Acoustic Transducers for High Altitude Balloon Control
Using acoustic transducers it maybe possible to create a small region of thicker air underneath a blimp and use that patch as a platform of air to float on while blowing ever so slightly low pressure air underneath the blimp like a hover craft. Although this idea sounds like a long shot it can be done by use of a screen, which shoots the directed frequency waves into the waves created by the acoustic transducers. In fact it maybe possible to place the acoustic transducers on poles, which hang down from the blimp and right below that place a screen which rolls out below the blimp. The wave interference once airborne allow the use the thicker air which is made thru alignment of the air molecules as resistance for the low pressure air blown against it. Any thicker air, which is pushed down or away from the blimp as it moves will freely flow thru the large holes in the screen. Why bother to make a blimp float easier? Because you need less volume of lighter than air gas to float the blimp. Meaning your aircraft can be smaller and more maneuverable. Also it allows for more aerodynamic options with regards to shape thus higher airspeeds can be obtained.

Mini Robots Grid Meteorite Search We need very much to study meteorites more, but we need more sampling to get this done. One way to do this is to go out hunting for meteorites. This is much easier said than done. But perhaps using some current technology it will not be quite so hard. For instance AFF Automated flight following systems has been used for more than a decade now. It uses GPS tracking by satellite to guide aerial fire fighting aircraft into the drop zone to let loose of their fire retardant. This is especially important when you cannot see and know that there is no ILS Instrument Landing System to guide you in. Creating Artificial Time in a Vacuum With Pulsed Lasers Keying off a very interesting concept confined within Static Quantum Theory and looking for the edge of time or the end of energy or the Quantum Borderline or virtual boarder of nothing. One might use the idea of pulsed lasers created in a defined confined area of a vacuum to create a singularity of a pulsed laser, whose immediate disruption pulses of the singularity which would follow would reach the end of the confinement area faster than the light which would in fact be created and then this traveling disruption would trigger another pulsed laser reciprocal event on the far side of the confinement whose pulsed laser would send it's disruption of the event to occur to the original point of the first singularity of the original laser or starting point, which would trigger the turning off of the first laser before it created the event of singularity or light. The Bermuda Triangle and Antarctica The art or science of metallurgy is vital to the social structures surrounding all esoteric beliefs. They are the most tangible items of the cosmic soup that are possibly drawn to certain Earth Energy Grid locations as we shall see. The shamans who gathered meteorite material to fashion tools and weapons as well as for the use of the metals and spirits thereof became great aristocrats, as their family or heritage and legends grew. Genghis Khan (Temujin) is from such a family and most of the early aristocrats were either adept (like the House of David and Solomon) themselves or worked closely with these artisans who we could call alchemists, as Mircae Eliade does in his 'The Forge and The Crucible'. When the Spanish arrived in Mayan lands they asked the Aztecs and others where their knives came from, they also found a meteorite at the venerated apex of the Cholula pyramid. They pointed to the heavens and the Spanish reports call this paganism. When this use of metals began is anyone's guess. Many Sci Fi writers have discussed Earthquake predictions Cal Tech along with the Universities in Japan are on the leading edge of this new technology and it is quickly becoming a reality. Soon we will know months in advance of an expected quake and the precise time maybe known hours or minutes before it actually comes. Arthur C. Clarke discussed early Earthquake warnings in CA, in a couple of short essays and stories and then again in a two of his most famous novels. If you will recall the book, "Richter 10;" in this book they could predict the Earthquakes months in advance. Ceramic Coatings Inside Plastic Water Bottles? A new report claims Water in plastic bottles could pose a problem, and of course why wouldn't it? This is a much debated topic indeed, so please read. Big Bang or Lots of Big Fire Crackers? There are many who talk about the Big Bang Theory. Although no one can be sure what went bang? Steven Hawking suggests it does not matter what went bang, because we will never know, so let's think on things we can know. Interesting comments indeed, others suggest you cannot have a big bang without having something that went bang. Therefore they say the big bang theory is hogwash. Still others say God created it all? Yet the critics of that concept say; "Well who created God then?" What is Science? Students often ask; "What exactly is science?" Professors explain by discussing theories, proofs, laws of physics, observations, duplication of results, etc.. Professors often pull rank on students when they argue a point with the professor on extending the professors definition of science. When this occurs the professor indicates to the student; "You obviously do not know what science is" they quickly tell the student. How Did DNA Testing Children Begin? The landmark immigration case Sarbah vs. Home Office (1985) was the first to use DNA testing to prove a mother-son relationship between Christiana Sarbah and her son Andrew. Mississippi River Mouth Debris Jetting Using Acoustic Transducers The Mighty Mississippi is backing up and causing flooding issues due to over growth build up at its river mouth. This is dangerous because that region is already so close to sea level. In fact much of the City of New Orleans is 12-feet under sea level and protected by a man-made seawall. If we could clear the path to the ocean and watch the fertilizer run off from up river, we may save ourselves a lot of future outlays in the event of a sea wall breach. The current estimate is 155 Billion Dollars in FEMA aid if a large category Hurricane makes a direct land hit at New Orleans, Louisiana. Will Clones Run the World? In the US it appears that we have decided that "life is not for sale" and that the cloning debate is over and our scientists are forbidden by law from attempting to clone humans. In other countries they are currently trying and will most likely continue to try until they get it right. Will those countries which move forward in human cloning be able to force their will on free markets and rise to power faster since they will have the abilities of entangled brains and abilities of basic thought transfer? Such skills will be quite an advantage indeed. Will such countries have stronger corporations and create wealth faster than our corporations? Will the multi-national conglomeration corporations of the World continue to be so large it will not be significant until way into the future? Will more countries become run completely by super dynasty clone families, will they run the world? Three Types of Telescopes - What are the Advantages Refractors, Newtonian reflectors and Catadioptrics are the three main types of telescopes. All these different types have the same purpose, but each telescope design does it differently. Collecting light and bringing it to point of focus so it can be magnified and examined with an eyepiece is their goal. June 2005: Weather Forecasts for Vacationers If Johannes Kepler, the renowned 17th century astronomer and discoverer of the planetary laws of motion, could speak from the heavenlies, he might have a few words of wisdom to share with the National Weather Service. Although Kepler's name is not normally associated with meteorology, he was quite the weather forecaster in his day. His first claim to fame, by the way, was not due to his discovery of those planetary laws, but because of his accurate long-range weather forecast of the severe winter that put Styermark, Germany on ice in 1593. Launching 400 UAVs from a Transport Plane How to launch hundreds of UAVs for an autonomous mission from a transport plane. As we watched the MOAB parachute bomb drop out of a C-130 onto the desert and above the tunnels below into Afghanistan, it left the world in awe. Now then this parachute concept has another idea. Launching UAVs, hundreds of them in swarms of 25 to 50, to overwhelm the opponent. Space Travel - Human Innate Bonding to ELF ? Extremely Low Frequencies of Planet Earth Human innate bonding to ELF ? Extremely Low Frequencies of planet Earth will be a problem in space travel for the future. How do we know this? We know because insanity seems to very often coincide with mental illness. And the human beings which travel great distances will be subjected to many other problems such as; radiation, calcium breakdown, Closter phobia, space weather, loneliness, food rationing, lack of sex, stir craziness, etc. That Dust on Your Car May Soon Be Smarter Than You Think? Here is a thought to get this topic started. A thought on a smart dust design. The smart dust will have to be able to stay airborne for long eriods of time. I was contemplating cleaning off a car which actually had hightech SmartDust on it? God made dirt on the first day right? Well, yes as the story goes he made the Heavens and the Earth and he made that out of dirt. So as man becomes God, he will need to make first things first. So perhaps the thought of making dust is actually a very noble step for mankind indeed. Environmental Eco-Terrorists Must Be Stopped Eco-terrorists assume some how they are helping the environment, by causing news worthy events and starting forest fires or burning down developments. Yet in doing so they cause air pollution and kill animals. This type of energy they are exhibiting causing harm is bad. This level of high energy could be good energy and used in positive ways. America needs high energy from people to get stuff done and maintain the flows of our civilization, but these eco-terrorists are so misguided that it is upsetting the balance of things. They are doing more than terrorizing, more than polluting, they are tearing apart the fiber of America and causing a rift between smart environmental considerations and conservative movement. They must be stopped. Electromagnetism, The Universe, And You An electric current produces a magnetic field. This is the principle of the electric motor - varying electric currents moving along wires make magnets with drive shafts spin around in circles. UAV Mini - Torpedo Bombers for Eliminating Hydro Cushioned Water Craft UAVs can carry cargo, some of the very tiny UAV units can hold up to 11 lbs. Which is not much, however. A one-way UAV could fly over a river that is used for transporting troops and supplies by your enemy via hydro-craft, which can hover over regular water. These mines would normally be set by Navy Seals, by using small robotic units we can save the risk of life unless it is totally necessary. Crop Circles and Genetic Knowledge The crop circle enigma is not always a hoax. I am not able to see how someone could do a massive design overnight in the cases where the plants have their stems broken from within. Yes, that is the case in what I consider the real crop circles. The wheat or other plants have the stalk exploded from within and the stalks can be bent at a distance up the stalk which would not happen if the use of weighty rollers was applied to them. Thus we are able to speculate many things but I see no reason for it to be aliens or at least not a visit in physical form by extra-terrestrials. Troubleshooting Pump Problems the Easy Way In any problem analysis, we have to specify the problem, check whether there is any deviation from the normal condition, identify the possible causes, evaluate the possible causes and then confirm the true cause.
