Question – What is the main idea of your invention?
Answer
– The main idea of our invention is a new and efficient way of utilizing energy of water waves. This is one of the important problems in modern technical science.


Question – What are differences of your invention from other ideas and models in this field?
Answer
– Our version is different from all existing ideas and models known to us by simplicity of technical implementation: imagine a cable, one end of which is attached to a buoy on the sea, and the other end stretches to the shore. This cable runs in the same direction as the waves, floats on the water’s surface, and can rotate around its own axis. Under these circumstances, we can transfer the mechanical energy of the water waves to the shore.

 

Question – What rotates the cable?
Answer
– A rotor with flexible fins attached perpendicularly to the axis – let’s call it a turbine for our purposes. Such a turbine would be turned either by the forward or backward motion of the sea waves. Many such turbines together can convert the energy of waves into other useful types of energy.

 

Question – What are the advantages of your version compared to already existing models?
Answer
– This model is much simpler, more stable and cheaper than any previous models known to us. Our idea can be thought of as on the new path for development of floating turbines.


Question – Could you please indicate concrete advantages of your model in more detail?
Answer
– There are several of them:

  1. Usually other such models utilize energy of a single wave during a particular phase of wave motion. In our model all waves along the length of the cable (length of which can be hundreds of meters) transfer part of their energy to the cable.
  2. Any mechanical turbine needs to be rigidly attached to something, which creates additional technical complications. Our model is freely floating on a surface of water, so there are no difficulties related to stabilizing the turbine.
  3. One of the significant problems of similar systems is the transport of the energy from the sea to the shore (by the electric cable on the bottom of the sea, for example). In our model, energy is naturally delivered to the shore for further utilization.

Question – What amount of energy can be generated by your model?
Answer
– We’ve only created a lab model of one turbine, which confirmed the validity of our idea. As for the amount of energy – it depends on the type of the material used for the cable, the type of waves etc.


Question – Are you going to create a working model?
Answer
– Unfortunately, we don’t have enough resources right now, but if we can find funding, we would easily be able to build a working model.


Question – Is this problem being scientifically studied right now?
Answer
– Unfortunately, no. Our country still has a number of well-qualified scientists in this field, but there is basically nothing available in the way of laboratory facilities and financial support. Right now we have access to only one modest experimental device in Tbilisi State University, when some twenty years ago there were around 30 wave-making lab devices throughout Georgia. It is no secret that without substantial financial and technical support it is impossible to achieve any important scientific goal.


Question – What will happen with the idea of your turbine, what are you going to do in this respect?
Answer
– For now, we can only publicize our ideas through the internet. According to Paris Convection, our group is at the top of the list to get a patent for our model during one year in 100 countries. If any person or organization has interest in our idea, we are ready to pursue further research and create a working model.
