Sending ice into space

The key to cheap space is to get ice into orbit. Start with making steam in the middle if the ocean and sending it up a pipe to where it condenses. Next to the pipe, have a track for containers plus a power line system and solar. 

At the point of condensation, make lox and hydrogen chilled for loaded containers of ice and propellant and load it into a magnetic catapult, launching it toward a depot in orbit for processing for more fuel and for orbital good production.
