News just in from Bloomberg is that Larry Page, of Google fame, is funding not one (Zee.Aero) but two (Kitty Hawk) personalized flying-machine (dare I say flying cars?) startups. With a number of other companies pursuing the same goal, it seems a gold rush of sorts is on. Yet remember the real gold rush? The real benefactors were the pick and shovel makers. The equivalent in this flight to the future are employees with highly prized skills brought to bear on a decidedly tricky problem. And at the sharp end of those with specialized skills are...Computational Fluid Dynamics (CFD) experts - providing valuable insights into aerodynamics, propulsion, batteries, and electrical/electronics cooling.

Yet another way to reveal the hidden secrets of your Computational Fluid Dynamics (CFD) simulation is to create a face, usually a plane and often referred to as a cutting plane, to serve as a target for interpolated results.

I'm sure you realized that the post on Colorful Fluid Dynamic Paint published on April Fools' Day was more than a coincidence. Full confession - Colorful Fluid Dynamic Paint is fake. However, if we ever do get something like it, I'll be first in line to try it!

Forget having a single paint color for your next vehicle purchase and instead go with Colorful Fluid Dynamic paint that changes color according to the airflow around your vehicle. Once only the domain of wind tunnels, pressure sensitive paint and the newly available air speed paint can produce stunning dynamic surface contours as you drive.

While marginal gains are all the rage in cycling, US trucks by comparison are a target rich environment when it comes to external aerodynamics. Specifically the name of the game in haulage is to minimize fuel costs and that translates directly to minimizing drag.
