Li-ion battery stores a weeks power for a home, from Panasonc Answered

www.popsci.com/science/article/2009-12/panasonic-will-market-li-ion-storage-battery-home-use-2011

As its a breach of copyright to post more than the link to the site, I am just saying that this device is what everybody needs if they want to be independent of electricity suppliers.

You still need a power supply, this would just be storage.

Yes, but today's big problem for Greenies is storage, I got solar to replace some of my low voltage power suplies, for things like PC speakers, I am close to generating wind power, but the problem is, storage is costly.

Currently with solar, due to storage costs, there is only 45 days per year, that I use the system, so its mainly a supply for power cuts, using banks of 36 LED lights

BTW, Wellington NZ, its going to be windy for at least the next 5-6 months, either hot or cold. BUT the last 3 days, was strange, no wind, we had low lying mist all day. The rest of NZ has great weather. They say Wellington is the windiest capital in the world.

Have you (yes you surely have) heard of "flow batteries"?

Please explain

Aspies remember detail of something, but rarely the name of something.

The devices are electrochemical cells, but rather than being self contained units, the two electrolytes are run through the cells between big storage tanks. They can be cheap in terms of energy per unit cost and you can increase storage by making the tanks bigger.

Yes, I always believed something like that to be possible, but on cars, I thought  rather than recharging, you just pumped out the two used tanks, while refilling the two charged tanks.

And its that membrane that is hard to produce. Thanks for the link, its in my temp folder for follow up.

Have you read about the inventor using a wind mill to churn air, to heat it, then ran that air into his house for heating, he got really good output, that surprised him too. Thats in PMM or PSS, 60s to ,80s era.

The wind-device sounds familiar, excepting mechanical losses you can see how the efficiency could be quite high.

Meh, pop sci has been promising the moon for decades. Call me when I can actually buy one.

Very true, Popular Mechanics Magazine is just as bad.

Look at how many cover articles both have had since the '50s, announcing the replacement for gasoline car engines.

BUT, both magazines make money for their shareholders by publishing stories.

BUT in this case, rather than a lone inventor, its Panasonic making the an
announcement VIA PSM.

And if Panasonic disappoints its shareholders?

And such announcements will affect the price of shares for Panasonic on the share market, than there are plenty of legal watchdogs monitoring companies like Panasonic should they try and influence their own share prices with promises they can not keep.
