Uh...
1: This is a sculpture, not a machine.
2: It explicity isn't more than 100% efficient, and there's no reason to think it could possibly be made so.
3: The person who wrote the article is a moron who doesn't have the most basic grasp of physics.
4: Inarticulate rage at ignorance.
This is an externally-powered sculpture some guy said looks like a perpetual motion machine. Some village idiot interpreted this as a magic infinite-energy machine.
I promise you that whenever people say they have a perpetual energy machine, they are lying. Now, if you want cheap energy for the world, there are several ways to do this that don't rely on blatant violations of physics. For instance, solar or wind are cost-competitive with the cheapest dirty fuel sources. If you insist on a technological miracle, I encourage you too look into Fusion research; our ability to contain and purify plasma grows faster than moore's law would suggest, meaning that we are only a few years from net energy gain.
