Question: Watt happens when the Volt runs low on Amperes? Ohm my!
Answer: The battery gives out.

That word play reminds us of electricity 101.

Those four familiar units of electrical measurements are derived from the names of pioneers and scientists never to be forgotten: James Watt (1736–1819), Alessandro Volta (1745–1827), André-Marie Ampère (1775–1836), and Georg Simon Ohm (1789-1854)

A fifth name belongs with the above: Nikola Tesla (1856-1943), a relative newcomer in terms of history and recognition. Then again, his time has arrived and he will be remembered by the fine battery electric vehicles (BEV) from the corporation bearing his name; His accomplishments in the science and application of many things ‘wireless’ are less well-know.

General Motors has named its EVs after two of the above pioneers, Volt in North America, and Ampera its European twin built at Opel in Germany and Vauxhall in Britain.

What about Watt? Not a thing is named in his honor; We are paying dearly for that omission, every month on our electricity bill - by the kiloWatt, while Yogis everywhere chant “ohmmm”.

Seriously now, although comfortable with electricity, the dreaded range anxiety still prevents some motorists from buying a car with an electric motor and its advantages. The obvious disadvantages are to blame not on the car, but on the battery.
The battery is older than the automobile, but has undergone little improving before the return of the electric vehicle (EV), presently experiencing painfully slow but promising progress in the battery department.

To afford motorists the possibility to cross countries or continents, - before the ‘500 mile battery’ arrives-, inventive chaps are developing the “battery in a box”.

The hitch? You need one.

Tiny trailers containing a larger-than-in-the-car battery can be picked up near restricted highway on-ramps or at service centers along the way. Others types of trailers carry a smaller, lighter battery along with a generator (range extender) to keep the battery charged. (Some people do not want to let go of the internal combustion engine).

We have forgotten that one hundred years ago travelers had to be on the look-out for petroleum stations as keenly as EV drivers now have to keep an eye on their Amp-gauge for charging stations along their way.

What comes first, the chicken or the egg?

Towing an Ebuggy trailer behind the EV? Does the trailer not usually come before the case in point? (at least in Holywood)
No one ever said progress makes sense.
