But, as far as I remember, major contributor to carbon emissions are not poor villages, but jet sets and their factories in poor villages exploiting the work of poor villagers who have no say about their air quality lest they lose their jobs like they lost their means to sustain themselves from farming. Indeed, just not flying for fun and not selling the oil and coal that do not really belong to them would be so much more technological than trying to get grants for things they do not understand (and waste them traveling the world on planes telling everyone they should invest in it too only to then burn the rest in taxes used to support oilgascoal industry directly or not). When you show perpetum mobile here it is totally relevant - that's how greenwashing works in terms of economy on every level, no matter what technology is being praised.
