Well there are a lot of high profile vested interests in oil, not least the dollar. Not everyone has an interest in progress.

bit of info about difference between capacitors and batteries.

http://batteryuniversity.com/learn/article/whats_the_role_of_the_supercapacitor

Interesting article. It mentions Graphene Electrodes being 15 years away, but the original article was published 7 years ago so perhaps Fischer's patent will see their forecast correct.

Regarding storage, battery technology is almost 370 years old (although it may be even older, as an urn, uncovered in Baghdad, may have been an early battery. Discovered in the 1930s, the urn dated back to sometime between 250 B.C. and A.D. 250. The artefact contained a copper pipe with an iron rod in its centre - which could have served as the battery's electrodes - and had an asphalt cork at the top. Still inside the urn was the residue of an acidic liquid that could possibly have provided the electrolyte element). It is about time science came up with a better way of storing electricity!

And talking of subsidies. I see the oil industry have their hands out hoping for tax changes in this week's budget, to help them out.

Yes, it occurred to me after I posted that the USA is where it is all happening at the moment and they are certainly not short of sunshine. Probably a dash of contrarian thinking. The principle of energy storage is a given but is existing battery technology barking up the wrong tree? No problems with the electric motor but it seems there are considerable physical hurdles to clear and I wonder whether there will be a rethink on how to actually store/generate/access/convert energy into electricity.

The US also has huge areas with abundant solar energy. They are already building PV installations on the roofs of supermarkets, warehouses and malls. Walmart is self sufficient in energy, in some areas.
Capacitors do lose there charge over time (as do batteries), but this is dependant on construction and type. I have worked with huge capacitors that kept their charge as long as batteries. And as for the amount of energy they can store, that can be enormous. Again it just depends on size how they are configured. Some hypermilers are already using super capacitors instead of batteries.
And we are talking about entire new technology with Graphene super capacitors, so who knows how good they may end up.

Seems to me it is all about energy storage. Currently, this is not commercially viable on a large scale. Crack that nut and we literally jump to a new dimension. But I suspect 'the crack' will be more the result of a slow process of cumulative R&D. Solve that one and the implications are immense as solar energy can then be converted, bottled, stored and distributed. Meanwhile, the EV early adopters are financing R&D.

The early EV adopters are being somewhat subsdised by taxpayer and electricity users as a whole.

Attached PDF is a photo I took yesterday of gridwatch dashboard,  if you hover mouse over the meter it brings up the label shown.  What it is saying is that the solar that is deployed in UK at present is making little or no difference to demand at midday (when solar is strongest and you would expect it to replace demand on other sources of electricity, at least for a few hours ) they are seeing no such so evidence - they admit the figure for solar they show on their meter is being  'generous',  and figure shown was just above 3%. 

There is an installed solar PV capacity in UK (as of May 2017) of 12,318 megawatt,  yesterday panels were supposedly generating about 1.4GW,  which as the site states  is an 'overestimate' as they are not seeing any such affect from solar on the grid to lessen demand from other sources.

Yes to subsidies, as with windpower and most forms of 'green' energy. Nice ideas but not really very viable in the UK.

On the solar energy, I was thinking more specifically about countries with abundant sunshine. So, all those useless deserts will suddenly have a commercial use, politics and big money permitting. Somewhat ironic that the oil producers in the middle east for instance could be ushering out the old and ushering in the new. However, terrorism is probably a big problem. Don't think it takes too much effort to blow up acres of solar panels and I think terrorism in its many guises is here to stay. Find a way through that minefield and the technological pitfalls and it seems to me there is huge harvesting potential but the middle east is not the only place blessed with plenty of sunshine. There are miles and miles of 'outback' in Australia which, as things stand, is largely the preserve of wildlife and a few natives and they are reasonably stable apart from when it comes to the Ashes.
