Florescent light bulbs?

    Al Gore came on Opera yesterday and said we could save 20% of the
    energy our light bulbs use if we switched to more expensive florescent
    bulbs. These bulbs last longer you know. But are you aware that the
    light bulb companies are conspiring to keep florescent bulbs off the
    market? They charge you more for them already, but Tesla invented a
    florescent bulb that is still burning in the Tesla Museum 50 years
    later. If we all used his bulbs we would never have to worry about
    screwing in light bulbs. So the answer to the most important question
    of the day: How many scientists does it take to screw in a light bulb?
    Really should be none. Because we don't have to ever change our light
    bulbs in an ideal world.

    But can anyone tell me how I can get a hold of one of these Tesla bulbs?

    We save only 20 percent compared to incandescents ?

    There must be something about Tesla stories that
    magnetically attracts funny maths.

    20%, is what Al Gore said. He would know better than me. What do you
    think the electric power needs of the florescents would be? And where
    can I buy a Tesla Bulb?

    If you live out in the boonies where the power fluctuates the florescent
    bulbs only last twice as long as 'regulars'. Given how much extra they
    cost that's not too good of a deal. Given that they seem to embody more
    energy used to produce I suspect that it's not a good deal in terms of
    total energy used, either.

    I like Al Gore's scifi movie, "An Inconvenient Truth" where he preaches
    about the myth of global warming from the backseat of his armoured,
    7mpg limousine.

    I think you need to listen again. Fluorescent bulbs save 80% compared to
    incandescent bulbs.

    For the cheap flurescent bulbs there is a possible problem because they take
    a few minutes to achieve full brighness, so they are not so good for a
    basement / loft area where you usually want 100% brightness from the first
    moment, but in areas where the light is generally 'on', you'll make big

    I have a rule of thumb that each bulb saves about £10 / $20 each year if
    they are 'main' lights for an area.

    He is wrong about a lot of his theories. He claims that global warming
    is caused only by C02 gasses, when in fact all greenhouse gasses are a
    problem, and ozone depleting gasses as well. Hydrogen eats away at the
    ozone and the pure H20 steam from nuclear power plants is a greeen
    house gas. Even the electric vehicle would just drain the power grid
    and cause problems if we were all using them. The only real solution
    is to curb population, because even if we all switch to florescent
    light bulbs there will be 10 million more americans than there are
    today in just a few years. But you don't here al gore talking about
    celibacy do you?

    Wrong about the myth. GW is most probably real - if it wasn't the Petro
    companies wouldn't be channeling millions into 'independent organisations'
    to attempt to rubbish it.

    80%?? No way!! That is like a FREE ENERGY MACHINE!!! Are you telling
    me that we can take what's left over from the 20% of the energy it
    uses, and use it to power the rest of the appliances in our house?? WHO

    Are you able to produce a direct quote where Al Gore says that GW is caused
    ONLY by CO2 ?

    Rubbish, I can buy an 11W or 18W CFL at Morrisons for 49p ea !

    Is it ?

    << Compact fluorescent (CF) lamps are lamps of choice
    for those looking for an energy-efficient alternative to
    incandescent lamps: they are praised for consuming
    as little as one-fifth of the power and lasting up to 13
    times longer than incandescent lamps. From a designer's
    viewpoint, the increasing variety in shape and colour and
    the small size of CF lamps have made them more
    versatile and acceptable than traditional long-tube
    fluorescent lamps. >>

    Use 20% I think he must mean.

    If a standard 100W incandescent bulb has a rated lifetime of 1000 hours
    it'll use 100Kwh over its life,
    The fluorescent equivalent uses 20W and (according to your claim) lasts just
    2000 hours, so it uses 40Kwh over its life, which represents at least a 60%

    However, one of the features of the boondocks is that NOT MANY PEOPLE LIVE
    THERE, so since most people can expect 5-8,000 hours from the same bulb,
    they'll get 60 - 80% saving per year per bulb.

  18. Actually, the savings may be negative.

    A fluorescent closet light is LESS efficient than an incadescent when
    total lifteime costs are considered.

    In general, fluorescents make sense if the lamp is continuously run more
    than four hours a day.

    A reasonable guess is that fluorescents are only cost effective in ONE
    HALF of most home light sockets.

    Yeah, and Edison's light bulb has been burning at his lab for 50+ years too.

    You might want to read up on the relationships between bulb efficiencies and
    lifetimes; it's generally an inverse relationship (both for incandescents and
    flurorescents, it's just that fluorescents start off much better).
