It was definitely worth the price of admission, but I didn’t enjoy it enough to finish. The time loop mechanic just got annoying for me after a while. Having to time lots of different things and if you mess up you have to wait 15 minutes to try again.
That is already a thing and it’s called concentrated solar power. Basically aim a shit load of mirrors at a target to heat it, run some working fluid through the target and use that to make steam to turn a turbine. There are a few power plants that use it but in general it has been more finicky and disruptive to the local environment than traditional PV panels would be.
