The idea is to plug up a mercurian(martian gravity) crater with glass so it can be air filled etc...
My result is
1- it's possible to use the energy of the sun to grow plants etc...
2- the weight of the crater top can be perfectly balanced from the air pressure...
3- It's possible to use water in the crater top to protect the crater from the wrong radiations...
Is it a good idea?...![]()
