Can we produce large scale electric power using bulk of C N tubes on exciting by means of solar power?

This technology is indeed great and historic in this century. What harm does it cost to the environment. Are we going to plant algae in mass production.

The findings of this project have been of great importance to our mankind. However I want to know which specific grade of CNT was used in the experiment. Can anyone suggest me where I can get the info?

I take it this is conversion of thermal energy phonons) to electrical energy (collective electrons) in nanotubes. The article wasn’t very specific. Thus, the first commentator, Jos Conil, is probably correct in asking if solar energy could excite the electrons in nanotubes. I need to read the Nature Materials article.

How very interesting. By your description it seems like the magnetic fields of the nanotube and the traveling electrons are interacting resulting on energy being released. How long to be ready for practical massive application. If there can be a combination of technologies as suggested by Jos, then there can be applied to every single household and even vehicular.

The process of creating electron motion and thereby electricity by producing heat waves inside a carbon nanotube is an exciting possibility for a large number of applications.

There is one point which I’d like to ask the researchers – is it possible to use this technology for large scale power production from solar power?
What I mean to say is that suppose, instead of the reactive fuel coating which is ignited to cause the heat wave,(as mentioned in the article) why can’t concentrated solar power by means of sun tracking heliostats be used to provide heat waves inside these nano tubes to produce electricity?

Or can igniting bio -mass derived from waste be not used to produce the necessary heat?
