safety... not sure, but who cares LOL
No kidding - it should be safe enough. It should be like the hydrogen engines for cars (still prototypes too of course) - the hydrogen is sodden in aluminium, so it cannot explode...
One example:
http://www.physorg.com/news98556080.htmlThis article says that it's a new invention, but it is definetly not - I know that such development existed in my country from 10 years and more, however it was never made in real. The problem was that you cannot charge whole car so easy and fast, so the option is when you go to the gas station to replace your aluminium tank with a charged one... trust me it's very heavy and the gas stations do not have enough space to keep them
I never thought that such production can be implemented for phones
