I'm going to steal a page from "Mad Engineering" today, and try to think creatively about one of the big problems that's facing Rural AK: Power. Renewables are good, but you still need diesel power for covering all the spots where there's no wind blowing, or sun shining (Yes, Solar Power works in AK). You can't effectively tie villages together in a grid so that wind energy from one village can help a village having a calm day - the cost of running power lines between villages is very high! And the cost of running powerline from the railbelt grid is even bigger.
What could be a steady power-producer for the villages? Orbital Solar. It sounds crazy, but the idea isn't that futuristic - you put a solar array in space where solar power is much more efficient (because we lose a lot of energy to the atmosphere). It's then beamed down to earth as radio or microwaves, where it's collected by antennas. You can position the satellite so it's always in the sun, even at night. Each village would have a microwave dish to collect energy from the power station being beamed to it.
Surely something like this is expensive, but there's a chance you could get a partner to help you develop this - the Military is very interested in the idea because it will allow them to have electrical anywhere in the world, and shipping diesel to Afghanistan might be the only place more expensive than the bush! Collaborating with the Air Force to test-bed this technology would be a great way to bring it to the bush.
So: How crazy does this sound? :)
