I see what you did there]]>Apr 25th 2010 2:48AMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/Apr 25th 2010 6:43AMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/Apr 25th 2010 6:44AMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/
Solar powered camcorder? Lol!]]>Apr 25th 2010 2:51AMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/
Only the smart ones will not buy fake stuff. Like me. AND, this is a good invention. And it is you who are slowing the development of technology. There are so many others like you, who I hate so much. So go hug a bear.]]>Apr 25th 2010 3:10AMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/
Well sir you are thinking about this wrong. I agree a stand alone solar charger is much smarter idea but this might come in handy. Think far away from electricity in the forest you put the camera on a motion sensor system and you can take video or photo of animals for months. Doesn't really matter how fast it will charge for this specific application this might actually work. You set the camera up and come back in a month to collect the footage. ]]>Apr 25th 2010 3:26AMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/Apr 25th 2010 6:36AMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/Apr 25th 2010 3:30PMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/
Solar panel charging is fine, but you need a bigass panel and a whole lot of time for something with the powerdraw of a camcorder... cmon.]]>Apr 25th 2010 3:42AMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/Obvious troll is obvious.

As an example, if the solar array is 12V and the cells you are talking about is regular 1.2V AAA cells then the optimal charge time will be only a tenth of what you calculated...]]>Apr 25th 2010 6:46AMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/
So we are left wondering perhaps]]>Apr 25th 2010 6:21AMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/
http://www.greenbatteries.com/bachfa.html#How long to recharge

2500mAh / 120mA x 120% = 25 hours, according to them. ]]>Apr 25th 2010 6:49AMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/
Think of what you wrote about the four AA cells. If you wire them up in series then the whole pack is still the same mAh as before, however the charge time is trivially four times as long given a the same power output from the photo cell]]>Apr 25th 2010 8:43AMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/
And yes, the charge time is indeed four times as long, as stated above.]]>Apr 25th 2010 8:44AMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/Apr 25th 2010 10:22AMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/
The amperage rating is only half of what you need to know to calculate it. Without the voltage rating, it's really not useful.]]>Apr 25th 2010 11:08AMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/Apr 25th 2010 6:06AMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/Apr 25th 2010 9:18AMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/
Why does EVERY single Chinese company that pumps out these sh*tty products use the same god-awful gothic font?]]>Apr 25th 2010 10:51AMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/Apr 25th 2010 11:35AMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/
A rechargeable AAA (as this has, see original site) is about 1Wh, so with 4, this would have 4Wh capacity, so it would take 5 hours of direct sunlight to charge. On a cloudy day it would take 8x as long again (40h), indoors in a bright room it would take about 400h.

And that's if it's a good solar cell (it isn't) at 100% efficiency conversion/charging and the sun is directly overhead all the time.]]>Apr 25th 2010 12:29PMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/
And this is why the only solution for anyone who wants solar-powered gadgets (except 'recharge your gadgets using ordinary power from a wall-socket, some of which could come from large, efficient solar generating stations') is developing gadgets that use less power.

Solar-powered calculators have worked fine for decades (I still have one that's about 20 years old), using tiny solar cells and by definition ancient technology too, and that's because calculators use virtually no power. Unless we can get camcorders to at least approach that level (relative to the appropriate size for a solar cell), which doesn't seem that likely in the foreseeable future, then an in-built solar charger won't make any sense.

They'd probably do better with a wind-up charger; you'd probably have to do an awful lot of winding for one minute of filming but it would look kind of cool! Like old hand-cranked film cameras...]]>Apr 25th 2010 1:50PMhttp://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/http://www.engadget.com/2010/04/25/jetyos-hdv-t900-solar-powered-camcorder-will-capture-only-your/Apr 25th 2010 11:55PM
