Standard-Helical Hybrid Wind Turbine


Most small to extremely large wind turbines installed in the world, are designed in the same way similar to a plane propeller, with three blades as most common number. They reorient facing the strongest wind by the help of sensors and then rotate by the force of the wind, connect the rotation energy through a shaft to an alternator which generates electric energy and feeds it to a collecting battery or directly to the electric grid.

Other designs have emerged during the last few decades, one of them seemed to catch more attention and it was called the Vertical Turbine or Helical Turbine. This design collects wind energy from all directions and can also be more efficient at lower wind speeds. The problem with that design is that, relative to its area, it does not collect as much energy as the standard propeller design, so its return on investment is low.



What I am presenting here is a Standard-Helical Hybrid turbine, which uses some of the advantages of Helical with the advantages of standard design. Three Helical blades are connected on a central hub and rotate around the hub like standard blades, but also rotate around their center like Helical blades. The rotating hub, increases the relative wind speed and thus increases the efficiency of the Helical blades. The central hub can be connected to the blades by mechanical gears, or could be independent and controlled by a motor driver.

A further investigation of the concept is needed of course. This mechanism needs to be simulated and the geometry of the blades and Hub can of course be optimized for improved aerodynamics and energy collections. What you see in the video below is a concept drawing without accurate proportions.

Quantum Computing using Human Processors



It does not always occur to a person walking on the street, that every individual passing by carries a powerful processor,the brain, mostly using it to navigate in the surrounding space while browsing on the mobile phone (In the field of quantum that phone is in a state of  "Iphone 6S" or "Samsung Galax S6" other states are less probable). As I sat in the library today, again I noticed many people around me sitting and using their brains to the least requirement in a place where people are supposed to be learning, thinking, creating.

If you show a person a banana and ask for its color, the chances are that the answer would be "Yellow" but also with less chance is to obtain an answer of a different color starting by "Green" and then less banana common colors and finally the answers of least chance are of non color answers like "Round". After receiving a hundred answers from a hundred person you could be more assured that the right answer is "Yellow" by statistical analysis.

Now imagine you have a more complex mathematical problem , design problem , or even Estethic Form (lets say a haute couture dress or a car design). If we could develop an algorithm which can disect any of those problems into a thousand smaller problem and send each to a large number of Mobile App user. Each user will use his brain (processor) to solve the small simple problem with whatever hint of subjectivity there is. The mobile app would collect all answers to all fragments of the problem and then through statistical approach of quantum generate the answer of the major problem, we would be creating a quantum computer based on human brain.

In concept:
Suppose the problem P = A + B + C + D where A = 1 + 2 , B = 4 - 2 and so on.
A group of users will recieve problem A and then provide their answers, the collecting server would determin the answer 3 to be the right answer (as it is the most occuring).
Now imagine P to be a car design , A is the front light shape, B is the Rims shape, C is the side mirror.
P = A+ B + C ...
The users can be presented with several options for A, B and C... and the most occurring selections would be gathered into the shape P. 

Another potential of such computing concept is to include the human subjectivity, human perception factor into the equation and then that would result with a more human oriented solution.

Time is Changing as Space Changes

Of what we constantly try to achieve in the physics of science, is continuity and defined systems. By now, most physicist know that in the world of quantum, the approach is by the study of the many and cannot be by the study of a single particle / case.
The first and simple example of the quantum physics is how nuclear decay is calculated for every decaying material. The half-life is estimated for a very large sum of atoms, but the half-life of an individual atom can never be calculated. 

The equation of decay is based on the following form :
λ is the decay constant which is different for every radioactive material. The expected decay −dN/N (decaying atoms per atoms present) is proportional to an increment of time, dt.
So far, what is explained above is nothing new to the scientific approach, but it is worth mentioning that time which is considered a constant measurable value, is in fact a varying value. In Einstein’s theory of relativity, time has a changing value if the measuring device is in motion, time is also varying in the presence gravitational fields.
The method with which we measure the age of things for geology and archaeology is based on nuclear decay. If we assume "t" has always been of exact value, then every dating is considered accurate. 
If we considered that "t" has varied, maybe increased, then all what we know about the time scales of change and the universe, could be wrong.
There are theories that the universe is expanding faster and faster, which would mean that the time constant is changing. At least the Universe has definitely expanded since the Big Bang till today. Again if the universe is expanding then all gravitational fields in the universe are weakening as the large masses are moving away from each other in a general definition and then time is shortening.  Based on that knowledge we could theories that time is not a constant across time and thus we must rethink how we view time.
It is possible, in an exaggerated manner that at a point in the past the 1 second we measure today used to be 0.5 seconds and thus in today’s constant the nuclear decay is two times faster. Anything we date today as 10,000 year old, could be on today’s scale of time 5000 year old.
As we start to think about time as a varying value, and as we know that relative speed and gravitational fields, have effects on that, we could also conclude that time is varying in flow across the distances of space. Now, we do observe stars from far distances and Nebulae, we analyze their chemical composition by several methods, one of them is the light spectrum and the Doppler shift we use to measure their relative speed. Now if we are measuring speed based on a constant time, or based on a light frequency which itself is based on time; what if time varies across space. Then all measurements are faulty and it would be really hard to correct as time would then need to be measured in all areas that light travels in to reach us.
There are few assumptions we could also generate:
1)The age of earth could be wrong and same for the sun.
2)The universe could be expanding at places, and contracting at others. There is a chance that the entire universe is in an oscillation phase which could lead back to the one dot universe and repeat the big bang or could oscillate in around median size infinitely.
3)There is no evidence that the world few thousands year ago, used to be like we observe it today. We could be passing through a phase of relative stagnation at the top of the sinusoidal oscillation curve or maybe at the bottom. The scale of space evolution relative to time is far larger than the scale of days or years we could measure. If the nature of the universe changes every 1 billion years and we are in the middle of that phase, there is no way we could measure it. The counterargument would be , but we can observe stars and nebulas dating billions of years. My answer billions of years on the scale of time we use on earth today. This scale of time again might change across the universe between us and that star.
4)Materials that we thought stars or nebula gas are made of, could be different from the light spectrum we received.Assuming photon oscillation frequencies could be changing across space where time is different.

One final thought : As time slows down at speeds close to the speed of light, then would it stop at the speed of light ? The Energy of a photon cannot be dissipated if it is trapped in time. Only an interaction with other particles can release the energy of a photon.
