‘Revolutionary’ eavesdropping technology patent to help governments monitor Internet chats @ Kurzweilai.net …assuming it ever was, VOIP privacy is now gone.

Rice unveils super-efficient solar-energy technology @ Kurzweilai.net Rice University “scientists have unveiled a revolutionary new technology that uses silicon dioxide/gold nanoshells and N115 carbon nanoparticles to convert solar energy directly into steam. The technology has an overall energy efficiency of 24 percent. Photovoltaic solar panels, by comparison, typically have an overall energy efficiency around 15 percent.” Among renewable energies, solar is the one with the most potential for improvement and provide some sort of “bridge” to overcome the coming “Peak Oil” crisis. Most likely it will not be enough though.
