I am the president of a non profit (501 c 3) organization called Technology for the Poor. I am a retired professor of engineering. I invent, design and promote simple technologies that the poor can fabricate, repair and operate. I travel to Africa, India and other countries working with village technicians and introducing them to Pedal Power, Container Gardening, Low cost house using rice and wheat straw. All these technologies are described in my web site www.technologyforthepoor.com In the US, I set up container gardens that are appropriate for inner city neighborhoods.
