YEA but think about all the Salmon you will be killing.


Why? the two main salmon rivers are the Skeena and Fraser. They don't now, nor will they ever have dams on them.


BC gets about 90% of its power from hydroelectric-from the Columbia and Peace rivers. The BC power from the Columbia doesn't harm any salmon- because the dams downstream in the states take care of that... all joking aside, it's too bad we can't (or won't) develop hydroelectric technology that allows for fish passage. Hydro power is literally solar energy.
I have been to the Bonneville Dam in the Columbia Gorge. They have fish ladders for the fish to get around the dam.


They do but you really think they all get thru???? NOT hardly.

Why do you think the GREENIES that push Electric cars want the Dams removed? They claim the Dams KILL Salmon.

Yes, several of the dams on the lower Columbia have fish ladders, but there isn't one on the Grand Coulee dam that I know of.


That would be something to see if it was built.

^^^^ You may be right that the difference in mpg cruising down the highway might not be "that much". It would probably be 10% and overall mileage would be affected by about 15%. So in my case if I owned a smaller engine truck for 10 years I could expect to save $5500 .... I don't think it would pay for the electric axles I would want on my RV if I had the smaller engine.


Going from 5.0l to 6.7l in the same truck...I would be very surprised if there was a 10% improvement. I'm thinking more like 2-3%...maybe none.

Even empty both engines are far enough into their power bands that efficiency won't be greatly different.

I cant think of an application where two different displacement turbo diesels are offered in the same vehicle but the Honda Accord Sport is available with two different turbo gasoline engines of different displacement and I know the smaller engine is rated to get somewhere around 10 - 15% better fuel economy. It seems to me the Honda engines are both designed to make similar power per liter. In the example I'm talking about .... a 6.7 making 475 horse vs a 5.0 making 300 I would expect a greater spread in the low load fuel economy than in the Hondas case because the 5.0 liter can be designed with a higher compression ratio than the 6.7.

You see it a lot in boats and assuming you don't use those extra horseys, they difference is typically to small to measure.

Nissan's variable compression ratio engine does both. Low compression/high boost for power, high compression/low boost for economy.
