Who Knows.Probobly "IF you have to Ask you cannot Afford it" :-)

Here is a blip out of the Jan 2002 Popular Science Magazine about a Fuel
Cell Power System that Coleman put on the Market. It had a fuel cost of
about $10 per Hour.


*****
If all goes according to plan, Coleman Powermate will introduce the
world's first practical home fuel cell this month. But don't look for it
at Home Depot: It'll only be available at www.colemanpowermate.com.

The AirGen Fuel Cell Generator is conceived as a backup generator, but
at $7,995 the only buyers will be those who really need a secondary
power source, perhaps for medical reasons. The 1.2-kilowatt unit could
power a computer, phone, fax, and light for 8 to 10 hours before
refueling. And since the only byproduct is water, it can be safely
positioned indoors, unlike traditional generators.

Like all fuel cells, AirGen generates electricity from the chemical
interaction between oxygen from the air and hydrogen. While much fuel
cell development has focused on stripping hydrogen from natural gas or
propane, AirGen requires pure, bottled hydrogen. It took Coleman two
years to create a distribution system and to satisfy regulators (a
Department of Transportation ruling was imminent at press time), but the
company is confident a $100 refill could be delivered anywhere in the
United States within two days.

JE>TW>MR "Know it ALL(AT least according to ONE here) ran across an Interesting

JE>TW>Development. Battery EXPERTS(NOT ME) say they are nearing the limit on

JE>TW>The summatio nof hte Article was that Fuel Cells are the Future of Laptop
