Just to give you an idea. Our car, your car, my car is a 12 volt car with a 12 volt battery. A fuel seller producing electricity, but not 12V, 700 volts. This number of voltage, this, this power, we have to transform it a part from the engine of the car and the other part for the GPS, the road books, the lights, the windscreen, heater. You can't have a better try than a race like that car. That's why all these components we, which is already, fixed on the car will, will work, will do their job and we will realise that especially because of the quality of the air with a lot of silicium inside, because of the desert, to see if they can keep going or do we need to go to another component.
