Cars That Think

Electronically-assisted-astronomy photographs captured with my rig: the moon [top], the sun [middle], and the Orion Nebula [bottom] David Schneider First, I purchased a used Canon T6 DSLR on eBay.

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. In this way, sand enables solar power to keep people warm, even during the darkest and coldest Finnish nights. Eronen says, laughing.

Cars That Think

As countries transition away from fossil fuels to green sources of energy like wind and solar, there will be natural lulls in energy production due to weather conditions. Energy consumption also tends to peak during early evening hours , which is inconveniently right when solar energy output decreases.
