I'm interested.
Here's an idea: it would be great if we could design something that could be used for shelter after disasters, such as we've recently seen in the Phillipines and elsewhere.
Perhaps something pre-fab-like that could be easily put together for a small family to live in for a (hopefully) limited amount of time, that would get them out of the weather. These could be manufactured and stockpiled so that they could be ready to ship to where ever needed after a disaster, and possibly packaged with some dried/canned food and a small stove and minimal kitchen supplies (ie. can opener, pot, silverware, etc.).
Once we have a design maybe some of us could get together or a week or two and build a prototype or two. Then organizations like the Red Cross and/or FEMA might be interested in our design. I find it hard to believe nobody has thought of this or done it before...
Anyway, it could our contribution to the non-TTT world. What do you think?
