   Perhaps Birkenstock-only stores have a contract with Birkenstock that defines transfer of product from Birkenstock to the store as not a sale. Could be a consignment. Then the first sale would be to a retail customer (or to Amazon, in the c

   Seconding an earlier post in thanking you for your perspective on these results.

   Agreed, and thanks. It's clear that dropping panel costs really wouldn't affect the installed bottom line much. I just focused on installation costs, which in all cases seem far less than 50% of the overall system cost. This sugge

   Me too. When I see that, I wonder what how it would felt to be an SSME design engineer viewing that behavior. I sure wouldn't have expected my design to shake like a leaf in the wind.

   Thanks for this, it helped me understand the matter being discussed.

   I loved watching startup of a Diesel engine that probably occupies more volume than my house, thanks. But for sheer amazing operation at the very edge of what we know how to do, I like [1]. There's just something about running !% short

   According to this [1], installation costs are way less than half of solar panel costs in 2016 US$. Looks like 10% - 15% depending on the installation case. See Figure ES-1. [1] http://www.nrel.gov/docs/fy17osti/674

    "We know what that means." I don't. I found the parent's post a bit thought provoking. If you'd expand your thoughts, it might be interesting.

    I have zero domain expertise in cryptocurrencies or Ethereum, but much experience with unexpected failures of "guaranteed" things and processes. To use your analogy - I'd view the bridge design engineer as having guaranteed t

    It doesn't seem like you have any behavioral problems with alcohol. Over an extended time span, you might face other issues [1]. Shorter life and a merry one vs. longer life and perhaps less enjoyment. A choice that merits thought and

    Yes, it's possible with a high degree of confidence to distinguish natural from synthetic diamonds and for synthetics, to determine which method (HPHT or CVD) was used to make them. The IIDGR [1] company makes a series of devices (Diam

    I guess it won't hurt to offer my own anecdata point about idiot medical billing. Stanford hospital billed us for an IVF procedure. However, we were in Paris at the time they claimed my wife was undergoing the procedure. It took going

    There aren't many tried and tested solutions for grid energy storage. Pumped hydro is probably the best known and longest used. It's reliable and low risk. It's only practical if geography includes two adjacent large bodies o

    To give a feel for the forces involved, I have read [2] that the pressure generated by ablation that compresses the W88 fusion secondary is around 6 petaPascals. For comparison, the estimated pressure at the Earth's center [1] is aroun

    Radiation from the bomb will immediately vaporize a thin layer of material on the portion of the asteroid exposed to the detonation. This happens very fast and imparts an impulse to the asteroid. It's an ablation blow-off event. This w

    The nuclear lightbulb is new to me, thanks for the link. Has anybody thought through the engineering of those silica reaction vessels (I haven't searched)? I don't think it can work. If I understand the concept shown in the Wikipe

    Maybe. There is apparently some evidence and viable theories for ongoing fission reactions in localized regions deep in the Earth. Commentary [1] on a report in Nature [2]. Neither of these seems to be paywalled. [1] http://www.

    Not contradicting your statements, but I thought I would offer a single anecdata point for a different perspective. I take Alprazolam (generic for Xanax) in a low dose (0.25mg) 2 or 3/day. This makes the difference between my being abl

    You're right - with a bit more thought, I would have given a less "terminal" example of sudden unavailability. Will keep that in mind, thanks.
