Instead of expensive batteries, Hydrostor bets on giant underwater balloons. Technological advances in the field of energy storage have been quite slow, especially compared to what has happened in terms of improving energy generation technologies. Batteries have been accused to slow down the transition from fossil fuels […]

Unfortunately, while new solar cells, wind turbine designs, and biofuel-producing technologies keep bombarding us, the same cannot be said about energy storage. Since improvements in battery technologies seem to be emerging very slowly, any new alternative invention […]

Pretty much anything that stores energy can be used to propel a vehicle, whether as chemical energy in a combustible fuel, electrochemical energy stored in a battery pack, or air stored under pressure. There have been a […]

People have been traditionally using batteries and flywheels for that purpose, but their uses are limited and the energy they can provide (at least in the battery’s case) costs pretty much. SustainX, a company specialized in compressed air energy storage (CAES), has […]

They're the company who designed an engine powered completely by compressed air a few years ago. It looks like they gathered funding from a Tata Motors venture and are now developing a new and more efficient vehicle: the AirPod.

The first time we wrote about these inventions was about 6 months ago. Now, MDI and Angelo DiPietro have contracts all over the world with auto makers to sell them the compressed air technology so automakers do what they do best: cars.

Now they did it. OneCAT is a five-seat car, with a fiberglass body, weighting about 350kg and costing about… 4800$! And that’s cheaper than any car (maybe except the recent car from […]
