That's me.

Yes agreed, but the car battery looks better over a 2 year life which may be more realistic for a technology project, also it can be procured locally

I was thinking no server and not much reserve. I understand that a panel feeding directly into the OLPC's DC-DC converter may not start up, that's why I suggested a battery at all.

Can you provide costings for the charger and tech specs?
