It sounds great. There’s only one problem. It doesn’t work:

Despite apparently violating fundamental laws of physics, Steorn planned to demonstrate its machine to the public Wednesday at the Kinetica Museum gallery in London.

Steorn, however, ran into a minor problem — Orbo isn’t working.

Steorn posted a note on its Web site:

“We are experiencing some technical difficulties with the demo unit in London. Our initial assessment indicates that this is probably due to the intense heat from the camera lighting. We have commenced a technical assessment and will provide an update later today.”

Yes, of course. Camera lighting. I’m sure that’s it.
