Just watched this tonight. What I thought was funny was the guy sitting there with his legal pad of calculations then they get the rear sprocket wrong and the bike wouldn't run.
Best part of these types of shows is how they make something supposedly "green" but it relies on un-green support. Oh sure they could power a compressor off of solar or wind but they probably wouldn't and I wonder what would happen if they took that compressor trailer down for a MOT test and had it's emissions checked.
