    yes, steel is terrible, but at least point out what's wrong with it.

    Taconite is the primary source of iron ore, that is used to make steel, the debris remains of taconite are highly toxic, and there were companies dumping taconite debris in the great lakes, all the way into the early 90's now in the US it all has to be stored on land, but it's Toxic, and leaches into water! i guess nobody cares what happens in northern Minnesota though, so who cares if making iron released tons of toxic waste.

    secondly, steel can only be produces with a very hot flame, coal needs to be modified to even achieve such a hot temperature, and a load of ozone is produced by steel production, ozone is good though right? not in the lower atmosphere, it makes allergy sufferers suffer worse allergies, and there are days when in steel country they issue advisories 'not to go outside' due to the high ozone levels, usually a stagnant pressure system that keeps the ozone locked in one place for several days is the cause for such 'advisories.'

    oh and remember how i mentioned iron production creates tons of pollution? Guess what! Steel does too! http://www.sprol.com/?p=373 and US steel was caught doing it in 2005, dumping toxic slag into waterways.

    Aluminum also produces toxic waste, but compared to steel, it's trivial for one thing most soil world wide already has a small percentage (around 1%) of aluminum oxides already...

    although the carbon factor with aluminum is greater than with steel, it's also one of the better recycled metals. steel and iron sadly, do not get recycled nearly enough.

    everyone i know turns their heat down as cold as they can stand it in sweaters. if not using single room/person heating options.

    lights that produce heat yeah that heat has to go somewhere, but a normal house doesn't have enough convection to make a difference in personal temperatures. take for instance a split level house that lacks doors (common design flaw people 'like' open floor plans) all the heat rises to the top floor, causing as much as a 10 degree difference between the top floor and the bottom floor, yes lights that produce heat make the TOP floor warmer, but the ones in the bottom floor help no one on that floor at all!

    the only way to really benefit from the heat from an incandescent bulb is to sit above it where you WILL get personal heat, rather than minuscule heat at the ceiling.

    people saying convection works, then why do ceiling fans have a winter mode? huh, in practice the only devices that can produce convection warming are baseboard systems. forced air won't, light bulbs won't you need a LOT of heat to make convection work.

    besides, even if you live in alaska, in summer months the cooling bill increase from incandescent lights will more than offset any supposed benefit, in the winter. sure, you could have 2 sets of lights, one for summer and one for winter, or waste a lot of time changing (and breaking) bulbs.. the energy savings already offset the cost of some LED bulbs (especially if you have children, those unbreakable bulbs are a godsend)

    mass producible, affordable, quality LEDs are nothing but good.

    plenty of other ways to use electric heat. where i live, wood pellets are cheaper than electricity, for heating, not to mention corn burners, if you stock pile the corn in summer you can pay about 1% the cost of electric heat.

    you do realize, that except for lighting, and simple fans, virtually everything requires DC power to run.

    so putting in a rectifier into lighting doesn't add $10 to the cost of a light bulb, it adds about $2.

    in order for LEDS to be energy efficient, they require rectifiers anyways, since they only stay on 35% of the time when run straight off AC current. besides, to perform dimmer functionality an IC that can switch the power on and off rapidly is needed, and it's easier to put it in the bulb.

    and some people aren't bothered by flicker, I for one have a very low sensitivity to flicker. I've had headaches from using older style CRTs but only when i was 'changing' my viewing behavior, eg: vacations away from the PC i'd be prone to headaches from not being around the flicker, and maybe when i first got back to staring at a monitor all day.

    OTOH, i easily get headaches from both caffeine, and aspartame. oh yeah, and i'm very near sighted, perhaps my lack of sensitivity to flicker has something to do with the quality of my optical inputs.

    "For an imaginary cycle of 360 degrees of the AC line, about 26.5deg (1.2msec) pass before the line gets to 75V and the LEDs start to emit light. Then the LEDs are on for 127deg (5.9msec), and off for the remaining 206.5deg (9.6msec). That means we get a 5.9msec hump or pulse of light every 16.7msec: The LEDs are actually ON only about 35 percent of the time "

    not good, although a full wave rectifier can be built for less than $5 worth of parts at radioshack.. oh hey, and some bulbs actually take advantage of being able to make LEDs switch on and off quickly to emulate dimmer functionality.
