Could electric fans like the ones below lift a rocket? What is the amount of electricity needed to lift a interplanetary rocket?
Could a nuclear power plant provide enough electricity?

I added the pictures and link to show people who are not familiar with electric propellers and impellers an idea of what is available. I do wonder if these types of engines have enough thrust to vertically lift anything?
Which propelling device would be the most efficient for a space elevator?
