Rooftop solar has really taken off here in Australia, and around 20-25% of houses have a solar inverter. Is it practical to build a cheap rooftop wind-power harvester that plugs into the inverter?

Yes, I should have been more specific - I was thinking of something much smaller that could sit along the roof-line of a typical suburban house.

The site supplies separate wind inverters too. I guess that means that the turbines supply very different power to solar panels.

Pay for full time, beat-walking emergency medical technicians in shitty neighborhoods. This would prevent a lot of unneeded hospital visits and offer basic health services. A lot cheaper than 911 calls. I imagine having people on the ground would prevent a lot of problems.

Netflix, but mostly decentralized. End users can be paid to allocate part of their PC's storage toward movies and shows that they stream to their neighbors, taking a lot of the load off the public backbones and central servers.

Of course, these are encrypted and only decrypted (transcrypted?) when they're transferred to someone nearby, intelligently based on `tracepath` or something. My thought (may or may not be feasible) was that the central server only gives you the public key for the data, and then provides the private key and a new public key when the data is transmitted. I'm not sure that's even possible with any level of secrecy, but if so it would remove a lot of redundant traffic and I imagine you could pay people less than you'd save on bandwidth/peering if you could just pay them to P2P content (securely).

Get theaters involved in the initial distribution since they're everywhere and have digital copies (and probably decent pipes).

Basically, my internet got really crappy every day at about 6 PM and I imagined that 90% of my neighbors were streaming the same episodes of Breaking Bad, and it bugged me that it wasn't just sent once and the distributed locally.
