Conclusions from The WTC Disaster Printer Friendly Version
During the past several days, I've been seeing those sad scenes from the World Trade Center disaster again and again. Now, I am wondering whether there might be any conclusions to be drawn (and I mean something that goes beyond the killing of more innocent people).
One of the images that struck me most was that of people jumping off the WTC in panic and falling to death. I can't believe that, at the beginning of the 21st century, the only way of escaping from a burning sky scraper is committing suicide by jumping out of the window. If a building is taller than 1000 ft, why don't they have any parachutes for emergency purposes? I don't know if this is technically feasible, but if it's not, there are definitely other solutions. I mean, if you travel on a ship, you expect it to have life-preservers for every passenger. So I think it wouldn't be too much asked to have a similar life saver for tall buildings.
Reward: It would be rewarding for me if others could think about these matters as well and come up with some constructive ideas. (Maybe someone has a new approach to enhance the safety on planes?)

Portable solar umbrella Printer Friendly Version
Having recently spent a bunch of time in some of the world's hottest deserts, I wonder why no one has marketed a portable solar umbrella hooked up to a drinks cooler, or small cooling fan, or one of them electric cooling collar contraptions. Googling for 'solar umbrella' points to large unwieldy umbrellas good for patios and backyards - hardly convenient for hauling around.
Making these should be a no-brainer. You'd have to fix flexible solar panels on top of a folding umbrella, and run a wire through the handle. I bet somebody with a low cost production facility already making umbrellas could easily adopt this and do a pilot batch. You'd start by marketing in the Sky Magazine and the like, hopefully, it catches on to start mass production.
Reward: I'd personally test one of these in the Atacama Desert in Chile next July (a week long 250km ultra run).
