What is EiP?

EiP Technology

Electronic Inertial Power™ is a breakthrough technology – we have 30 claims approved by the USPTO in our patent filing through Perkins Cole.

How it Works

A simple way to understand it is to consider ocean waves. Say a large winter swell with 15’ faces hits somewhere on the west coast of the United States. That swell started in the Gulf of Alaska, with sustained 40 knot winds over a 6 hour period. The local swell created was a sloppy mess of wave energy. Theoretically, if the same wind would have blown in the opposite direction in the Gulf of Alaska right after the initial storm hit, the waves would have cancelled themselves out.

But something interesting happened over the course of time it took that swell to hit the US west coast. All the little disorganized waves became organized into a large open ocean swell – an oscillation not unlike the EiP oscillation. Now if you blew the same wind against that big swell with 15’ faces that originally occurred up in the Gulf of Alaska, the winds would create lots of surface ripples but hardly impact the size and force of the oscillating swell. With EiP technology, we take all the little energies from wind or other renewable sources entered into our machine, and convert that power into oscillations with an intensity similar to this large groundswell. This is how we produce high power from a slow-moving rotational mass.

Now let’s take this a step further. This swell is going to continue travelling down to South America. And because it’s oscillating at a natural frequency, it will not decrease much in size. Say it decays from 15’ to 12’ by the time it hits South America. Now what if there was a way to pulse small focused amounts of energy at specific intervals into the swell as it travels to South America, in order to maintain the 15’ faces. That is how we create EiP storage. We trickle in just enough energy, switching at 40,000 per second, to maintain the stored power trapped in each EiP machine flywheel oscillation. When 4 EiP machines operate together in a cluster, each machine feeds the others so that all machine oscillations are maintained without the need for external power input. This sounds like a perpetual motion machine but it’s not – it’s the Electronic Inertial Power oscillation providing ultra-efficient use of power. Large scale battery storage becomes unnecessary at this point.

This example illustrates how we are able to generate and store high power from a slow moving rotational mass. EiP machines in combination with solar panels can provide 100% on-demand renewable power, without little or no batteries depending on configuration.

Introducing: The EiP Wind Machine

A bird-safe, stationary cylindrical structure 8′ wide by 6′ tall
that sits on four legs about three feet above the roof.

EiP Technologies has created a machine that generates wind power and storage on urban rooftops. External blades are fixed and concentrate wind of any speed and direction, including gusts and turbulence, toward internal wind blades rotating around a vertical axis.

The center of the machine is hollow, which allows turbulence from wind power conversion to exit top and bottom while intensifying straight-line wind that drives rotor blades on inflow and outflow. The rotor is bird safe and never moves faster than the wind. The rotor is a single moving part that converts wind energy directly to electricity. Developed right in the middle of one of the windiest places in the world, the EiP machine is self-regulating in high winds, which allows continued power production during conditions where all other wind machines would fail. EiP technology combines permanent magnets, generator coils, and electronics in a modular patented way to extract full power from a heavy low speed rotor. EiP wind machines provide power regulation and storage, minimizing or replacing the need for batteries when used in a microgrid with solar panels and other renewables.

Power Generation from the Wind

Our vertical-axis wind turbine (VAWT) design is ideal for high power production on urban roofscapes. Historically VAWT designs have not been able to spin fast enough to draw enough power to be economically viable. We have solved this problem with our super-efficient industrial motoring technology that allows magnetic flux to do the work rather than a driveshaft. Our machines have been tested in wind speeds up to 92 mph with no breaking or furling required. Our wind curve (representing available energy across a range of wind speeds) starts at 2 kW continuous idling power when no wind is present. Any gust will be instantaneously converted into additional power, and sustained winds above 20 mph increase power exponentially. These features are unheard of in wind machine design. We have yet to discover an upper power limit in high winds. Unlike large turbines, EiP wind machines produce power in turbulent and gusty winds that are common in cities. EiP machines are very reliable with only one moving part. No tower is required when placed on rooftops. Our two models are rated at 50 and 100 KW. Since EiP machines local loads, all power is consumed with no transmission loss. Each machine weighs about 2000 lbs., which most commercial rooftops will support.


In addition to producing power from the wind, EiP wind machines also regulate and store power extremely efficiently. We have added a large mass to the one internal rotating part, to create an electronic-mechanical flywheel storage device. Our patented electronics use a small trickle of power to build up a large amount of kinetic energy in the flywheel, which provides an added source of energy to create the EiP oscillation, which maintains rotor speed regardless of wind and load. This is the heart of ‘Electronic Inertial Power’ technology. Machines can be powered up from the wind, solar panels, or a trickle from the grid to reach EiP oscillation. Once oscillating, machines will maintain the flywheel rotation indefinitely, powered by all of the energies present in the system, from wind, inertia, and load changes. Any power added to the system, say from wind or solar, serves to increase total storage capacity. EiP machines used in clusters will replace the need for battery arrays currently being considered to back up solar and other renewables, with no toxic waste, fire hazard, or maintenance requirements. Radically different from batteries, our storage capacity increases instantaneously as the wind gusts or any other power load hits. The fact that storage capability comes ‘included’ in each machine solves the local storage problem and creates a great partnership between EiP wind machines and solar panel technologies.

Microgrid Design

EiP wind machines can be networked together in microgrids for increased performance. In a network of 4 or more machines, placed on urban roofscapes, power and storage can be shared between different buildings. Solar panels can be built into the design to optimize power regulation, generation, and storage for the given local wind/solar characteristics. All excess energy produced during peak times can be stored to drive local loads at a later time. Since EiP machines can be configured for energy production or storage, and provide power during disastrous weather conditions, a true microgrid is created where all base loads can be serviced without reliance on outside power. Using EiP technology, customers can truly operate under a ‘21st Century Grid’ model, un-reliant on sidecar power plants provided by large power companies. Individual microgrids can connect with the larger grid as needed only for servicing peak loads. Note that local power companies benefits, gaining a more predictable service model and ultimately avoiding costly sidecar power plants to back up today’s large renewable windfarm and solar projects. EiP machines provide a path that truly moves us toward reducing our planet’s carbon power footprint.

EiP Wind Machine benefits

High Power Output

EiP machines are rated at 50 kW. But the story gets much better than a simple rating. Even when idling, EiP machines produce 2 kW continuous power 24×7. Wind gusts are absorbed instantaneously and converted to high power. EiP machines can also absorb energy from elevator breaking, and reduce air conditioning expense by cooling the rooftop. Gusty and turbulent winds are common on urban rooftops; EiP machines absorb and provide power from all these energies.

High Storage Capacity and Resiliency

EiP machines configured for storage absorb power from wind gusts, solar panels, or other renewables and provide continuous and regulated power On-demand 24×7. EiP machines have higher capacity, a much smaller footprint, no toxicity, and are much less expensive than Lithium Ion batteries. Four or more EiP machines will work together to store power indefinitely, with no external backup power required.

Safe and Reliable Operation

EiP machines are simple to install – no tower is required. Rotor rotation is slow, creating virtually no noticeable vibration. There are no exposed external blades – safe for birds and humans! EiP machines are very stable – wider than they are tall with enough weight to maintain operation during hurricane force winds. There is only ONE moving part, the central rotor, supported by physical and magnetic bearings.

Place Wind Machines AND Solar Panels on the Same Urban Rooftop

Imagine turning your rooftop into a power plant! When it’s sunny you get power from the solar panels; when it’s windy you get power from the EiP machine. ALL power is stored in the EiP machines for 24×7 operation, with minimal or no backup system required, depending on configuration.

Low Cost and Efficient Microgrids

EiP machines can be linked together with solar panels in a network. Power generation and storage are all integrated within the system. A small 2-hp UPS would be adequate as a backup system. EiP microgrids can be configured to power loads from 200 KW to over 1 MW – completely adequate for high density residential and commercial applications. EiP microgrids can be interconnected over standard power lines to connect any number of microgrid islands. No batteries required!

No furling

Every other wind machine design requires some type of furling in high winds to restrict blades from breaking up and causing a catastrophic failure. EiP wind machine aerodynamics are self-regulating and naturally performs BETTER in high winds. We have tested and produced power from EiP machines in excess of 90 mph winds.
