It's an Aperture Science Excursion Funnel. Not using the proper title could get you sued or referred to the Aperture Science Non-Cooperative Testing Program. – Shadur Jun 18 '11 at 10:20
It's also referred to as "Tractor beams", That's why Wheathly mentions the word "beam". – Pieter888 Jun 20 '11 at 10:56
