This is a view of the underside of a typical Sky Home. Note the 2 powerful rocket engines used to maintain them in fixed position above the ground. These thrusters, built by North American Gee Whiz, a division of Linda Latte Enterprises, are powered by clean solar energy, and employ a hydrodynamic photon transducer for excellent stability. Not to worry, your Margarita will not be shaken or stirred by these thrusters.
