Hydrogen and electric cars

b) has a condensation point is so low that the coldness of the liquid state effects the mollecular structure of most metals (steel for example becomes much more fragile and prone to torsion and shear)

and

c) takes an incredivble ammount of energy to get it to the liquify

this seems more than a little unlikely - I know its theoretically possible as described in the wiki entry here but the phase change state engine is just using nitrogen as a very inefficient energy storage mechanism, not as an actual fuel source and it seems very unlikely that even that would ever be comercially viable

Really?? AS your already using the internet please just search the term liquid nitrogen vehicle or car or whatever you want to be fair. As for your comments regarding depleting resources, metals and materials your opinion is not worthwhile evidence is it...

I would ask you to produce documents and reports that were unbiased etc that suggested the actual amounts left, where they are etc.

Practice what you preach.

On a BBC horizon episode there was a small piece on some kind of facility that is currently achieving in tiny amounts and researching changing resources. I think it's called something like Nuclear transmutation or has very similar properties.

You seem wholly incapable of reasoned debate yet come one here with some incredible claims.

The tone of your last PM to me was quite startling.

Marketing graduate you may be but me thinks a little growing up may be in order

I thought he'd gone - I'd come out from behind the settee!

Wouldn't worry about little Matthew Jim. That naive he thinks that someone with the title Surgical Vessel Sealing Specialist can't possibly be in Marketing.

already done that (unlike you i do the research before posting rather than afterwards or not at all) , and as i said i'm aware of the theoretical applications of a phase change state engine , however this is distinctly lacking in comercial viability, and also is an inefficient energy storage device not an actual fuel source

leaving aside the irony that when i suggested you did that you the all your teddies out of your cot and got the thread closed

Copper = 61 years at current usage levels ( there is more copper than that in the earths crust but much of it is inaccesible)

My time is to valuable to be botherred spoon feeding you the rest , but I'd suggest google and the search terms "remaining deposits of .... and " annual usage of .... "

so bright that hes working on the earth shaking application of using QR codes to link print and web media in marketting (something the rest of the world has been doing for years )

nuclear tranmutation is the process by which elements (mainly metals) can be transformed into heavier elements through neutron/proton bombardment in a fission reactor - a laymans explanation can be found here Nuclear transmutation - Wikipedia, the free encyclopedia

its basically useful for processing spent nuclear fuel into less radiotoxic isotopes - it is in no way useful for creating copper , both because it would have to start with a lighter element of the same family (which are in shorter supply than copper), and because of the energy needed to create the ammount required

Interesting conclusion - with analytical skills like that you can see why he went into marketting
