Thermodynamics FAIL

Claiming to have invented a perpetual motion machine in 2006, Steorn Inc. (previously on Metafilter here and here) challenged a team of 22 international scientists and engineers to "verify" their apparently impossible device. Last week the scientific jury announced their results: “The unanimous verdict of the jury is that Steorn’s attempts to demonstrate the claim have not shown the production of energy,” it stated. “The jury is therefore ceasing work.” But have no fear, fellow citizens. Steorn has fixed the "key technical problems" which kept the device from working, and now plan to commercially launch their perpetual motion device towards the end of 2009. Perhaps more interesting than the repeated failure of impossible physics is the question of whether or not Sean McCarthy and the several dozen engineers that he employs are scammers or perhaps just delusional. A long postmodern treatise on Steorn, the Orbo and the Steorn Forums here.

Next up, the Perpetual Motion Machine

Last week, Genepax Co demonstrated a car that it says runs on water. Video of the demonstration is here. The claim is not without its detractors, and Genepax has not yet released any information about how the system works; most of their website (beyond press releases and general information) seems to be under construction

A history of perpetual motion machines

The Museum of Unworkable Devices, (posted previously) contains an excellent link to a history of perpetual motion machines.

First Law of Thermodynamics Repealed?

Perpetual-motion machine being sold on eBay. It's essentially six automotive alternators connected (via motorcycle chain) to an electric motor. One of the alternators supposedly powers the motor, leaving the remaining five to provide 700W of free energy. Sigh...people actually believe this crapola?

Inventor Claims Zero Point Energy Source Calling his invention a "Jasker", an Irish Electrical Engineer (who is keeping his identity a secret), claims to have a working prototype of a machine that is capable of replenishing its own energy source. We've heard this sort of thing before, and there are hundreds of other "inventors" making the same sorts of claims, but could this one be for real? And how does this fit in with the First Law of Thermodynamics?
