In presenting this paper it is our intention to bring our readers up to date with respect to the recent advances and development of the CARE Technology as well as favorable new cost projections,  technical and manufacturing improvements as well as discuss environmental and social aspects. 

Before presenting our comments with reference to the  CARE technology we  review and offer information with respect to the credibility of this new hydro technology. First, the following is the introduction to the evaluation report of the technology made by the CEFET the energy division of the University of Minas Gerais. It stated:

The floating turbine is the most important discovery for the generation of alternative electric energy for the  immediate future causing no pollution.
We can predict that the use of the turbine for generation will provoke significant changes in social structures , in economic development and with regard to ecological and environmental considerations .
In developed countries its potential can be used to produce hydrogen and in developing countries its potential can be used to provide energy to  where it is not readily available. In both cases it will make it possible to create millions of jobs direct and indirect complementing the world’s economy.

The  CARE technology was subsequently invited to be a Technology Pioneer by the World Economic Forum of Davos in 2010 .

CARE was also invited to participate in the  CIETEC program of the University of São Paulo.
Centro de Inovação, Empreendedorismo e Tecnologia - Cietec 
The technology was recognized internationally by articles published in Business Week, Harvard Business Review  Brazil, Valor Economico, the USA magazine Water Power and Dam Construction www.wterpowermagazine.com by the magazine Pequenas Empresas Grandes Negocios by the Scientific and Technical Advisory Committee (STAC)  and was the subject of TV half hour report by CNN in Spanish.


We take the opportunity to comment and offer some considerations and our opinion with respect to the comprehension of the CARE project since it is to a certain degree, a venture capital risk however of proved technical validity as confirmed above.
We have been questioned as to why we do not present a detailed cost / income  projections and market projections.
The following are considerations on these themes. Especially market projection, which we believe will be more readily understood and accepted by those who understand and feel comfortable with new technologies and venture capital and therefore understand the difficulty to project market size or potential of a new technology, product or service and will understand why we prefer not to invent numbers.
Our ideas and opinions  are based and influenced basically on the work and teachings  Bill Sahlman Professor of Harvard Business School in 1996 who wrote:.
“No discussion of business plans would not be complete without addressing the ubiquitous “proformas” that populate them. Most business writers spend hours on detailed financial projections.  They imagine that a potential investor will pore over the numbers asking a myriad of questions.
Prof Shalman continues: When I first started to study entrepreneual ventures I too turned first to the numbers. Indeed now, if I receive a plan that has five years of monthly projections  I immediately and enthusiastically place it in the circular file beside my desk”.
CARE is presenting to the energy market a new, generating efficient and cost efficient hydro electric generating technology which is in shock with norms existing for the last 200 years. The costs have been estimated and confirmed.  Each unit is relatively similar in technology and design but the size necessary to generate the energy desired and local river conditions are conditioning factors.
Since we are dealing with a new technology which changes conception of almost 200 years of hydro generation the question is how long will it take to become a common source of electric energy and not does it work? To determine the potential of the market each investor should make their own estimate.
We estimate that only for the Amazon region of Brazil 9000 units can be installed.  Project this to the world market!! Naturally to do this it is necessary to understand the principals of the technology and its advantages.
We recognize and understand that the local cultures and political orientation in each society influences and conditions the capacity or interest in seeking or understanding new technologies of a venture capital nature especially when they originate from private enterprise. Perhaps this is the principal motivating force which prompted us to present this paper.


The volume of water that passes through the port (opening) is projected according to the  water conditions and determined by the project design. This flow opening determines the spin velocity which is regulated or determined by the velocity at a rate proportional to the height of the water column. This volume creates a perpendicular hydraulic force or pressure on the surface of the blades attached to the axel of the rotor of the turbine thereby creating the spinning motion of the rotor which in turn powers the generator(s) . 

The size of the opening of the water passage flow is calculated to reach the maximum torque of the energy generator. The intensity of the hydraulic force is related directly to the force in the river flow. Each river and each location has different flow intensity. This is the factor that determines the size of the port opening. The hydraulic force on the blades should be sufficient to produce torque superior to the force required by the generator at full operating or rated power. However, it is necessary before this transformation to reconcile the velocity of the spin of the rotor with the water flow and the torque required by the generator.

The turbines are designed so that the rotor always reaches or exceeds the maximum speed of the generator. Also, its length allows a greater volume of river water to create hydraulic pressure on the blades secured on outer perimeter, thereby obtaining a torque with intensity higher than what is required by the generator at maximum power. Therefore, the excess pressure or surplus maintains the generators at full load or the total installed power even if there is a reduction in river flow. Another relevant factor is that the mechanical loss of the system is minimal, because the generator is directly coupled to the tip of the axis of turbine. For these and other reasons, the CARE turbines are highly efficient generating at least at 80% of installed potential of the generators(s)

The positioning (adjusting the position in relation to the river flow height) of the turbines in the water causes the water to rise in front of them (up river) until it reaches the same height as the turbine support structure  (DRUM). The height of this column is regulated by a steel plate which permits the control or adjustment of the speed of the turbine rotor as well as consequently determining power force to be generated. It is adjusted to avoid flooding of the banks or land mass.

The height of the water column that accumulates in front of a turbine varies according to the equipment installed. Models for small and for large rivers are available. In each case a detailed study of the river conditions is essential for proper planning. The generating capacity is determined by the water flow and the conditions at the point of generation. Generators of 167 kWh and 316 kWh, ideal for irrigation  projects, and up to 5 MW are available. An average of water flow of  9 m³/seg. Is necessary to generate  167 kwh.

The installation of units or units successively down stream increases the potential of energy that can be generated in a determined area always depending on the volume of the river flow, the height of the river banks and the consistency of water volume. 

Among important consideration to properly evaluate the technology is that the mechanical loss is almost nil since the generator is connected directly to the axel of the turbine rotor. For these and other reasons the installed capacity of a CARE Generating system is practically equal to the energy generated resulting in a very satisfactory cost/benefit return ratio.


The potential is only limited by river and climatic  conditions. As we have already stated, in Brazil, in the Amazon region there are potentially at least 9000 potential generating site and perhaps another 9000 in the rest of the country . This is an insight to the size of the world market. Imagine other continents with ample river systems and precipitation.

Significantly units can operate and provide energy to off the distribution network locations be they villages, farming , mining   tourist operations hospitals , learning centers and other economic activities.


In considering the real cost / capital return of a CARE installation in order to compare it with other hydro generation technologies such cost must be calculated based on the  Power Actually or Effectively Generated and not the installed capacity which for  unknown  reasons is internationally accepted. The proper formula that may be employed is the following:

P(Watts) = 0 (1/seg.) x Hman x 9,81 m/seg2 x n
Where P = IS  power in Watts – W
Q =  river flow in literes per second L/seg.
Hman Man metric Height in meters   m
N = Percentage of installed generation capacity

The following is an example demonstrating the impact of the cost of a MW when the concept of Installed Capacity is employed vs. the Effective Generation. The estimates were made based on costs in Brazil in 2009-2010 however budgets developed in Europe during this year, 2013, result in costs especially manufacturing costs   at least 40% lower compared to Brasil due to more efficient manufacturing capacity taxes  and the quality of advanced materials available.

1. According to available estimates in Brazil, the average cost of installing a  PCH is R$5,500.00 per kWh and its effective power generation exceptionally reaches sporadically a maximum of 55% of installed power. Therefore, a PCH with installed capacity of 3,000 kWh or 3MWh requires an investment of R$ 16,500,000.00. The conversion rate at this time is US$1.00 equal to R$1.80,00.(Brazilian currency) The cost of a PCH in reality is almost double considering return on capital since  the investment does not generate the installed capacity.
2. Considering the 55% efficiency of a PCH, the real cost of kWh rises significantly to R $ 9,166.67 per kWh. because for an investment of R$16.5 million, for a 3000 kW generating installation only 1800 kWh are effectively generated . A cost increase of 82%
Note  Recent improvements and sophistication of the energy project conducted in Europe ( by the inventor) during 2013 resulted in costs  at least 35% lower than  those determined in Brasil as mentioned above and with access to material and manufacturing procedures of  exceptional quality . This coupled with the efficiency of generation can bring the cost of a kWh or Mw down 60% or more.
An important consideration is that due to the development program in Europe is now possible to manufacture the sections of a unit in series transport and assemble them at the operation site. Obviously this is a significant cost improvement factor. Air lifting is a possibility for difficult access areas.
A resume; costs are all subject to the location of a unit, geography , local taxes and interests etc.
This   now is estimated at EUR1.500,00 per kWh which includes all of the manufactured  parts, transportation from Europe installation costs including concrete necessary . It does not include local taxes, import taxes . Therefore a rough estimate places the cost at Eur1.2 million to Eur 2.Million .  


A.    The day by day operation can be totally administrated and monitored by satellite / internet which will reflect very favorably on operating costs.
B.    Units can be installed close to consumption point eliminating the need for costly distribution systems.
C.    The time necessary from the moment of selection of the site to entering into operation is significantly reduced  compared to other hydro systems accelerating the time for return on capital investment.
D.    Improvements in the fish runs or ladders have been developed which is an important for consideration environmentally speaking.


Up to year 2004 in Brazil estimates indicate that more than 34 thousand sq kLm were flooded to accommodate the construction of dams and more than a million person were removed from their homes. A cost both social and economic never included in the investment projections.

Since the technology has no negative influence on the environment and  is it water powered, a renewable source, it in no way causes any of the negative effects of a normal hydro energy system nor does it adversely affect river life or the surrounding environment. 
Beside the positive effects for the environment there  are also positive economic environmental returns as we point out as follows:  

1.    Since there is no dam no river matter is blocked therefore allowing for the normal flow of the riverbed material and also as a result the river life and river banks down river from the unit is preserved eliminating recuperation costs.
2.    There is no stoppage time for cleaning and removing accumulated material blocked by a dam. There is no accumulation!
3.    The source of energy is renewable no transportation, or pollution; no danger of oil spills etc.
4.    Obviously no land is flooded no one is removed or ejected from their land or home productive land is not destroyed .
5.    No fuel of any kind is used also an economic consideration.
6.    Fish passages are a part of any installation.
7.    The spinning of the rotor blades serves to oxygenate the water to the advantage of water life.
8.    In flood situations the units can be raised allowing passage of excess water avoiding recuperation costs .
9.    .No buildings are necessary the unit and equipment is self contained signifying less interference in the environment..


The following is a Blog CARE published which is pertinent to pointing out the positive social and economic aspects of the use of the technology especially in areas that are not served by energy distribution nets. It was provoked by an article in the VEJA Magazine, Brazil, of November 4 entitled:  “What do The Indians Want”. It confirms that the Brazilian Indians tribes like any population in any country want a better standard of life and access to health, care, education and the opportunity for economic development and private initiative opportunities.
In order to achieve these objectives it is essential that clean energy be made available to communities off the distribution net work thus creating the conditions essential to economic  and social liberty and evolution. Objectives not always embraced by political interests. These are international preoccupations.
We site a presentation  made  by  Dr  Amulya K.N. REDDY of India published  in the World Energy  Assessment under the following title Energy and the Challenge of Sustainability  an appreciation of the importance of energy for sustainability in  He wrote: the 90’s
“It has been observed that poverty has the face of a woman.” Energy and women are closely connected in many and different forms but principally thru or via the sources of energy (principally biomassa) the characteristics of the family unit, the characteristic of the energy politics and their position in the community .  The availability of energy is the deciding factor and consequently is vital to improve woman’s position in society and in the family. This conception is daily becoming more accepted as the fundamental factor to understand the reasons for the poverty that dominates in certain areas. The author is convinced that many of much of the work load that falls to women could be alleviated if there was ample access to electric energy.
The presence of a very large number of family members that are normally the responsibility of a woman in the great majority of underdeveloped countries and because of the fact their responsibilities / and activities are intimately related to the search for and administration of sources of energy is what creates this connotation. It is for these reasons the risk of poverty is greater for women.
It is fundamental that we face this situation thru a different prism : It is essential to recognize that the availability of energy and I its consumption is not in its self an objective. The human being does not want coal, oil or generators; they want what these sources can provide in the form of energy.
