Engineering point of view.......



So......what do you think ? 🤔


INTERESTING - ONE OTHER QUESTION. IF ELECTRIC CARS DO NOT USE GASOLINE,
THEY WILL NOT PARTICIPATE IN PAYING A GASOLINE TAX ON EVERY GALLON THAT
IS SOLD FOR AUTOMOBILES, WHICH WAS ENACTED SOME YEARS AGO TO HELP TO
MAINTAIN OUR ROADS AND BRIDGES. THEY WILL USE THE ROADS, BUT WILL NOT
PAY FOR THEIR MAINTENANCE!

In case you were thinking of buying hybrid or an electric car:

Ever since the advent of electric cars, the REAL cost per mile of those
things has never been discussed. All you ever heard was the mpg in terms
of gasoline, with nary a mention of the cost of electricity to run it.
This is the first article I’ve ever seen and tells the story pretty
much as I expected it to.

Electricity has to be one of the least efficient ways to power things
yet they’re being shoved down our throats. Glad somebody finally put
engineering and math to paper.

At a neighborhood BBQ I was talking to a neighbor, a BC Hydro executive.
I asked him how that renewable thing was doing. He laughed, then got
serious. If you really intend to adopt electric vehicles, he pointed
out, you had to face certain realities. For example, a home charging
system for a Tesla requires 75 amp service. The average house is
equipped with 100 amp service. On our small street (approximately 25
homes), the electrical infrastructure would be unable to carry more than
three houses with a single Tesla, each. For even half the homes to have
electric vehicles, the system would be wildly over-loaded.

This is the elephant in the room with electric vehicles. Our residential
infrastructure cannot bear the load. So as our genius elected officials
promote this nonsense, not only are we being urged to buy these things
and replace our reliable, cheap generating systems with expensive, new
windmills and solar cells, but we will also have to renovate our entire
delivery system! This latter "investment" will not be revealed until
we're so far down this dead end road that it will be presented with an
'OOPS...!' and a shrug.

If you want to argue with a green person over cars that are
eco-friendly, just read the following Note: If you ARE a green person,
read it anyway. It’s enlightening.

Eric test drove the Chevy Volt at the invitation of General Motors and
he writes, "For four days in a row, the fully charged battery lasted
only 25 miles before the Volt switched to the reserve gasoline
engine.” Eric calculated the car got 30 mpg including the 25 miles it
ran on the battery. So, the range including the 9-gallon gas tank and
the 16 kwh battery is approximately 270 miles.

It will take you 4.5 hours to drive 270 miles at 60 mph. Then add 10
hours to charge the battery and you have a total trip time of 14.5
hours. In a typical road trip your average speed (including charging
time) would be 20 mph.

According to General Motors, the Volt battery holds 16 kwh of
electricity. It takes a full 10 hours to charge a drained battery. The
cost for the electricity to charge the Volt is never mentioned, so I
looked up what I pay for electricity. I pay approximately (it varies
with amount used and the seasons) $1.16 per kwh. 16 kwh x $1.16 per kwh
= $18.56 to charge the battery. $18.56 per charge divided by 25 miles =
$0.74 per mile to operate the Volt using the battery. Compare this to a
similar size car with a gasoline engine that gets only 32 mpg. $3.19 per
gallon divided by 32 mpg = $0.10 per mile.

The gasoline powered car costs about $20,000 while the Volt costs
$46,000-plus So the American Government wants loyal Americans not to do
the math, but simply pay three times as much for a car, that costs more
than seven times as much to run, and takes three times longer to drive
across the country.


Please note , I have not researched these comments I only pass them on
