Flywheel-based products

        Our patented composite flywheels offer superior reliability and performance at competitive costs compared to other energy storage devices. Our composite flywheel is a rotating wheel on hybrid magnetic bearings and operates in a near-frictionless vacuum-sealed environment. The flywheel is powered up to its operational speed using a permanent magnet motor and electricity from an external power source (typically the grid). When the composite rim spins, it stores energy kinetically. The

flywheel is able to spin for extended periods with great efficiency because friction and drag are virtually eliminated by the use of hybrid magnetic bearings and a vacuum-sealed environment. Because it has very low friction, little power is required to maintain the flywheel's operating speed. When electrical power is needed, the momentum of the spinning flywheel drives a generator and its bi-directional inverter converts the kinetic energy into electrical energy.

        Our products employ enabling materials such as high-strength fiber, efficient electric drives, and low-loss, long-life bearings to create new generations of flywheel products. Our composite flywheels are fabricated from a proprietary mixture of high-strength, lightweight fiber composites, such as graphite and fiberglass combined with resins, which allow the flywheel to rotate at high speeds and store large amounts of energy relative to similar size and weight flywheels made from metals.

        Our products employ an internal rather than external vacuum system and its bearing systems have been designed and developed to need low scheduled replacement or maintenance. In contrast, many competing flywheel products rely on bearings and external vacuum systems that require periodic maintenance and replacement. Our Smart Energy flywheel systems have dramatically longer discharge times than any other flywheel energy storage systems known to us; this is possible because our technologies result in higher amounts of stored energy and minimal energy losses during operation.

Our patented composite flywheels offer superior reliability and performance at competitive costs compared to other energy storage devices. Our composite flywheel is a rotating wheel on hybrid magnetic bearings and operates in a near-frictionless vacuum-sealed environment. The flywheel is powered up to its operational speed using a permanent magnet motor and electricity from an external power source (typically the grid). When the composite rim spins, it stores energy kinetically. The flywheel is able to spin for extended periods with great efficiency because friction and drag are virtually eliminated by the use of hybrid magnetic bearings and a vacuum-sealed environment. Because it has very low friction, little power is required to maintain the flywheel’s operating speed. When electrical power is needed, the momentum of the spinning flywheel drives a generator and its bi-directional inverter converts the kinetic energy into electrical energy.

Steel flywheels have been used since the industrial revolution in applications such as piston engines to store energy during the power stroke for release during the compression stroke. These applications are limited by the revolutions per minute at which steel flywheels are able to operate and by the limited density of storage of energy by volume of steel. Our products employ new enabling materials such as high-strength fiber, efficient electric drives, and low-loss, long-life bearings to create new generations of flywheel products. Our composite flywheels are fabricated from a proprietary mixture of high-strength, lightweight fiber composites, such as graphite and fiberglass combined with resins, which allow the flywheel to rotate at high speeds and store large amounts of energy relative to similar size and weight flywheels made from metals. For example, a 600-pound steel flywheel running at 8,000 revolutions per minute (RPM) will store approximately 900 watt-hours of energy and can deliver up to 850 watt-hours of energy. In contrast, our 500-pound 6-kilowatt hour composite flywheel running at 22,500 RPM stores 7,200 watt-hours of energy and delivers 6,000 watt-hours of energy. On a per-pound basis, composite flywheel technology delivers nearly 10 times the energy of steel flywheels.

Our proprietary technology enables the design of maintenance-free flywheel products in that our products employ an internal rather than external vacuum system and its bearing systems have been designed and developed to need no scheduled replacement or maintenance. Many flywheel products rely on bearings and external vacuum systems that require periodic maintenance and replacement. Our Smart Energy flywheel systems have dramatically longer discharge times than any other flywheel energy storage systems; this is possible because our technologies result in higher amounts of stored energy and minimal energy losses during operation.

Our patented composite flywheels offer superior reliability and performance at competitive costs compared to other energy storage devices. Our composite flywheel is a rotating wheel on hybrid, magnetic bearings and operates in a near-frictionless vacuum-sealed environment. The flywheel is powered up to its operational speed using a small motor and electricity from an external power source. When the composite rim spins, it stores energy kinetically. The flywheel is able to spin for extended periods with great efficiency because friction and drag are virtually eliminated by employing hybrid magnetic bearings and a vacuum-sealed environment. Because it has very low friction, little power is required to maintain the flywheel’s operating speed.
