Wind powered vehicle speeds much faster than wind; downwind!

Anyone who'd done any Iceboating knows you can get over 3 times windspeed on a reach but downwind? I didn't believe it until I saw it; pretty impressive:

A Long, Strange Trip Downwind Faster Than the Wind | Autopia | Wired.com

They are shooting for 3+ times windspeed, directly downwind. Watch the 3 minute video to see it go and the 7 minute video interview of the inventor ............... it's pretty cool.
