I would say that on the basic physics, we haven't developed new physics. I would say that the capability to manufacture components using some of the newer technologies allows us to actually put into practice some of the things I've been dreaming about for the last 10 or 15 years. If at a point in time when this 35% better engine is on the table and you were to go and look at it, you would be surprised at how non-spectacular some of these things are.
But that ability to go and manufacture it, the ability to build it as an overall system in a different means and to take the technology we've developed over the last 10 or 15 years from a combustion perspective and from an aerodynamics perspective, that starts to materialize into a product that will be very disruptive for us. As you know, 35% is not a small number, but by the same token I would say that it's the continued and continuous development and the willingness to fail, supported in partnership with the Canadian government, the Quebec government, and the Ontario government, that allow us to go and do that.
Fundamentally, manufacturing technologies like 3-D printing are allowing us to develop some of these things, as are the new materials, lightweight materials, and just the computing power that allows us to go and analyze things to a level that we couldn't have done 15 or 20 years ago. I think there's a convergence that allows us to leverage that.
