BakVac sucks up dust bunnies with fuel cell tech

Here's a design concept for cool-tool vacuum makers to consider: the BakVac. Why drag around all those moving parts when you can wear them on your back like a turtle? Makes sense. Adding to the convenience factor is an electric motor powered by a fuel cell, keeping those pesky electrical cables from tripping you up.This idea might take a while before it's practical, what with fuel cell technology not quite perfected enough to make a household cleaning device cheap enough to compete with all those wild designs available today. But it' a compelling concept: Just pour a little easy-to-get ethanol into the BakVac, and that liquid is turned into hydrogen thorough the magic of chemistry, firing up a fuel cell, no batteries required. Dust bunnies beware.
