  1. Well, the way I see it, is that the bigger the wheels on the car, the more blade surface you can fit on it, and the greater thrust you will have. I would suggest 19-inch wheels inside larger 20-inch wheels, which would be attached to the tires. The car might have to be jet-propelled like on an airplane. Actually, I don't really know how thrust is generated on an airplane, so I'm going to search for it on the Internet as soon as I finish this post. Cars that fly will probably have to be computer-controlled, and may have to fly inside different flyways (similar to highways) to avoid collisions. The flying car is just more efficient than a regular car, which has to stay on the ground and travel on roads, while the flying car can fly directly from point A to point B. You could fly it directly into a lake and then activate the boat function, which would just be for fun in your free time. Going underwater would also be for fun, and you could observe many underwater life-forms. The boat and underwater functions could also be computer-controlled. If you just wanted the car for efficiency, you could just have the flying car option and leave out the boat and underwater travel options. That's fairly simple, isn't it?
  2. A knife, fork and spoon are usually used for eating different types of food, so we are better off if they're separate. Usually, only a fork and knife are needed to eat food. So, about the car: If you don't have a lot of money, you could just buy the car. If you had a somewhat large amount of money, you could add the skycar feature. If you had a large quantity of money, you could add the boat feature, and if you were rich, you could finally add the underwater feature. There's nowhere in the world you couldn't go in such a car!
  3. Yes, I realized the same thing. How about using 18-inch wheels, and having the last 3 inches attached to the tire, while the inner 15 inches would rotate very quickly? If the car could be made waterproof (the Japanese are good at this), the car could go underwater, which would be a 4th mode of transportation. The 4 wheels would be vertical, but at right angles to the direction of travel. The car could be called a quadcar, 4car, or supercar. I'm not an engineer, but I'm very creative. Thank you for replying.
  4. I have a really neat idea. Engineers should be able to build a car that travels on land, air and sea. The main method of locomotion would be in the wheels. For travel on land, the wheels would be vertical, and travel on roads, which of course is possible. They are just called cars, or possibly landcars. For travel through the air, the wheels would slowly turn to a horizontal position, and start rotating within the tires. The wheels would have small wings in them, which would provide lift when rotated. The car could take off and land vertically. The cars would be called aircars, skycars, or flying cars. For travel on the sea or lakes, the car would be driven a short distance into the water, then the wheels would turn to a 45 degree angle, and start rotating within the tires. The small wings on the wheels would propel the water backward, thus pushing the car forward, as in a motorboat. The cars would be called seacars or watercars. Of course, all 3 functions could be used in the same car. I'm not sure what size the wheels should be: I was thinking 15-inch. The resulting car would be called a 3car or supercar, or something else. I think this type of car could be built. Does anybody else have any thoughts on the matter?
  5. How can a person use a computer to design a computer better than itself? Or does it need a person to provide creativity?
  6. Goto Wikipedia.org, then search for "tau lepton". Look under History, and there it is. I hope this satisfies you.
  7. Thank you for your help. Did you know that you look almost like Stan Laurel of the Laurel and Hardy famous comedy duo? Just look up specific subatomic particles, for instance muon, kaon, tau lepton.
  8. By "we", I mean the scientific community. I got all of my facts from Wikipedia.org.
  9. How about using a negative ion in place of the electron? Would that work?
  10. I was reading about muon-catalyzed cold fusion, and I thought if muons don't work in cold fusion maybe some other negative subatomic particles would. Muons decay after 2.2 x 10 -6 s, which is too short for cold fusion. Kaons (K-): Charge-parity violation, which generates the matter-antimatter asymmetry of the universe, was discovered in the kaon system in 1964. The lifetime of the kaon is 1.238 x 10 -8 s, too short for cold fusion. Tau lepton: Has a lifetime of 2.9 x 10 -13 s, too short to be considered for cold fusion. We have discovered 64 events of the form e+ + e- > e+- + muon-+ + at least 2 undetected particles for which we have no conventional explanation. In total, the tau lepton will decay hadronically approximately 64.79% of the time. These particles decay in too short a time. There may be some other negatively charged subatomic particles that will decay in a longer time and can substitute for the electron to cause cold fusion.
  11. I have devised a photonic motor just in case people switch from electricity to light. It would work like a radiometer, except it would not need a vacuum. It would have about 6 vanes, which would be colored black. A laser would fire a laser beam at the vanes, which would absorb the photons and cause the vanes to rotate clockwise. For a faster speed, the vanes could be colored white, which when struck by a laser beam, would reflect the light back. When the laser light hits the vanes, the vanes would absorb the momentum of the light and be pushed clockwise. When the light is reflected, the reaction with the vane would push the vane clockwise, making it turn twice as fast as the motor with the black vanes. That's all I have to say on the subject.
  12. Fusion may occur if you have deuterium (an isotope of hydrogen with 1 proton and 1 neutron atoms colliding at speeds near the speed of light from opposite directions in a cyclotron (a circular particle accelerator). Here are the equations: \[ \text {Kinetic Energy} E_{k1}=\frac {1}{2}mv^2, E_{k2}=\frac{1}{2}mv^2\\ \text {Since the atoms are travelling in opposite directions, total energy} E_T=E_{k1}+E_{k2}\\ =\frac{1}{2}mv^2+\frac{1}{2}mv^2=mv^2.\\ \text{If } v \rightarrow c, \text{then total energy } E=mc^2,\\ \text{which implies that matter is being converted into energy.}\\ \text{Sorry that everything is centered. I couldn't figure out how to end or add a line.} \]
  13. That makes sense, Swansont. Thank you for your reply. If not the spiral pattern, they could be using a zigzag pattern - they could go from left to right down a row of flowers, then right to left down the next row of flowers, left to right down the next row of flowers, etc. A good way to find out what pattern they are using is to plot their paths on polar graph paper, which uses (r,theta) notation, where r is the radius and theta is the angle.
  14. Bees are probably using a simple algorithm to solve the travelling salesman problem. We know that when bees get back to the hive after discovering a new group of flowers, they do a little dance. The length of the dance represents the distance to the group of flowers, and the direction they are pointing indicates the direction to the group of flowers. The bees could be using a spiral pattern to find the flowers. They would start at the middle group of flowers, and work their way outwards in a spiral pattern. That's just a guess. They could be using some other algorithm.
  15. Well, we know that E=hf, so the greater the frequency, the greater the energy. If you wanted to stay within the visible spectrum, you would chose ultraviolet light. Beyond that, there is X-rays and gamma rays, but I don't know if the fiber optic cable could withstand such high energies, or if the cable could contain these types of rays. Instead of using solar cells, which have very low efficiency, to change light into electricity, the light could bounce off mirrors arranged at 45 degree angles, and the light could circulate around a square made up of 4 of these mirrors, which would constitute a photonic capacitor. The light could be channeled into a photonic pumped laser which would use 2 different gases to keep the laser operating continuously. The laser beam could be modified for use in monitors and TV sets, which would use part of the laser beam for power.
