    New fuel cell design powered by graphene-wrapped nanocrystals

    According to an article in the NewsDay Weekender publication in Zimbabwe

    TWO Harare-based engineers have invented a simplified hydropower engine and pump for electricity generation. According to the engineers, the invention does not need a lake, river or a dam to run unlike other common hydroelectric power plants. The plants are run using water tanks mounted on tall buildings. “Between water tanks, we set our turbines, which together with other internal systems, are powerfully set in motion by the water,” one of the inventors, Edmas Gozo, told NewsDay Weekender. “Unlike in other common hydropower plants, the water is not wasted away, but keeps rotating in the systems of our new power model, as it infinitely generates electricity.”

    Gozo, an electrical engineer by profession, and Jeremia Sundire, a water engineer, started working on the model in 2010 and emerged with the complete concept in 2013.The engineers launched the invention in Harare on Tuesday, where demonstrations were held at an event attended by representatives from the Ministry of Energy and Power Development.

    This where I have a problem “Unlike in other common hydropower plants, the water is not wasted away, but keeps rotating in the systems of our new power model, as it infinitely generates electricity.”The FIRST LAW OF THERMODYNAMICS ( also know as the law of conservation of energy) states: the total energy of an isolated system is constant; energy can be transformed from one form to another, but cannot be created or destroyed. So you have to always ask the question “where does the energy come from”?

    I received an email from one of our readers suggesting the tanks could be filled by rain. If this is the case then it would be possible to obtain some electricity on an infrequent basis. However if it is an elevated header tank then the question has to be asked where the energy comes from to refill the tanks.

    The article goes on to report: The inventors were now looking for investors to turn the project into a commercial venture, which the say can produce 300 megawatts of electricity.“Three hundred megawatts of electricity is our average production, but we can produce more electricity using our invention depending on the demand. We will be able to produce energy not only for Zimbabwe, but for the whole of Sadc,” Gozo said. But the engineers said this was only possible if investors supported the programme.“We need investors to help us produce a prototype for exhibition at international energy expos. What you see here, although running as you can see, is a dummy of our actual concept,” Sundire said.


    The invention is now registered with the World Intellectual Property Organisation (Wipo) under application number PCT/AP2011/000003.;jsessionid=797271C5D834568A50557BFA418DF5DE.wapp1nB?docId=WO2013029065&recNum=1&maxRec=&office=&prevFilter=&sortOption=&queryString=&tab=PCTDescription



    The invention provides a pump which is also an engine, powered by water, to pump liquids containing suspended particles. The system comprises a set of pipes (29) driven in a reciprocating movement by a crankshaft (28) attached to a shaft (35) driven by a speed gear (34) which also is driven by a hydro turbine (20) powered by a hydrant pipe (21), which gashes water against a hydro-turbine, from member (36).

    Many known pumps are driven by fuel engines, some by electricity, or manually driven. The world relies mainly on fuel engines and electricity. Main problems found on fuel engines are fuel price hiking, emissions of dangerous gases in the air like carbon monoxide from petrol engines, carbon dioxide from diesel engines. When electricity is used, high percentage of polluting the air is expected from coal power stations, high bills of money are charged e.g to those operating irrigations, also power shading is to be expected any time. All these problems are found to people running their pumps with fuel engines and electricity.

    We also have many pumps which are manually operated, which demands one to be fit to operate it. Some need more than one person to operate , thus leaving other jobs unattended to, and its already a problem. But this hydro-engine and pump is fuel and electricity free to run, because of its system which is driven by water . Therefore it solves all the above problems found in the pumps driven by fuel , electricity and manual engines, thus solving the world’s problem.

    One object of this invention is to provide a pump run by a water-powered engine which is able to pump liquids containing suspended particles and is able to maintain such particles in suspension. The second object is to provide a water -powered engine which can drive pumps and electricity generators.


    Anything is possible and hopefully they may be on to something, I need a bit more convincing or understanding of what they are trying to achieve. I think a working proof of concept is needed and taht this is peer reviewed.
