The operation of a transportable and self-sufficient renewable energy generator
The need to replace fossil fuels on the planet has driven the development of new technologies oriented to the generation of electricity using renewable energy.
The biggest challenge that must be overcome is to reduce costs and improve efficiency in the generation of clean energy.
In one of my previous publications I shared with you how renewable energy was generated using marine currents, an option without the disadvantages of hydroelectric generation through dams (if you want to know more click here).
In this opportunity, I share information about the operation of a renewable energy generator that it can be transported (boat, plane, etc.) to anywhere in the world where electricity is required. The objective of this technology is to bring electricity to sites that have suffered natural disasters, places where civil construction works are carried out, desert or any area where it is difficult to obtain electricity. It is designed for remote, inhospitable places, war zones, humanitarian actions, isolated areas, campaign hospitals, etc.
Whose idea was it?
It is a project developed by the University of Huelva in Spain with the joint effort of a group of technology and construction companies.
Self-sufficient technology?
The development of new technologies is the key to face current energy problems. There is still a long way to go, but projects that seek to improve existing processes or technologies, making them more efficient and cheaper, are always good news.
This technology is made up of a standard container (measuring just over 12 meters) within which there are 96 photovoltaic solar panels and a robotic arm (18 meters) responsible for deploying the panels and being the mast of a wind turbine.

The novelty (in my opinion) is that when the generator is put into operation (system discharge), the container uses hydraulic bases that are responsible for positioning it on the ground (without the need for a crane). Then the photovoltaic solar panels are moved and deployed by the robotic arm that with the help of two operators (decrease in labor cost), it only requires 5 hours to start it and have electric power immediately (That's efficiency!). The loading process of the system works in a similar way.
Portable electricity
Portable electricity generation is not new. There are equipment, such as the generator sets for example, which currently perform this function. These equipments convert mechanical energy into electrical energy throughalternators, whose principle of operation is based on the electromagnetic induction explained on the Faraday Law .
They require fuel, diesel or gas to operate and its biggest disadvantage is that they expel polluting gases into the environment and produce noise pollution (noise).

This new technology is an improvement of the existing portable models, since it uses solar energy and wind energy to generate clean electricity without producing polluting waste and enduring extreme atmospheric conditions. The power generated is 30 or 32 Kw, enough to supply a village. To supply larger populations, several stations can be placed in series and thus increase their capacity.
How to guarantee continuous electricity supply throughout the day using solar energy and wind energy?
A disadvantage of the use of wind or solar energy is that they depend directly on the climatic conditions, which are always random. To overcome this limitation requires the use of some device to store the energy that allows to have it at hand when needed.
In this sense, the new technology has a gel battery for the storage of energy and to guarantee the continuous supply 24 hours (it is composed of a gelidified electrolyte ).
This battery has 12 years of useful life, allows a high number of cycles of loading and unloading and supports discharges of up to 80% without damage. They are suitable for use in distant areas because they do not require maintenance, they are anti-spills and they withstand high and low temperatures.
It is programmable remotely to make it more efficient
As it is an automated system, it is possible to know through remote monitoring how much electricity is generated, how much is consumed, and how much is stored. Additionally, it can be programmed (also remotely) to be as efficient as possible, taking into account the requirements of the area.
The above is a simple description of the operation of this technology, which in my opinion is efficient and represents a breakthrough in the generation of clean energy.
One additional information
The creators of this technology decided to name it as the goddess of Roman mythology "Aurora " (sister of the sun and moon and mother of the north, south, east and west winds), referring to the use that it makes of solar energy and wind energy.
As I was not sure about the copyright of the images available on the web about "Aurora", here is a video that shows briefly how it works:
