How do you spend your time when you have downtime at work, with nothing to do?

Interesting, I wish I were in your shoes. Since I am almost five decades old, I dream about building that power plant that catches the heat of the sun and converts it into mechanical power and electricity. I can not get over the possibility of building hundreds and even thousands of these power plants across the globe. These will give electricity for lights and appliances and even mechanical drive for water pumps and aircon and refrigeration compressors. its on Electratherm.com also on NYSE listing, They call it "Green Machine"and sells about USD2,000 per KW of capacity. It seems a 50KW plant will cost about USD100T, but it will deliver pollution-free and renewable energy. I hope I can get more people interested in this. What do you think?
