>From my "Prius technical Stuff" list - imagine the run time of a laptop using one of these "batteries"

Better still, imagine the run-time of a MAINFRAME using this as a power source...

Hi,

When looking for a high energy density battery, I've long known metal-air was the way to go. It looks like the Japanese have made impressive progress:

Energy densities like this make electric aircraft possible.

[TE] note the comments at the end - someone pointed out that a roughly 50-pound battery would power a Tesla roadster for a year before needing a recharge...  (the current tesla pack is something on the order of 600 pounds - I don't know whether or not the commenter took into consideration that 550+ pounds of battery are no longer being carried around...)
