The Wave Energy HUG will be a boon to islands that must rely on importing expensive oil for their electrical generation systems. Most islands do without any large electricity.
Wave Energy is in its early stages of development and there are lots of disadvantages: these new wave energy inventions often have a short life span because of the destructive strength of the waves and even because of the salt water itself. This leads to frequent breakdowns, loss of service, loss of income and an increase of operational costs.
Wave Energy is only a niche renewable energy technology. While other forms of alternative energy like solar, wind and biomass see hundreds of billions of dollars in investment each year, wave energy does not see even $1 billion in investment.
The rate of improvement of the technology has been low, so the experiences which can be shared are less than those of other renewable energy sources. The rate of improvement is much lower than other renewable energy source, simply because other systems are improving on proven ground.
Quite often competitive wave energy plants are built in areas which are remote and far from the grid and at the same distance away from the need for electricity. This makes the connectivity to the grid expensive and difficult — unlike the HUG Technology, which can create an artificial reef in most places, especially in most islands.
Wave energy is potentially more easily assimilated into the grid (compared to wind and solar) because it may be more accurately predictable two to three days ahead and sold as firm power.
Cost is the number one disadvantage of Wave Energy.
The possibilities of the proper technology are so varied: many innovators grope for any solution to this very high potential, so research can be directed aimlessly in many directions. These many approaches lead to speculation on innovation and the costs are high only because of the wrong initial path. This is the reason why some companies have gone out of business as their technology failed in actual field tests.
Many inventions are unsatisfactory because they are heavy and huge and would require expensive regular maintenance. Many of these inventions have a lot of moving parts that can wear out in a harsh environment, especially in the agitated salt-water, which can do a lot of corrosive damage.

The best idea always comes out of the box. The competitors choose to stay in the box: some competitors transfer energy to a large axle, which is connected by a gear box in the same manner as a wind turbine. Others rely on the air pressure created by the movement of the wave to drive a turbine, but at a very low efficiency. Some pushes high pressure water to drive an onshore hydro-electric turbine over long distances on shore. Some use a lop-sided rotating device connected to a current generator. Some use a flotation portion bopping up and down with the waves, against a shaft, which is fixed to the sea floor to energize a linear generator. All these have one thing in common: low power density.
The closest innovation to the HUG is the Wave Dragon technology that uses the over-topping technique. The difference is that the HUG system creates a slab wave, which produces over 3 MW of power through a 10 foot drop to the turbine, while the seven turbines of the Wave Dragon drops to a shorter distance in a straight pipe thereby producing lower energy. The HUG creates a laminar flow which increases the velocity as the flow drops 10 feet.
Let us not forget the additional advantage of the HUG: the long slab wave is an ideal surfing wave for surfers created for any tourist destination.
In the absence of information on how projects operate in real-world conditions and how they affect the environment in which they operate, ocean energy developers cannot attract capital because of the low power density.
Now let’s explain the real reason for the HUG: POWER
The formula for Kinetic Energy is KE= ½ x A x V³ x (.35) efficiency (A = area swept; Velocity) The area of the throat of the HUG is 3.26 m²
Kinetic Energy = ½ x 3.26 m² x (7.7 m/s*)³ x .35 = 260kW/turbine
Acceleration = a = g (acceleration of gravity)= 9.8 m/sec
(Final Velocity)²= 2 x a x s (2 x 9.8 m/sec x 3.05 m)= 7.7 m/sec
During a tidal flood, the distance of the drop of water in the turbine is reduced to 2.6m from 3.05m. (Final Velocity)² = 2 x a x s (2 x 9.8 m/sec x 2.6 m)= 7.14 m/sec during the flood of a tide.
The most critical factor is the velocity of the flow. It is the same energy of a 10 foot waterfall: the laminar flow increases the velocity of the flow inside the HUG, which accelerates at 9.8 m/sec and travels at a velocity of 7.7 m/sec.
Now let us look at the other huge advantage. There are only a limited number of beaches have the desirable near shore ocean floor bottoms that provide perfect surfing waves. You now can select the best location for an artificial reef — in a popular tourist area with prevailing winds because the artificial reef can create high waves. Your site selection doesn’t include sharp jagged urchin filled bottoms. What you have created is a surfer’s paradise. Surfers can ride the wave all along the artificial reef, which is properly angled for maximum action. What a tourist attraction! We are on the cusp of commercial viability.
The construction of many artificial reefs involves very heavy equipment such as barges with the cranes, and is very costly. The HUG Artificial Reef is built with light and environmentally inert material and can be easily transported and in-stalled at locations very close to the shore. It is build over an internal core made of rubble stones and an armor of one upper layer of special blocks leading up to the raised artificial reef.
After the whole reef structure is built on the ground, it can be sealed so that it can float on the water and be towed to the surfing location for installation. In addition, an installed reef structure can be removed by pumping air into its inner hollow chambers so that it can re-float on the water and be towed away to a different location or be inspected or serviced. By opening the valves the three inner integral chambers of the artificial surfing reef will be filled of water, and the artificial surfing reef will submerge onto the offshore ocean floor bottom. This is preferably done before the reef 8 is towed out to sea. It is desirable to have towing ring or hook members.
The assembled PVC pipes may be further filled with concrete to ballast the whole reef structure, so that the generally Y-shaped artificial surfing reef is heavy enough to not move with large ocean swell when it is submerged in the water, but not too heavy to prevent it from being re-floated.
A leading leg can be added to the generally V-shaped triangular reef to extend forwardly from the joint of the reef toward the deep ocean direction to thereby form a generally Y-shaped artificial surfing reef.
The two main legs of the generally Y-shaped artificial surfing reef are attached by a large hinge to each other and to the leading leg at their proximal ends, such that when being towed on the water, the two main legs can swing-in to be parallel to each other and aligned with the leading leg to reduce the hydrodynamic resistance; and when being installed, the two main legs can swing-out by a certain angle to form the two diagonal legs of the Y-shape.
The large number of PVC pipes may be bonded together by any suitable mechanical methods using suitable hardware made of environmentally inert materials, such as PVC plastic, stainless steel, fibreglass, etc., or by other suitable methods such as gluing or heated welding. The end caps and couplers will add thickness to the outside diameters of the PVC pipes, which prevents the prefect bonding of the PVC pipes and nesting of the stacked layers. To solve this problem, a modified triangular shaped extrusion member is fitted in the central space between the three adjacent PVC pipes.
The HUG is the right path because it has the ability to capture over 80% of the wave energy at a low cost:
• The HUG Wave Energy System has very low cost of construction: an artificial reef, a reservoir and the light-weight HUG System
• The artificial reef used by the HUG, if properly built can withstand strong ocean waves, storms or typhoons because they are built below sea level. The HUG themselves are protected within a suggested 10 foot high reservoir.
• The maintenance of the HUG is easy: a crane lifts and replaces each of the six HUG systems.
• The over-topping technique which creates a high slab wave created by an artificial reef allows for more flexibility: the HUG can be located in more places that only have moderate wave action.
• Even in areas of insufficient wave strength, an artificial reef can change the potential in any given area, which requires electricity, especially on islands. The prevailing wind is the only variable. In contrast, the competition depends on waves which can be intermittent in nature.
• The HUG System can be built at various sizes according to the needs and the budget availability. This is not possible for other energy forms which require a minimum large size such as coal, nuclear, etc.
• The HUG does not disrupt marine life. Any fish caught in the turbine will experience a twist but they will not be chopped up.
• The thick high volume of the slab wave entering into the reservoir all along the length of the artificial reef will allow for many more 6 unit HUG Power Systems inside the reservoir each producing 1.5 MW. The only variables will be the length of the artificial reef and the size of the reservoir.
• Hydrogen production for hydrogen operated automobiles becomes a reality if the cost of electrolysis is less than $0.05/kWh. Once full production is realized, the actual cost of a 6-unit HUG Power Systems will be reduced by 50%.
- A Wave Power Plant can cost around $6-10 million to be spent in building one Megawatt. The average HUG Power Plant produces three times the power for the same investment because of its high power density. The operating cost is negligible during its entire lifetime of 30 years: $0.02/kWh. An offsetting green energy grant of $0.01/kWh may reduce this operating cost.
The HUG Wave Energy System produces three times the power for the same investment because of its high power density of 3 MW: earning a NET $1.5 million/year.
The operating cost is negligible during its entire lifetime of 30 years: $0.02/kWh. An offsetting green energy grant of $0.01/kWh can reduce this cost.
The Return on Investment is 19.4% in first year.
