Does the ENERGIESTRO set produce free energy?
Top

In a certain sense yes, because cogeneration recovers heat that is usually lost.

 

 

 



 

What is cogeneration?
Top

Conventional gen-sets and power plants have a global efficiency of 30 - 40 %, meaning that 60 - 70 % of the fuel is wasted as heat dumped in the environment. Cogeneration (also called Combined Heat and Power or CHP) consists in using this heat instead of dumping it. But since heat is harder to move than power, cogeneration is possible only if power is produced locally, at the building. Thanks to cogeneration, more than 90 % of the fuel can be used, which considerably reduces consumption, and consequently operating cost and carbon emission.

 

 

 

 

 

What are biofuels?
Top

Biofuels are the various fuels produced from biological processes, like agriculture and waste treatment. They have numerous advantages over fossil fuels, in particular they produce much less GHG (glasshouse gases). Biofuels are a sustainable solution of world energy problems, in that they are renewable (they are actually solar energy stored in chemical form), economical (their final cost is nearly that of fossil fuels with taxes) and very abundant.

The ENERGIESTRO set used with a biofuel is a true renewable energy, like solar and wind energy, but more economical and practical.

The standard ENERGIESTRO set can be used with two biofuels:
- Pure plant oil;
- Biodiesel (fatty acid ester), which is a normalized fuel.

Depending on demand, we will develop ENERGIESTRO sets adapted to other biofuels: biogas, ethanol…



 

 


How does a flywheel store energy?
Top

A flywheel stores energy as "kinetic energy", which is the energy of a moving mass. For instance, a moving car has a certain amount of kinetic energy, as it may cover some distance freewheel with its engine idle. The ENERGIESTRO set stores energy by spinning its flywheel.

 

 

 



Is the ENERGIESTRO set noisy?
Top


The ENERGIESTRO set is thoroughly soundproofed, so that it does not create any discomfort and respects regulations. A super silent version is available as an option.

 

 

 



When will it be possible to buy an ENERGIESTRO set?
Top

Starting from the end of 2010, with the first model 6 kW powered. A system designed for such a long life must undergo an exhaustive validation program before commercial launch.
