Engage The Tractor Beam!!
Star Trek fans rejoice. A small scale demonstration moved a particle toward the tractor beam when two scientists focused a pair of Bessel beams at it. I'm already in over my head, so don't look for any further explanation here. But I can post a great graphic.
Large scale tractor beams of this type would probably destroy the object trying to be moved. Here's the link to the abstract at phys.org:

Once a large scale tractor beam has been developed, what would you use it to do?
My first use would be to draw the moon closer, just to see if what "Bruce Almighty" predicted would happen.
Or to move the refrigerator to me, instead of me having to walk to it.

True, but the problem is that they are always thinking about something else instead!

This is more a solar sail than a tractor beam. http://en.wikipedia.org/wiki/Solar_sail
A true tractor beam would use gravity waves.

Yea, but the dipsticks keep spending money on learning things like why frogs are green instead of how to create/capture/control gravatrons.
