If I read the specs on this thing correctly, it will let you run the MT2496 for as long as you have sunlight plus an additional 4 or 5 hours, making it perfect for festival recording among other things:

It even comes with a mini-USB connector, so no hacking required!

Very cool... I am still enjoy the hacking though... I have a JVC digital camera and picked up these 7.2V 3500mAh batteries real cheap for a trip I took over the summer, I don't use them much now... so I wondered how I could use them for running the MT... Energizer makes this universal charger (ENERGIZER ER-CH1 SPEED CHARGER FOR CAMERA BATTERIES) I got it used for a couple bucks, it has various adapters for the different model batteries... they open with 2 screws and have lots of room inside, so I threw this together a few minutes ago...
http://fecundswamp.peanutonastring.com/usb_batt_v5/index.htmlI think this one wins in the power vs weight arena... I had two of these batteries and bought two more for my trip and 1 battery ran my camera with the LCD on for almost 6 hours... I think it would run the MT for a long time.
I only have JVC batteries... there are 3 other 'adapters' that I don't need, if any wants them, message me...
