Shooting from the hip here.. Folks who live in cold climates and have the know how are the best folks to bring this to the people. I see a Rocket Heater booth at Christmas Fairs, Tool shows, Building industry conferences.. Someone with freedom to be a professional cheerleader, by freedom I'm referring to someone retired from the daily grind with an income unconnected to rocket heating tech. I remember seeing a portable demo heater here on Permies.. we need MORE of those.. all over the country.
Second flash.. a team of permies elves build warm public benches in NYC.. BOSTON COMMONS, CHICAGO, SEATTLE, DETROIT, BUFFALO, CLEAVLAND. In the cold cities, go to city hall meetings and ask to do a permanent public installations. Obviously it's imperative it be accompanied by a perfectly artful bronze plaque explaining the technology (the magical guts) a real blueprint in bronze. Imagine bus stations with RMH benches, cafés with comfy outdoor seating... etc
Getting RMH into public spaces is the key.
Another! Extremely high quality stencils of a RMH blueprint, large and legible. I'm suggesting guerrilla, information sharing, street art. I'd absolutely buy a well-made jumbo stencil. I already buy them every few months for my artwork and jobs. The biggest ones sell for about 70 bucks. That would take someone who would want to figure out how to manufacture quality stencils, or finding a company who does custom work. Screen printing is also good for some surfaces. I have done screen printing on regular painted sheet rock with great results. So let's say I have one of these.. I will go to a local Cafe and ask to do an art installation that teaches people about RMH, talk to science teachers at school, health food stores, feed stores.. adding additional art with the blueprint would be fantastic, that can also be a series of coordinating stencils. This sort of sharing would require a talented artist willing to create the base images for free.
A fundraiser in your local area could fund the public projects.. perhaps working with food bank volunteers could help connect with agencies that give aid to the elderly and other community members who care about promoting low cost solutions to help people maintain general health and well being.
I'd throw in my $25 bucks to a fundraiser to build more portable RMH to take to trade shows (and the likes) or any other permanent public installation someone might take on.
