You don't belive that do you Julez?

All the folks I know in the biz say this is far, far off. I tend to agree given it will most certainly be seen in military applications years before commercial ones...

Another thing to remember when you read about some research lab developing a new battery (or any other) technology or improvement. They develop something new. Then they have to find investment capital to develop it to be a practical marketable item. They may already have invested millions or tens of millions in developing a prototype display unit, something in small numbers that shows that something MIGHT be practical for a company that wants to take a chance on developing it into a practical and especially comercially salable product. In case you haven't noticed, many companies in this country won't spend a whole lot of development money, especially if it's for something "Not Invented Here!" in their own labs. And don't pay attention to the claims of how many Trillions are spent on devlopment here. Aggregate numbers are pretty meaningless. That's not only here in the US, but many other countries as well. Bringing a new technology to market can be EXPENSIVE! and TIME CONSUMING. Even the company I worked for for 28 years often considered Engineering and Product Development as a loss or cost center, not a profit center. Often bean counters seem to wish we'd have just dissappeared. And I used to work for a large American based international corporation that was praised (and villified!) for having one of the highest rates of investment activity in this country - 5.5 CENTS per dollar of sales. That, compared to a German book publisher that was considered to be a miserly investor in technology at 8.0 cents per dollarof sales. But, technology investment takes time to recoup, and that kind of heavy investment reduces money available for executive bonusses and maybe for the companies that still pay them, stock dividends. Heck, I even remember seeing us loose a great opportunity to tripple our market penetration in one product area just by repackaging an already developed and high selling high profit product "Because the company would have to add 3 resources!" (one electronics engineer, one technician, and a drafter). Gotta love the intelligence and forsite of MBAs (IMHO, that means Minimized Brain Activity!)

Remember this next time you see a big article about how some University or private research lab has developed a "Startling New Technology!" Until it actually gets on the market, it might as well be science fiction, like Warp Drive or the Star Trek Transporter.

I remember when I was very young in the UK and building and flying Keil Kraft kits which cost me - I think 9d (ninepence) - and consisted of a few sheets of printed balsa which one cut out with a knife, a little bundle of longerons, some tissue, a length of rubber, some pre-bent wire undercarriage, a bit of transparent plastic for the cockpit, a propellor and its mounting, some wheels and a tube of glue - I built hundreds of them!

Anyway - what I meant to say was - I remember being given an electric plane which had a battery consisting of a little sack thing into which one poured a little salt water. I think I am right in this, a very long time ago, but it was electric. The plane flew free-flight for maybe fifteen seconds and that was that!

Sigh - such nostalgia.

I got 9d a week pocket money which just covered one plane every three weeks, the fourth week being for dope.

Each plane flew maybe once.

Looks like they're curently interested in an automotive application. Lets see, over 4 V/cell? 3 for a sandard car starting battery. How many cells for an electric or hybrid?

I wonder how long before they branch out into other consummer related sizes that'd be practical for our use. The package they are showing is .38" thick, 3.82" wide, and 7.48" long. Weighs 12.87 ounces. Bit heavy. Maybe for boats?
Still, always good to see new development coming along.

And here's the latest one:

http://phys.org/news/2013-01-yolk-sh...d-battery.html

This looks very promising, will it disappear in the vastness of the deep dark Forest of all the past breakthroughs. .....Likely... however i'd like to keep the candle burning.

(Mods can this thread be stickied ?) This Thread is far from over.
