There are hyper-big issues: - in Space micrometeorites and mere high energy received from the Sun deteriorate anything quickly OR it's not much a matter of launching something but keep it operational changing a piece at a time; - it does not scale AT ALL because even at very low price of anything the cost is so extreme that we need something so cheap like "hey this WE instead of a trip nearby I go for an orbital trip, the price is roughly the same"; - microwaves transmission will probably be very harmful for human, nature in general and a big potential danger is a beam move/is traversed by accident. The general real issue we have with renewables is: - they are intermittent, our needs does not match, storage is needed to combine supply and demand but effective storage ON SCALE is missed and not foreseeable in a near future [1] - anything must be designed to handle and profit of peak productions, the very opposite of ANYTHING we have built so far, from grids built at a certain size and interconnection to average the load as maximum to mere water heaters designed to run few minutes per hours instead of hyper-full-power for few hours per day - we are still in a linear supply chain model, p.v. panels and lithium storage recycling is THEORETICALLY described but nothing exists on scale so far and probably will not appear in a short period of time Just as an example my home-made p.v. plant cost around the price of mid-range "cheap" ICE car for around 10 years of expected life (sure modules last longer, but when lithium is depleted and inverters start to age there is no sense in keep old modules, the cheapest part, anymore), even with it I'm far from being autonomous, o sure, FORMALLY I can produce 120/130% of my overall consumption (except the new EV) BUT practically I can reach 50% self-consumption. And that's a new, well insulated home, with various stuff to maximize self-consumption since exactly NOTHING exists on sale with such target, even devices who claim to be designed for that. And the home is in the France south alps so in a very good location for p.v., many live far northern. My conclusion so far is: it's ok-ish to push the accelerator on renewables to improve them since PUBLIC research in the modern financial-driven society lacks, but we are FAR, FAR, FAR behind what managers think we are or at least can be. To avoid hyper-big disasters we have just nuclear, fossil while we create new NPP, nation-wide plan to rebuild homes etc. Something THEORETICALLY doable in no less than half a century. In practice probably few centuries. I'm not joking. Those unconvinced: try yourself and see results. Mine say what I said above. [1] effective means 6 month storage for a country of any size on it's own land, because yes energy is serious and we can't risk more than that at such a scale.
