Alternative energy sources for use in an electric car

The electrochemical batteries or fuel cells in electric vehicles, at present, need to be charged frequently and the charging could only be done at charging stations. This means that the vehicle has to be temporarily not on the move. Could it be possible to charge, if not all, some portion of the batteries or cells requirements? Could it be done while on the run? This work investigates two possible techniques of providing such "on the move" charging. One is by making use of the wind opposing the vehicles' thrust and the other is by employing heat difference available in the vehicle; that is by principle of thermocouple. Several schemes of tapping the energy sources were investigated in this work.
