Re: [CGUYS] Better than a UPS
Yet another example of really bad reporting. The only reference it gives is a click through to a Gizmodo story that actually words it MUCH differently. Instead of telling us Panasonic is launching this battery, Gizmodo tells us they are only now launching a joint venture aimed at *developing* a powerful lithium-ion storage battery. The one picture supplied has no size reference in it. The screws make it look smaller than a car battery. But it's hard to believe that thing could run MY refrigerator for a week. And let's not even try to add in the heat pump and space heaters and air conditioner.

First, if home batteries like this one become commonplace, renewable sources of energy like rooftop solar and residential turbines could finally take off. The biggest roadblock to their adoption is that they are intermittent; reliable storage is needed to make them effective. Second, if affordable storage is achieved on the home-level, there might be less need for grid-scale storage, which is pricier and harder to accomplish. * ** List info, subscription management, list rules, archives, privacy ** ** policy, calmness, a member map, and more at http://www.cguys.org/ ** *

It is built into Adobe Reader and hardly anyone uses it let alone knows it is there. This makes pdf files dangerous viral vectors unless you turn off javascript in reader. Your Mac is probably safe since you probably use Preview to read pdfs. The article is an older one from last spring but there have been exploits using a similar technique since.

I also note that Panasonic plans to market the battery in 2011, which of course means that it has to be slightly more than vaporware. http://www.physorg.com/news180778009.html * ** List info, subscription management, list rules, archives, privacy ** ** policy, calmness, a member map, and more at http://www.cguys.org/ ** *

Re: [CGUYS] Better than a UPS
I dunno. Again, we're talking a question of size, and none of these articles can begin to guess. One article used the word massive, but that's probably a guess. Certainly if it's as big as a lithium car battery, you would need a lift to move it around. Actually the Gizmodo article references an article on Physorg.

Re: [CGUYS] Better than a UPS
Battery alone will never work. Just tonight I went outside to take my son to work, and my garden lights were not working. It has been overcast all day long and raining so they did not get a charge. Now I know that the solar panels on them are small and not high quality but extrapolate that out and you see that they need almost daily charging to be totally reliable. Also I am waiting to see how the car batteries last. The older hybrids (Toyota and Honda) should be about reaching their 10 year mark shortly and the cars will need to change out battery packs. I wonder how much that will cost. Stewart At 08:18 PM 1/16/2010, you wrote: I dunno. Again, we're talking a question of size, and none of these articles can begin to guess.

Ah, but this depends on location. If you lived say, in the southwest desert around Las Vegas you probably wouldn't complain. On Sat, Jan 16, 2010 at 9:33 PM, Rev.

Re: [CGUYS] Better than a UPS
True but how many folks (percentage of the population) live in a naturally sunny place? The problem with any one size fits all technology is that it fits some well, and either looks like high water pants and a crop top on others. Multiple ideas need to be developed and used.

Re: [CGUYS] Better than a UPS
So I extrapolate that it will run an average US house for about 6 hours. I'm not sure about real time frames. Japan is fourth on the list of energy usage per individual. From what I can figure, that would allow the typical US household slightly more than six days. * ** List info, subscription management, list rules, archives, privacy ** ** policy, calmness, a member map, and more at http://www.cguys.org/ ** *

Now I know that the solar panels on them are small and not high quality but extrapolate that out and you see that they need almost daily charging to be totally reliable. Garden lights have cheap, usually poorly made, solar cells. If you bought them more than a year or two ago, they have NiCad batteries--cheap ones that are less than 500 milliamps, and low quality. The NiMH batteries in the new ones are cheaper and low quality. If you change the batteries in your garden lights to Duracell/Eveready/Rayovac 2000+ mA your lights will charge better and last longer, even on cloudy days [but the batteries might cost more than the lights. Lithium batteries for heavy use are entirely different from NiCad and NiMH anyway--no comparison. Aside from cell phones and other electronics, they're used in cars and for storing power generated by solar PV shingled roofs. We've been following the development of PV power and storage for over 20 years, but only recently has it become more affordable, thanks in part to the investment by the German government that encourages homeowners to install the solar shingles. Similar projects are in progress in Japan. In the US? For now, open your wallet and pay for it, unless you live in a state that can afford the tax credit. * ** List info, subscription management, list rules, archives, privacy ** ** policy, calmness, a member map, and more at http://www.cguys.org/ ** *
