A lighthouse uses the same lens, just with the light coming from the inside. Since this is old knowledge, what is the drawback? Why isn’t this widespread?
My completely uninformed guess:
-
The lens and assembly costs too much compared to just more solar panels
-
The lens/panel combo is so bulky/prone to failure it becomes unreasonable to actually install/use.
The main goal is to stop people from dying with hopes of making the stopping of the dying permanent. Considering Russia wants all of Ukraine and Ukraine obviously doesn’t want to be taken over by Russia, there isn’t much middle ground to build upon a ceasefire.
The best way to ensure peace is to give Ukraine the tools they need to repel the invader. Secondary tariffs on anyone helping Russia is certainly helpful in repelling the invader.
