If I look carefully at what you write, that you are interested in projects that really care about natural resources and save energy, like Pylon. I think there are many projects that also have the same concept as you wrote, but this project is not very enthusiastic and is not going well.
Hey bud, you haven't researched lately it seems.
Already being used at 4 Muncipalities in Spain. And are receiving great response. For eg:-
Our most recent satisfied customer, the municipality of Canet d’En Berenguer from the Valencian community in Spain, managed to reduce their administrative annual electricity cost by 12%, allowing them to create an energy efficiency fund for the local community (with the achieved savings). The news made it to several Spanish media outlets and can be found here.

These guys have started getting new projects regularly and will soon expand to USA.
