Seems that what's good for laptops is good for flashlights and cars these days.

Hi there,
The way they are talking i hate to see what the price of these
are going to be
Would be nice if they are much more chemically stable though.
Just a little better isnt good enough though as higher capacity
could mean bigger fire.

Any new technology is interesting, but doesn't mean much as bold claims. There is a lot involved in getting a new technology sufficiently researched, tested, produced before even getting into marketing, manufacturing, competitive pricing, deliver on commitments, acceptance by mainstream to the degree that big names are willing to switch over.
It isn't particularly useful to lump lithium batteries into the same category & characterize them as all having a fire/explosive risk. It has them sound ignorant of the newer safe lithium chemistry developments that many big players are producing already.
I think for a new chemistry player to really get noticed enough to break into the established markets, they have to come up with much more energy density and or many new features. Examples are eneloop with first low self discharge NiMH, or A123/Emoli developing safe lithium chemistries with further enhancements underway with electrolyte & anode-beyond current carbon construction....or hydrogen fuel cells.

Hmm according to a picture, 1.6V.
More info would be great though, especially how long they will last. If its only recharges 100 cycles or degrades in 6 months then the applications are more limited. However if they come close to, or even exceed Lithium in details such as this than there could be much more promise. SO many things to consider... temperature range, discharge rate, recharge rate, self discahrge.
Not a lot of info out there on secondary silver zinc cells that I can find.

several years ago they touted batteries for laptops running off of alcohol. Fuel cells and made a big deal about them. I even heard they had tiny engines (generators) in them running off of alcohol making electricity or something like that. Until they get it to market too much technology is only for the James Bond era never to get to the consumer but rather fantasy as far as we are concerned. Any technology that can be patented the royalties will most likely render it too expensive to compete these days.
