New, High Potential Influence On The
HYDRO ENERGY Industry
It is a rare opportunity to see an official hydro industry related news with content of potential influence on all hydro energy generation fields such as: large-, small-, and distributed hydro developments.
Just recently surfaced such a subject:
The Canadian Intellectual Property Office (CIPO = Canadian Patent Office) issued a patent on August 6th, 2019 (patent number: CA 2,978,935) for a totally new hydroelectric power generation method, which was found industrially adaptable for LARGE (dammed), SMALL-SCALE (run-off-river) and DISTRIBUTED hydroelectric projects, as well.
This new invention is called: COHESION BASED HYDROELECTRIC POWER.
This innovation appears to have actual potential to solve numerous current hydro energy related problems. One of the most important for all hydro projects is the HYDROLOGY related subjects. In other words: the problem of water flow-rate fluctuation by the seasons of the year – which is one of the most serious problems evaluating any new, or desired development sites for continuous power generation potential being calculated either in watts, or in dollar value.
To declare that hydrology problem can be solved by an innovation ... – this is by itself a rather surprising statement.
What’s going on?
… did somebody invent a method how to control nature itself?
… or, how to influence rainfall? – making water flow-rate in rivers controllable by humans?
Well, yes - almost, but not exactly!
The situation is that more-or-less we still follow the basics of what the Romans taught us more than 2,000 years ago, how to utilize the capabilities of MOVING water.
… but the Romans didn’t know that the equation of kinetic energy is:
Ek = (m x v2) / 2
It shows us that double speed creates 4 (FOUR) times energy. But… at the same time, double speed draws double volume of water in the same piping, therefore the double water speed actually produces 8 (EIGHT) times kinetic energy!!!
In our times engineers know this very well, that’s why:
- they build high dams to increase water head (height) for large projects,
... and that’s why:
- they look for fast running river sections for smaller scale energy generation projects.
How nice would it be if we could increase the speed of the water ANYWHERE without investing even more capital into our already rather expensive hydro project(s)!
“It is impossible!” – engineering people would say - because, to move water faster requires energy input, and energy costs money!
The engineers would be correct with the first half of their argument – “moving water faster requires energy"
But there is a way to make that energy input FREE OF CHARGE!!!
Just we have to move the design focus from the PENSTOCK (water intake) over to the TAILWATER AREA (water return to nature).
- in other words: from BEFORE the turbine to AFTER the turbine!
- or, yet in other words: generate on-site kinetic energy, instead of looking for, and using the already existing potential energy of the water!
This new Canadian hydrogeneration method utilizes MOLECULAR COHESION FORCES OF THE WATER – simply by applying the well-known SYPHON EFFECT!
Oh Lord! It sounds so scientific!
Yes, it sounds!
But actually, it is not!
Anyway, to make it more understandable, simply think about the situation when you drink Coca Cola from a can by a plastic straw.
When you suck on the straw you create vacuum with your mouth at one end of the straw. The air pressure at the other end will push the Coke upwards in the straw, out of the can, into your mouth. The cohesion force of the water molecules keeps the water in the straw “continuous” without any break in the fluid line.
This “fluid moving effect” works downward direction, as well.
But downward – instead of making vacuum by sucking – we utilize the force of gravity in the “straw” (in multiple pipes!) to pull the fluid downward FASTER THAN HOW IT WOULD FALL BY ITSELF!!!
This way any water – standing, or very slow moving – anywhere above sea level, can be brought into controlled motion.
The volume and speed of the water depends on various influential factors apart from elevation difference (called: water head), such factors as:
- the diameter,
- the length,
- and the number of the downward pipes (called: COHESION PIPES).
In this case the elevation difference between water-intake and water-outflow (water head) is a secondary factor – because installing more cohesion pipes will increase the speed of the water – resulting in the same energy generation increase as increasing water-head, or elevation difference do in current hydro plants.
As a matter of fact, installing more cohesion pipes is a much more economical (cheaper investment) than building high-higher dams!
In other words: we can make CONTROLLABLE AT-WILL all influential factors what “water head” would produce.
Its time to let your professional hydro imagination fly free:
– what does this “AT-WILL CONTROL” mean?
- what results can be achieved?
- and what kind of numerous hydro problems can be solved, or at least substantially reduced – be it technical, financial, social, and even political subjects?
Let’s mention but a few:
- HYDROLOGY: effects of “dry season of the year” is eliminated – as long as some water is still available.
- GEOLOGY: the requirement for “civil works” on the project substantially reduced.
- POWERLINE: new, potential sites can be discovered near to already existing power lines.
- SOCIAL / POLITICAL: no interference with the local social circumstances, no residential relocation required, therefore easy acceptance by the local community, - resulting in less political resistance from the government.
- ENVIRONMENTAL: no water reservoir, or dam is needed. Therefore, the environmental
influence is almost zero. This fact will make the required governmental
licencing procedures easier and faster.
- CIVIL WORKS: as the powerhouse actually can be placed at any location, civil works
requirement is substantially reduced
Based on the above it is evident that the required financial investment and the required construction time both will be substantially reduced for any new hydro installation, or any existing power plant upgrade, as well.
The only required, newly developed part/component may be a turbine assembly designed for both: changing water velocity and varying water volume! Turbine manufacturers already working on the development of such units for different level of energy generation.
The opportunities for establishing new electric power generation as new run-off-the-river generating stations will grow very fast – because geographical locations earlier identified as unfit for hydro generation purpose - will now be identified as proper, economical, environment friendly potential installation sites.
Further more it is now economically possible:
- to upgrade already existing hydroelectric dams to generate more electric power using the same, or even less water volume …
- to upgrade already existing non-powered dams to generate electric power without the need of large civil work…
Actually, we are talking about a potentially effective solution to reduce the reasons of global warming – at the same time to generate substantially larger electric energy without even having any influence on the environment.
This Canadian patent is already in the administrative procedure at the WIPO (World
International Patent Office) in Switzerland for an international patent approval with a retroactive
PRIORITY DATE of September 12th, 2017.
Therefore, this Canadian patent is already here to serve the hydro industry of the world in any country,
… but most importantly: the entire human population!
