Nutsngum posted:Watching the lightbulb one, its amazing just how much of a game changer LED lighting has become over the last 5 years or so. We had (at least in Australia) the period where the downsized fluorescent lights became popular for almost a decade but still suffered from breakage and poor/shoddy build quality. Suddenly LED has become standard in a form that is just superior in every way to its predecessors. They are a magnitude more efficient, smaller to a huge degree if you so want it, available in every single possible colour just about and sometimes variable, and a longevity in the decades. My observation about LEDs is that the first generation (past the ones that were dim as hell) have lasted forever, but more modern ones break with suspicious consistency long before 10k hours. Feels like lightbulb manufacturers reached the age old realisation of "if I sell them bulbs that last forever, THEY'LL NEVER NEED TO BUY MORE BULBS".

Lurking Haro posted:Modern LED bulbs are often driven at a higher current, making them brighter but also last shorter. Ironically the exact line fed to the general public by the members of the Phoebus Cartel in the 20s and 30s, when it was in fact good old fashioned planned obsolescence. There is no manufacturer incentive to create 25-50k hour LED lights for general consumption because it destroys turnover. While it's perfectly possible for manufacturers to make these kinds of bulbs, and they do in smaller numbers, they can also make LEDs bulbs of far lower quality for less money. In that way, they can create a two-tier market of cheaper LEDs and "premium" LEDs, which in turn will cause people to continue to buy 2-5k bulbs forever because they are at a noticeably cheaper pricepoint despite being a massive false economy.

ugh whatever jeez posted:LED bulbs suck, still so much more expensive, often have weird color temps, get dimmer over time and break just as well, even expensive ones Eh. We switched almost 100% to LED a couple of years ago and its kind of nice not having a constant stash of light bulbs. Of 30 or so bulbs (cheap Costco ones), we had maybe 2 duds. Now compact fluorescent bulbs can go to hell.

I got lucky and was at Home Depot the day they were switching out Philips' LED line for the newer model (IIRC they're like 50 lumens brighter which is nothing, and slightly differently shaped), and I snagged a full case each of 3 different kinds of LED bulbs for $.01/bulb, it's essentially a lifetime supply even if we leave LEDs here when we move out into an actual house. e: I've got regular screw-in, indoor flood and outdoor flood, they're all 5000k though so my circadian rhythm is hosed

Yeah, I got the Costco ones couple years ago that had the instant ComEd rebate (which was like 80% or 85%) at the register, so they were dirt cheap. Everything from dimmable can floods to 60W equivalent lamp lights. I also got the smaller socket overhead fan lights, mirror lights for the baths, and replaced my outdoor house light fixtures as well. With the rebate they were dirt cheap. Definitely less than $150 to replace all the lights in and on the house and have a stash of a few extras of each.

Platystemon posted:Tokyo imported AEG generators from Germany (50 Hz). Out west, where they couldn't "send" any of the electricity they generated to the devastated east, things went on pretty much as normal. There were huge outpourings of support and donations of money and supplies, of course, but no changes to electricity use. I felt a little guilty enjoying my air-conditioned train rides in Kyoto, but it was such an improvement over the electrical austerity out east. (It's a lot more common now throughout the country to see energy conservation efforts like vending machines that only light up when you approach or public lights that are only partially lit. There's usually a sign explaining why.)

Not really, a single factory in my home town uses more energy than the entire rest of the homes of the 35,000 people who live here, and we have a dozen or so.

That’s the kernel of truth at the heart of of the fake news that ONE CONTAINER SHIP IS WORSE THAN A MILLION AUTOMOBILES! For most other pollutants and global warming potential? Not a chance. And guess what: incandescent bulbs were also made in China and because they burnt out faster but aren’t physically smaller, they required more ships.

How about radio-frequency electrodeless lamps? Pros:
Cons:
Oh, there's actually a pretty decent Wikipedia article about them - Sulfur Lamp. Why use boring simple LEDs when you could use one of these? quote:The sulfur lamp consists of a golf ball-sized (30 mm) fused-quartz bulb containing several milligrams of sulfur powder and argon gas at the end of a thin glass spindle. The bulb is enclosed in a microwave-resonant wire-mesh cage. A magnetron, much like the ones in home microwave ovens, bombards the bulb, via a waveguide, with 2.45 GHz microwaves. The microwave energy excites the gas to five atmospheres pressure, which in turn heats the sulfur to an extreme degree forming a brightly glowing plasma capable of illuminating a large area. Because the bulb heats considerably, it is necessary to provide forced air cooling to prevent it from melting.

Our company recently covered the entire warehouse and office building roofs with solar panels and some huge grid tie inverters. It's been a month and the power company still hasn't been over to switch us over. It's coming into our summer so peak opportunity to feed back into the grid saving some coal.

From a few pages back:quote:Using VCR for backups I never got around to trying with VHS, but using a miniDV camcorder over FireWire for backups was very easy and gave pretty good capacity on a tape (10GB or so, depending on the level of redundancy) and seemed reliable enough, but was slow (real time, so 1 hour for 10GB). Also from a few pages back: quote:TV broadcasts of sound to load on 8-bit micros If you were quiet enough in the room it was possible to use a microphone near the TV speaker to record this to a tape, as the signals were pretty robust to cope with being on low quality, cheap cassette tapes

I suppose they would find out when you brought a broken CFL bulb to the designated disposal site, because it's illegal to just dump them in the trash because of all the mercury. Also, if it was on right before you broke it then mercury vapor came out even if you didn't get mercury dust everywhere, so you're probably going to die. CFL bulbs are great.
