Turbo windmill, or Jet Wind Mill [JWM] / JWM is nephew, resp. spin off, of Spailboat, the stable sailing Speed Sail Craft.

The blades -rotors- are at their ends mantled by a ring. The ring is born within wheels in the housing. 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. Further on, one will see that windsurfing is done in the half wind sailing course and waves are swept by the wind, so that wave riding is falling with sailing half wind. Perfect.

High speed, directed perpendicular on the wind, leads also to the fact that a given sail area will be used optimally. And because cavitation, air bubbles around the swords, are restricting the windsurfers' speed, spailboat has wheels for swords. You, as reader, have to take it from here, because I can not force you to swallow dry food. Please, take one step at the time. To get started, you firstly need to understand that when a plate is placed flat -perpendicular- on the wind, there is maximum blockage of the wind by that plate. Next step. We imaginary move this plate with for instance 300 m/s in the direction flat on the wind. Now we'll see that the actual wind speed, S, that hits the blade is to be calculated by Pathagoras' law, S^2 =W^2+V^2, in where, V, is the speed of the blade perpendicular on the winds' direction and W is the wind speed. If now the original wind speed is very low, say, 1 m/s, than we might as well assume that the actual wind speed that hits the blade is still 300 m/s. In other words, 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.

I worked on stable sailing machines for twenty years now, because the capsizing and the catapulting with my catamaran scared the ........ out off me. Oh, I sailed from six years old, and won in 1988 the second biggest cat race in the world, together with my nephew, Ruud Goudriaan, who still is a class-A cat sailor. I went to college, and later to the technical university in Delft, and therefore I sold my cat, but continued windsurfing on cheap gear. However, windsurfing on old wave boards with old gear is still going much faster than the fastest cat. I kept on wondering why and when I figured it out [in 1994], I started to create a mechanically operated windsurf boat.

Sailing and windsurfing are very much like music, a well written song can be played live on stage over and over again, and every time this song improves itself. I can only ensure you, that the windsurf formula is an outstanding song, in the way to speak. Everything comes together, with as result that the windy circumstances on earth are perfect to use sails, wings, for making axles spin, as well on the oceans, by means of windsurfing -a combination of surfing and sailing stable half wind-, as on land, by means of using turbo windmills.

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 that windsurfing is sensation

This shown turbo windmill is spin off from the Spailboat.

A mantling ring around the blades holds the blades firmly in position. The ends of the blades are clipped in by this ring and the only freedom this ring has, is to turn. Above that, due to mantling around the blades with supporting construction, no mast is placed behind the blades. The blades do never pass a mast, so that the wind that leaves the blades is not disturbed anymore.

Conventional wind turbines use long masts to catch the wind at the highest possible vertical blade covering area as possible, because the conventional wind turbines are operating near living ground and over here is little wind -our ancestors could choose, and they chose to live here, instead of living at places with a lot of wind-. Long masts cause no particular problems in low wind speeds, however, in high winds, the masts tend to flip over and start to vibrate. To be exact, the vibrations in/at the masts do enforce the vibrations in the blades. Conventional wind turbines can not use high winds, because:
1: vibrations in the mast and tendency to flip over
2: vibrations in the blades, because of loose ends
3: vibrations of the blades, caused by passing the masts at the lowest point of the circular motion of the blades. It sounds like this: zzzzzzzzzzzzzzzzzzz , flope, zzzzzzzzzzzzzzzzzzzz, flope... et cetera, in where zzzzzzzzzzzz is the sound without passing the masts and flope is the sound while passing the mast.

The masts in old Dutch windmills are even wider, in order to house the big wooden cog wheels for the transmission, axles and specific industries in the "mast". The sails, or fabric, spread out over the rate construction at the beams of the blades, make an even bigger floping sound and a closer look learns that, during passing the mast, the sails are even coming loose from this rate construction. So, every time a blade passes the mast, the blade is loosing lift force. In the early days this constantly changing of the lift force in the wind mill beams was not a problem, because the mill making was done with wood and wood never tires.
Until 1800 A.D. we needed the windmills for powering our industries. Today, we need the wind again for, for instance, countering the raise of nuclear power, coal -, and gas, burning / using power plants for electricity, and to make an alternative for combustion engines.

Since the windsurfers, and later, the kite surfers, introduced a stable way of holding up sails, by holding the sails in such a way that the capsizing is no longer flipping the sailing composition over, even high winds can be used.

In a way it is trivial that exactly James Watt's steam machine triggered the industrial revolution, which resulted in global warming that increased the wind. So, we have more wind here and there [close to where we live and close to the arctic zones] and we can now use most of it.

The low wind speed regime can be used by conventional modern wind turbines and conventional modern sailing boats and high winds by turbo windmills and Spailboats. By using any kind of wind, until 12bft, any where on earth, we can say that the wind is to be used on demand, and his is exactly the reason of why the industrial revolution took off.

In 1773, when James improved the steam machine, we did not have carbon fibers, steel, composites and the windsurf formula, so that the steam machine did not have a competition.

En fin, by means of windsurfing high winds at oceans with spaiboats and using high winds by turbo windmills, the combination with conventional modern wind users for the low wind regime leads to new a competition for nuclear power plants et cetera. So the comparison of today is the combination of all wind converters, for making axles spin, with for instance the steam machine and his brothers -nuclear power plants, coal -, and gas, burning power plants-, which all still boil water in a big kettle, and combustion engines which are also still burning fossil fuels. Once again, we are on a certain track since the steammachine, which track provided us also combustion engines. Look: a cylinder in a combustion engine is a kind of kettle and the high pressure is caused by burning fuel in it to make axles spin. It is therefore, that the steam machine, nucluar power, combustion engines and powerplants are all brothers of eachother. I will fight these brothers now with the windsurf formula.

The windsurf formula implies that lift from the blades lines up with the reaction force and that the blades are hold steady and firm, so that high winds can be used.

The blades -rotors- in a turbo windmill are at their ends mantled by a ring. The ring is born within wheels in the housing. Because turbo wind mills use high winds, this mantle piece can be placed at/near the ground, so that there is no significant occurance of vibrating at the ends of the blades. The blade ends can not move with respect to the ring and the ring not with respect to the housi

6 wood rings with rocking post. Develops hand-eye coordination & shape recognition. Measures: 4.5" x 4.5" x 7.62". Ages: 18 Months and up.

Childhood just would not be complete without a set of stacking rings. Made by the classic toy maker, Schylling, this set is made of wood, painted in a palette of bright, nontoxic colors. Six rings fit in any order on the solid wood stand that rocks and sways like a buoy on the sea. This simple and familiar toy is also a tool for early education--learning colors, counting, coordination, and creativity. That's why it's been around for generations. With the knob secured on top of the post, the whole toy twirls like a roly-poly top. --Lynne Sampson
