Clothing that produces electricity.

Perhaps if bike clothing were made out of this, we could re-charge our lights, etc. as we rode.

Ya know? Trend Micro (PC-cillin) just gave me a warning about that site? Anyone else getting a blip from it?

Ummm ... no. They are definitely still being made, and are widely used among randonneurs, 24-hour racers, and other ultra-distance cyclists. I got mine in the summer of 2006.

I think you need to take a look at Peter White's site.

Aw crap someone shrunk my nano shirt. Now I need to find another $10000 for a new one. Or....I could just buy a dynohub (shimano is even cheaper than schmidt for those of you who are not flush or dedicated enough to the schmidt investment).
Seems to me nano wires would not be that sturdy. I'd also be surprised if this ever even produced more energy than a blinking LED. There is no free ride in the world of energy, you are not going to get more energy out of that shirt than what your movement or wind put into it, ie you might have enough to light an led or run a really efficient mp3 player but that is probably it. Personally I would not fork out the big money for something like that when a solution like the dynohubs produced power much more efficiently.

An acquaintance who has one told me that he got his used as "they don't make these any more". Perhaps he meant the particular model or he had.

Which one does he have? They still make plenty of them. I have a Shimano N30...which is no longer made, because it was superseded by the NX-30. I can still buy Sturmey-Archer Dynohubs, but they are different from the old Nottingham made ones(which are no longer made). Rumor has it that Shimano provides the insides for the current Taiwan built Sturmey Archer hubs. They also still make bottle generators and bottom bracket mount generators. They are not universally available in the US, but just about every European bike shop stocks them.

Actually, I was thinking about hub ones. And yes, they will slow you down, so will the electric producing clothing.

Cheeper does not always mean better (I do think the nano clothing is a miss though).
NASA spent booku bucks on a space toilet.
Russia used a diaper.

Pretty sure any astronaut you ask ('cept maybe Lisa Nowak) is going to say that was money well spent.

I'm with you on that one.

So, can we thank the Russian space program for Modern Depends technology?

I've never heard of bottom bracket generators.

We don't know that yet. It is in the conceptual stage; why not wait to judge it until it is on the market?

It is all about transferring energy. Although, technically you are already transferring energy to your shirt, you are just not harvesting it so I don't think it would slow you down as you are already being slowed down slightly by wearing clothes anyway. I just am doubtful enough energy is put into moving a shirt to power anything really useful.

On the other hand if my 5 year old wore one......

Hey, what about nylon shirts? They produce electricity. Especially if you are walking on nylon carpet! I used to transfer energy to my brother all the time that way.

You might not know that, but I do. You can't get free electricity. The power has to come from somewhere. This power will be you.

You are transferring energy already with the movement of the clothes, but the addition of electricity will require more energy. The only way for this to happen is either stronger wind or power diverted from somewhere else, like your speed. Just like generator hubs. You might think that because the wheel is already turning, it is free energy. Nope, you need to supply more power to keep the same speed. This technology is in use already. Honda uses the production of electricity to slow the car down in its hybrid cars.

The article you pointed to also shows this. I think it was a train station in Japan uses the power of the people walking over a plate to produce electricity. It might seem like free energy, but it isn't the people walking are supplying the power, this requires them to either slow down or push harder.

If the movement of the clothing can be efficient to power an iPod while walking, that would be good, since the the energy required would barely if at all be noticed by the walker. But for bikes, it is six of one, half dozen of another in regards to hub generators.

My point was why wait for some new technology when we already have one that does what you want, a human powered generator.

Pretty slick really, mount to the bottom bracket using the kickstand mount, and run on the tread portion of the tire. But they suffer from the same problem as the sidewall generator in inclement weather. I have one bike that came with one from the factory.
