5 NASA Inventions That Are Now Everyday Household Items

Today on the blog we're featuring a guest post kindly provided by James Hall.  James is a cracking UK writer who is a home appliance enthusiast - take it away James!


5 NASA Inventions That Are Now Everyday Household Items

Ever since I first watched Star Trek as a child, I’ve always been interested in space-age technology. Ideas such as faster-than-light travel or realistic virtual realities still fascinate me – even though I understand little of the science behind them!

In comparison to sci-fi technology, it’s sometimes easy to forget how astonishing “everyday” items actually are. Society has developed so rapidly over the last 100-150 years that we quickly become indifferent to technological breakthroughs – even when they come as a direct result of space research.
With that in mind, here are five everyday items that were first developed by NASA.




 1. Scratch-Proof Glasses

As you can imagine, it’s important for an astronaut’s visor not to get scratched. That’s why NASA scientists in the 1970s put a lot of time into developing strong plastics coated with a thin film to prevent scratching. The result was visors that were up to ten times less likely to scratch than previous versions.

Fast forward a decade, and sunglass manufacturer Foster-Grant realised the same technology could be used on their products. The company was the first to licence it from NASA, although today most plastic lenses have a similar coating.




2. Memory Foam Mattresses

Walk into any mattress shop and you’ll almost certainly be greeted be a sales person extolling the virtues of memory foam. This type of foam, which contours to your body to provide extra support while sleeping, has become popular in recent years.

What many people don’t know is that memory foam was first developed by NASA as a way to protect passengers during a crash. It’s still used for that today, but is also found in pillows, mattresses and even roller coasters due to its ability to absorb energy.



3. Water Filters

One of the challenges of long-term space missions, such as establishing a base on the Moon, is producing clean water. That’s why NASA has been collaborating with a number of companies to develop water filtration systems. The first filters were designed in the 1970s and could handle basic cleaning. In recent years, new filters are being created to convert water with greater contamination – including human urine – into a drinkable form.

While this technology might not be found in the average western home, it has the potential to make a big difference in poorer countries where clean water is scarce.





4. Handheld Cordless Vacuums

An example of a more mundane NASA technology is the humble handheld vacuum. Before the Apollo mission, NASA commissioned Black & Decker to produce a drill to collect samples from the moon. This needed a highly optimised motor and tiny power consumption, as energy would be at a premium during the mission.

Later on, the same technology would be used to create the Dustbuster range of vacuums. Black & Decker still produce Dustbusters today, although handheld vacuums are now built by a wide range of companies.




5. Cochlear Implants

In the 1970s, analog hearing aids simply magnified sound. This meant any noise or imperfections would also be amplified.

At the time, NASA was putting a lot of research time into sound and electronic sensing. An engineer named Adam Kissiah, who also had hearing difficulties, realised this technology could be used to produce an implant that would transmit sound digitally.

He founded a private company to develop a working prototype of the cochlear implant. Since then, hundreds of thousands of people have had their hearing restored – including people who have been deaf since birth.

Getting my eyes tested

Before I get into today's essay, thank you very much to Lauren of Mummy is a Gadget Geek who mentioned this blog in her list of five blogs for your inner geek at www.tots100.co.uk!

Okay, so I wear glasses.

And have been known to sleep under a pink girly duvet.

It's been about two and half years since I had my eyes tested, which is overly long - I know that I should get them done every two years, but for one reason or another (which is another way of saying I'm lazy) I hadn't got round to it.  Anyway, I bit the bullet and booked myself into an opticians last week.

Just one thing that I want to ask: hasn't anyone discovered a better way of testing for glaucoma than the puffy machine yet?

If you've never had your eyes tested, you may not have encountered this, but basically the very first thing that they do when testing your eyes is blast sudden puffs of air into each eye to... well I don't know why they do it, it's something to do with glaucoma (which is a bad thing I think?) but the problem is that the more they do it, the more uncomfortable your eye gets, and the more your body thinks "Hey, if only we had some kind of cover that would protect the eye... oh wait! We've got an eyelid!  Brilliant! Let's close that bad boy!" and before you know it you're having to prise your eye open with your fingers with a faint hope that this time the machine will get whatever information it wants and stop with the puffs of air.

Anyway, I had the tests, I have new glasses (which are extremely light compared to my old ones) and it's all good.

I'll finish off my asking you this question...

DO YOU KNOW WHERE YOUR TEDDY BEAR IS?

If not, watch this video now.  Scary things are happening to our teddy bears.
