First I live in Omaha nebraska, and the kyak is covered with heavy canvas and sealed with thrift store enamel.

Here is more bike tubing and parts recycled. I've rode this thousands of miles,it's very comfortable and it does'nt make my arms or wrists numb.

Heres the happy face prop again, it worked great, but was heavy,fractured the 5/8 prop shaft, and fell to earth breaking 4 blades.

Here's my version of a sail wing with a streched wire trailing edge.

Here's one with plywood ribs and aluminiun skin.

Here's a younger me flying my new Ritz Standard ultra light.

My wife had to try it.

Here's a flying vw bus.

Here's a 13 x 13 solar collecter, using 1' sq. mirrors. I have melted the solder on tin cans with this.

Some of the mills pictured were never coupled to a generator, but were sure pretty to watch spin. And the Ritz is still unfinished and I am still alive.
