The Future of Solid State Wind Energy – No More Blades

12 min video

I confess to not actually watching that, but I did read a few comments, including:

According to the Powerpod’s website, the company “lacks the ability to produce a quality, custom blade to place in the powerpod.” So, predictably, they’re asking for kickstarter money — for engineers, more development, etc. In other words, the product doesn’t actually exist. As with nearly every other green energy “breakthrough” out there right now, it’s basically someone’s pet science-fiction idea cosplaying as an “invention,” and the patent owners are hoping that all of us will invent it for them by paying other engineers to figure it out. Don’t expect it to be “available by the end of 2021,” as the video above suggests.

Watch the video, then comment. It’s the scientific way.

so is it looking available in 34 days

Watch the video to understand the contents. There is a lot more to it including other methods.

fine we might browse their transcript later on

First up is a Bladeless Wind Electricity Generator called EWICON which stands for

Electrostatic Wind Energy Convertor and uses charged water particles.

Second one discussed is also a prototype called SWET Solid State Wind Energy Transformer and uses a process called electro hydrodynamics.

We’ll call that one ’The Bird Dicer’.

The third one is a larger version of the EWICON called The Dutch Wind Wheel

4th one is from a company called Vortex Bladeless called a Vortex Vibration Resonate Wind Generator based on vortex shredding

5th one is from a company called Savonius Turbines and uses drag

6th is from a company called Halcium called a PowerPod

They were very popular with us greenies in the mid-70’s (which is getting close to 50 years ago).

I’d do it all again and still hold my head high.

All these devices have different efficiencies depending on the environment, which can change with each device has the weather is a highly variable entity.

I would suggest that none of them are as efficient as a conventional horizontal axis wind turbine of the common variety we see all over the place. They may have a few niche applications here and there. But if they were any good there’d already be tens of thousands of them in service, they aren’t exactly new.

In the video they are referring to them as prototypes, yet the one that uses drag has been around for years, maybe those are being shown for inspiration to a new generation to create more robust efficient devices ?

Solar works during the day but not at night

Wind can be day and night 24 by 7 but is very variable

I dont have an average for wind for the whole week, but it would be around.

When they are more efficient, I can see them working along with solar.

That little one might help with a caravan.

That sort of thing.

It would need to be secured to something.

Windy conditions might send it on its way somewhere.

This is quite patently obvious.

Could you plug the wind generators output to the solar input on a solar charger controller ?

or would you need an updated solar wind charger controller?

Thanks Tau.Neutrino for those images. That makes things much clearer.

The electrostatic wind energy generator reminds me of Grant’s antigravity machine on Mythbusters. Needs a very high voltage.

The Savonius rotor is a very old one, there are problems when compared with the three-bladed design.

The vortex shedding from a cylinder is reminiscent of a type of wave energy generator where power is generated by internal flexing.

The power-pod design is also reminiscent of a type of wave energy generator.

But I like the three-bladed design that is most popular. There are good reasons for choosing three blades and good reasons for making the blades as long as possible. Making the blades as long as possible maximises the torque output and hence the power output. For both the Savonius rotor and the vortex shedding design the lever arm is very short which results in low torque.

The three-bladed design gives us better torque than any of the the above alternatives.

I know a person who had a Savonius rotor installed at White Cliffs. After about three years of constant maintenance to keep it going, she gave up on it and left it sit idle. Makes a good roost for the early morning raptors.

Had any of you actually watched the video, your know it all person of 50 years ago would be shown to be just the fuddled memory of of someone who thinks he has an intellectual standing to be preserved. Still this is the way this forum works, forget about the facts (assuming they were ever investigated) and go with the opinion of someone who obviously does not know, yet holds some imaginary position of authority.

I’ll watch the video, no worries.
I’ve also got my own ideas to investigate. It is however all about what your needs are and what your conditions are like..

No it’s not, it is about half a dozen advanced ideas, which should be given fair consideration, rather than being dumped, purely on the ill-considered opinion of someone whose nose was apparently put out of joint.

I have actually computed the wind and water flow around a range of rotors, as part of my job for CSIRO, to determine the rotor that was most efficient. But that was for rotors in mining operations. For wind turbines, I rely mostly on those designing wind turbines and reporting their successes and failures in the regular international conferences on wind engineering.
