Bourne’s RiverStar (U.S. Pat. No. 7,492,054 B2 and U.S. Pat. No. 8,102,071 and numerous international patents)
Kinetic Energy System is a self-contained energy module composed of a stabilizer, energy absorber,
energy transmission and mooring system and energy conversion and control system.
It is designed to be sited in-river in interconnected arrays. RiverStar does not require
a dam and reservoir; instead it harvests hydropower along a section of a river.


Each RiverStar is connected at a depth of ten feet to the next RiverStar module
by a high strength steel cable. Both ends of the cable are anchored into the
shoreline at the same depth. The mooring cable includes the power
transmission and control lines. RiverStar’s turbine is stabilized by
the combination of the cable, the strut connected to a streamlined float
and a rudder that maintains a precise attitude to the river current.
The turbine drives a proprietary generator module.

Each RiverStar’s generating capacity of up to 50 kilowatts in a
4 knot current (varies with current speed).


The RiverStar arrays can be stacked one after the other down
a section of river. An average array is composed of 20 RiverStar-50
units producing approximately 1 MW, enough to power 1,000
average American homes. A version of RiverStar can operate
entirely underwater.

The Bourne power systems are as simple in design as the
3 foot portable RS/TS-SPP Back Pack Power Plant or as complex as
the RS/TS-50, 100 and 300 which are true “energy robots”.
These units are smart self-contained, self powered, multifunctional,
highly mobile, self adjusting, sensor laden and autonomous
energy generating systems.


The system can be applied to each river's environment, culture
and commercial activities as seamlessly and invisibly as possible,
thus opening up vast untapped areas of hydropower worldwide.
In industrialized, populated river sites RiverStar can blend in as small islands,
sand bars and rocky embankments. In rural sites vast numbers of arrays
of RiverStar modules can be seeded across rivers. Farmers across the
country who are already growing corn for ethanol and soybeans for biodiesel
and leasing their land to wind farms may soon harvest the power of rivers
that border their property.

BackPack Power Plant

The Militarized Backpack Power Plant (BPP-ML) measures only 3 feet
in length and is even more rugged, portable and adaptable to extreme power site
demands than the original BPP. Like its civilian predecessor it is self-contained
with its own integrated power, control, cooling and sensor systems. The unit collapses
into three major parts which slide into a large backpack. The BPP-ML produces up to 20%
more power (600W) and can be set up singularly or in arrays of over 20 kW. The BPP-ML,
which operates silently with no heat or exhaust emissions, is 40% less visible during operation
and can also be bottom mounted to be totally invisible.

The BackPack Power Plant (BPP) is a man-portable renewable energy generator only 3 feet in length
and weighing 30 pounds. Each unit is self-contained with its own integrated power, control,
cooling and sensor systems. The unit collapses into a backpack size module with the generator,
hub and folded blades stored inside. The unit produces approximately 500 W/unit high quality continuous power
depending on river current. The BackPack Power Plant can be set up singularly or in arrays of over 30 kW.

TidalStar latest

Each TidalStar (U.S. Pat. No. 7,492,054 B2 and U.S. Pat. No. 8,102,071 and numerous international patents)
Tidal power system uses a proprietary turbine design to produce approximately 50 kW at peak capacity.
TidalStar has many advantages over current tidal power systems. It does not require
tidal barrages, embankments, caissons or sluices. Environmentally neutral,
TidalStar does not increase sediment, accumulate pollution nor affect the
salinity of the water.

TidalStar array

TidalStar utilizes an interconnected arrays of energy absorbing modules
placed across a tidal flow.


OceanStar latest

The OceanStar (U.S. Pat. No. 7,525,212 and numerous international patents) wave power system represents
a new approach to the complex problem of extracting energy from the world's oceans.
Current ocean power systems are dominated by the use of floating devices that
capture wave motion and convert it into electric energy through complex
mechanical and hydraulic means. OceanStar captures the underlying pressure wave,
amplified ocean wave to accelerate and collapse through a series of small turbine
generators. This is an elegant and rugged solution to harnessing the power of waves
which is energy and cost efficient. The OceanStar relies upon a proprietary,
energy efficient process to smooth out the pulse characteristics common to
wave energy in order to be electrical grid friendly. The OceanStar’s high level
of scalability is essential to reach the large surface areas required to reach
utility scale ocean power generation.

OceanStar array

Several miles of OceanStar arrays can be moored offshore to provide a
significant source of clean power while reducing the force of storm surges
upon fragile shoreline areas that are becoming increasingly stressed and unstable.


CurrentStar latest

Bourne's CurrentStar (U.S. Pat. No. 7,492,054 B2 and U.S. Pat. No. 8,102,071) is a self-contained
energy module 300 feet in length. The CurrentStar series is designed to harness
the enormous potential source of clean energy in ocean currents. Ocean currents flow
at all depths in the ocean but the strongest usually occur in the upper layer.
Currents of over 3.5 mph are confined to very restricted regions. There are 14 currents
in the world that exceed 3 knots (3.45 mph), a few of which are in the open ocean.
They include sites in Japan, Australia, South Africa, europe and the U.S.
With its 30 foot beam, the CurrentStar can also serve as a self-sustainable coast
guard station, lighthouse, environmental research center, ship dock/service area for
pleasure and fishing vessels, security/surveillance, safety area and even a tourist hotel.



Bourne's RecoveryStar (U.S. Pat. No. 7,492,054 B2 and U.S. Pat. No. 8,102,071) is a
self-contained energy recovery unit of various sizes and lengths. The RecoveryStar series
is designed to be placed in the outfall river areas of water intensive industrial and power plants
to capture and regenerate waste energy. The RecoveryStar also slows outflow speed, aerates
water, cools water temperature and monitors water quality. The unit can be used to regenerate
energy lost in the electric power sector. 143 billion gallons of freshwater are withdrawn a day
to cool the nation's nuclear, coal and natural gas power plants. That is an enormous amount of
moving water which holds significant amounts of potential hydrokinetic power. The RecoveryStar
can operate in the outflows from water treatment plants and water intensive industries including:

PlugnPlay-quick change specialized functions/upgrades.

Every Bourne power system offers a modern, competitive energy solution
that incorporates the continual development of Bourne’s advanced technologies
including hydrodynamics, advanced materials, power and generator technologies.
