But, to be honest, beyond colonizing mars, building electric cars, a solar future, and high-speed, vaccuum tunnels, he is missing the one important part of being a motivated industrialist: storing his urine in jars. I mean, the Spruce Goose flew for sure, but let's face it, Howard Hughes wasn't legendary until he started bottling his urine.
Colonizing mars - Not happening in his lifetime. Building electric cars - With other peoples money. A solar future - debatable (see Building electric cars) High Speed vacuum tunnels - Hardly. Legendary for what ?
Memory fault -- brain fried
