Yes it is, as with any such endeavor. DM me if you think I might be able to help. I know some people and know of some people in Chicago, NYC maybe MSP. My wife's BFF's husband is in solar advocacy in CHI.
You must be familiar with Will Allen and Growing Power's story. Gotham Greens and their facility on the roof of Method's plant in Pullman, Chicago. Roof Crop will lease your roof space where they will grow crops to sell to local restaurants.
Other sustainability thinkers I follow: Bill McKibben (Deep Economy), David Orr (Earth In Mind), Paul Hawken (The Ecology of Commerce; Drawdown are must reads), Amory Lovins. There is a "climate futurist" on twitter, Alex Steffen, who is always a compelling read.
I'm not sold on tiny houses because it doesn't allow enough density in an urban context and it requires a lot of transportation to amenities in a rural setting - unless you are self-sustaining. I think there is a place for them in a green economy but it shouldn't be too big. It's great to minimize and optimize a single family home, if that's what you absolutely have to have.
I have yet to see much optimism for market scale fusion in the near future, much less "pocket-fusion". People in that space like to say they're perpetually "20 years from scalable fusion". But hey, there's always a chance.
