This looks interesting: Prieto Battery working on 1,000x more powerful lithium-ion battery
Hope it turns from vapour-ware to something real.

This looks like some very interesting research, and is in a direction which is likely to bear fruit. Nano technology is about physics, but here we see an example of it being used in conjunction with chemistry, to vastly increase the surface area of chemical interaction, within the same physical space . Although they are aiming for a one thousand fold improvement, if they are only 10 % successful, it is still a game changer .In fact 2% would make a big difference.
When flecc says that he wont hold his breath, he may be right, or at least partly right, in that you will not be able to buy one tomorrow. Even with the very best discoveries, there is always an interminable wait before it hits the market. The other thing that I have noticed is this. Once we have a basic idea working, for example the radio valve [ thermionic vacuum tube] it is improved , one small step at a time. Then its function is taken over by something completely different, in this case the transistor. I think it will be the same with batteries. Horse drawn vehicles saw centuries of improvement before the coming of the motor vehicle.

The inherent problem as I see it is one that has already been experienced, that of the difficulty of getting high currents out of high density content. At low discharge rates this could be very successful and realise most of it's potential, giving a battery with a single charge lasting for many months or even years. I'd love that in mobile phones, netbooks and portable AV products.
Getting high rate discharges from compact extremely high density sources is a different matter though, something that has cost Toshiba a small fortune in unproductive research over a number of years.
There may be an analogy with biology here.
The human body has billions of cells, individually they don't do much but together, loads!
I see this going in the same direction as the Stanford Nanowire battery created in 2007 10x the power
of the existing Li-ion batteries and was expected to be in full production by 2010-2011, but alas the
patent was aquired by a large oil concern. and all further research is now funded by said oil Co

If there was any justice in the world, then it would be illegal to buy patents in order to just sit on them .Power corrupts, and absolute power corrupts absolutely.
I've never bought this conspiracy theory. Oil companies are as concerned as any other companies to have a future and business is about profit, not product. It matters not to them what makes the profit and any company is only too happy to have two sources, in this case both fossil fuel and batteries.I see this going in the same direction as the Stanford Nanowire battery created in 2007 10x the power

If that research was any good, we'd have that battery and the fact we haven't merely shows it's yet another unsubstantiated scientific prospect claim.
And which "oil concern" was this which supposedly bought the patent?
I do not really wish to discuss oil conspiracies. Let me just say this. If you owned a slice of the richest and most powerful industry on the planet, how would you feel if some jumped-up backstreet erk threatened to cripple your business? You would probably be willing to pay .0001`% of your vast fortune to arrange for him to disappear.

Oil companies often seek to protect their business interests, even to the extent of funding groups that deny climate change as, of course, controlling climate change means moving to a low carbon economy.

Flecc, my last post was simply to show that I believed that corruption in large corporations was widespread and that oil companies were unlikely to be the exception. I find it strange that you have such faith in Stanford University, and yet you dismiss the Massachusets Institute of Technology [MIT] out of hand.
I didn't say anything of the sort, merely remarked they weren't a "jumped up back street erk", quoting from your post. I'm sure they are as capable of self interest as any other university.
As you read in that biased article, they intended to use the NiMh batteries themselves, but the simple fact is that they proved unsuitable for automotive use. Quite independently of the American industry, Peugeot in France showed as much with the eventual failure years ago of their widely marketed NiMh electric model 205. In every form of chemistry and construction including that proposal, NiMh cells have not been capable of accepting a sufficient number of charges before the capacity decline becomes unacceptable. That's why the alternative battery technologies have virtually wiped out NiMh now.
To further display my ignorance; I would appreciate an explanation regarding the advantage, if any, of 36v over 24v for Pedelecs.
A second concern for me is the availability of repairs and spare parts; is anyone aware a of a knowledgeable and trustworthy person or company in Essex/east London?
My experience todate is of retail outlets who do not want to share information and technical detail but rather offer a vague promise of support.

In theory a 24 volt system can give the same power as a 36 volt one, but to do so requires thicker coil and supply wiring with higher currents, meaning more weight and heat. So in practice, 36 volt systems are the more powerful ones, the most capable e-bikes all being the higher voltages.
I don't know your area well enough so will leave others to give that dealer advice.

Going back to radical battery R and D. Just imagine that you were the inventor of a brilliant battery, with a very high power density, that never needed charging. Most likely your first thought, if you could afford it , would be to patent it. Now in the USA, and almost certainly in the UK, and most other countries, patents are screened. If your patent is thought to be of value to the Military, or MI5, the Government will seize it. You will be forbidden to discuss it or work on it. The only reward you will get is that if you are lucky, you get to live.
If you were the chief Patent Examiner, you would be failing in your patriotic duty if you did not seize this. Imagine the advantage to the military of UAVs that could stay in the air 24/7, and with stealth technology could overfly any place on earth.The only way you would not seize it, is if the military had something better already. But you would have to seize it anyway, because you could not allow it to fall into the hands of any potential enemy. This is not a conspiracy theory, this is fact . Comments invited.

Easy to answer, it's not actually possible in patent law to suppress the information. Recently in 2011 President Obama passed the Leahy-Smith America Invents Act into law which brings the USA finally into line with the rest of the world's patent law. It's effect to complete that comes into force in 2013 with the "first to file" measure. The effects of modern international patent law, including that change, make it advantageous to publically inform before patenting, putting the information into the public domain without compromising the chance of being beaten to the patent post.
Prior to this, other modern changes also provided further protections. For example, it became no longer possible to patent an idea, one had to provide a construction or detailed method and patent that, not the original idea or eureka thought. It later also became necessary for the patent to describe the way of bypassing it for that way to be barred to anyone else. If the patent doesn't describe a "get around" method, it can be used.
All of these changes have been designed to stop suppression of information, prevent monopoly situations and encourage every opportunity for progress.
Historically there have been abuses of former patent law, in particular by the US federal government and notoriously by a few commercial organisations, chiefly RCA (Radio Corporation of America, later MCA, Media Corporation of America). But as I've described above, the opportunities to do that and in relation to patent law behave in anti-social, anti-progress and anti-American ways have been severely curtailed.
