Visiting the Windshear website, I couldn't help but be taken aback by the shear numbers of that contraption;
- A 6.71 m fan blowing 1345 m^3/sec through a 3.0 by 5.5 m nozzle up to 80 m/s (290 km/h)!
- A 4 MW motor, which will send an electricity bill of 96 MWh (some 10 kEUR) per day if used at full song around the clock.
Knowing just how much time the big-dogs spends in the windtunnel, good mother of Jesus what a waste of energy!
When a 60% model would be happy with a nozzle one third of the above area and probably half the air-speed,
power should be a fraction, why I understand the incentives behind the 2009/10 regulations on windtunnels.

between the last race of 2009 and January 1st, 2010?

So that’s one example where compromise has been found, between the FOTA teams, where the large groups have accepted compromise in the interest of the smaller groups. Now, as a smaller group, I can’t ask Toyota to come down completely to my level but I know that there’s a smaller difference there between what we can afford to do in the wind tunnel and what they can afford to do. So there has been incredible movement within FOTA. I mentioned the cost of engines; these are all FOTA initiatives, they’re all things that the teams themselves have worked together to…. The testing agreement is a totally voluntary agreement between the teams. It wasn’t an initiative started by the FIA, it was an initiative started by the teams. We all agreed to it and to my knowledge nobody has ever breached the testing agreement, and that’s purely voluntary.
