Metal Air Battery 80% Lighter than Tesla’s Model S Battery Bank

Metal air batteries have been around for a while, but they just don’t seem to be taking off in any significant way. Are they suppressed because they work too well?

We don’t know, but with this new Lithium air battery that is only 1/5th the weight of a standard lithium ion battery, you might think so.

Here is a new battery that is literally powered by sweat! With this battery stuck to your arm, it could be charging your phone while you work out, go hiking or do other physical activities.

Sweat-Powered Battery Prototype

The new battery is powered by lactate, which is present in human perspiration. It has a very low output right now and is in the “proof of concept” stage, but they’re working on increasing this.

At the moment the power is not that high – only four microwatts. But we are working on enhancing it so it can power small electronic devices.

Battery Secrets & Battery Rejuvenation

The Battery Secrets and Battery Rejuvenation presentations by Peter Lindemann are the definitive talks on lead acid battery chemistry and how to properly charge and rejuvenate them.

We have proven to be able to recover 80% of the lead acid batteries doomed for the dump AND be able to bring them back to 80% to 110% of the capacity of a new one. That’s right! We can even bring back some old used batteries to better than new condition.

Both presentations are available here:
