A Space Cannon, CERN style!

I know kickstarter has a cannon project but I just had my own thought...

How about a CERN style cannon? A 3 mile oval/circle of tubing, the object goes in, then using a series of blasts or maybe a laser, bring the object to as fast as possible (eg firing a laser into some kind of dish mounted on the payload for space) as it speeds up while tracking it...

The other side of the 3 mile track a hydraulic system to lift a section of the blast tunnel up for a trajectory into space a few moments later the payload arrives and wooosh out into space it goes!

Doing it this way means you can gradually increase the speed (laser, electromagtic acceleration, etc) until the speed needed is approached.

What says you? :)

Particle accelerators are circles because charged particles are easy to send in curved paths using magnets (without actually costing any energy.) Anything you'd want to send into space doesn't have that advantage, and it's very expensive (energy wise) to change the direction, even a little.

See http://www.astronautix.com/lvs/sharp.htm though...

Simple, when the object gets up to speed just open the roof and deploy a deflector plate. Friction on the plate might be an issue but a little grease should fix that.

How about a MAC?

XD XD XD

It would have to be certified space grease though!

Yes it needs CERN (Clearly an Engineer's Ridiculous Nonsense) certification.

A sort of circular high-pressure pump?

With the materials needed, a beanstalk to high orbit might also be possible.
