In this article, you will discover one of the main applications of the Thermoambient Generator.

Electric car powered by thermoambient energy

In the very near future, electric cars will be equipped with a thermoambient generator that will convert air thermal energy into electricity to power their motors.

Unlike today's electric cars, new electric cars won't have to stop to recharge their batteries. Especially during summer, the energy extracted from the ambient air will be sufficient to provide 100% of the electricity the car needs to get around.

The new electric propulsion system will work as follows (see figure 1):

  1. The internal combustion engine will be replaced by an electric motor (item 4).

  2. The radiator of the car will be replaced by a heat extractor (item 1). The extractor is the opposite of the radiator. That means, instead of releasing heat into the atmosphere, the extractor will absorb the heat from the atmosphere and send it to the thermoambient generator. The generator, in its turn, will convert the heat into electricity and power the motor of the car.

  3. Between the heat extractor and the generator, there will be a gasoline heater (item 2) that will automatically activate when the ambient temperature is below 0°C. Its function is to keep the thermal fluid at the minimum temperature necessary for the perfect operation of the generator.

  4. The thermoambient generator (item 3) works by exploring, in an innovative way, the thermoelectric phenomenon called Seebeck. The generator converts the ambient heat into electrical energy and feeds the motor and other electrical parts.


A popular 1.6 cc car with 106 hp, for example, will produce a drop of 5.3°C in the temperature of the air passing through the heat extractor. This amount of heat in the extractor would be enough to generate the 106 HP (78 kW) used by the car. The calculations shown below were made considering the car moving at 80 km/h.

Let's move on to the demonstration:

We will use the Mass Flow Rate formula and the Heat Formula to calculate the required temperature drop to obtain 106 horsepower.
equation_1

Where:
m=
mass of air passing through the heat extractor in g/s;
ρatm=
specific mass of atmospheric air = 1.225 kg/m3;
Vair=
air velocity in the heat extractor: 80km/h = 22.2m/s;
Aext=
air intake area in the extractor: 0.90 x 0.60 = 0.54m2;
Q=
amount of heat in calories;
c=
specific heat of atmospheric air: 0.24 cal/g.°C;
ΔT=
temperature difference in degrees Celsius.

Knowing that 1 cv = 735.45 W, and 1 W = 0.23884 cal/s, then: 106 cv = 106 x 735.45 x 0.23884 = 18,619.417 cal. Therefore, for purposes of our calculation Q = 18,619.417 cal.

Calculating the mass of air m that passes through the heat extractor every second, we have:

Calculating the temperature difference in degrees Celsius, we have:
equation_3


As shown above, by withdrawing thermal energy equivalent to 5.3°C from the air passing through the heat extractor, we obtain enough energy to power the 78 kW (106 hp) of the example car. This makes this car self-sufficient in tropical climate regions. In very cold regions, where it is not possible to extract 5.3°C from ambient air, the required heat will be complemented by the thermal energy of the reserve (emergency) fuel.

In addition to the energy of this car having zero cost, the most important thing is that it does not add heat to the environment or pollution to the atmosphere, thus reducing global warming.
