I fancy a visit there too Philip.
They have a lot of marine radio equipment, too.
Plus all the engines &c. should make for a very good day out.

Yes, but what sort of battery could produce 240v at, say, 20 amps for more than a minute? And without getting so hot my house would catch fire. Even without trying to get to the house next door.
I appreciate there's tradeable theories and money to be made/invested etc. But what about the battery?
Genuine question, I'm really interested.

Don't think of it in terms of single batteries, think of a massive virtualised battery made up of thousands of individual units co-operating together, each one delivering a small current for a short time, but together adding up to a significant amount.

The technology is in early proof of concept stage at domestic levels, and of course depends on some pretty fancy software in the Smart meters, but companies like Flexitricity and Limejump are already offering services like this with business customers, acting as aggregators to put together workable demand response units spread over multiple sites and installations.

For every 'skeptical' commentator out on the internet, there are hundreds of extremely bright young people working within the industry to turn the possibilities into working solutions. They even let old farts like me get involved, which is nice.

There's an awful lot of investment going on here, with big challenges and potential rewards. The goal is to avoid situations like last September, when although National Grid managed to avoid any outages we were seeing System prices hitting £1500/MWh for odd half-hours when the background wholesale price was £55/MWh.

MB UK quote 183g/km and 35mpg, combined. About 27 in the real world. Needs 98 Octane though....
£225 road tax for a pre April 2017 registration.
(Tarka is £505.....)

report today thatb sales of diesel cars in the UK are down by over 10% so that probably accounts for the offers being made.

We have battery back-up for our solar panels which is supposed to save money in the evening when the sun goes down. Only had them for 3 months, so hard to tell the difference but time will tell. £4600 for installation which included another inverter.

What is the claim for the output? What will it produce in volts and amps?

I don't know what Bob's got installed, but a Tesla Powerwall packs have a capacity of 13.5KWh with a steady delivery ability of 5Kw.

So at 240v this means a current delivery of just over 20A, but of course this would only last a couple of hours. For a 'normal' household you would normally expect sufficient power to run your house for the evening - assuming you had sufficient panel capacity to fully charge it during the day, of course.

This is what a colleague of mine in Germany has just installed in his new build home. It looks like a very large water cylinder and is about 5 feet high. It hums like a good un ! There must be some big rectification going on somewhere within it.

He had a grant from the local government (Munich) to pay a good chunk of it. I tease him that no one needs to charge the iPad that quickly and he is once again over-egging it.

Apparently it can get enough from the solar panels on his roof to equal out his home for the day. This is calculated using local geographic sun information to provide the panel size needed.

Must be a hell of an iPad.

Wow - early adopter there Bob - considering a retro fit to my solar panels at some point, but thinking price of batteries will come way down when masss production kicks in like it did for solar panels.
