Houses that Rotate to Follow the Sun and Harness its Power

With the Ambanis set to build the world's most expensive new home in India, I can't but think that they have blown an opportunity to save money (yes, they could use that to build more schools - the one that they own is excellent) and to inspire by example. Just check out these designs listed by Tree Hugger: http://www.treehugger.com/files/2008/09/seven-rotating-houses-and-towers.php People are going to flock to look at the proposed 60 storey Ambani home, no doubt. It will become a tourist spot in the future. Wouldn't it have been vastly better if what they saw was something like these homes to inspire the people to, at least, build more environment-friendly homes?

Though South Asian governments like to brag about how advanced they are becoming, they do have a very long way to go. I do wish, though, that someone would do something about building green homes. There is immense potential, my friends. Green energy is as high tech as software and space programs are.
