ssssshhh!! Don't ruin our nerd glee!Not exactly like a tractor beam, though...based on the description and the photo in the artcile, you need optics on both sides of the object to reflect beams and give you control over how the object moves. We're still working on a repellent force principle here, rather than a true tractor beam, which works on some kind of attractive force principle.
Heh... Whenever I read that word, I think of a beam that turns things into tractors.
What? I'm from the countryside.
ROFL.. I was thinking BEHIND the tractor, as usual (for farming).. now that I think of it, TNG era ships tow/repel from in front when they're trying to keep something away or from escaping... but when they're actually TOWING, then they do actually lug it behind them.best I could do with MS Paint
