Israeli tech start-up Phinergy has produced a car that runs on metal, air and water. The technology significantly increases the driving range of current electric vehicles and should be in high demand when it hits the marketplace.
Phinergy is a leading developer of breakthrough, zero emission, high energy density systems based on metal air energy technologies, mainly Aluminum-Air and Zinc-Air. Unlike conventional batteries that carry oxygen, these batteries freely breathe oxygen from the ambient air to release the energy contained in metals.
In the video,anyone can see the car in action, driving over 300 km. in one drive. Just refill the water and you’re good for another few hundred km.
Metal-air technology has been at the forefront of energy research for years, due to its enormous energy potential.
Phinergy's technological breakthroughs allow it to efficiently utilize this potential for various applications, outperforming conventional batteries. A conventional battery consists of an anode and a cathode, where the cathode takes up to 70% of the battery’s weight. The cathode is used as a container for a reactant (e.g. Oxygen), usually up to 5% of its weight, that is required for releasing the energy in a metal anode. The result is that most of a conventional battery’s weight is poorly utilized.
A metal-air battery features an air-electrode that breathes oxygen from ambient air, instead of the conventional cathode. That is, the battery consumes the required oxygen from the air, rather than having heavy materials that bound oxygen inside it. Metal-air batteries therefore have a huge potential for delivering high capacity with low weight.
