[Lex Computer & Tech Group/LCTG] Math’s Block-Stacking Problem Has a Preposterous Solution | Scientific American

[Larry Wittig]

The Blackbird is not that hard to understand. When starting the drag, the
wind makes it move in the direction of the wind. As the Blackbird gets
closer to the wind speed, its momentum keeps it going. Then it makes a
transition where the energy from the ducted fan harvest enough energy to
drive the wheels and propel the vehicle into the wind.  It may
The Dutch (mostly universities) make small vehicles that they race into the
wind -- I think from a standing start.
