ºC during the day without electricity and light the night without wires or batteries. As the technology improves, we see it enabling solar panels that work at night as well as day, powering remote sensors.

Gravity Batteries, Green Hydrogen, and a Thorium Reactor for China

Cars That Think

No battery is perfect, however, so engineers keep pushing for new and improved ways to store those electrons. The gravity batteries described in this story lift giant weights in the air or up mine shafts to store excess electricity, releasing the weights later on to recover the stored energy.
