Uses of Bulk Nano Materials (was beanstalks)

(Henry Spencer) :One problem I have with the person claiming that we will not have bulkNanoTube materials is that they seem to think all research is for thier usein beanstalks only. Ofcourse if this was true the amount of money and peopledevoted to the problems would be few indeed.However the uses of such super materials is so wide that tens if not hundredmillions of dollars a year are being spent because of the range of uses. Just about anytime that today is done with fiberglass or carbon firberstructures could be done light and/or lighter with Nano materials. And anumber of projects that today seem to be at the limits or even beyond theability of present day technology become possible (IE a bridge link japan'sislands).There is plain too much money to be made by the successful producter of bulkNano materials to believe that if it can be done that the method needed willbe discovered.

Around 40% efficiency?

I was under the impression that somewhere around 60% was available OTS, with 90% possible with more expensive systems. I could check...

If you get the chance, I'd be curious -- my numbers are somewhat old.

After a quick Google search...

It seems large commercial alkaline hydrolysis units are around 65-70% efficient. Electricity costs seem to be about 70-80% of the hydrogen production cost.

Commercial PEM electrolysers are apparently slightly less efficient at the moment but are promising to soon reach 80-90% at pressures in the

10-50 bar range. PEM fuel cell research has been aiding development.

Norsk Hydro seem to be one of the main leaders in the industry.
