Google put one of these on the floor of the East coast, rather they are currently engaged in placing one along the east coast for (as I remember) off-shore wind power bus connections

Aside from both using the word "cable", there is nothing in common between these two projects. One is an undersea fiber optic cable whose primary purpose is scientific exploration, the other is a commercial venture for transporting bulk electrical power.

Unfortunately, it appears that there is another important difference: NEPTUNE is built and operating, whereas the Atlantic Wind Connection appears to have not made much headway, let alone built anything, in the past couple of years. They haven't so much as done a press release in the last eight months. The current goal is to build one section along the New Jersey shore. Estimated completion date: 2021.

The most recent bulb I replaced was the one in my oven. It had been burned out for years, but I decided to replace it when I was in there to replace a heating element. $4.50 for a tiny 40W bulb! I suppose a run-of-the-mill bulb isn't meant for use in a 500F environment, nor necessarily (in the U.S.) to be run from 2-phase power.

Yes, it was an incandescent - this is one situation where energy efficiency in lighting is a rather moot point. Bulbs in refrigerators, on the other hand...

If bitcoin was trading at something like $600 beforehand, why would anyone bidding $450 be surprised that they lost out? If these bitcoin boosters are so firm in their belief that bitcoin is as fungible as any other currency, shouldn't they have bid at something like the going rate?

Put differently, if the U.S. was auctioning off a briefcase filled with €100,000, and the exchange rate is presently €1 = $1.37, would anyone be surprised if a hedge fund bidding $1/€ lost out?

Comment Re:CPR (Score 1) 83

The first chest compression might work a bit, but then you go flying across the room. The shock from hitting the bulkhead might provide another stimulation to the heart, but after that you'd probably just roll up into a ball or something and drift around a bit.

The Hollywood fairy tale of CPR, or a sudden thump to the chest, causing someone's heart to start beating again is just that - a fairy tale. Even today, with CPR knowledge relatively widespread, most people that have a heart attack (i.e., the heart actually stops beating) will die of it. The purpose of CPR is to keep the rest of you - principally your brain - properly oxygenated until definitive medical care (drugs, defibrillator, oxygen, stents, etc) can properly revive you. The notion that astronauts are going to perform CPR on one of their colleagues for several hours, through re-entry, and all the way to a hospital is laughable. Even if the astronaut survives, all that's left would be a turnip that can breathe.

Comment Re:Kickstarter/Amazon still get their cut (Score 1) 448

This is why there is zero oversight from Kickstarter/Amazon - they get their 20% cut if the projects gets funded

I gotta make some correction there - it's not a 20% cut. Kickstarter get 5%. Amazon get 3-5% depending on several factors. Granted, it's still a lot of money, and provides a powerful incentive for them to have as many projects funded as possible, but you're overstating it by 2x or more.

Comment Re:For a sense of scale (Score 2) 142

When you are printing a 10nm wire into the silicon chip, you are not very far from doing it atom by atom as the wire is only like 50 atoms wide.

Perhaps, but at least with lithography you can do it across the entire wafer (or die) area in a single go. That's batch processing all the transistors at once, rather than serially processing them with AFM.

Silicon atoms are 0.2nm wide. We're getting into "why aren't you just directly pushing the atoms around with atomic force microscopy?" territory.

you probably could. However, for a processor with 10^9 transistors and perhaps a dozen layers, it gets pretty time-consuming to build it by pushing atoms around one at a time.

Comment Low Hanging Fruit (Score 4, Funny) 142

I am amused by this bit in the summary:

But as we approach 10nm, 7nm, and 5nm, the low-hanging fruit disappears

I'd say the low-hanging fruit disappeared a few decades ago. Continuing down the feature size curve has for many years required a whole slew of every-more-complicated tricks and techniques.

That said: yes, going forward is going to be increasingly difficult. You will eventually reach an insurmountable limit that no amount of trickery or technology will be able to overcome. I predict it'll be somewhere around the 0 nm process node.
