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. The apparent contradictions do not end there.

BNEF report finds hydrogen promising decarbonization pathway, but carbon prices and emissions policies required

Green Car Congress

In the years ahead, it will be possible to produce it at low cost using wind and solar power, to store it underground for months, and then to pipe it on-demand to power everything from ships to steel mills. Note: Clean hydrogen refers to both renewable and low-carbon hydrogen (from fossil-fuels with CCS). MMBtu) in 2050.

New nanolithia cathodes may address technical drawbacks of Li-air batteries; scalable, cheap and safer Li-air battery system

Green Car Congress

The researchers refer to these particles as nanolithia. Because these “solid oxygen” cathodes are much lighter than conventional lithium-ion battery cathodes, the new design could store as much as double the amount of energy for a given cathode weight, the team says.

Harvard team demonstrates new metal-free organic–inorganic aqueous flow battery; potential breakthrough for low-cost grid-scale storage

Green Car Congress

AQDSH 2 refers to the reduced form of AQDS. Quinones are naturally abundant, inexpensive, small organic molecules, and similar to molecules that store energy in plants and animals. Flow batteries store energy in chemical fluids contained in external tanks, as with fuel cells, instead of within the battery container itself.

Razor E100 review: A great electric scooter for kids

Green Authority

You can, however, buy these add-ons for relatively cheap. However, you can pick up those parts at your local hardware store or on amazon for relatively cheap. See the image below for reference. Maybe Razor thought the motor was loud enough to replace a horn? You get a handbrake that can stop at a moment’s notice.

Jülich, ORNL researchers advance high energy density iron-air batteries

Green Car Congress

In addition, their main constituent—iron—is an abundant and therefore cheap material. The oxygen required for the reaction can be drawn from the surrounding air so that it does not need to be stored in the battery. In this process, the iron oxidizes almost exactly as it would during the rusting process.

U.N. Kills Any Plans to Use Mercury as a Rocket Propellant

Cars That Think

Bender is referring to the 2013 Minamata Convention on Mercury , a U.N. It’s also liquid at room temperature, making it efficient to store and use. And it’s cheap—there’s not a lot of competition with anyone looking to buy mercury.
