The HUG uses the physics of the vortex to create a spiraling motion to accelerate the flow of fluid in order to generate electricity or provide irrigation pumps from the water flow from tidal flows, waves, rivers, rapids, ocean and other fluid flows using a helical turbine and to transfer this fluid like water, oil or natural gas at near zero friction.
There are many applications or spin-offs of the HUG, a new invention or a new good, which are named by their function:
- The Funnel HUG, used in ‘Run-of-River’ (Run-of-River HUG), and in a waterfall (Waterfall HUG) and the Reservoir HUG used to house an array of Funnel HUGs.
- The Pump HUG used in a river (River HUG), at a pylon (Pylon HUG), in an ocean current (Ocean Current HUG) and a tide (Tidal HUG)
- The Wave Energy HUG: creating electricity from wave energy
- The HUG pipe or HUG pipeline
- The Recycle HUG to recycle gray water
- The HUG Siphon for Waterfalls, Watermills and Dams
The “prior art” helical turbine is used to provide rotation to either the submersible pump or the electrical generator. One of the companies—GCK Technologies Inc. has a patented turbine using the helical blade. Lucid Energy Technologies patented the same helical turbine in a pipeline, but there is no vortex claimed for either patents.
The Wave Energy HUG utilizes an artificial reef in order to create a slab wave. The “prior art” artificial surfing reef has a filing date of September 3, 1991. The abstract reads: “The artificial surfing reef is a generally Y-shaped structure made of many large sized polyvinyl chloride pipes…”. As a swell moves toward the shore, its bottom is resisted by the artificial surfing reef to form the perfect surfing waves. The closest competitor is a system called Wave Dragon, which is as heavy as a ship of the same size: the waves are much smaller and the turbines do not use the power of the vortex.
All these prior systems do not use the physics of the vortex in order to increase the velocity of the laminar flow. Hence, many companies have patents for much larger and more expensive turbines, simply because the velocity of the flow has not been accelerated by a vortex. Typically they place their turbine directly into a tidal flow or rapids: the size is so large that maintenance becomes a big factor.
Imagine having a hundred such huge systems in a set of rapids and then having to raise each for maintenance. R.E.R. had such a prototype at the Lachine Rapids near Montreal and they were finally producing electricity at 2.3 kW/m2. The system was so huge that they had to replace the blades of the turbines with stronger alloys and their system required an underwater generator (you never mix electricity with water).
R.E.R. had to declare bankruptcy because they could not find a buy like ABB Inc. (Canada), who was already part of a consortium and who was willing to take on the guarantee of providing constant electricity.
There are ways a business communicates the value of innovation to financiers: industry benchmarks that allow the investor to compare the business to other similar businesses.
How the Technology Innovation is different than the Incumbent Technologies
Presently no patents exist to capture energy from fast moving rivers up to now. The Power Density of any pilot projects designed to capture energy from tides is 2.4 to 6.9 kW/m2. This Power Density is a measurement of the efficiency of a hydro electric system: the area The reason for the low efficiency is that the flow of a current treats all these turbines as obstacles to be avoided.
The HUG Power Density is an unbelievable 73.5 kW/m2. The Power Density increases to the cube of the velocity and the HUG velocity is four times faster than the competition. This is why the HUG can be small and modular.
The most important consideration is the HUG cost: the Cost of Construction for a 100 MW project is $88.5 million, which is 22% of the typical average cost . The HUG cost of $885/kW is unusually low compared to most other hydro electric generation systems. In 2009, Hydro-Quebec (Canada) was permitted to build a number of hydro projects totaling 4500 MW, with a total price of US$ 23 billion, which is $5,100/kW.
The present costs of generation of small hydro plants are in the range for small hydro of $45–120/MWh with an average of $83/MWh. There are still many ideal sites, which are close to the existing electric power converter/generators, thereby reducing these costs by a further 40%.
The cost per mega watt hour of the HUG is very low at the rate of $5.46/MWh, which is 360% on the low side and 1,100% on the high side. The Energy Availability Factor (power plant performance) can be increased by the same range
HUG can provide extra revenue from the upcoming sale of carbon credits: those companies, which exceed the emission limits, will soon be forced to buy $284,000 worth of carbon credits for every 1 MW of new clean energy.
The United States Department of Energy has approved a second round for Hydroelectric Production Incentives allow for up to 2.3 cents per kWh — indexed for inflation, which amounts to $180,000/MW. The maximum payments of up to $750,000 per year for energy generated by facilities (4 MW) during the incentive period.
The risk factor is low because the initial Prototype & Feasibility Study of the HUG costs only $750,000. New technology in the form of three-dimensional printing further reduces the risk of a high cost prototype. This 0.24 MW power project has an admirable cost recovery of $65,350/yr. The Return on Investment is 17.5%/yr.
There are 5500 locations for a total of 11,000 MW in Canada alone where this technology can be applied according to studies done to support low head (1.5 m -3 m) turbines . It was estimated that as much as 3,400 MW of electricity generation potential could be exploited in U.S. rivers by small, unconventional systems such as free-flow (damless) turbines.( Hall et al. 2004)
Remote areas do not have access to expensive dams and so electricity is a northern company’s biggest cost after labor. Northerners use costly diesel. Mines in remote areas would pay premium prices for this technology.
HELPING SOLVE THE WORLD’S CARBON POLLUTION
New Trees are the only solution to soaking up Carbon Dioxide:
Our Mission: to help solve the problem of carbon dioxide build up in the world by growing and managing mature forests of foliage, fruit and nut trees that eventually are used in lumber — not firewood. The Carbon Tax Fund supports a Micro finance initiative to support women farmers and their families who will nurture fruit and nut trees over their lifetime. The Net Present Value of each tree is $0.49/tree plus $1.00/tree for auditing and maintenance for 25 years.
