Re: [Vo]:Recent advances in thermoelectrics...
From: Mark: First, a few excerpts from the article found here: http://www.physorg.com/news/2012-01-quick-cooking-nanomaterials-microwave-tomorrow-air.html It's really amazing as to how nanostructures seasoned with just a few atoms of sulfur can lead to such superior thermoelectric properties of the bulk material made from the nanostructures, and allows us to reap the benefits of nanostructuring on a macroscale, Ramanath said. Interesting article, Mark. I would assume that from an engineering POV this kind of technology could eventually be reversed in order to generate electricity. Perhaps even in an efficient manner as well. Regards Steven Vincent Johnson www.OrionWorks.com www.zazzle.com/orionworks

First, a few excerpts from the article found here: http://www.physorg.com/news/2012-01-quick-cooking-nanomaterials-microwave-to morrow-air.html It's really amazing as to how nanostructures seasoned with just a few atoms of sulfur can lead to such superior thermoelectric properties of the bulk material made from the nanostructures, and allows us to reap the benefits of nanostructuring on a macroscale, Ramanath said. .then. Additionally, the new study shows the Rensselaer research team can make batches of 10 to 15 grams (enough to make several pea-sized pellets) of the doped nanomaterial in two to three minutes with a microwave oven. Larger quantities can be produced using industrial-sized microwaves ovens. And the following point. Those who argue that Rossi's inability to produce/replicate his 30% efficient thermoelectric technology was proof of a scam, have no clue what they are talking about. I have visited the facilities at svtc.com in San Jose, and been involved in some technical discussions about semiconductor wafer fabrication, and I can tell you that it is not uncommon to have difficulty reproducing some performance specs. The excerpt above is an example where a VERY SMALL change in what goes into the process or 'recipe' can make all the difference between success and failure. And it isn't only materials and gases that matter, but temperatures and temperature cycling, and a whole host of other 'process variables'. -Mark

If Rossi had not been scamming, he would have been able to produce at least one sample or maybe a few samples of material yielding 30% efficiency. He could not even provide a sample which worked as well as standard technology. He has not been able to since. If it was not a scam, why would he not have kept trying? Why would he not have *ever* made and shown a single device that met the claims he stated? An efficient TE device would be perfect for producing electricity from E-cat-generated steam. If Rossi knows how to make efficient TE devices, why does he not combine them with the E-cat and close the loop so it runs without external electricity indefinitely until its nuclear fuel runs out? That would be at least months and maybe years, not the silly four hours his typical demos have lasted.
