The Velkess Flywheel: A more flexible energy storage technology (Phys ) —A new Kickstarter project called Velkess (Very Large Kinetic Energy Storage System) has recently gotten underway to

Armed with the pioneering research of John Vance, a retired professor at Texas A&M University (TAMU), Gray has developed a novel approach to flywheel design with a patent pending flywheel

Velkess flywheels can be connected in parallel to increase storage capacity, making this design a potential player in the grid-level storage market. In addition, flywheels can be used in electric vehicles. Regenerative braking converts mechanical energy (the car''s motion) into electrical energy.

Flexible flywheel offers cheap energy storage . Mechanical engineering isn''t within the scope of Vulture South, so we''ll welcome readers'' input about whether this is genius or snake-oil: a Kickstarter project called the Velkess Flywheel hopes to offer low-cost energy storage.

Velkess is working on a prototype flywheel storage unit that''s small enough for distributed generation applications. The unit would have about the footprint of a typical home refrigerator, says Gray. The unit would be able to store 15,000 kilowatt-hours of electricity, losing only about 2 percent of its stored power to friction each day.

The company has been building prototypes of flywheel energy storage systems designed, as Velkess CEO Bill Gray tells ReWire, to offer a plug-and-play

The Velkess Flexible Flywheel promises energy storage technology at a "radically lower cost." Think of a house with solar panels on the roof. During the day the house receives enough energy from the Sun to power the lights, heat, air conditioning and appliances in the house. Excess energy drives a flywheel which stores up the energy it

The Velkess flywheel, or VEry Large Kinetic Energy Storage System, is innovative in that it removes the need for electricity to initially boot up the flywheel. Regardless of the initial energy input, beit electricity, magnets, or manual rotation, a flywheel is able to capture quick bursts of energy efficiently by taking energy that would

Velkess''s flywheel is flexible and works very much like a cowboy''s lasso. Our flexible system embraces the natural dynamics of the rotor, redirecting any stray energies into stabilizing counter forces.

Active power Inc. [78] has developed a series of flywheels capable of 2.8 kWh and 675 kW for UPS applications. The flywheel weighs 4976 kg and operates at

Flywheels actually deliver almost all of these, except for cost, which is still an issue. The table below shows projected cost figures given in the 2011 ORNL report with an additional line item for the Velkess flywheel,

Velkess'' 3kW-15kWh Flexible Flywheel module provides robust, efficient, and long lived energy storage creating a new frontier for price and performance in the industry. Velkess makes Solar Price competitive

5 · Velkess Flywheel. (Phys ) —A new Kickstarter project called Velkess (Very Large Kinetic Energy Storage System) has recently gotten underway to bring an

Flywheels may be getting a second life, however. Silicon Valley inventor Bill Gray has a new flywheel design that would deliver distributed and highly scalable storage for around $1,333 a kilowatt

Flywheels lose a lot of energy due to air resistance and friction. The Velkess flywheel operates in a vacuum-sealed chamber with magnetic bearings to reduce wind

Back in 2013 the Velkess flywheel was supposed to be a drop-in replacement for 48V lead acid and cost around $1300/kWh. Their secret sauce to reducing costs was a flexible flywheel that didn''t require precision and so would be cost effective. So it seems like a great technology if someone can figure out how to reduce the

About Us. Velkess'' purpose is to make high quality energy storage economical and ubiquitous. We believe that energy is not just a virtue but also fundamental to modern prosperity. The more energy you have, the better off you are. Our legacy fuel-based generation creates pollution and dependency. That does not need to be our future.

Update 3 januari 2017: Bill Gray, de ontwikkelaar en oprichter van Velkess, heeft de handdoek in de ring gegooid.Dankzij de snelle opmars van betaalbare thuisaccu''s is de businesscase van het Velkess Flywheel nu niet meer zo aantrekkelijk als hij in 2013 leek. "Het liep hard met de bestellingen en er was veel interesse vanuit investeerders", zegt Gray.

Info on the project

His invention is called Velkess- Very Large Kinetic Energy Storage System. This invention uses super elastic materials to re-transmit the non-coherent mechanical forces and unnecessary vibrations by working with the usual rotor dynamics, and reduces the wobble existing in the current design of flywheels.

Future of Kinetic Energy: Storage. Home use of flywheel energy storage is the next hurdle for this technology. For companies like Velkess they want this technology to store all the energy your home produces from wind and solar energy generation. The key moving forward will be reducing costs and improving efficiency.
