Turbo windmill, the spinning version of spailboat.
Turbo windmill, or Jet Wind Mill [JWM] / JWM is nephew, resp. spin off, of Spailboat, the stable sailing Speed Sail Craft. Because turbo wind mills use high winds, this mantle piece can be placed at/near the ground, so that there is no significant vibrating occurring at the ends of the blades. In order to use high winds, the blades have to be hold firmly in place, leaving only the opportunity open for the blades to turn, or to move, perpendicular on the winds direction with as a consequence that Pythagoras' law comes in as foundation to calculate the angle of attack in the blades and the value of the speed. When an almost flat on the wind positioned blade is moving with very high speed, perpendicular on the original wind's direction, then the actual wind speed that hits the blades, comes almost from the front. A blade end of a windmill moves faster than that blade does near the center, so that blade ends are almost positioned flat on the wind. The same counts for windsurf sails, although the sails are hold almost flat on the wind, the actual wind flow that hits the sails is coming more or less from the front. This means that we want high speed, in order to get maximum conversion of a given sail area. High speed implies high lift forces, and therefore we need stable and strong configurations that hold the blades. The only limitations in using the high winds are now caused by preoccupation of the existing economy. For instance, the car industries, the airplane industries, wind turbine industries, sailing boats industries, et cetera, keep our engineers in hostage. If we only could stop the production and the developing of the car making, airplane making et cetera, for just one week, and bring this way all the engineers to one imaginary table then the formula of windsurfing is understood. Once the leading engineers understand the windsurf formula, then the building of the prototypes is a year away. Some floors of the car industries and the airplanes industries can make room for new production lines. And to make an even bigger example. When the second world war broke out, suddenly all floors of the car industries and airplane industries were making room for the production of tanks, jeeps, fighter planes, bombers et cetera. So, it is just a matter of priorities. By now, saving this planet is priority number one, and still all industries and all governments around the world do not see the windsurf formula. Even a child can see see that windsurfing is sensational. Just look at windsurfing from above. The waves make pipelines, and the only safe course in high winds falls parrallel with them. These pipelines lay, notably per definition, perpendicular on the wind's direction and windsurfing is always done half wind, so that the windsurfers automatically go as fast as possible and have a relatively save ride between the waves. All in all, the windsurf formula implies that a given sail area is optimally used, that the waves are helping in making speed, that the half wind course is always leading to gliding along with the waves, that windsurfing is therefore relatively safe, that a stable configuration is the condition to make big structures, so that former dangerous windy circumstances at open ocean are just perfect to move a significant amount of mass with high speed. The kinetic energy is measured by the formula: 1/2 times the mass of the composition times the square of the speed. This world is dying for energy. So, please, understand the windsurf formula and please make Spailboats for over water, and turbo wind mills for on land. I mean, did you ever see a professor, 60 years old, windsurfing on large waves with 10 bft at open sea? No, that is the problem. These kind of persons rule the world. Just go on the Internet, and see for yourself that the formula, for calculating the maximum sailing speed, is still only counting for non flying sailing boats. This means that they assume that the hull is still always dragging through water. For the cavitation speed they still assume always that a sword is not moving with respect to the hull. In Spailboats, on the other hand, the water cutting part of a sword does move along with respect to the hull, so that the speed of the hull and the speed of through water dragging sword have two different values. Here in Holland at the university of Delft, a leading professor -who works on his own sailing boat, off course-, once told me in person that no matter what kind of sailing boat, or windsurfer, it could never over top the 100km/hr barrier, because of cavitation around the swords. I came to him, at one of those appointments, to inform him about the new rigging, so that spailboats are almost flying above the water and to inform him about the reason -to overcome cavitation around the water cutting profile of the sword wheels- for using circle shaped spinning swords. So, I walked through his door, showed him my work, and in stead letting me talk about my work, he did not look1946 Indian
Article below copied from the online Juneau Empire newspaper Friday, May 16, 2008 Story last updated at 5/16/2008 - 10:47 am Riding tough By Eric Morrison | JUNEAU EMPIRE Juneau has more motorcycles per capita than most places in the country even though there are only 91 miles of road in the capital, said Sarah Asper-Smith, guest curator of a museum exhibit on biker culture. "That's pretty interesting," she said, adding there were 1,025 registered motorcycles in 2006 in Juneau. "That's something that runs through the exhibit, is why do we have so many motorcycles in town when you can't drive out of town? I think it's that sense of freedom that Alaskans have in common." "91 Miles to Ride: Juneau's Biker Culture" opens at the Juneau-Douglas City Museum on Sunday. The opening coincides with Juneau Museum Day, when the Alaska State Museum, Last Chance Mining Museum, St. Nicholas Russian Orthodox Church and the city museum will open from noon to 5 p.m. with free admission. Museum Director Jane Lindsey said the staff had discussed detailing Juneau's unique motorcycle culture for some time and decided to make it this year's summer exhibit. The exhibit will run through Sept. 27. "It's kind of got an appeal on a few different levels," she said. "These are our community members who have a passion for bikes, and this is what they do. And then, at the same time, you can see the bikes, which are kind of machine and art at its best." The exhibit highlights Juneau biker culture and groups with memorabilia and photographs, some of which date back to the 1930s, when there were a lot fewer roads. One of the pictures on display is of one of the earliest motorcycle clubs in town, which Wayne Fleek's parents were a part of. "It was about a dozen of them that formed the club back in the early '30s and they rode together on what little road we had around," he said. Also on display are four classic motorcycles, including a 1924 Henderson Inline IV on loan from Ed Squibb, a 1936 Harley-Davidson Knucklehead on loan from Steve "Razz" Rasmussen, a 1946 Indian Chief on loan from Don Howell, and a 9-foot-long 1975 customized chopper on loan from Craig "Oz" Orsborn. Rasmussen, a member of the Southeast Alaska Panhandlers Motorcycle Club, said he has been collecting, building and riding motorcycles for more than 40 years. "For me, it's just a continuing adventure," he said. "I've always liked old motorcycles. ... I've been in it so long I've seen it come and go in various circles of civilization." Rasmussen, who has ridden his 1936 Harley from Dawson City, Canada, to Tijuana, Mexico, over the years, said there is a strong biker culture in Juneau and Southeast Alaska. He said the Panhandlers club, which is celebrating its 30th anniversary this year, holds numerous events throughout the year, including a toy run for charity and an annual summer solstice party. "The weather never really bothers us," Rasmussen said. "We have various motorcycle rodeos and poker runs and events in other parts of Southeast." The Panhandlers club is prominently displayed in the exhibit, which also features the Southeast Alaska Tongass Chapter of H.O.G. (Harley Owners Group), Juneau Alaska Bikers Advocating Training and Education and other groups. "I've just always been fascinated by the fact that we live in a town that's not accessible by road, yet we have all these amazing bikers running around," Lindsey said. She said the Southeast Alaska Tongass Chapter of H.O.G is organizing a ride from the Safeway parking lot to the city museum at noon on Sunday. In her research for the exhibit, Asper-Smith said she learned there is a toughness that the capital's bikers possess. "Alaska attracts people who are looking for freedom, and with only 91 miles of road and very few days with dry weather, the motorcyclists in Juneau are pretty hardcore," she said. • Contact reporterEric Morrison at 523-2269 or firstname.lastname@example.org.
