So much for a Nissan Leaf!

To my limited knowledge your calculations look good. Your assumption that all electricity comes from coal is rarely true. Most cars do not get 40 miles per gallon, buy certainly many hybrids do. I notice that another article use 28 mpg as a basis. I think you raised a good point though. I guess the best learning from this is that you have to know where your electricity comes from. My ideal approach would be improving the efficiency of internal combustion engines. I have seen two concepts that look very promising. One was a two pistons in each cylinder being pushed apart. VW was claiming 50% thermal efficiency from this. Another was a 6 cycle engine where water is injected in the I think 5th cycle. It turns to steam from wasted heat. You now get two power strokes for six cycles, versus one in four. I am glad there is so much development going on and so much interest. May the best ones win.

Just get out your gas generator and charge up your leaf. See how much gas you use and how far you go, put the A/C on and the headlights and the radio, and charge you phone too. You'll find your Leaf gets 2mpg. Lol.

A gasoline generator is a terribly inefficient system for many reasons. The engine is run at full speed all of the time. It is like running your car in low gear all the time. Also it is an air cooled engine. Large generators go to extremes to be efficient.

Makes more sense than shilling Coal powered cars that are labeled as "Emissions free".

Some folks value honesty, over politicaly correct lies.

We'll stomp those out as well...

You must know you are over the line when you throw this type of claim into the Thread. Please respect the wishes of the moderators and go elsewhere which your politics.

Saw a Mitsubishi Imev yesterday at a provincial park. Was impressive. I dont imagine there are many of them here. Lots of Leafs though. It even had a catchy "Powered by Wind Turbines" bumper sticker. Ironically we were only about 5 miles from the nearest turbine.

My kids were like "Daddy, its silent". Like they couldnt believe it. For some reason that made me smile, their world will be a lot better than ours, assuming we do the right things, like invest in green (all forms, from Nuke w/reprocessing to wind) and dont get mired down in that Nimby and other political crap.

So weather is political, why? Why is weather political to you. HS

:laughing::laughing::laughing: How many climate change threads have been moved to the politics area??? Your post was not about weather but about debunked nonsense. Please deny in the political thread.

I didn't assume all electricity comes from coal. In fact I never said that. I responded to a poster who claimed my earlier post was "so wrong", that even a coal plant was cleaner.

I'm glad you brought up the 40 mpg reference I used. I thought this one over, and I think it's actually the fairest comparison. 40MPG gas car technology vehicles are readily available today, and quite cheap.They represent the most equivocal comparison to a limited function battery car. It would certainly not be a very sound scientific comparison to compare a much more capable large gas vehicle like a pickup truck to the minimalistic battery car, as their capabilities are so vastly different.

The moth looked good, but its based on CO from coal plants, further percentages is needed reflecting where all US energy is generated. Gas/coal/hydro/wind/solar/nuclear, then balance the CO. Its would reflect a more accurate approach. I believe that is what Bob is referring too.
