Run of river, tidal, and wave turbines for cities near water
Medium Sizsed Wind Turbines in city suburb
Later integration into a energy management system integrate into solar, ground and all other clean energies to form an optimized energy system for smart city
Integration of all kinds of clean energies to make energy supply intelligent:
Optimization of the intelligent supply of diversified clean energies can reduce user's energy costs
One of the important uses of renewable energy is to relieve "peak power" - usually the hottest afternoon in August when everyone turns on air conditioning and there is a risk of a blackout.
In cosastal areas, wind and solar work together to provide power throughout the day, but wind is better for late afternoon.
Example of integration wind and solar
Potential Market in China
Make urban wind as widespread as solar, Over 1 Trillion RMB in China Market. Generate 5% of grid power in most major markets in 20 years.
Technical bottleneck is the main obstacle of wind application in cities, flower turbine provides the best solution
Unsolved problems of small wind are a barrier to urban applications
Flower Turbine is the first wind power solution for dense Urban environments
First small wind turbine connected to the Israeli grid
Prize for Second Best Israeli clean technology, Cleantech Open
In 2018, China s energy administration issued a policy to encourage development of decentralized wind integrated with other clean energies: solar, biomass, geothermal and ocean , effectively connect with smart cities for energy supply
Problems with traditional small wind turbines
Too big, but even when small…
Noise and vibration
Density causes turbulence
Minimum starting speed 3meters/ second (6.7 miles/ hour)
Flower Turbines : The First Wind Power Solution for Dense Urban Environments
Small ~3-meter (118 ) diameter footprint
Quiet, less than the wind itself
Density improves turbine performance (+20% to 50%)
1.2 meters/ second (2.7 miles/ hour) starting wind speed
Turbulence Major Enemy of Efficiency
Leviathan solves the 3 sources of turbulence. And have a patent addressing each.
Cluster Effect
Other turbulence reduces efficiency - 50%
Leviathan Cluster Effect increases efficiency
+20-50%
Energy in city water system of Smart city:
Smart water global market compound annual growth rate: 14%, 2013 to 2018, including leakage detection businesses (41%), smart meters (37%).
During the 13th five-year plan period, domestic sales of smart water meters shall account for 40% of the total sales of water meters.
Water pressure is the main cause of water pipe leakage ,caused by the Municipal water leakage each year reach to 10.2 billion tons, However, regular pressure correction accelerates the leakage of water.
Nexus says 10 percent of the 20 trillion kilowatt-hours of global energy consumption goes to water transportation.
Problem/Opportunity
IoT (Internet of Things) in pipelines including in buildings is BIG.
1 billion smart meters to be installed by 2020, then:10 billion smart meters/ sensors x $100 each= $1 trillion market.
PROBLEM: How do they better get energy to operate? for battery recharges the problem is:The cost of replacement of the batteries every few years is high. If the batteries cannot be replaced in time, there is a risk of system failure.
Energy for smart city water sensors / meters
Solution : Miniaturized flow turbine genset
2X efficiency, 1/2 starting speed of competiors,
That mens:
1)Same power with half the size
2)More sensitive. Better certainty that the sensors always have electricity
3)No battery replacement labor and cost
4)Low cost, with a long product life
5)Platform for integrating the industry
6)Distribution to sensor/ meter suppliers, contractors, globally
Business Model: " Intel Inside"
Power From City Pipes: Transfer pipe pressure into energy
Excess pressure in municipal water piping systems usually handled by pressure breakers---problem also for oil and gas
Pressure leads to leakage and causes a need to pump harder, which increases pressure
Wasted Energy From Leaks and Lost Water
We make these problems into energy
The electricity generated by pipe pressure can be used in the grid or by the water utility
Leviathan turbine hydro-electric intelligent system is of great significance to water system——Save water and power
Leviathan turbine hydro-electric intelligent system completely solves the problem of water pressure in a municipal pipeline, while utilizing excess water pressure to generate electricity. Where the water system pressure is too high, there can be small-scale hydropower generation. The turbine equipment of the system can be used as generator, energy storage, pressure switch (this is very meaningful: 400 cities in China have the problem of water shortage. Leakage water from utility can't be recovered.
Target market: municipal water supply companies of 660 cities, 2,500 counties, 30,000 administrative areas. Most municipal water supply systems find it difficult to achieve stable water because the pressure and flow inside the water pipes fluctuate.
Green Hydro without dam - Underwater Turbine:No damage and no secondary pollution to city environment
More ecologically friendly
No damage and no second pollution to city environment
Less costly infrastructure
Less size, same function as dam hydro
No loss of energy by stopping the water
Disruptive innovation using the science of Computational Fluid dynamics to design the components
China's water resources rank first in the 16.7% of total, However, the installed hydropower capacity only 19.3 % of the exploitable capacity. During the 13th five-year plan period, China will further develop small hydropower.
Game Changing Hydrokinetic Power
At least doubles the efficiency of turbines of similar blade size, higher at small sizes and low speeds. Starts at half the water speed. This means hydro projects with ROI of 25-50%.
PPA or cooperate with Hydro companies to develop new projects There are 3,019 rivers over 10,000 KW. Underwater turbines can be used in many small rivers and canals. Already have facilities to transfer large amounts of electricity to the grid.
Underwater Turbine Compares to Traditional Hydro
