Does this technology gain an increase in efficiency over normal collectors by reducing the start up time for the machine, because you dont need to raise the temperature of the working fluid to just below boiling point before operation starts, so less initial energy input. Or does it come from the temperature of the working fluid being less during operation and not having as large thermal loses? Or is another vital mechanism at work that I have missed?

Its an interesting approach to a 'steam engine', re-utilizing older technology with modern materials & methods for future needs. There are some passionate debates about steam technology; now it seems a classical bottleneck for steam utilization has been bypassed. Sunlight makes a better fuel than petroleum; these green power projects aren't just fashions; its a new principle that requires rethinking systems architecture and more efficient resource utilization. Economics will be the most effective judge on this.

waterhorse2002 SOME ONE (ehm ehm, Bill & Melinda Gates Foundation) needs to FUND a Proof of Concept "Campus" - with test houses & buildings running 100% on this technology with perhaps cellulosic ethanol backup.

I think it still producing little volume of steam which can't be used, so we need a huge concentration solar pannel to boil a usable quantity of water :(

"For the solar steam project, Halas and Neumann set out to design a particle that would interact with the widest possible spectrum of sunlight energy. Their new nanoparticles are activated by both visible sunlight and shorter wavelengths that humans cannot see." That's how they did it. Anyone interested in making one for themselves would have to purchase their nano-particles.. bummer.

The interesting facts are posted ,in several comments ,But to make such Carbon Nano tubes ( from plastics is Not that difficult.There are several Videos that show this technique,using extreme heat and Carbon derived from --Yes Plastics.You can Find this also on KZitem .The Temperatures are about1200c If Memory serves Me,for a short Period of time 30min-1 1/2 hrs,in order to make the Carbon Nano tubes.All you need too do is make an Effiecient Gasifier/Pyrolysis Machine.The rest is Simple Tech.

LOL I'm going through my old youtube likes and saw I liked this video way back when I was applying to college. Rice was my ED, and while I was eventually rejected, I did have the chance to listen to Dr. Halas speak at the Physics Colloquium at my alma mater, Bryn Mawr College. Dr. Halas also happens to be a Masters and PhD physics alumna of Bryn Mawr! I even wrote about it on my college blog: canilang.blogs.brynmawr.edu/2016/09/25/naomi-halas-ma-84-ph-d-87-on-solar-steam-generation/
