[andrew] sent us this proof of concept. Based off of the Spiech Clear view screen, used in marine applications, it uses a spinning disk to keep a part of your vision free of water droplets. While you may not be too impressed by watching the video initially, keep in mind that this was a quick prototype. With some planning and a little work, this could be moved to a more convenient location and run by a side mounted motor. It could even be made to be removable for fair weather. It probably doesn’t do so well with mud though.

Please be kind and respectful to help make the comments section excellent. (Comment Policy)
A full-face slipstream-driven version of this was being advertised in motorcycle magazines perhaps 25 years ago now (alongside cigar-like plastic tube thingies that allowed a rider to smoke while riding).
Never seen one for real; perhaps gyroscopic forces were a problem with the larger disk?
this method was also applied to circular wing mirrors keeping them free from rain drops.
Died out due to style and heaters being installed in the mirror.
The key problem with the disc really is its shape it doesn’t really lend itself well to most windscreen applications.
but could be intergrated into large windscreens.
I think a wiper is best!
But its a great proof of concept!
already exists in non motorised version:

my brother used one for his gokart competitions
Very cool, I like the passive one v posted, but $50 is a bit much!
A low resistance bearing and it should be able to spin just fine with some fins.
I wonder if this is legal on a car?
From the video, it seems that a quick application of RainX would have much more of an effect. Doesn’t waste any battery juice, either :)
I had a rotating visor in the sixties, it was driven by small turbine blades cast into the periphery of the disk. It was very effective.
I think a small high pressure air pump would work. I usually just turn my head to clear my visor if I am riding in the rain. Ofcourse if you aren’t going fast enough it does absolutely nothing.
Turning your head does work… for almost a whole second if it’s really raining.
Besides, it’s not really the rain that’s causing the real problem for me, it’s the spray from other cars and especially trucks, because the drops are much smaller.
How about a clear plastic cylinder that rotates around your helmet? You’ll look like a retard, but it just might work.
Is there any way to accomplish this via electro-staic repulsion?
I’m imagining a helmet visor with a thin conductive layer on it, hooked up to a power supply. As a motorcycle engine is just a power-plant after all, so you should be able to run as many volts as you need.
If its raining that bad you need to STOP driving. I know this comment does not help the project or anything but wet roads + motorcycle = wheelchair. It happens all too often.
@sparky – Love it! A sort of transparent Ned Kelly helmet driven by a Savonious rotor on top.
@pragma – theoretically; but the concept of trying to charge myself up to a zillion volts in the streaming rain, sitting on a petrol tank, well …
The other aspect is that this is also used in spray painting and powder coating to get even cover all over, so you may actually *attract* the raindrops. Ooops. ROFLMAO.
Seriously: I think the disk would be more effective (and look less stupid).
I used to work at the same place as Andrew! Small world. Anyways, it’s a great idea. Here in Vancouver, we need advanced rain-shedding equipment!
On my motorcycle I just tilt my head, but I’m now going to make a pair of powered goggles for riding my bike. I hate the goggle fog and this thing should block rain, shed drops and have enough air circulation to avoid fogging.
Working on it right now, and I’ve now built about the same thing as Andrew (looks like we both found the same sized plastic scrap, heh. I need now one big enough to cover both eyes.)
The concept model works remarkably well at staying drop-free. I’m amazed this idea isn’t everywhere!
this is 100% useless why is this on hackaday like for example i have a dirt bike keyword dirt this is fucking useless in mud and when you dirt bike where are you in the f/u/c/k/i/n mud god damn morons like would it hurt to come up with something that’s actually useful really i said this before there’s a reason why you lame fags got hacked like why should we come to you guys for hacked when you got hacked hard you fags are so 1337 really we all know that you are a bunch of lamers trying to capitalize on the community LAMERZ
you guys got no respect from the community you know that right?
as for mud complaints. If you have a clean source of clear water sprayed onto the spinning disk-mud combo, it think it would wash off. Like the windsheild sprayer on your car.
These existed in the 1960s… the strain of trying to resist the torque at speed render many riders almost immobile…
