Man this is a really complicated exercise. Light but strong, cost effective, easy to mass produce, rolls easy. For such a simple machine it's an enormous task.

Ernie,
Yes, it is a real problem to solve all this.
The biggest problem I am facing right now is we are working on housing for Haiti and I haven't had time to really sit down and solve the wheelchair problem.
I have been working with my brother in law to make affordable housing in Haiti and other disaster areas. When we saw the tent cities in Haiti, we knew the real humanitarian disaster was going to be when the hurricane season arrived and devastated the people without shelter. We knew there had to be a better way. My brother in law figured out how to use his concrete panels to make a home that is hurricane and earthquake certified. It is really quite incredible what he has done. I have worked with him for the past couple of months on the metal engineering and design of the structure. We make the metal parts in our shop. Here you can see Brian and I lifting one of his light weight concrete panels.

We load a container with the first of the homes this week for the doctor in this video. When we get back from Haiti I will focus back on the wheelchairs.
