And yet more air conditioning exacerbates the very problem—climate change—that is driving the need for more air conditioning. The machines are already generating electricity at scores of installations, and the company’s backers include some of the biggest names in tech investing, including Bill Gates and Vinod Khosla. What to do?

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.

Can Flow Batteries Finally Beat Lithium?

Cars That Think

Monique closes her EV’s fueling port and heads onto the highway with enough stored energy to drive 640 kilometers (400 miles). Their energy density is as little as 10 percent that of lithium-ion batteries. To shrink them enough to fit in electric vehicles, you need to raise their energy density to that of lithium-ion batteries.

Up close and personal with Volkswagen’s e-Golf carbon offset project: Garcia River Forest

Green Car Congress

Emission reductions produced by the project are verified by an approved third party and registered with the Climate Action Reserve (Project ID CAR102 ). In addition to the direct benefits of storing carbon, wood products have also been shown to have fewer associated greenhouse gas emissions compared with concrete or steel.

Tech Talk: How sodium-ion batteries could slash the price of EVs | Autocar Professional

Baua Electric

Car technology has never been in such a state of flux as it is now, and given lithium-ion batteries only really became a commercial big deal in the 1990s, the sudden shift towards cars powered by them is extraordinary. Overall, SIBs are around 30% cheaper than lithium ion.
