The vehicle must be in thrust on an axle with a bent fork, which with its load creates energy that moves the vehicle. This way of starting the vehicle reduces CO2 emissions into the atmosphere. Energy for starting would be generated on the basis of electronics and generator drives and solar collectors would be used.
Combustion of fossil fuels produces gases that are major pollutants on a local and global level. The use of force as driving energy in vehicles could significantly reduce the emission of harmful gases produced by burning fossil fuels. To start the vehicle, thrust, i.e. weight, and solar energy would be applied, which would contribute to reducing the use of fossil fuels.
The use of gravity for driving energy is shown in the attached sketches.
