Electric cars are crap...



Out here in Hawaii, a majority of our electricity is generated by fuel oil at the local HECO Plant, but we have some people saying that they drive a electric car because there carbon foot print, blah, blah, blah.

Reality is, that on the islands, they're idiots.  My jeep probably has a smaller "Carbon Footprint" than their smug mobiles cars.

The fact is, when you convert energy, you produce heat as a waste product.  Not to mention the amount of environmental damage to produce the batteries, which might last 5 - 10 years (think mining the ore, transporting the ore, refining the ore, making the battlers, transportation of the batteries  for final assembly of the car, and lastly disposal of the dead batteries).

Also, have fun paying for the replacement batteries ($15000 - $30000) vice a new engine ($2000)

For over 100 years, we have been using Lead Acid batteries in everything from submarines to cars and the technology is relatively mature.   Lithium Ion batteries, not so much.  For proof google "Lithium Ion Battery Fire", only 2,750,000 results.  Lead Acid Fires only returned 1,700,000 results, but we have been using them for over 100 years.

As for greenhouse (cough, cough, bullshit, cough) gases, whether burning petroleum or garbage, if combustion is complete, you produce the following major constituents:
CO2
H2O

Your minor constituents include
NOx
SO2
and whatever else makes up the fuel


But to give you an idea of the waste, let's compare my 2006 Jeep to a smug mobile electric car:

Looking at this should make al gore cry and cause instant death to polar bears.

Fuck al gore
