worlds most used product!!!!, page-23

less concrete is not a big saving there getting mpa's of over 250 now but at a low cost will the cost of nct be cheaper is the question. It may have many good uses but is it cost efective. To me all it seems good for is maybe nano bots for medical uses atm if it can replace the metals (for the magnetic problems)(personaly I think they are going in the wrong direction as elements only get so small)this is where nano carbon could come in usefull.(no trials with carbon have worked yet tho) I just cant see it been cost efficient now I have looked deeper into it. altho I still don't know the cost of the nct. (if anyone can help)
