Looks interesting. I suppose the benefit(s) derive from timing.
In essence, generating electricity from rotation and then reconverting it to rotational output involves inefficiencies, however removing the parasitic drag of the pulley drives restores some of the losses. Electrical drag is easier (and quicker) to switch on (and off).
I'm surprised that there is no (additional) electricity storage, but rectifying alternating current (as generated by alternators) into direct current involves energy losses. It is better to use energy 'immediately' (and only generate it when required). Whilst mechanical drives can be clutched, the basic belt-and-pulley drive absorbs energy even when 'idling'. The parasitic drag of an in-line alternator when off-load is minimal.

Thanks G-CPT, and may I just add, The angle of the dangle, is directly proportional to the velocity of the monstrosity minus the gravitational influence of the alcoholic fuel.

This can be ameliorated to some degree, by the fitting of new bushes, or even a little general refurbishment, like new rings in the bore, or a complete body overhaul.

Failing that it is a new model I'm afraid. Lol
