Would this work/ be practical? *infrared*

I know they make Motorcycle helmets with built in headlamps to see at night, but would the same idea work with IR lights if I coated the Visor like the goggles in this instructable?

No. That instructable is pretty far off the mark. At best, it filters out enough visible light that near infrared that you wouldn't normally notice becomes noticeable. More likely, it just adds enough false color to give a weird look to things, vaguely similar to the way a camera sensor or infrared film would look, maybe. Read the assorted criticism in the comments... In either case, it doesn't do the sort of image intensification that you get with a military style IR viewer; a dark room with infrared light sources would be just as dark (or darker) with the goggles as without. Alas, the mythical 'filter' that you can SEE an IR-only illuminated scene through is fiction, despite its compelling use in Rick Brandt books. Sigh. It takes optics to make an image, and electronics to amplify and shift the image into visibility.
Though there are materials that re-emit infrared in the visible spectrum, I think that's how the monster flashlight worked to get so much out put, the optics were coated with re-emitting materials that emit visible light... That was a garbled sentence but there are such things, though the usefulness is questionable at best for a motorbike helmet, theres a good chance you may miss road signs etc or be unable to see objects that absorb a lot of infrared... Having a camera like the one on the mercedes S-class wouldn't be out of the question though, potentially very useful to see further ahead of your headlights. Having seen them in action a heads up on the inside of the bike's windscreen would be a good option.

I considered a camera, like in a few of the nightvision instructables, except localized and mounted to a helmet. Though I lack the Exp, and materials for such a thing. If I wanted to add a sense of nightvision to my helmet, without having a blinding visable light source, what would you recommend? Something Relatively cheap being the key factor.
If you wanted something to illuminate ahead of you on the road fork mounted lights would be easy and cheap to build, if you were looking specifically for helmet mounted lights it's probably going to have to be visible,light for the win, as a guide I'd say look at the helmet mounted lights here along with the bike lights. The other issue you need to consider is compromising the crash protection of your helmet, putting holes in the structure isn't good but if it has a clip on piece above the visor you could maybe adapt them in to that. For a more costly option you could mod a pair of camera sunglasses in to a helmet and remove the IR filter to create a nightvision helmet using IR leds, granted it might be dangerous or distracting.

Pressing on the Glasses Idea, would a system comprised of helmet mounted B&W "spy cams" (With IR filter removed), portable video glasses, and Helmet mounted IR LEDs at least be plausible ? And I should have made this clear in my post; The helmet is just kind of a concept idea, with the intent of neglecting the Shell integrity of the helmet in general. I got the idea when talking about night time airsofting.
Oh right if it's a prototyping idea then by all means try it out, I think the glasses would provide and effective camera/screen combo, the LED's would be easy to implement, after that stage looking at improvements would be a simple case of trial and error, a few stick pads and some IR throwies could mean high sped testing to get the positions of the LEDs just right, also you could technically use them to see behind you, that would be cool...

You need proper IR goggles to see IR. That ible is tosh.

However, there are systems like this available for aircraft, tanks and civilian cars. I saw a demo on TV years ago of a Mercedes (or BMW?) being driven in total darkness, without the lights on. There were IR headlights beside the normal ones, and a B&W image of the world was projected on a HUD in front of the driver. The vision was better with the HUD than with normal headlights, and when used in fog it was almost as good as daylight (except for being black and white).

I don't know why it hasn't trickled-down to be a standard fitting on high-end cars and an option on mid-range cars. Cost, I expect.

I remember something like that and Jakalope touched on the subject. I think the system would GREATLY Surpass the usefulness of being Car mounted, if it were applied to Higher-End Motorcycles. People are always complaining about the safety issues with night time riding as it is. If a system was available to aid night riders, there might be less controversy. Sure It would probably cost more, but then again, whats the value of human life?
