Peter resolved the impass by calling the health and safety group
Marvelously effective technique...I've actually had a facilities guy tell me he couldn't make a fix, then whisper in my ear to file a hazard report. OSHA may be a pain in the ass, but sometimes you can direct it to somebody else's ass.
The reason for those launchers was to get those ramjets to operational speed -- For a ramjet to work, it must have airflow. Without it, the engine just won't light.
No. You're right about ramjets, but the V-1 did not have one: it had a pulsejet, which started up perfectly well before the launch (though the thrust did increase with airspeed, as it does in other jet engines). It was several years after WW2 before any aircraft flew under ramjet power.
The V-1 needed the launch rail because it was a pilotless airplane: the rail kept it in a straight line until it had enough airspeed to for its wings to keep it airborne and for its crude autopilot to control it. Since the engine didn't have a lot of thrust, it also had a small solid-fuel rocket motor to accelerate it quickly up the track -- without that, the track would have to be much longer.
Of course, none of these have launched under their own power, yet.
And none of them are going to. One of the limitations of scramjets (and the earlier ramjets) is that they have no static thrust: they have to be hauling considerable ass before they'll even start up. They have to serve as auxiliary propulsion for a vehicle that is launched by something else.
No. Nixon appointed him to fill the office of Vice President, vacated by the resignation of Spiro Agnew who was under indictment for tax evasion, in 1973 as authorized by the 25th Amendment. Ford became President on Nixon's resignation in 1974, under Article II, Section 1, Clause 6.
Same reaction veterans had when they saw Will Smith in Independence Day playing a hotshot Marine fighter pilot in a dorky, ill-fitting uniform, put on wrong. I know they didn't have Defense Dept. support on that picture, but c'mon, you can walk into any bar in Oceanside with $100 in your hand and find a Marine who could help you with that.
Likewise James Coburn in the made-for-TV movie about the Sioux City DC-10 crash, wearing a full Nomex flame suit with ordinary first sergeant stripes sewn on it...if he worked near a real fire in that, he'd have been wearing his rank for life.
now that all the energy in the wind is being used to turn windmills
Try one-zillionth of hardly any percent of all the energy. As I mention elsewhere in the thread, one average thunderstorm develops tens of millions of kilowatts of wind power. Significant winds exist as high as twenty miles above the surface; the largest wind-powered generators are a few hundred feet. Draw your own conclusions.
What were the waves doing before that they're not doing anymore?
Turning mechanical energy into heat, again on a scarcely imaginable scale.
You do, if you have a two-car garage and one car. It's collapsible, and the lifting gas is expendable (as opposed to helium which is very expensive: helium ballons have to be kept full or emptied with expensive compressors).
who the hell will police the skies
The FAA. It's an aircraft, and they know precisely how to give you a ticket, thank you.
Surely hot Helium will have even more lifting power than regular helium.
Not bloody much. The lifting power of a balloon/blimp depends on the difference in density between the gas inside and the air outside. At standard sea-level temperature and pressure:
One liter of air weighs 1.3 grams.
One liter of helium weighs 0.18 grams.
Therefore, by Archimedes's Principle, a one-liter helium balloon will lift 1.3 - 0.18=1.12 grams.
One liter of helium at 200 degrees C (392 F) would weigh 0.11 grams, and it would lift 1.3 - 0.11=1.19 grams. So by heating the helium almost hot enough to melt nylon or burn paper, you'd get about a six percent improvement.
Imagine you're in a tight spot and your only communication tool is a radio with a dead mike or a flashlight, not an unimaginable situation. If you don't know Morse code, you're not only in trouble, you're likely to end up dead.
If it's a radio, it had better be ham-band capable; if it's a flashlight, you'd better be across the street from a Hamvention. Otherwise, good luck finding someone on the other end who knows Morse.
You can often see that effect in news coverage of a shooting. Some earwitness will say "I didn't think it was a gunshot because it didn't sound like one"...meaning it didn't sound like a movie gun.
Y'know, in my six years as an Air Force officer I held my fly shut with a zipper. The only references I ever saw to "Fastener, slide interlocking" came from civilian contemporaries making fun of my line of work. What was it like in your outfit?

And if such a time period had passed, all the sewer gases in your home would have long since been evacuated from the piping via your stack anyway.
Not if other toilets in the building are in use.

Oh, it's inefficient all right. Efficiency is for FedEx. Flying around with jet engines on your feet is for getting laid.

That much power...yeah. Like to generate ten or twenty gigawatts? Figure out a way to extract the energy output of one average thunderstorm.

Just apply the standard conversion factor:
1 home = (PI/e) * (1 VW Beetle) * (1 football field)

Ummm...OK...how would you feel about applying the same principle to Learjets?

If you and your family live anywhere near the launch site, or ride an airliner anywhere near it, you better damn well hope it does.
