  • Stop The Fisting
    By: Matthew McKernan | - In any military based system, the use of a fist is impractical and dangerous. Any system that advocates using a fist and is taught as self defense or in a military context should be re-examined as to its authenticity in real world situations.

    The reason that ko-ryu (old school) systems that were used to train samurai in hand to hand combat never used a fist and relied heavily on grappling and joint locks combined with limited edge of hand and heel of hand strikes when it came to ...

  • Residential Wind Devices: Which One Is Best Now?
    By: Roger Brown | - There are basically two kinds of residential wind systems out on the market today. The kind that spins horizontally and the kind that spins vertically. The type that spins horizontally is by far the most efficient. It has been around the longest and there are more in the field in any other type.

    The vertical type units have been around for a long time as well. However, they have not seen the popularity that the horizontal devices have because they are in a lot of cases at least 50% ...

  • Wind Generator Kits - Which Are The Downsides?
    By: Roger Brown | - There is no perfect system and wind turbine kits are not exempt from that maxim. Although they can be a great way to defray costs, they do have their downsides. Like anything else, there are upsides and downsides.

    Not to be a total downer, here are the upsides:

    Cut costs - not nearly as expensive as buying a fully ready to go turbine. This is because you are doing the assembly and usually the installation yourself. Shipping costs in to you are also less because t ...

  • The Magic Of Simplicity
    By: Iain Smith | - Albert Einstein said that everything should be made as simple as possible, but not one bit simpler. Now he wasn't a Glasgow personal trainer but this philosophy is as true for training program design and nutritional advice as it is for theoretical physics. Many overly complicated / technical exercise or diet plans that promise great health and happiness only exist to massage the ego of their creators. The more complicated something is the more likely it is to break down and not work. The mos ...

  • How To Generate Electricity With Magnetic Energy Generator For Home
    By: Kent Tran | - Generally, a magnetic power generator generates electricity using magnetic fields. Prior to explaining the physics behind how it actually generates electricity, you have to understand three things:
    - The strength of the magnets is what determines how much electricity can be generated by the magnetic power generator. In other words, if you have stronger magnets, you will produce more energy.
    - The generator will not power anything else until it powers itself. This takes away the conc ...

  • Options To Go With Wind Power
    By: Paul Meier | - Building a wind generator from scratch is not that difficult of a project. We will need a shop with basic power and hand tools, and some degree of dedication. Large wind generators of 2000 or more Watts and up are a major project needing very strong construction, but smaller ones in the 700-1000 Watt, 8-11 foot range can be construct fairly easily! In fact, we highly recommend that we tackle a smaller wind turbine before even thinking about constructing a large one. We'll need to be able to cut ...

  • Time Travel - Will It Ever Be Possible?
    By: Aaron Miller. | - Time travel is possibly the most interesting issue in all of physics. On the other hand, there's not much physicists can do about it; it is just not yet possible to do much work on the subject. Aside from a very few very specific experiments "around the edges," it isn't possible to investigate time the way physicists are able to examine most other aspects of this universe.

    You can find many puzzling issues in the study of time. Many physicists even claim that time is an illusion, tha ...

  • Sailing: Harnessing The Power Of Wind And Water
    By: CompleteSailor | - It is an absolutely clear and calm day, and the wind and water are moving in the same direction. This is not the most ideal situation for any sailor as there is not a good amount of energy to extract for movement. Energy is captured from the difference in motion, between the wind and water. The sailboat captures this energy by utilizing the sail(s) and the hull(s).

    The sailboat and wind usually have different directions, and this difference of motion is the relative or apparent wi ...

    There's a little more to the physics of sailing than the wind just pushing the boat along. Sailing boats move forward because of the flow of wind over the sails and the action of water resistance on the hull. Quite o ...

    They also believe that the Sun's influence for this warming is very small. We now know that the irradiance or "heat transfer" from the Sun to the Earth has varied relative little during recent decades. Therefore the conclusion that most scientists have done is that the resent warming must be man-made, this ...
