Define no cable.... I know how to hack it and make it solar powered. Granted it will take a while to charge and I'm not exactly sure how well it will do from overheating (most likely it will)
In all seriousness, buying a new cable isn't hard and changing the screen is easier than you would think.
Now, I'm not saying we're primitive, but we sure as hell don't have anything remotely as good to fix things with, other than a basic set of tools to make ethernet cable ends. That said, I probably could solder a thing or two!
I don't think it'd be that successful here in the UK. I haven't seen the sun in a few days, and we're mostly indoor, so the lumens power isn't that great at all.
