Their operation is based on the consumption of vegetable oils in Internal Combustion Engines, ie conventional diesel engines that have been tested for their performance during operation and their longevity, using them to generate electricity while exploiting the heat produced. All known vegetable oils (sunflower oil, soybean oil, cottonseed oil, etc.) but also the less well known such as rapeseed, and palm oil can be used.
For the production of electricity from liquid fuels is used a PC (generator pair) consisting of a diesel engine and a generator. With the necessary technical factory modifications, the diesel engine can use vegetable oils for fuel. In fact, this idea is not recent, since the original engine design by Rudolf Diesel foresaw the use of vegetable oils. It is a soundproof system and is automated as it controls both the power supply and the operation of the unit while there is remote monitoring from the system control center.
Vegetable oil e.g. rapeseed oil could be described as 'total ecological fuel', since its use pollutants are emitted at a level well below the European Union's minimum standards, according to international measurements. Pancakes can also be used as fuel in the specially modified diesel engine after use. Pancakes are hazardous waste and require special management after collection. Using pans as a fuel not only minimizes the cost of managing them, but also uses them to generate energy.
