It is possible, except it is always easier to project forward as if the issues are simple to solve
when technically we are just starting to be able to have driverless lorries and cars.
The cost issues still stand.
Peter now that technology has evolved it will accelerate even faster..
Its now or never mate and cost isnt an issue anymore saving the plannet is...
Money has been created by banks for the last century banks have loaned money to people which creates money that isnt really there.. Its the same for you mate if you take a loan out your borrowing something that isnt yours,,, you then pay intrest and that invisible money that you loaned in the first place now doubles...
Cost should not be an issue here and the goverments of the world could if they wanted to produce more invisable money to do this..
You say that rocket fuel is expensive .. its not really peter its free from our fossle fuel which is still in abundance... it just takes free money to be printed... everything is free its just controled by money..
Ok so lets look at this project in a diffrent sence and forget rocket fuel... how about wirless electrictity ?..
As you know the moon orbits the earth so anything with in range of the moon can also orbit our earth.. so we build wirlesss electricity space stations and put them in orbit.. each one being able to transmit wirless electricity that comes from solar power all the way to the moon... then shuttles lock on to each one in turn and fly to the moon that way... as you know electric cars are now faster than fossle fuel cars so theres a good chance they can make air crafts as fast... we dont need rockets... shuttles can get you to the moon... it will happen and robots will build space stations on the moon one day..
Plant life can provide oxergen on the moon solar power can be used on the moon also... bingo you have giant space stations that can house thousands of people... it could accelerate quite quickly... im going to give you some statistics now..
