Vast Antarctic ice shelf on verge of collapse

[IceColdBrewski]

So all the extra ice on the continent is pushing the ice shelf out to sea and it melts and weakens.

A special congrats goes out to the Cambridge-based British Antarctic Survey for taking this long to confirm Archimedes' displacement of a liquid law.

Here is an interesting little video. All about a possible new light
bulb.

Wonder why someone doesn't complain about all the fireworks that are shot off in dear old SA on holidays. You know how they
bother animals and some people. But no one I know of on here
has ever objected to them. Guess you like them.

I hate fireworks. They annoy the out of me. So a couple times a year I close out the outside world and try to ignore the noise

just thought I'd share.

Very impressive. More light for half the power would do a great deal towards energy independence...

So this light bulb will save the planet, eh? Oh well, at least I can tell people I'm going green. Actually, if anyone asks me this, I'll pull out my wallet and lay a stack of Benjamins (okay, Washingtons!) on the table and say, "this is the only GREEN I believe in!"

But if the bulb will save me $$$, then I'm all for them. Really.

Wow... part of an article:

The plasma bulb uses 250 watts, and achieves around 140 lumens per watt, making it very bright and highly efficient. By comparison, conventional lightbulbs and high-end LEDs get around 15 and 70 lumens per watt, respectively.

I use the compact fluorescent and planed to switch to the LED bulbs soon. Maybe I'll wait for these, assuming they can be made to lower power levels.

What? You don't want a 35,000 lumen bulb?
It would be like your own little sunrise.

I kind of doubt it.

Remember that the light comes from plasma (super-heated gas).

It would take quite some time to scale that down to a light bulb suitable for houses, I would imagine.

I didn't know they made LED for the home. I know about
the flashlights, have one, but I cant recall see bulbs for
the home. How expensive are they?

RG you said "I kind of doubt it.

If I remember correctly the rated this new bulb by
wattage, couldn't they just scale down on the amount
of watts used? I could be wrong and probably am.
To simple.

I think so too, and come to think about it, I'll bet they are no more efficient than th new LED bulbs available if they were reduced in size.

I have used the flourescents for some time now. I recently replaced all with the FEIT Daylight series and gave my regular compacts to my neighbor. They have a few lumens less than the regular compacts, but they have a better color spectrum over the soft white. I bought six cases of 12 when Lowes had them on sale for $0.99 each.

There is an 800 lumen LED bulb available that uses les than 8 watts. That places it well above the 70 watts the article says at at least 100 lumens per watt:



There's also a 9 watt version said to be ewuivalent to 70 watts, but it only 308 lument in clear of 594 in frosted That doesn't make sense, but tghey claim it's due to the color:

It isn't that simple. I'm not certain, but I think as you reduct the charge on the gas, you have a near linear effect, but you cannot reduce the heating in a linear manner. As you approach low power usages, you don't have enough heat for the plasma. Assuming that is true, it gets more efficent as you increase the size and less efficient as you decrease it. It may be the volume vs. surface area instead, which would make the changes even more dramatic. I'm just making an educated guess here.

So do I have any takers for my carbon credits?

I have many left over.

Holy smokes, I looked up the LED bulbs, and one
equivelent to a 60 watt bulb, 119 bucks.

Guess I will pass on those.




Lots of money

Yes, but I was planning in only a few where I use lighting the most, and I would wait for the price to drop at least a little. I think we can expect the price to come down even more as more people want them, and more compe ion comes in. Maybe to about $10 each. I like lowering my energy consumption so I use the compact fluorescent. However, they are less environmentally friendly than regular bulbs! Sure, they reduce your carbon footprint, but what about your mercury and phosphorous footprint? These are items that are actually rather costly when properly disposed of. You don't just put these in the trash, and there should be a law against doing just that.
