Wind Turbines based on Jet Engines 3-4 Times More Efficient & Coming to Market? [VIDEO]
FloDesign, an R&D start-up in the US that has created a wind turbine design based on jet engine technology, just secured $34.5 million to help begin commercial development of its turbines. Lars Andersen, former president of Vestas China, has also just been appointed as the company’s CEO.
FloDesign claims that its turbines are 3-4 times more efficient than traditional open-fan turbines. They have several other beneficial features as well that help economically, environmentally, and in other ways.
.
Reportedly, FloDesign is “aiming to transform itself from a research and development organisation into a mainstream renewables firm.”
The company claims that its technology, “which forces air through a small hole to create a pressure differential,” has garnered the support of prominent venture investors because of its true potential and efficiency, according to Tom Young of BusinessGreen.
Major venture capital investor Kleiner Perkins Caufield and Byers led this funding round, and “was joined by a syndicate of three new high-profile investors: a Goldman Sachs managed investment fund, Technology Partners and VantagePoint Venture Partners.” Additionally, the US Department of Energy (DOE) recently awarded FloDesign an $8.3 million grant.
The FloDesign wind turbines require much smaller blades and are much easier to manufacture and ship (see video above). Additionally, they can be placed much closer together than traditional wind turbines and they align themselves with the wind like a kite on a string. These are a few of the technology’s unique benefits.
Wind power has been the fastest growing source of energy (renewable or otherwise) recently, but if this technology is as good as FloDesign says, perhaps we will see a much bigger boom in the years to come.

I like the concept of this FloDesign but it can’t be true to say its 3-4x more eff.
I suspect the 3-4x increase is really saying its has a virtual swept area 3-4 larger than its physical swept area.
The virtual swept area is what makes it interesting.
The kinetic energy in wind given by 0.5pav³ applies to all wind turbine designs and the Betz limit says the max extractable energy is 59%.
Conventional VAWTs already claim to be about 35-40% eff IIRC.
The claim that pitching can be increased seems dubious as turbines mustn’t shadow each other.
The video briefly shows FloDesigns being packed in a squashed rectangular grid but that would require the wind to be extremely directional perhaps thru a long valley. But then any turbine design could take that advantage. Plus FloDesign creates a more turbulent wake which would mean down wind turbines need further pitching.
The only pitching improvement that I can think of for any turbine type is to use hexagonal rather than square a grid to slightly increase turbines per farm area. In a honeycomb hex grid, each neighbor is equi-distant versus a square grid with 50/50 pitching / diagonal pitching.

Am I the only one who thinks the engine in the picture keep moving?

EXCELLENT IDEA!
GOOD THING THAT SOMEBODY USES ITS BRAIN INSTEAD OF STEEL, PLASTICS, AND ITHER ENERGY GUZZLERS.
AS MI EARLY MENTOR SAID: “WHY MAKE THINGS EASY IF WE CAN MAKE THEM DOFFICULT?”
WE MUST LEARN FROM EXPERIENCE, JUST REMEMBER THE HYDRAULIC GENERATORS WITH WATER TURBINES THAT WERE RECENTLY INSTALLED IN THE EAST RIVER IN NYC AND FAILED.
THE DESIGNERS DISREGARDED THE EXPERIENCE OF THE SHIPBUILDERS AND TRIED TO RE-INVENT THE WHEEL!
CONGRATULATIONS

Will be good if the claims hold.
The Betz law is surpassed in a Dutch windmill-design called Powerball [see Aeroliftpatent windmill. Sellingpoint Home Energy Schoondijke (?) ] by using a construction in which the blades make use of the Venturi principle.
The efficiency reached is 85 %. Starts rotating at a very low windspeed. With the same principle a 10 MW Satelite Windmill can be constructed with
an efficiency of 85% or more.
(I do not understand why they are not operational yet)
Whether the Flodesign in the end is better, I do not know.
