mobile solar power for Sandy victims

"Greenpeace has had Rolling Sunlight set up since last Wednesday night, many days before the Red Cross or FEMA were on the scene. They've been able to get five solid days/nights of power, with one shorter night due to a particularly cloudy day. For such occasions they do have traditional generators they can use.
It's great to see some outside-the-box thinking applied to emergency relief. This is the only solar truck Greenpeace has in the United States, though, and it's only able to power one aid station. So, if you've been cooking up some sort of slick alternative energy generator, you have thousands of people eagerly hoping to be your first beta testers."

    This is interesting in many ways. How many such mobile solar systems would be needed to bring the bare minimum of electricity back to a storm ravaged location?  hospitals, people relying on medical equipment to stay alive, running refigerators to keep important supplies and foods from spoiling. This could be a money and life saver in the long run.  Did the Red Cross or FEMA bring this?  Nope.  Greenpeace.
