A Marvel of (Intelligent) Design: A Biological Rotary Engine

Could you even imagine a sports car with such a powerful, finely tuned rotary engine, whose rotor, drive shaft, and subunits work together so smoothly, that the engine can hit 42,000 rpm and achieve 100% energy efficiency? Well, no… as amazing as cars are these days, the best redline at 10,000 rpm and achieve below 50 percent energy efficiency, meaning that less than half of the power produced actually propels the car. The rest is emitted as wasted heat.

Millions of Frozen Embryos: An Ethical Blind Spot for Evangelicals
