Nano aluminium alloy offers fuel cells on demand
– just add water

The new alloy, which the team is in the process of patenting, is made of a dense powder of micron-scale grains of aluminum and one or more other metals arranged in a particular nanostructure. Adding water to the mix produces aluminium oxide or hydroxide and hydrogen – lots of it. “Ours does it to nearly 100 per cent efficiency in less than 3 minutes,” says team leader Scott Grendahl. Moreover, the new material offers at least an order of magnitude more energy than lithium batteries of the same weight. And unlike batteries, it can remain stable and ready for use indefinitely.
Note: fuel cells convert hydrogen to electricity very effectively. Full cells can be small and very powerful. NASA has been using them for decades. The problem is the hydrogen supply.
This fixes that.
wow!
I am not very technical, does it mean it could replace normal batteries and rechargeable ones?
That would be very interesting and we wouldn't have all the waste of those.
I hope they can bring it to the market for an affordable price.
You would still have a risk I guess that if they leak you would be exposed to aluminum which is pretty toxic ?
nope...aluminium is not the least bit toxic.
That' s great then, thanks for answering :)
Have a nice day !
Sounds like a promising concept.
