i wish i was as smart as you
btw, go ahead and name one thing that is essential that was developed by nasa. not sort-of, kind-of useful, not something that is a convenience, not creature comforts. something essential.
Name anything that has ever been invented that is essential.
To **kind of** answer your question here are a few things NASA came up with that, though not ESSENTIAL for life to on on this planet, either saves lives or makes life safer and easier.
Hydraulic rescue cutters
A rescue tool used by fire departments across America uses battery technology first employed by Nasa. The cutting technology – used to free accident victims from wreckage – employs a miniature version of the power cartridges first used on the Space Shuttle and is 50 per cent lighter (and 70 per cent cheaper) than previous rescue equipment. The cutters work more quickly than conventional ones and were used in the aftermath of the 1995 Oklahoma Federal Building bombing.
Personal storm warning system
The personal lightning detector is popular with boaters, golfers and those flying private planes, but this low-cost spin off was developed using Space Shuttle expertise. After being pointed at a cloud, the device detects the formation of lightning by analysing subtle changes in light level. The invention is now popular around the world.
Baby food
Through Nasa research on algae (which it was hoped could generate oxygen in space through photosynthesis), it was found that certain algae contain two essential fatty acids present in human breast milk. These acids play an key role in infants' mental and visual development. A synthetic ingredient that contains these acids is now added to baby food in 66 countries.
Life support for patients
Project Mercury, the first US human spaceflight programme, which ran from 1959 to 1963, developed sophisticated monitoring systems to track the physiological status of its astronauts. The same technology is used today in intensive care units and specialist heart units.
