Remember When

Quote: EvenBobThe salesman forgot to mention then if you treat it right you might get 2 million miles out of it which some people did. These early Corollas were absolutely incredible cars and at the time nobody knew it. I knew a girl who drove a Honda and we made fun of her constantly. because Honda's made motorcycles not cars. Everybody called it a 'Honda car' because we all laughed at Japanese cars.

I have been driving my Corolla a lot more than I expected. I think I am now at about 2000 miles this year and 1500 of it are back and forth to doctors appointments.
Does the battery recharge when power is restored? If not, I'd hate to have to disassemble the lightbulb to replace the battery 😄

I was actually wondering if the battery will last as long as the life of light.

I worked on an advanced uranium enrichment process called Atomic Vapor Laser Isotope Separation. We vaporized metallic uranium and then passed a laser beam thorough the vapor that selectively ionized the U-235 isotope; the ions were then removed from the vapor by electric fields. I became the lead designer of the process for a few years.

Thank you, that sounds both fascinating and exactly like a project that I would expect LLNL to be working on.
how does it selectively pick the isotopes you want? Or does this still involve a centrifuge?Quote: gordonm888Quote: DRich

The isotopes of Uranium, U-235 and U-238, have different nuclear masses and their resonances for absorption of photons (by their electrons) are at slightly different frequencies. You must be able to tune the frequency of the lasers precisely enough that the U-235 atoms absorb the light and knock off an electron without doing the same to the U-238 atoms. Once the U-235 atoms have lost an electron they have become ions with a positive electrical charge and can be swept sideways out of the flowing uranium vapor by electric fields where they deposit on "collector plates." The uranium on the collector plates is enriched in U-235 and the flowing vapor of uranium becomes depleted in Uranium 235 and is collected elsewhere.
There's lots of complicated technical details that are sensitive and that I am restricted from discussing but that is the fundamental concept.
I have to imagine that just about any knowledge of U was classified at one time. The googlebot says it was the 1940s before it was known that "early defense research determined that Uranium-235 is fissile [and] the more common isotope, Uranium-238 ... is non-fissile"Quote: gordonm888There's lots of complicated technical details that are sensitive and that I am restricted from discussing but that is the fundamental concept.

Very cool. I was involved in something that rhymes with that, separation of lanthanides in solution. They all ionize at different wavelengths and you can make them precipitate out of solution one at a time.
But doing it on the isotopic level- wow- that must be one heck of a monochromatic beam where 3 neutrons makes the difference if it ionizes or not! Beams like that are used for a few types of spectroscopy but that's at metrological rather than chemical processing power levels.

According to that bastion of all human knowledge, Wikipedia:
"Modern systems typically use the 238U absorption peak of 502.74 nanometers which shifts to 502.73 nm in 235U."

OK I know what Dieter actually does. He might have contractual obligations preventing him from revealing it, but I didn't sign the contract so I will.
He's the host of an English-language talk & entertainment show in Germany called Sprockets.

The porn shop around the corner from my first apartment had a similar deal. The front lobby was full of "non-adult" mainstream videos, and they rented them for dirt cheap - something like 1/3rd the price of the national chains.
They were clearly making their money on the back room - videos, novelties, apparel, and a wide assortment of contemporary smoking accessories (intended for use with tobacco only).

I knew the guy who owned the video store in my area and he said all his profit came from the backroom. He said the regular video rentals paid his rent and his employees and everything else and the porn videos were pure profit. There was never almost any time of day when there wasn't somebody in the backroom renting videos. This was long before the Internet and it was the only place to get them. It was mostly men but there were a lot of women that went in there together and they laughed and giggled looking at the boxes but they always rented something. I don't remember ever seeing a woman back there by herself that would be just weird.

This place was a usual pilgrimage for bachelorette party favors and the "Joe is turning 18, let's get him a magazine" excursions. Many of these outings included a participant that wasn't quite 18 by strict reckoning, or otherwise didn't have satisfactory ID. The front room was open without age restriction, but to go in the back, the clerk carded everyone. (There had been numerous busts in the past.)
Still, once you had a membership card, front room videos rented for something stupid like $1 a week, tax included, and they had a decent selection of classic films. Other shops were charging $5 for a weekend.
Other places were definitely less expensive for the back room content. One place didn't have a back room, just a binder listing titles. Pick a video number, pay the $7 for a week, get the plain brown wrapper, and bring it back on time or expect embarassing reminder calls. (They were $3 for a weekend on the "front room" titles.)

It's a novel, in the same size and shape as a Harlequin romance, but extremely obscene and usually detailing the kinds of acts that are also crimes. I assume the intended market was people who have something wrong with them. As a teenage scavenger I pulled dozens of them out of trash. But I also remember them being in mainstream stores, on the racks with mass-market paperbacks and products such as Harlequin. Not sure what they were thinking- maybe the buyers and merchandisers just thought "Oh, paperback books. Put them with the other paperback books." without investigating what they actually were.
I was surprised to find some of them command 2-3 figures as collectibles now.
It was actually a lot easier than half these newfangled bulbs where you need to either pull the battery to get to it from the back, or pull the whole reflector lens out to get enough room.
The modern permanent headlights are stupidly expensive if they ever do need changing, but most people just get a new car before the LED 's are expected to burn out.
Quote: DieterI don't remember the old big headlights being all that complicated. The aiming adjustment screws were separate from the mounting screws; pull the wire, pull the trim ring, and hold your hand (gloved! It's hot!) so the glass doesn't hit the pavement. Jiggle the new one in, secure it with the trim ring, and wire it up.

Mined burned out at the same time at 64k miles, or just under 5 years. I thought it was electrical, but no, it was the LEDs failing at the same time. Bumper to bumper warranty replaced them free though. I was glad I checked because I didn't actually think they would cover light bulbs.

So you changed a lot of headlights on 50s and 60s cars then? They were always burning out And I always carried at least two. Same thing with brake lights And the thermostat. You could always tell when the thermostat was bad'cause you didn't get any heat coming out from under the dashboard.

A handful. My recollection is that they were all very similar until the late 1970's when rectangular lights started to appear. Those still had the same basic mechanism, just with corners, and maybe no alignment notch.
Cars, pickups, motorcycles, farm equipment, bulldozers... headlights is headlights.
In the 1990's, the little bulbs that slipped into the reflector/lens assembly started to show up. Those were different than the big glass bulb with the fresnel front and the mirrored parabola in the back.
Quote: EvenBobJust watching old car video and I was remembering the days when you actually carried extra headlights in your trunk for when you had to change them and what a pain in the ass that was. This was the 60s and 70s when you did all the car work yourself. There was no fast oil change places that would also change a headlight. The hardest part was centering it so it wasn't shining up into the trees. The good old days..
