Naw - the correct response would be that everyone should have been riding bikes instead of cars. Then there would be no problem and lots of clean...
Thanks - I didn't know what the energy factor for electric water heaters was these days - so that makes your heat pump water heater 2-2.3x more...
Huh? Electric resistance heating is very close to 100% efficient. Only line losses come into play. If you're going to refer to the "up to" 30%...
Looks like the best heat storage water heaters have an energy factor of 0.7 and use about 220 therms/year or 18 therms/mo. The heat pump water...
I'm not sure where you get 30% - the DOE estimated it at 6.5% in 2007. Electricity FAQs - Energy Information Administration

If you get the 17" wheels/tires from the Prius IV - does that still count as stock? They should be a bit better than the 15" tires though the...
Good tires and an alignment should shave 5 seconds off easily. Do you have lap times for other stock vehicles? I'd guess that you'll find that...
The AGW "movement" started a long time before that... Global Warming Timeline
Sounds like the truck has some design issues if it doesn't auto-restart automatically and is lacking power. Why is he worried about slippery...
Yeah, I hate that. Especially when the kids are in the car we pretty much always drive with the windows up, A/C on and air on re-circ mode....
I wish that more diesel trucks were required to install particulate and NOx traps. The vast majority of diesel trucks (of all sizes) around...
I'm not aware of any other cars that use the same/similar front sway bar, so getting the touring bar is probably your best bet there. In the rear...
