Simple Efficient Useful Technologies.

http://www.tinet.org/~sje/index_sp.htm Spanish.


Our Mission.

The purpose of the creation of this site, is to promotion Useful, Simple and Efficient Technologies and applications that let's obtain a More Free Live. Freedom that is not possible without more respect to ourself and to our planet earth.

Do you know the danger of Nuclear Energy and Pollution of Burning Fuels. By this, we need begin to show more respect to our planet earth and to ourself. Reduce as possible the use Nuclear Energy and Burning Fosil Fuels.

To live with dignity, we need change to use the Renewable Energies, as the Sun, the Wind and the BioDiesel.

Sustenable Energy Sources.

Wind Power Generators. This is the most interesting of the sustenable energies sources that I know.


Sustenable Transportation.

When we want to show more respect to our planet and life, we need reduce the contamination production as possible. Here do you have some ways to do it.

Magnetic Fuel Saver and Other Fuel Savers. How to use permanent magnets to obtain more power and fuel consume reduction in your vehicle and general burners, by improving liquid fuel combustion.

Biodiesel. The Biodiesel is the fuel that you can produce yourself for any diesel engine or heater. Now, you can make your own fuel from vegetable oil that takes only minutes. With this we can stop our petrolium dependecy and obtain a more cheap fuel and more freedom.

Hibrid Vehicles. This type of vechicles have two motors, an electric motor and a fuel powered motor, one for each working conditions, the electric motor for city and the combustion engine for road. You can find this type of vehicles in the market from manufactures as Toyota, Honda and Ford.

Electric Vehicles. These are the zero emission and silent vehicles, that are only sustenable if we recharge their batteries with eletrical energy from the Sun or from the Wind. We can NOT use eletrical energy from a Nuclear Plant if we want a realy sustenable electric vehicle.

Electric Vehicle Design and Construction. Race Car, Aerodynamics, Chassis, MotorCycle Design, Electric Vehicles, ...

Air Car or Compressed Air Vehicles. Cars powered by the energy stored in their tanks for compressed air. EnergyAir Research & Development. Angelo Di Pietro. Pneumatic Hybrid Electric Vehicle.


ElectroMagnetism and Renewable Energies.

Another way to show more respect to our planer earth, is the use of electricity obtained by renewable means ( Sun, Wind or BioDiesel ). In this section I will try to show you the most insteresting ElectroMagnetic technologies to obtain a More Freedom Life.

Now, that we know more about the effects of Electricity and Magnetism over our Health, we can go to learn more about ElectroMagnetic Applications to design or redesign it safety, with benefit over our health and protection from the dangerous effects. The First step is going to design a more energy efficent transformers, electric generators, and motors to obatin a more economic and ecologic designs of wind powered electrical generators, and more efficent and sustenable vechicles.

The most important device for Energy Generation is the Electric Generator, this device is used in all techniques of electrical energy generation, including nuclear, hidraulic, and wind. For this reason is very important our understanding of their working principles and the properties of ferromagnetic materials.

But we need start by coils, then go to a more complex device, magneticaly coupled coils, usualy named transformers, and then go to electric generators and loaded electric generators.

Simulation of Non Linear Inductor using Beige Bag Spice Software. Here do you have the model to obtain a quality simulation of a Non Linear Inductor, by saturation of magnetic material. I will try to show more details about this model and how to use it.

Simulation of Permanent Magnet AC Generator with FEMM, and Lua Script. How to create a 2D Finite Element Animation, Simulation of Open Circuit Voltage of a Permanent Magnet AC Generator, etc ...


Power Electronics and Renewable Energies.

Power Electronics. This section is very important in the use of renewable energy technologies, because we need the use Power Semiconductors to build:


Development Tools.

Digital Scope to SciLab. In this PDF document do you have a description of a method that let you load sampled data using a Hameg Digital Scope, into SciLab. Where we can manipulate this data with the other SciLab matrix manipulation functions. This will help us in analysis and development of our prototypes.

Sci2Vtk. A set of SciLab functions that let you save SciLab data in VTK files that you can visualize using the Free software named ParaView.

MatLab2Vtk. A set of MatLab functions that let you save MatLab data in VTK files that you can visualize using the Free software named ParaView.


Practical Applications.

Router Laser CNC. DiY. How to build a Router Laser CNC.

Reusing Fluorescent Ligth Tubes.( Only in Spanish ) The purpose of this porject is to study the reusing the fused fluorescent ligth tubes. As is possible that appliing 600 volts we can run fluorescent tubes that don't work with classic system.

Charging Batteries with Solar Energy. ( Only in Spanish ) In this page do you have a practical use of photovoltaic panels to charge batteries with the energry from the sun.


Self-Sufficient, Ecologic and Sustenable House.

This is the more important project in this site. A 100% Self-Sufficient House. But to do it, we need learn new subjects. From sustenable Electrical Energy Generation, to Permaculture.

Is NOT possible a life in Freedom when we worry about our needs ( food and house ) and to maintain it.

For this reason, in this section, we will try to use as well as possible, our knowings about how the natures works, to obtain all that we need to live in peace without external requirements. This is: food, water and a comfortable place.


"Electric power is everywhere present in unlimited quantities and can drive the world's machinery without the need of coal, oil, gas, or any other of the common fuels."

Nikola Tesla


"Only from the alliance of the one, working with and through the other, are great things born."

Saint Exupery (tr.1948)
