For commuter craft air traffic control I have always thought a good system would be to just assign different altitudes for different directions of travel. (I.E. 9,500 for S by SW, for example)
For a good VTOL craft, there is an interesting concept that I have heard of. You could have a flying car (a la Blade Runner) based on Active Glow Discharge Plasma panels.
This would work by having glow discharges between many paralell wires. This would of course cause an ordinary ion drift, producing minimal propulsion. But if you put a magnetic field between each wire, you cause the ions to take a curved path around the field. This greatly speeds things up.
Through this method, (being developed by NASA) you can accelerate air a couple hundred meters per second. The up side of this is that the glow discharge panels are very simple and would be cheaper than helicopters. So, basically, you could have a small gas turbine power supply to power the panels. The craft could actually lift off vertically. Then, during horizontal flight, wings could be extended for greater efficiency.

Even if the statistics of per mile or per hour risks were similar or better, I doubt that it would stay that way if people are using it for regular transport.
The statistics for non-comercial air travel are significantly worse than cars.
This is due to private pilot's inexperience, flying in more risky conditions than a 777 would fly in, less reliable aircraft, etc.
And it was the aluminum paint on the fabric that caught FIRE, not the hydrogen. Hydrogen EXPLODES with a nearly invisible blue light.
I have done extensive, um, experiments with garbage bags full of hydrogen. (Put lye, al foil, water in gas can attached to hose.)
To explode, hydrogen needs a lot of oxygen. To make a bag full of hydrogen explode, you have to introduce quite a bit of air into it. (Enough air to render the bag unable to float) If you don't put any extra air in, the hydrogen just burns along the outside of the bag, and it actually takes a few seconds for all of the hydrogen to be consumed.
The Hindenburg did not explode because of the hydrogen. (A spark could not catch the hydrogen on fire on the inside. There is no oxygen) A spark must have caught the fabric on fire, which was doped with dangerous compounds like saltpeter. (Which actually rendered the skin very, very flammable).
So, it was mostly the skin catching on fire, which was aided by the heat of the hydrogen combustion. Also, those huge yellow flames you see? That's the skin burning. Like the previous poster said, hydrogen burns with a nearly invisible flame.
BZZZZT. Wrong. one, the materials used are going to be heavy.. carbon nanotubes will have weight comparable to diamonds..
BZZZZT!! Wrong. This ribbon is lighter than tissue paper. I don't care about the 1 k rotational velocity at all. It would be slowed down by air drag to just a few miles an hour. Throw a piece of tissue paper out of the window of a fighter in a dive at mach 2. Will the tissue paper stike the ground at Mach 2 and kill someone? No. Of course not. Neither would this.
If you're talking about "rubbing alcohol," that's not ethanol...it's usually isopropanol.
It's usually isopropanol. But often, it is denatured ethanol. Rubbing alcohol is isopropanol. Denatured ethanol is usually just labeled "Denatured Alcohol." I've got a bottle of it in my bathroom right now.
I hope that some one comes up with a smalll enough package that it can be designed to fit into the variouse packaging design that diffrent Laptop makers have for there batteries.
Just use palladium hydrogen storage for the fuel cells. Palladium has an interesting property of being able to absorb about 800 times it's volume of hydrogen. It is experimentally being used for fuel cell cars.
Palladium is quite expensive, however I don't think you would need very much for a laptop fuel cell.
However, if tehy do not last long, and users are having to swap them out constantly, doesn't that pose a fire hazard? (having 2 fuel cells per lap top toting passenger?)
When you think about it, the methanol is encapsulated and is a fairly small amount (50 mL maybe?)
When you order your shot of scotch on the plane, you have a flammable liquid which is not encapsulated at all, and is slightly more volatile than methanol.
And also the normal components inside of your computer are very carcinogenic, the recycled air in the cabin can be harmful, etc, etc.
A mildly poisonous (compared to, for example, household bleach) chemical like methanol won't do you any harm in a sealed container in quantities of less than an ounce, as in a laptop fuel cell.
May I also remind you that the ethanol you buy at the store is denatured with methanol anyway. You probably already have a good amout of this toxic stuff already sitting in your medicine cabinet. We deal with extremely toxic stuff all the time. For example, aspirin is much more toxic than methanol. Try eating 1 cup of aspirin. You'd die of liver failure.
We can't just let all of these irrational fears get in the way of advancement.
My resistance heater (which is very inneficient compared to the heat pump) goes on only on the very coldest nights during the winter, like when it gets below zero. The resistance heater eats up gigantic amounts of power. When going full blast, it can use 50 KW. We also have a fairly large house.
We know that this policy will raise the demand for fetal tissue, even that gained from murdered children,
Murdered children!!?? Come on, let's be resonable.
High cost of humanity? Come on, it's clumps of several hundred undifferentiated cells. Not a human at all.
The "potential human life" argument is ridiculous. If one thinks it's murder to take an embryo because it has the potential for human life, than isn't it a moral tragedy that you denied your sperm (or eggs) the potential for human life because you didn't get pregnant or impregnate someone the moment you hit puberty?
Thinking about the potential for human life is ridiculous. I only care about human life, from the onset of a conscious human mind.

900 kw of heat is a lot, but not a totally monstrous amount. Maybe the heat created by perhaps 20 full-house heaters going FULL BLAST. (50 kw a heater.)
Those are real tesla coils. But they are not powering the computer. I see a picture of what looks like 1 million volt teslas out on somebody's lawn. (Yes, big coils like that really do shoot those huge sparks)
I just can't imagine how this would power a computer. Most computer circuits run on low voltage. Just a few volts. I can't imagine how a huge tesla coil wouldn't fry a processor considering unnoticable low current 1,000 volt static discharges can cause a mobo to fail.
This guy is full of shit. I just see a picture of the coils out on a lawn and then some pictures of a computer. Powering a computer with a tesla coil is a good way to make liquid silicon.

Read the faq on the site. It states that it is very light.
At any rate, this is as thin as tissue paper. Even lead in the thickness of tissue paper is quite light. And this isn't nearly as dense as lead.
