Wave Energy Inventions in the Box
Wave Energy is one of the most elusive forms of energy: Only 10 patents or so have progressed to long-term ( >1 year) large scale prototypes for a total of 22 MW.
The competitors choose to stay in the box, but the best ideas always comes out of the Box.
#1 Wave Paddle
- A float or a series of floats are attached to an arm of a main structure.
- A gear box is attached to a turbine at the end of the long arm not unlike a wind turbine: more moving parts in sea water!
- Oyster and Carnegie “HiWave” use a wave-powered pump which pushes high pressure water to drive an onshore hydro-electric turbine.
- The wave-energy farm has three 100 kW WaveRoller units, and each of these has a 8 x 12 meter panel: more moving parts under seawater.
- WERPO operate at the shore, where the waves are not as powerful but the cost of operation is not expensive.
They are planning to build a system for the West African government of Guinea-Bissau.
#3 Oscillating Air Column
- Wave action drives a pair of counter-rotating turbines, each of which drives a 250kW generator
- Specific to only certain areas – some located away from populated areas or transmission lines, but at $0.04/kWh
- The first OWEL 500 kW prototype will be 42 meters long.
Waves cause the sea water with kinetic energy to rise and the resulting force air engages a turbine in both directions.
#4 Pelamis Wave Power
- The mechanical pressure applied at the joints is created by swells for the hydraulic pumps.
- Pelamis Wave Power Ltd. delivered .75 MW/ systems.
- The power/ton was not very high or the power density was low.
- They couldn’t raise the money to continue development.
#5 Point Absorber Buoys
The flotation portion undulates with the waves, while a shaft fixed to the sea floor provides the counter-active force.
#6 Rotating Device
- Inside, a rotating device (red) connected to a current generator (yellow) converts the waves’ kinetic energy into electricity. Named: “The Penguin“ by Wello
- In the second example, waves pass under the SeaRay, they cause magnets to move up and down (ratchet) around the coil. The motion causes a changing magnetic field, generating voltage: an underwater turbine spells eventual frequent compete replacement. Imagine if you had to replace a 100 of these at the same time: the Power Company would not be amused.
- The Floating Spine Device uses the same ratchet principle.
#7 Lop-sided Rotating Device
WET-NZ wave energy converter, now known as Azura, was tested off Oregon in 2012: the float can rotate continuously through 360° or oscillate back and forth for only 20 kW.
#8 Hann-Ocean Technology: Drakoo
- Drakoo works well on small waves, yet the low power/ton (pilot: 4 kW) makes this system too expensive.
- If place in a location of large waves (2.5m – 5.5m high), the cost of transmission is prohibitive.
- Resen Waves has two parallel floats and a cylindrical pivoting arm, between the two floats: 25 kW
- The 40South Energy technology works like a jellyfish that moves with the sea: 13 watts to 60 kW
- A Spindrift Energy device consists of a buoy rigidly connected to a deeply submerged tube. The buoy’s movement in response to passing waves, drives the attached tube up and down. A turbine extracts its power, which is then transferred by shaft to a generator or alternator inside the buoy.
A. Overtopping Device
- To reduce the wobbling, the Wave Dragon above needs to be large and heavy: 237 tons.
- This is the closest innovation to the HUG with the addition of an Artificial Reef in order to create a very high slab wave in front of a reservoir.
B. The OVER TOPPING HUG (Out of the Box):
- The first step is to build a HUG Artificial Reef with large dimension pipes on the ground; it can be sealed so that it can float on the water and be towed.
- An alternative is a man-made reef created by dump trucks from shore on a road worthy seawall.
Types of Power Take-off
- Hydraulic Ram
- Elastomeric Hose Pump
- Air Turbine
- Linear Electrical Generator
- Hydroelectric Turbine
- HUG Helical Turbine
HUG Wave Energy Reservoir
- Wave Power has been estimated at 17 to 39 kW/meter.
- The HUG Artificial Reef can capture 100 m – 200 m of Slab Wave Energy or 11 MW to 28 MW.
- The HUG is capable of capturing 80% of wave energy.
- The HUG Float captures 2 MW of wave energy for $1.3 million.
The HUG sends high pressure water to shoreusing submersible pumps for THREE USES:
- Creating 10.8 MW of electricity
- Powering an Electrolysis System to create Hydrogen.
- Creating a Reverse Osmosis Plant for desalinated water.
- Drinking Water
- Water for Irrigation to 30 km from shore
#1 Low Maintenance HUG
Small HUGs in array: mass produced: low cost
Light HUGs: energized by small waves
The HUG Wave Energy System can be located in populated places that only have moderate wave action by creating a high slab wave.
The HUG can be built at minimum sizes according to the needs and the budget availability.
Imagine: an Island Electricity Revolution!
#3 Extremely Profitable HUG
High Capacity; High Energy Density
The HUG Wave Power System produces high power density of 11 MW earning $26 million/year @ $.34/kWh (Hawaii).
The operating cost is negligible during its entire lifetime of 30 years: $0.02/kWh. A green energy grant of $0.01/kWh can reduce this cost.
Return on an initial $10.75 million Investment is 240%/yr.
Wave Power beats Solar & Wind Energy
Look at the advantage of the HUG Wave Power over both Solar and Wind Power: less cost, higher revenue and higher ROI.
Experts have calculated that wave power from the oceans could provide 70 per cent of the world’s energy requirements.
Using the power of the Slab Wave, the kW/meter increases dramatically.
Wind and Solar Renewable Energy only works some of the time.
HUG Technology is “Base load” Renewable Energy technology that works 24/7.
According to the federal Energy Information Administration, the “levelized cost” of new wind power (including capital and operating costs) is 8.2 cents per kWh. Solar energy is more expensive: 10.5cents per kWh. Compare this to the HUG: $0.01 – .02/kWh

Cost /kW = $995 or $0.14/kWh: 1.8 MW x 6 HUGs = 10.8 MW
10,800 kW x 7884 hours/year = 76,630,000 kWh/year
INCOME: 76,630,000 kWh/year x $0.34/kWh = $26,055,000
Return on Investment (ROI) = 240% in the first year and Year 2 to Year 30: 230% /year.
Year 2- Year 30: O&M annual cost is ($1,390,000) $0.018/kWh less $0.01/kWh (Carbon Tax Grant)
The Pay-back period for the HUG (with a wave height of 13 m and average period of 7.3 sec) is estimated to be less than one year in Hawaii.
A Budget of $1,300,000 supports 1 HUG = 2 MW
A Budget of $35,000,000 supports 18 HUGs x 1.565 MW = 28.2 MW
#4 A Surfing Tourist Attraction The Pay-back Period for a HUG Wave Energy System with significant wave height and average period of 7.3 sec, the pay-back period is estimated to be one year in Hawaii.
- We are at the cusp of a new commercial Tourist Attraction.
- There are only a limited number of perfect surfing waves.
- The surfing site : NO sharp jagged bottoms.
Add a Fish Farm to the 20,000 square meter Reservoir.
For People who have no Electricity
Imagine if some of 1.5 billion people living near the ocean shore, who have no electricity, would now have access to electricity: would they not become part of the First World?
