Mighty Yar got it right, the US had embarked on a massive naval construction program in the early 1920's and was in a position to dictate the terms of the Washington Naval Arms treaty of 1922. If the other nations didn't agree, the US would continue building its fleet. Also helped that the Japanese diplomatic code had been broken, so Japan ended up agreeing to a reduced fleet. One consequence of the treaty was that two of the USN battle cruisers under construction were converted to carriers, and showing the USN that large carriers were more effective than small carriers.
The attack plans on Canada were drawn up as the US experience with WW1 led to vigorous opposition to any thought of engaging in another war in Europe. Opinion polls conducted in 1941 showed about 70% of the US opposed to involvement in Europe, and one result was that The US declared war on Germany on December 11th only after Germany declared war against the US on Dec 10.
The plan to take over the Soviet Embassy to search for nuclear devices wasn't delusional as the Soviets had smuggled in components for a nuclear weapon into the Washington DC embassy.
My uncle's 1950 GMC pickup had a very distinctive sucking sound from the air cleaner as the pedal was pushed towards the floorboards (and yes, this truck had floorboards).
3) Port to to multiple architectures (and OS's) to catch bugs not reported by the original build environment. This is one of the approaches OpenBSD uses to improve security and was quite common in the open source software world when ESR coined the phrase.
The OpenBSD team found one very long lasting (30+ years) bug in the legacy BSD code when the Sparc64 build barfed.
The USB and Firewire interface on the 10 year old J-Bus (UltraSparc IIIi) had memory management for the I/O interfaces as well as the CPU. The DMA from external interfaces could only access memory granted to it by the OS.
One of the most useful instances of social media and Googles apps was a series of postings on a San Diego Union Tribune discussion board related to the fires. The poster was embedding links to a Google Maps page with frequently updated fire perimeter along with reports of where the evacuation centers were being set up. It was very useful as my family and I were about an hour from needing to evacuate when the winds shifted.
"it becomes cooler than the surrounding air by around 9F (5C)"
Sorry, not possible, as per the first law of thermodynamics.
How in the hell do you think dew gets deposited on grass, cars, etc? Dew forms when the surface temperature drops below the dew point of the air, which cannot be any higher than the ambient air temperature.
FWIW, a problem from my engineering heat transfer course indicated that frost can form when the air temp is 9F/5C above freezing.
The microlayer is also highly reflective in the near infrared range as a not insignificant portion of the sun's radiation is in the near IR. It is the far IR that the material highly absorptive/emissive.
Michelson did a lot of work on measuring the speed of light, one of the last measurements he did involved a mile long vacuum chamber. As with many experimental physicists, he had to be an accomplished engineer as well in order to conduct his experiments.
Your point is correct about fixed links providing far more bandwidth that what can be provided by any kind of wireless link. The drone concept only make sense in places like the lightly populated areas of the US or similar countries where customers are too far apart to make wireline or fiber communications affordable. The low altitude with respect to satellites means that the link frequencies can be re-used more frequently.
I remember one of my brother's first issues (Apr? 1964) of Boy's Life having "Sunjammer" as the cover story. AC Clarke later expanded the story under the name "Wind from the Sun". FWIW, Boy's Life is one of the magazines digitized by Google Books and you can look up the issue in question.
Actually, you're the one who comes across as being ignorant.
Baseload generation is generation is considered to be the lowest incremental cost dispatchable power source. No form of generation has 100% up time, but a well run plant will have very little unscheduled down time. The variability of wind is a huge problem when wind generation becomes a significant portion of total generation at a give moment, requiring a large amount of spinning reserve to keep the grid stable.
FWIW, the limiting factor in power output of an AC generator is not conductor heating, rather it is the amount of power that can be generated without the generator pulling out of synchronism, especially under fault conditions.
What Edison invented was an incandescent light with a high enough resistance to make it possible to powered by a central station, along with the central station, a means of metering current, etc. Edison's work was mostly independent of Swan's.
While this book is not a Tesla biography, it does give a good picture of how Tesla fit in with the beginnings of the electric power industry. The book does give Tesla proper credit for the invention of poly-phase AC and the induction motor, but also points out that Stanley and Thomson were working on AC distribution before Tesla along with a lot of refinement on the induction motor being done by Benjamin Lamme.
It is the likes of Lamme and Steinmetz that are the unsung heroes of the electrical age.
When the Vatican decided to digitize their archives, they chose to store the mages in FITS format for pretty much the same reasons. One thing FITS doesn't address is preventing unauthorized access to the data.
In 1972, SAN to OAK was $24.50 on PSA with no restrictions. Equivalent fare on Southwest is ~$260, cheaper fares are available but come with restrictions.
The proposed reactor design sounds a bit like the EBR-II at INEL, formerly the National reactor test site, with the design also referred to as the Integral Fast Reactor. This program got shut down in the 1990's, though stories have been told about people who were sent out to Idaho to shut it down came back as converts to the cause.
With solar power, you get peak power and peak air conditioning load around the same time.
Not quite. Peak demand in California is between 6 to 7PM, peak solar production is approximately 12 noon. Peak load does not drop signficantly until well after sunset.
Decommissioning costs are still a lot less than it would cost to build the plant now. Letting the plant cool down for a few years makes the process simpler and safer, though the reactor vessel is going to be a challenge.
Something on the order of 97% of the atmosphere's mass is below 90,000'. 100km is an arbitrary value for the start of space, as the air at 100km is too thick to orbit and too thin to fly in (except dynamic soaring?). In imperial units, 100,000' seems to be the upper limit for flying and 100 miles is about the lower limit for orbiting.
The Perlan II sounds like it will handle like an unpowered U2 - where the planes ceiling will be defined by the "coffin corner" were the low speed stall (classic stall) approaches the high speed stall (Mach tuck from transonic airflow). Perhaps they will be using a more refined airfoil than the U2 to increase the Mach number for high speed stall.
IIRC, the pre-Perlan I sailplane altitude record of approx 47,000 feet was set sometime in the 1960's, surprising it took that long for someone to break that.

Very much what I was thinking. Get the protocols done right and who cares what processor or OS is in the device.

Having driven in Montana, that's very true for the eastern portion of the state.

Sounded like someone combined notes from a scientific lecture on the history of the earth with a "young earth" creationist's history of the earth.
And fiber has even more bandwidth than copper.

Hmmm, "Get them out by Friday".
A bit OT, but I was surprised to learn that "Attack of the Giant Hogweed" was mostly based on fact.
Electorate, schmectorate, decisions like this are based on who provides the most campaign donations.
