I posted some things about this subject some time ago and it is again interesting me. Thought it might be interesting to someone else.



The Amazing Glider And Energy

An efficient 1000 lb glider can be towed on a level path in thin air at 60 mph using only a quite light fishing line, as it only places 16.666 lbs of pull on the tow line, and which also calculates out to only 2.666 hp of energy being needed to keep it on a 60 mph level flight. These are well established facts. Now therewith if this glider while in this amazing 60 mph flight, because of the lift already under it's wings, could then be pulled upwards from above as a 500 lb object (rather than a 1000 lb object) at a mere 2.2 mph, while still only placing 16.666 lbs of pull on the tow line, more energy would be saved in the lifting process than is being used to pull the glider ahead, and thus free energy would be attained. This indeed sounds impossible (and likely is), but it already seems impossible for the glider to be able to so easily carry weight on thin air, and so easily it actually needs less pull to carry and transport weight on thin air then what most wheel transportation machines do on the solid ground! What wheel machine can carry and transport 1000 lbs with only 16.666 lbs of pull? Regarding the glider, the 16.666 lbs of pull provides both the thrust to overcome all the 1000 lb glider's head on air resistance (at 60 mph) as well as providing energy to maintain lift on the wings and keep it from descending in the least. Can the train, which is likely the worlds most efficient wheel machine, do much better than the efficient glider? To do better than an efficient glider, a train weighing one thousand tons should be able to be pulled on a level path with 16 tons of pull or around a 1/2 inch cable. The Bible and not without reason, speaks of the wonder of the eagle in the air.

A careful test in a wind tunnel, should give the answer regarding the issue of lifting a 1000 lb glider floating in a 60 mph air current upwards at 2.2 mph as only a 500 lb object ( as was spoken of above). Note according to a chart at NASA regarding lift on wings under various situations, this 1000 lb glider should be able to be lifted upwards at this rate of speed as only a 500 lb object as it glides at 60 mph. If that is true and this would not increase drag (pull harder on the tow line), free energy would be had, and which indeed seems impossible.

Since it only takes 2.666 hp to make this glider fly on a level path and at 60 mph, and it would appear that at least 1.333 hp of energy would be wasted in the friction of the air about the gliders body and wings, according to energy calculations only 1.333 hp of energy should be left to make this glider easier to lift in this flight, and which would mean that if this glider could be lifted upwards at a mere 1.1 mph as a 500 lb object (because of this flight) without pulling harder on the tow line, free energy would be experienced and energy calculations would not work. Further it is obvious that lifting the glider from above at a some low rate of speed would lesson the pull on the tow string, as the glider would be merely lifted at a rate to eliminate all angle of attack. Although it seems that the glider should pull easier because of only needing to create one half of the lift, if and when a negative angle of attack or an inclined path in the air is encountered more drag likely would be experienced.

Regardless of all the above, in conclusion it would appear that a heavy 1000 lb glider with it's close to 50 ft wing span would demand 16.666 lbs of pull to simply overcome it's head on air resistance at 60 mph without that little bit of pull also providing energy for lift and to keep it perpetually air born. Further it also seems impossible that weight can be carried and transported more easily on thin air, than most wheel machines can transport it on solid ground. Yet it is the wonder of the eagle in the air, and that most overlook and possibly no one fully understands (Pro 30:18-19).

I have many questions about the power of the wind. Wind surfers standing on a water ski apparatus with a sail attached, can travel quite a bit faster than the wind. Further a water ski has quite a bit of resistance and why is it they can travel faster than the wind and seem to be able to go almost in any direction so rapidly. Following is excerpt from a web site.

"How could a sailor go faster than the wind? Windsurfers do it all the time. The true wind speed might be 15 MPH, but windsurfers are screaming along going 20 to 25 MPH. Part of the answer to this (and other) mysteries is blowing in the (apparent) wind: Sailors make their own wind."

This link shows a quite wild windsurfing demonstration.

Amos you have drawn my attention to something vast and powerful.

As a rushing mighty wind, the Spirit of the Lord came on the day of Pentecost!

Jesus said to His disciples that greater works than I have done will you do when this wind comes or when you receive my empowerment! How can the glider [those who are merely riding on this wind] do greater works than the wind itself?

What are we not understanding here? What are we not accomplishing here as Jesus people? What are we not accepting here? Is it the fact that we do not depend totally upon the wind and thus we go about building our own religious engines to compensate in some way?

I am totally interested in this thing of traveling faster than the wind itself and yet by the dependance upon the power of the wind.

You have drawn our attention to something very important here.

thanks.

Dug,
Thanks for your post. It was interesting. May God have mercy on us and send us the help we need.

Regarding wind surfers going faster than the wind, I don't think it is because they make their own wind but rather because their sail is angled with the wind in a manner that when the wind moves 3 ft they may have to go 5 ft to allow the wind to pass. Efficient gliders can actually go 60 times as fast as the wind, as a 1 mph updraft can keep a glider both flying at 60 mph and without any decent.

The reason gliders can use an updraft to fly, but not a horizontal wind is because in a updraft they can use gravity as an anchor or means of force to act against the air movement, while in a horizontal wind a glider simply has to go with the wind and is like a kite that has it's string broken and has no means of acting against the wind. Yet I believe if a glider would have sideways support, such as having a string attached to a little dolly on a tract, the glider could pull the little dolly along while it flies and thus fly in a horizontal wind. I believe in Kansas if someone would put a little dolly on an open railroad track and tie it to a glider they could often fly across the state likely at 60 mph being powered by a mere 5mph horizontal side wind. Yet it could be quite dangerous since you would be flying so low. Further if someone could develop some kind of a water skid that could slice through the water easily and which could provide a glider with side support, a glider should be able to fly across bodies of water at a high rate of speed possibly at 60 mph in a 10 mph wind, pulling it's side support along in the water. The amount of wind needed would depend on how hard the water skid would pull.

Obviously many problems could be had, but the basic principles are very interesting to me. I believe there are many good things out there that are waiting to be discovered. I wish I could discover at least one of them to bless man with.
