Doing something important with the time and talent I have left.

I am a strange person. While in a class at University of Wisconsin Madison, I learned about hydralic facturing which was then just starting to be used in the oil industry.
At that time (not sure 1978?) I suggested that sand (rounded sand) should be pumped into the cracks created to keep them open. Now of course we are using that to produce natural gas from formations where otherwise it would be impossible.
Now I want to do something new and build solar updraft slopes.
