Seeing what happens if you give a water propellor a water repellent coating

Seeing if it goes faster or slower.

Seeing if it makes more or less bubbles.

And more.

Update: The water repellent coating should be extremely durable.

Seeing what happens if you give the outside of a small unmanned submarine or a big and real submarine a water repellent coating

Seeing if it will go faster.

The coating should be very strong and very durable.

Maybe through wall imaging.
-Without using dangerous types of radiation.

Maybe with sound

Creating echolocation for humans

1 (training) While blindfolded.
-Having a person at a fixed distance make noise at a random fixed distance with an object or a speaker. The person then has to point towards that person.
-Having a person at changing distances make noice at random spots with an object or a speaker. The person then has to point towards that person. 
-Having a person walk around and and having the person point at him by the noise of his steps.
-Having small speakers all around a person  and having the person point at a speaker that made the noise. The speakers should also be above him etc.

2
- First making noise with the fingers, mouth or with a speaker, without something around. And then going close to a wall and making the noise. And hearing the difference.
-Same as the above but try with metalic and wooden barriers etc.
-Blindfolded go closer to a wall while making the noise and detect when the wall is close, going from wall to wall.

Warning: Safety is of some importance, don't fall etc.

Finding out how you can train your eyes or make your eyes see infrared light naturally

Possible method:
-Indirect exposure, so you point infrared light somewhere and you just watch for hours.
 -Warning: The exposure shouldn't be damaging to the eyes.
 -Wearing goggles that block all light except for infrared light.
-Eating certain foods that are high in vitamin A2. Maybe a certain diet to that.

Fungus resistant matrasses

Choosing the right material. And the material around the matras should also be fungus resistant.

The whole matras should be fully fungus resistant.

Much more durable. Will last much longer then a normal matres.

Putting a metal inside liquid nitrogen and then seeing what happens if you take out the metal and heat it extremely fast

Step 1 Putting a metal into liquid nitrogen.
Step 2 Taking the metal out of the liquid nitrogen.
Step 3 Very fastly put a gas flame torch on it or pour lava over it.

Extra: Trying it with Tungsten and the alloy called tantalum carbide.

Only for people who are walking. Not for cyclists or drivers.

Better filters for coal power plants if possible and if better to reduce smog and harmful air

Cleaner coal technology

Better filters are needed. 

Another idea: With a waterpipe design a lot of fine dust might be catched by the water. If possible. And if this is better.

By Jeffrey Koelewijn
From South-Holland

Update: For the water pipe design: Maybe with ''bubble breakers'', with this a lot more will be catched. Or with extra filters inside the water. And research first if the passing of the smoke and everything with it through te water can give health problems.
And research how useful and effective it is to use this system.

Update: A problem: How to get all the smoke through the water if filtering with water is beneficial. Will it go through the water ?

Update: Offcourse not a single coal power plant would be even better.
