How much ozone would it take to block solar radiation on Mars if chambered in double panned glass or material? Said $O_3$ would break down from the UV. Would applied electricity on $O$ and $O_2$ make $O_3$ again? Glass weighs to much and is not an option unless it is made on Mars. I propose gas because it doesn't brake down like UV film can.
Could a blimp house an entire colony on Mars?
Would a Faraday cage made of gas block radiation?
Can air pressure be accumulated this way for a biodome or spacesuit?
