6 Sci-fi Technologies About to Change the World (part 2)

So last week we had talked about the Space Elevator and the De-extinction process. This time, I am going to introduce the sound waves extinguisher and the air touch technology as I promised. I specific put them in the same article because these two technologies already exist, so my order is from the technologies that may change the world in near future to the ones that are changing our world right now.


3. Sound waves' extinguisher

In 2015, Viet Tran and Seth Robertson, a team of two seniors engineering who majored in the George Mason University shocked the world when they published their self-made inventor. A brand new type of extinguisher which used low frequency sound waves to extinguish the fire.

What Makes It Different From Others Traditional Fire Extinguisher?

We all know how danger it is when it comes to the firefighters to go into a blazing fire and save the victims. What’s worse, there are some kinds of fire that can't be put out with water, for example, some chemicals will react with water and release heat and flames. If someone tries to put out a fire like this with water, it would just increase the fire. So with the sound waves' extinguisher, we can keep firefighters safe when these machines put out a burning building. What’s more, we don’t have to waste a lot of water to extinguish fires anymore! How brilliant!

4. Air Touch Technology (Virtual touch screen)

Virtual touch screen is a dream come true for any technology enthusiasts. I guess it had already appeared in at least a hundred different movies, and now it no longer fictional. Virtual touch screen was originally inspired by holography and after a decade of study, Microsoft finally unveiled an optical head-mounted display utilizing called "the Hololens". Users can display virtual objects through the optical head-mounted onto the visible environment around them.

How It Works?

After put on the optical head-mounted you will see a screen or keyboard floats in mid-air, and when you “touched” the mid-air by your finger, the signal will immediately transmits to the computer or mobile device.

What Is the Advantage and Disadvantage of Using Virtual Touch Screen?

The privacy is guaranteed to have when you're using the air touch technology because nobody can't see your screen or keyboard in the virtual space and the user is the only one who can see it. But although it is really cool and convenience, it is advised that you should use the optical head-mounted indoors only. It is too dangerous to use it while you are walking outdoors because the screen in the mid-air may blocks your view and causes some serious accidents.

I will stop here and continue the topic next week. Next time, I'm going to introduce the Hoverbikes and the Personal Robot. Personally, I love the sound waves extinguisher. I think it may help the firefighters and the rescue workers a lot, otherwise their occupations always put them into an extremely high-risk situations and may die on the job anytime.


P/S : I just found out that Viet Tran, one of the creators of the sound waves extinguisher is a Vietnamese. I feel so proud right now!!!
