    Pretty cool!
    Goes without saying seeing comets close up makes them a little less mysterious.
    Glad to see humans forging ahead with intense curiosity in spite of what we do to each other here on earth.

    Talking about electricity, I changed 6 bulbs and three fixtures in my house to LED lighting and dropped my electrical bill $15 a month.

    The only strange thing that occurred was the light above my kitchen sink has 7 LED bulbs with a clear lens, so the light isn't diffused and it gives any item 7 shadows.
    7 shadows LOL
    That might mess with the food pics :)

    Amazing how much LED's can affect savings.
    The wife is all over this here.
    She's changed whatever she could inside and out.

    We also ended up giving the big plasma TV we had away and got a newer LED model.
    It's looking like doing that in addition to the bulbs has dropped our electric from $330.00 to $240.00 a month.

    Interesting hypothesis. I'll await for testing of the model to see what happens and what comes out that.

    The comments at the article are interesting.... Some better than others.

    Still doesn't answer the burning question, the chicken or the egg?

    Questions!

    Is lightning strictly pure DC or is it a modified version of direct current?
    Can the voltage level of lighting be measured and would it be the same for every strike?

    Which is the potential of lighting?:
    Earth or the point at which the bolt of electricity jumps to?

    I'm asking because I really dunno...

    Are there any realistic ROI calculators around? I'd like to convert our RV over to LED, as well as our 2,900SF ranch house and barn, lighting is a mix of CFL, halogen, luminescent and mercury vapor. Mix of LCD, Plasma and CRT TV's. I want all of the home lighting, fans, etc. to tie into my mixed Insteon and x11 home automation, so will either get smart bulbs or controllers for them.

    While in the middle of a remodel, the lighting by itself is cash prohibitive. However, from an ROI and resale value it still would seem to make sense. Any good tools you've seen ?

    We've experimented with some of the lower priced LEDs for our fifth wheel.
    I've not seen a massive benefit over cost for them since we don't run the trailer lights a lot on batteries.

    What we did was buy battery powered LED table lights more for mood lighting versus utility.
    Those things last for months on replaceable batteries.

    The lights in the trailer used most by us are in the kitchen area and the scare lights on the outside.
    Could be some benefit there...however in most areas we camp outside lighting has to be off overnite unless it's subdued lighting.

    Well enough off topic...
    ...or is it :)

    Well, it IS the Off-Topic lounge! Besides which, when looked at correctly, most all things are science, which is supported by math. We can view this as a bio-financial exploration of electro-physical compute-intensive bio-habituated phenomena. Or I'm just a damn geek.

    If there's anything human on mars it's probably a Starbucks.

    "Star Stuff!"

    Although somewhat dated I liked Sagan.
    His calendar of time brought it home for me.

    I replaced all the 50W halogens with 5W LEDs. :) I can't replace three lights unfortunately but at least most are done. :) we've been doing pretty well energy rise until the winter came. We have electric heaters.
    We use oil filled electric heaters. They really help keep the bill down.

    Keep in mind when Carl Sagan was around we were still trying to figure out the string theory and chasing the Higgs boson and to find earth like planets revovling around stars in the habitable zone. All of these have come true in Neil's time....just my 2c.

    Another question:
    How far can particles be broken down.
    Does infinity travel in both directions and can this be worked out mathematically or will it be solved by mechanical research?

    Asking because I don't know.

    Laura, after you read Simon's book, please let me know your thoughts. It had some really nice correlation between science, scientists and their faith. It was really eye opening in the sense that people were a bit more tolerant back then compared to today and accepting that faith and science can coexist peacefully.

    According to the string theory particles can ultimately break down into just vibrations. This is of course a very simplistic view. Brian Greene's The Elegant Universe is a good place to start or his show on PBS is equally good.
