You can read more on the PowerPad technology on the <a href="http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=/netahtml/search-bool.html&r=4&f=G&l=50&co1=AND&d=ptxt&s1=electrofuel&OS=electrofuel&RS=electrofuel">patent page</a>. According to the specs, this solution has the Tablet PC running for about 13 hours on a charge, so imagine what such a solution can do for a Pocket PC! Of course, you couldn't fit a battery of the same size in a Pocket PC, but then again the Pocket PC is a lot less power hungry than a Tablet PC. It will be interesting to see when Pocket PCs will start benefiting from new battery technologies like this.

I was a bit disappointed when I heard about the fuel cells and the methanol that is required.

Wouldn't be surprised if this one would require uranium sticks or something like that :lol:

Those batteries have been available for quite a while - the company used to be called ElectroFuel (I think it's a Canadian company) ... they have them for many makes and models. Have one for my Toshiba Laptop and it worked great on overseas flights (>8 hrs life).

On a similar note, the current Toshiba Portege 2010 laptop (ultrathin) comes with an extended battery that I use around the office with WiFi on all day - get about 6 hours from it with a relatively small battery (on with WiFi connectivity). If a laptop can get this kind of time, why cant a PPC get 20 hours? :evil:

I'd love to see PPC battery power take off like this. As it is, I can get a rather impressive 6 hours on my iPaq (with the light off) if I'm listening to music and/or doing standard PIM stuff, but if I'm playing games or watching videos, that battery life goes right out the door.
