Good post.  You're right there are many things go

Good post.  You're right there are many things going on in technology.  There is a process to take hydrogen and make diesel out of it. All kinds of restaurants are now selling their used cooking oil to be made into diesel.  And this company is on the cutting edge. I can't even guess the things we'll see in the next 10 years.  Right now, both solar and wind are not competitive.  But that is just a problem to be solved. We just have to get past stupid things like using corn to make ethanol. It was a stupid decision then and it still is.The world needs that corn for food. Algae, on the other hand, looks real promising.  My best to you,  Jim
