- Vertical farming in skyscrapers, growing our food where we live in a closed system allowing maximum growth from minimal resources all while being organic.
- Clean power, or maybe a better way to store/transport already existing clean power. This could be significantly better batteries, fusion power, neutrino based wireless power, who knows I'm just making stuff up know.
- Cars that drive themselves.
I should have known that Google would be the one to save the day. Apparently they've already driven 140,000 miles in an automatically driven car in the San Francisco Bay area. I'm excited about this, and can't wait for it to be mainstream. Hopefully it won't take long.
