Apparently, a couple of chemists in this company were not paying attention in thermodynamics class.<BR/><BR/>I concur with TJ Rodgers - both the government and the VC's have thrown money down a rathole. Interesting that the $30+ million invested in Nantero equates to $0.10 per American - ironically, the technology will prove itself to be not worth a dime.

I...I agree with the notion of the previous comment. If the length of the span that the nanotube is not controlled, then the electrical force required to bend the tube must be varying, which means that the switch voltage must be varying. A random array of nanotubes suggests the beam length is random, which suggests that the switch voltage must be random as well. One could design circuits to get a few bits in a large memory array to work, but it suggests a very low probability of most bits working.<BR/>On the other hand, is standard mechanical models don't work in this region, the above argument is not valid. Of course, if it is valid, then the fix would be to align the nanotubes.<BR/>Perhaps what is most likely is the company is doing nanotube alignment, and not telling anyone. That keeps the competition, like IBM, confused.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5554620.post-1114705459858876012005-04-28T12:24:00.000-04:002005-04-28T12:24:00.000-04:00Hmmmm......sounds interesting.

It would seem important though to have ensure that the distance spanned by the nanotube across the gap be need to be controlled in order for the electromechanical properties to be consistent.<BR/><BR/>This would suggest that alignment is truly needed, if standard mechanical models apply in the nano-realm. It would be interesting to see the data for this.....Anonymousnoreply@blogger.com
