Fluoride, if used, should be applied to teeth by toothbrush or mouthwash. Whole-body application via drinking water is not beneficial and might be harmful.
There are 4 million miles of roads in the US, and about 600,000 police + sheriffs and deputies.
Most roads are 2 way. Want to describe how 1 policeman for each 13 miles of road will implement rolling roadblocks?
The manufacturer's website claims that the tail prop is meant to be the main source of propulsion; a clue to this is that the tail prop has 3 blades and the wingtip props are only 2 blades. I wouldn't be surprised if it could stay in the sky on only the tail prop.
Some more factors: the Beechcraft was introduced in 1982 and is based on an even older design, The airframe doesn't have the advantage of modern composite technology and computerized structural design, nor does it take advantage of more than 35 years of improvements in computerized aerodynamics. These things bring the new plane closer to feasibility.
A stationary engine can always be made more efficient than an airplane engine because of design tradeoffs between mass and efficiency. Same argument applies to mass and pollution. No need to consider nuclear for the first approximation. So: Ground fossil fuel engine runs generator to charge airplane batteries. The question then is how efficient is the generator and how efficient is the battery cycle? Batteries are heavier than the energy-equivalent amount of jet fuel, so it takes more weight in the electric plane to fly the same amount of cargo, and that lowers cargo-mile efficiency.
I'd guess that electric planes still lose this comparison, but it may be closer than you think.
Domestic electricity in most of the US is not cheaper than road fuel; if it were electric resistance heating would dominate instead of heating oil, natural gas, and propane. Typically, domestic electricity is not quite twice as expensive as liquid fuels.
Electrolytic capacitor lifetime estimates are based on ambient temperature and rms ripple current. Keep them cool and use caps rated for much higher current than is actually applied, and they can last a long time.
Some manufacturers of better dress shirts specify neck size and sleeve length. Some manufacture normal and thin varieties. You also have the option of buying an oversize shirt and modifying it yourself for a better fit, Or buy a custom tailored shirt.
The 2 main causes of death in civilized countries, cardiovascular disease and cancer, can to a large extent be eliminated, delayed, or at least reduced as a risk by exercise, diet, and supplements that are widely available. Add to that feedback from occasional blood tests, and the costs are a nuisance but not an impossibility for the middle class. Figure $3000 / year for supplements and tests at age 60, less if you're younger because your body isn't failing to properly process nutrients yet.
Appearance tends to echo general health, and the same nutrients that prevent heart disease and cancer promote general health and the appearance of youth. Looking 20 at 100 isn't the situation yet, but it's not far off from what is possible at a reasonable price.
Of course, there are many things we don't have a handle on yet, like male pattern baldness. But dramatically extended life for many people who are willing to put in the effort is here today.
The taller a person is, the more brain damage he incurs if he falls and hits his head. I'm 6'1" and once knocked myself unconscious slipping on ice and falling.

981 billion divided by 325 million is not 3.

Most of the salt is spread by government entities.
Generals Washington, Grant, and Eisenhower would like a word with you.

Composites can be shredded to make insulation.
VTOL takes a lot more power than conventional fixed-wing takeoff.
Exponentially - that word does not mean what you think it means.

Do the math and see what speed you could maintain on a solar powered aircraft. You'll wish you had oars.
What sort of plane do you think flies between Denver Colorado and Kearney, Nebraska, and then on to Grand Island and Lincoln?
Propeller planes above 450 mph have been around for 70 years, although they tend to be specialty craft. https://en.wikipedia.org/wiki/Fastest_propeller-driven_aircraft
What part of "closer" do you not understand?

This is how you attract people to your side, by insulting them?
Too late. They already are genetically superior.
That only works as long as you don't have idiots or villains in control of the U.S. government. Consider the Panama Canal.

Eventually, many favorable edits will spread through most of humanity. EVERYONE benefits.
Some degree of webbing does happen occasionally. It's generally considered a birth defect and treated surgically.
