Re: Aliens
After all, what could we really discover that we could put to good use here on Planet Earth??
As with sex, its not so much the destination, it's the journey that is important!
So too with space travel. The technology required to get out there is massive and has widespread applications back here on earth. NASA claims at least 1650 spin-offs from their space research into our everyday life. Things like:
Light-emitting diodes (LEDs)
Infrared ear thermometers
Ventricular assist devices
Artificial limbs
Aircraft anti-icing systems
Improved radial tires
Chemical detection systems
Video enhancing and analysis systems
Fire-resistant reinforcement
Firefighting equipment
Temper foam
Enriched baby food
Portable cordless vacuums
Freeze drying
Water purification - sweat and urine to drinkable water
Solar energy - single crystal solar power cells
Pollution remediation
Structural analysis software
Remotely controlled ovens
Powdered lubricants
Improved mine safety - ultrasonic bolt elongation monitor
Food safety - HACCP guidelines
