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.
