How is it a joke?
I fail to see how harnessing a natural resource is a joke.
Cost per watt is far too high using the methods he is purporting to use. It may never pay for itself due to long term maintenance costs as well. This is not free electricity.
All I am saying is there are better, more efficient ways to harness wind, and Sun. There are also other methods to generate power that are viable which he is not even talking about.
There is a lot involved in doing something like this right. His is more of a lip service approach, but I guess it is something. I just do not see it working for the long term.
As a matter of fact, he is probably going to do more harm than good for the long term if he stays the course he is laying out.
