Intercepting KKVs in low Earth obit with a laser: It's got all the right elements: radiators heat up as power increases, the laser itself is invisible but focusing optics do scatter it, targets are conical and gradually vaporize under fire...

The bacterial flagellar motor can spin at 100,000 RPM in one direction, then switch gears and flip to spinning in the other direction. How does this work? Cryo-electron microscopy reveals some of the nanoscale mechanics involved:

The Shuttle Training Aircraft was a Grumman Gulfstream II modified to simulate a gliding Shuttle orbiter: It still needed to drop gear and reverse thrust to match the terrible L/D of the orbiter on descent.

Orion nuclear pulse drives are powerful *despite* their design. The energy efficiency of the 10m diameter USAF design was just 0.78%, as the 1 kT pulse yield converted into 2 MN thrust at 3350s Isp. Animation Brian Mac Mághnais :

On the dark side of the moon, a radio telescope could be suspended over a 5km diameter crater. it'd bypass the ionosphere and be shielded from Earth's electromagnetic noise, achieving substantially greater sensitivity. Real Engineering (Brian Mac Mághnais):

The original 4000t Orion design dropped a nuclear shaped charge every second, averaging 100 TW of thrust power. A single launch of this vehicle would deliver more payload to LEO than the entire Apollo program. Brian Mac Mághnais:
