Actually, the AC does not know what he's talking about. Older space heaters (which do NOT come in 100W varieties; the lowest you can get is 500W and that's rare) may last decades. Newer ones (being of typical made-in-China quality) last not much longer than a light bulb... five years on average, despite costing 25x more than a light bulb. Conversely I have multiple light bulbs with going-on 13 years on 'em.
Yeah, the space heater kept the pump house warmer... needlessly so. So it was mostly =wasted= energy.
See, that's what you don't seem to get. For some uses, 100W is a very nice heating element. But you can't buy that in a regular heater, so you waste a whole lot via excess heat with a heater that uses many times the energy of a light bulb, and will not provide =steady= heat at a low setting (which has to be jury-rigged; no heater comes with that low of a setting). Try raising chicks with heat that's on/off/on/off.
I heat some other areas with space heaters, and have done so for over four decades. I'm painfully familiar with them, in all their incarnations.
So it sounds like (assuming some magical energy source) about 1200kwh per kg would be a decent compromise, 3-4 weeks in transit being not so onerous. Even 54 days in cramped but modern comfort doesn't sound bad compared to back-when ocean crossings.
Same here... it's just right for the pump house, or the chicken coop (which needs the light anyway). Why run a heater (500W to 1500W) when a 100W bulb will do? thermostatic control on the heater? Well, there's the problem... most heaters insist on coming on at their lowest setting at 55F, which means they run WAY more than is necessary. Yeah, I could add a thermal-controlled outlet, but it still won't be the =steady= heat of a light bulb... having to reheat the cooled-down walls every time it comes on means the heater uses more power to do the same work. Meanwhile, I could use a 100W bulb to keep the same space at the desired steady 40F, at a fraction of the cost.
(I got to experience this firsthand last winter... 100W light bulb was used to keep the pump house from freezing. Worked fine and cost about 10 bucks a month. While I wasn't around, some idiot decided it needed a space heater instead... next month's power bill, running that and NOTHING else, was over $150. So tell me, which is more energy-efficient??!)
Then you must live in a cave. I'm almost 59 myself and as I say above... in all my enclosed fixtures are one CFL and one incandescent. Those are turned on and off a lot (and the kitchen lights get used a lot of hours) and I have not replaced a single one of those bulbs, of either type, since I bought the house in 2001. (And actually, most of the incandescents came with the house, so I don't know how much older than that they are.)
The 3 bathroom lights are all exposed incandescents and they came with the house. Probably installed when the house was renovated in 2000. Turned on and off all the damn time.
But I lose CFLs in the open light fixtures, and in the porch lights, pretty regularly. The first one I bought, back when they were new, lasted about 7 years. But since then the most I've gotten from a CFL was about 3 years, and 2 years is more like it. Oddly, the CFLs outdoors last the best (and get exposed to both heat and cold, since the temp range at that house is -10F to 122F). At around 2 years, they start to get dim, then soon overheat... sufficent to smell like they're burning, and brown the socket.
The main issue I've noticed isn't the brightness, but that the light from CFLs has a fuzzy quality. Nothing has a sharp edge. It may be partly cuz I see a little ways into UV (CFLs, like black lights, are *extremely* bright to my eyes), but it's still annoying as hell, and makes them a no-go for places like kitchen and bathroom, where one uses sharp things and may need to be precise.
True, but it's not really fair to expect every consumer to become an expert on light bulb specs. It's very much like computers, or cars -- they just want the damn thing to turn on, work reliably, and not cost too much. They don't want to have to know all about its innnards.
As I said above, in my experience it's been the CFLs in open lamps that degraded (the ones in enclosed fixtures, all of which share space with an incandescent bulb, are over 12 years old -- never replaced any of those bulbs of either type).
At about 2 years, the CFLs in the open lamps lose brightness. I've learned to throw them out at that point, because they ALSO start running really hot -- hot enough to brown the base of both bulb and fixture.
The ones in my enclosed fixtures get turned on and off more (several times a day), while the ones in open lamps are usually turned on/off once per day.
I haven't found that to be the case. The CFLs in enclosed light fixtures... well, they're past 12 years old now. But I replace the ones in the open lamps regularly (they last about two years on average). Same damn bulbs, out of the same package no less.
BTW I haven't replaced a single incandescent in that house since 2001. (All the enclosed fixtures have two bulbs, one CFL and one incandescent)
But the numbers you link to don't really show that. What they do show is a slight spike over the next year or so, followed by a considerable drop across all types of crime.
How many gun deaths per year worldwide, exclusive of war zones? Since the world claims America has more gun violence, I'll arbitrarily say ours is 2/5ths of the total, so let's pull a number out of our ass and say it's around 100,000 annually worldwide. So in 100 years, you get about the same number of deaths that the average totalitarian regime manages in 10 years or less.
Imagine an alien trying to classify domestic dogs by appearance. No doubt they'd decide the Great Dane and Chihuahua were different species.
I have a theory, thus: domestication caught proto-dogs at a point of evolutionary mutation (which according to one theory, happens largely in bursts of many concurrent mutations, most of which are not viable and die out). Genes survived under human protection that would not have, had dogs not been domesticated, and led to the wide variation in basic canine types (which goes back as far as there are records). No other species has such wide variation of viable types.
What if a couple million years back, proto-humans were also undergoing a burst of mutations -- leading to a lot of variation within the existing species, and most of which died out. That would explain why they look so unlike, despite apparently being concurrent.

When I find more than one program dangling off the same name, I become suspicious of all. :(
None right now, being I'm stuck between houses... but a nice soft reading light is high on my agenda.
Ah, okay, I see... so it's feasible enough, if only there's some reason to GO there.
I'm wondering what might be on Mars that has enough value to propel someone to do it. (Now that we don't have the Cold War driving it.)

I was trying to be conservative, but ... looks like I erred by an order of magnitude or two. Yep, guns are safer than batshit-crazy dictators.
Fact is we could probably have recreational gun battles in the streets and still never catch up.
Ah, thanks. That really puts it in perspective!

I'll care next time I have to buy light bulbs. We'll see how LEDs are doing then. CFLs are for the birds.
How long would it take to get to Mars if one could snag the 'go fast' required quantity of fuel out of space as one went?
Oooh, thank you for the link. So many nice options!

I seem to recall the assault weapons murder rate is exactly zero... what's the murder-by-blunt-instrument rate, do you know offhand?

Trouble is, a few million (or even a few tens) years ago, fortified foods didn't exist.
Damn! You've uncovered my nefarious plot to replace cattle with vegetarians!!

I think that's probably just plain fact. Hence, we're here to defend our theories, and they're not.
