@#13,

A lot of the top down cameras use 120mm film which was hard to get developed 10 years ago. Unless you know of a good pro shop you might not be able to develop it at all. Assuming you can find it.

Besides, part of the appeal of this is the artifacts you're getting and the juxtuposition of the old-school camera with digital prints.

I'll have to try this with my old Mamiyaflex.

I have to say that from my own personal experience it IS possible to kill a magnetized card with magnets. I have a purse that closed with very strong magnets and kill half a dozen BART cards and an access key for work before I undid the stitching and pulled the magnets out. They killed the BART cards the fastest and didn't appear to harm my CCs but once they killed my access card I said to hell with it.

I rather suspect the demagnetization depends on the amount of time and the quality of the card, as well as how strong the magnets are.

Apperantly I need to clarify my comments. I was attempting to say that I was old fashioned, hence the link between screaming children being removed and dressing up for things. I understand that performers want people to attend their performances. I used to play in a symphony, myself. I do, however, also belive that an event like the ballet or a concert warrants at the very least business casual. And that's what I attended in when I was a broke college student. Hell, that's what I STILL attend in, since I don't own any formal clothing. The only kinds of concerts I attend in jeans are the ones where you end up with moshers.

I see no reason why thinking an event deserves more care in dressing should be seen as elitist, either. After all, you can pay $500 for a pair of jeans these days, and I still think you shouldn't wear them to a concert.

On the original topic: Scottfree, one could argue that the prom is social education and therefore something where the school could regulate the dress code. It would be interesting to see how that one turned out, though, because that would open a really interesting can of worms.

This is nothing like water injection. That works because when you heat up water, it expands and that heat was originally waste energy. The expansion provided by the water would probably allow you to reduce the amount of fuel you inject and thus increase the efficiency. This is talking about using electricity to split water in to hydrogen and oxygen and then injecting the hydrogen into the engine.

Electrolysis, as someone else already pointed out, is increadibly inefficient and regardless of whether YOU can detect the load on the engine, it's there. There is no free lunch. To use your example: plug a map light into your cigarette lighter. Turn off your car and leave the light on. It'll still kill your battery, it just takes a while. When you turn the car on, the engine has to run harder at a given speed in order to charge the battery. It's no different if the car is running when you're adding that map light.

From what I know of combustion engines and thermodynamics, this sounds like bunk.

I haven't had a chance to watch the video, but I feel I have to reply to #70. I firmly believe you SHOULD have been denied entry at the very least to the ballet.

Manner of dress conveys your respect for the situation. Showing up to a performance of any sort in jeans says "Eh, this is kinda entertaining, but it's not worth it to dress up." It's insulting to the performers and the incredible amount of effort they put into each performance. I also happen to think one should dress nicely for a nice restaurant but I'm so old fashioned I think children should behave or leave, so what do I know?

Showing up in that dress showed that she didn't care at all that the administration had made their dresscode clear previously. Offering to cover up is just foolish and I don't think I would have accepted it in the administration's position, either. It's easy to take a jacket off, after all, and putting on a totally different dress was probably NOT what she offered.
