Personally, I think fuel cells are the pipe dream that has derailed sensible discussion into alternative fuels.

And I don't care about big business providing the power I'd just prefer we move from sources of power that destroy the environment by design to a source of power that only does significant damage to the environment by accident.

There's a guy in New Jersey that uses solar power to provide all of the electricity he needs for his home. He then uses the excess solar power for electrolysis to power fuel cells that run his home and car through the long winter when sunshine is rare and its energy reduced. To store enough hydrogen to power his fuel cells for 3 1/2 months required 10 1,000 gallon tanks. Fortunately he has 12 acres of land on which to put all of these solar panels and gas tanks.

In most urban and suburban areas this simply wouldn't work without massive infrastructural redesigns. For example, in my apartment complex the buildings and landscaping have been designed to minimize solar exposure so as to minimize the need to use air conditioning during the hot summers. The roofs are pretty steeply sloped so that at any time less than half has sun exposure. The property is dotted with tall leafy trees that further block the sun. To get much use out of solar panels all of the buildings would have to be reroofed and a lot of trees would have to be cut down.

Yes, fuel cell technology will probably become more efficient but we're orders of magnitude away from where the average person in any but the most perpetually sunny environments can easily become completely self sufficient as an energy producer. Nor would most be willing to take the time and trouble of installation and maintenance (solar panels require constant cleaning and large gas tanks exist in a rather onerous regulatory environment).

Asking everybody to become responsible for producing their own electricity is kind of like asking everybody to grow their own corn. It may be a good idea in principle but it simply isn't going to happen. Better then, in my opinion, to focus on converting the existing electrical grid into something that isn't designed to pump tons of particulate into the air every day.

That's not to say I don't support individual use of solar energy and fuel cells. I just don't seem them as a panacea to the structural problems in our we actually supply electricty.
