OOOHH, I get ya, I've always found people using revenue sources from the physical world to generate growth for tokens/blockchains a fascinating thing and quite frankly a nobrainer.
It's such a good idea, Like you say with the solar example. Generate electricity, supply the shop with free energy and then any surplus goes to buying in this case COLT.
Sounds like a sound idea and something that'll be perpetual for many years so long as the hardware holds up.
I'd be all for DHF funds going to fund such projects so long as those in control are reputable, multi-sig accounts help too.
But like you say most either don't want that level of responsibility or are not know/trusted enough for such proposals to pass.
But overall, This is absolutely something more people should try do if they are able to.
Multi sign I think is a must. For me now with the coffee Well most of it should be going to huckleberrie account the delegation account. and a slice to tommys.shop. but I think right now all should just go to small for delegation to get it started and bulk to hucklenerrie to get those funds up.
I can see this working within all levels of society. but should work as a non profit too. Benefits or profits should be directed toward consolidating what we have or things like human resources a better water system education research independent housing Each generation can build on it.
I might beover reaching in thinking it can develop to a decentralised finance monitored and controlled by polls that determine where the funding goes. This also has some levels to it.
For bigger amounts of funding development of a multi layer multi sign might be needed.
