A family car needs about 10kW of power. This is not a large number. A 65x1cm steam plasma tube at 4 atmospheres produces 580kW. You can purchased a small generator over the internet for under $520.
The thermoelectric [anels to supply us will 50kW of power?
Thermoelectric moduleA thermoelectric module is a circuit containing thermoelectric materials that generate electricity from heat directly. A thermoelectric module consists of two dissimilar thermoelectric materials joining in their ends: an n-type (negatively charged); and a p-type (positively charged) semiconductors. A direct electric current will flow in the circuit when there is a temperature difference between the two materials. Generally, the current magnitude has a proportional relationship with the temperature difference. (i.e., the more the temperature difference, the higher the current.)
In application, thermoelectric modules in power generation work in very tough mechanical and thermal conditions. Because they operate in very high temperature gradient, the modules are subject to large thermally induced stresses and strains for long periods of time. They also are subject to mechanical fatigue caused by large number of thermal cycles.
Thus, the junctions and materials must be selected so that they survive these tough mechanical and thermal conditions. Also, the module must be designed such that the two thermoelectric materials are thermally in parallel, but electrically in series. The efficiency of thermoelectric modules are greatly affected by its geometrical design
So read https://en.wikipedia.org/wiki/Thermoelectric_generator. The thermoelectric device is opnyl 4% efficient – wheras the steam trbine is going to be about 40%. The thermoelectric panel is 1/3rd of eh cost.
The steam plasma tube will use 10-18cc of regular water in 3 years, and wil lsupply an excess of heat. No stopping to refuel – ever.
So rather than a bettery, we can use a steam plama and thermoelectric panel – 10% of the weight of and engine and gear box/transmission. And a lot smaller.
The commercial value is so huge – the first car maker who sell a steam plasma car is going to destroy petrol cars. And it is 1st year undergraduate engineering.
