A propeller and a generator is currently mass produced, cheap and efficient. In the setup the fan probably draws 300W, and the belt generates 1W, or 0.3% efficiency. What a joke.
To clarify (2): The power of a supernova is 200x this event(0.5%), and in addition it lasts for weeks, so total energy of a supernova is maybe 7 orders of magnitude more.
Just voted in Norway. All paper and apparently manual counting. This surprised me since USA have used punch cards for at least a quarter century, and now is mostly electronic.
And BTW, a lot of cheating and errors with the old way, so maybe we should not demand perfection for the electronic systems.
9.4% is probably way off, but here are some conversions/comparisons anyway: 868 billion kilowatt-hours per year = 10^11W=100GW Space shuttle liftoff: 100GW
It's not a bug, it's a feature. Like OOXML, where all MS defects had to be implemented as features by other developers. MS has defined this MUL as a feature. It is now up to us to update textbooks and other spreadsheets with the same feature.
To conserve momentum (and other) at least two photons are released in opposite direction when the two particles annihilate each other. If this is part of a gamma ray laser, you will have two rays: One aimed at your enemy, one in your face, and a mirror will probably not work at 0.5MeV.
Just do this: 1. Register the name, company and address and other info (IP, MAC? etc0
2. Display this licensee information every time the program boots up.
3. Write a standard EULA that allows use on 1 CPU If someone wants to pirate the SW, they will just have to live with the Owners name and company. You will get no corporate piracy. Only limited individual distribution.
A blast furnace is a metallurgical furnace generally used to produce iron. It operates between 2000 C to 2300 C (3600F to 4200F). (Irons melting point is 1538 C or 2800 F).
Use google sky. (Included in latest version of Google earth) Spend the money on a big monitor or even a projector.
I have a projector onto the (high) ceiling in my house, and I lay down on the floor with my kids. We look up and can look through the eyes of the best scopes in the solar system.
This is not said lightly. I spent a lot of nights on observatories on mountaintop in desolate areas, and took a lot of pictures of planets and moons using 14" refractors and 40" reflectors. The result is very poor compared to hubble and keck.
I even built my own scope. Just the mount was $2000 in parts, and months of work. It is beautiful, and could probably support a loaded cement truck. Of course, with a 20" mirror, even the rings of Saturn are unclear and fuzzy compared to Cassini's.

A team at Cisco decided to build a big router. This was all the engineers wet dream, and management didn't really think it was any need for anything this big. But since this was in the middle of the.com boom, the team got the green light. Engineering called it the "Big Fucking Router" or BFR, and marketing called it "Big Fast Router".
The 12000 or the GSR was introduced in 1996(?) it was wildly successful, and generated 1 billion dollars in sales the first year, and went up from there.
As a result, when the engineers introduced their next wet dream, the HFR or "Huge Fucking Router", the argument was "We can build it faster and bigger than anyone will need, and by the time it is introduced it will hit the market window perfect, and with great success"
The HFR, or CRS-1 is a 100Tbps router. (500 developers for 4 years or $500M).
Only problem: the boom is over, and few are buying. Solution: Create doomsday scenario that only the HFR can cure.
Just some multiplication: A Youtube stream is 100kbps, so the HFR can handle a billion of these. That is more than there are internet users in the world.
How about also realizing that "Round earth" and "flat earth" are scientific theories and not scientific fact. The biggest problem I see in science today is failing to properly delineate between fact and theory.
It should further be obvious to anybody that the earth in fact is flat, and that the heavenly bodies all rotate around us.
Can anybody *feel* the spinning of the earth? I did not think so, therefor this is a fact.
We should define "fact" as undisputed theory, so by definition, since I dispute that the earth is round, it is not a fact but a theory.
The force on a foamball or snowball will be the same. The foamball will impact with a higher speed, but the iceball will spend more time in the airstream, gaining much more momentum, so what is worse? Since v=2as, F=ra, E=1/2mv^2 where v is impact velocity, a is acceleration and s is distance it is falling before impacting. F is aerodynamic force and equals density r, times acceleration (For a unit size piece). E is impact energy. Solving for Energy E=2rF^2s^2. Only density is a variable. The rest is constant, so we revrite as
Impact energy E=kr, where k is a constant, and r is density. So ice is worse than foam.
Lets solve this the old fashioned way with a snowball fight. Everyone on the 'foam is the cause' over to the left tile castle, and start throwing the foam balls. Everyone on the 'ice is the cause' over to the right tile castle, and start throwing the snow balls.
Market captialization of the whole company is $9M. Maybe all/. readers should pony up $9, and buy the whole company.
Then we can have a board discussion here on/., and make Darl C. McBride implement our decisions and post press releases.
New press releases: -SCO has hired Dogbert, and McBride's new office will be the cardboard box the printer came in. -SCO opens a new office in Elbonia, and all in management will move there.

4. Use magnetic field outside plasma ball to contain radiation
This seems like the exact reason why basic physics should be mandatory in schools. Dear God. How exactly would a magnetic field contain neutral photons ? They will generate zero flux and will not interact with the field at all.
Please reread parent post. Note: 1 ton/m^2 of mostly Nitrogen *and* magnetic field to protect people. Life on earth has pretty much evolved around surviving radiation not caught by this protection. The physics is sound. 1. Atmosphere is opaque to photons with ionizing energy. 2. Neutrons are slowed down very well. 3. Charged particles are caught by magnetic field
Design parameters for fusion reactor: 1. Contain a plasma ball with high density for fusion reaction. Ball is much better than doughnut if you just can figure out a way to keep the plasma together. 2. Make a wall that is far enough away to not melt from this plasma ball to absorb heat/radiation to make power, and keep it close enough to get high enough energy density on its face. 3. Make the wall 1 ton/m^2 to protect the people outside 4. Use magnetic field outside plasma ball to contain radiation.
This seems like a tall order, and it is, but consider the sun/earth: 1. Gravity works great compared to magnetism. 2. Well, here on the earth, it is 1kW/m^2. That is much higher than the energy consumption in most cities. Should be good. 3. Our atmosphere stupid. 4. The earth again has a great magnetic field that protects us pretty well.

...I failed two out of three years of math classes...
What part of high school math did you not understand at the time? Addition with carry or drawing circles?
I would suggest to you that there is no hope for you.
If you failed because you were sick or similar, and you are now OK, you should be able to cover the high school curriculum with a weekend course.
MIT uses "Calculus with Analytic Geometry, by Simmons" for their freshman class 18.01 for students with no calculus in highschool; Read it!

They use elmers washable paper glue. I built an aircraft, and can assure you that this is not a good choice for an aircraft.
The structural parts altogether to be more for a movie prop than anything flying.

(10exp33 Joules), equivalent to a large (2000MW) power station running for two billion billion years.'"
This is basically
1. 1 sun-month (power of the sun 4x10^26W for a month), or
2. 0.5% of a supernova

Since the snowball fight is not sufficient to convince you, as it was to my 5 year old son, I'll do the physics:
s ics
From http://spaceflight1.nasa.gov/shuttle/reference/ba
It actually goes supersonic at about A1=8500 m, and hypersonic at A2=50km altitude. aerodynamic load at A2 is similar to 140km/hr at sea level.

Photons have 0 "rest" mass, but remember:
E=mc^2 and for a photon, E=hc/l, 'l' is wavelenght and h is planck's constant, so
photon mass, m=h/(lc)
