Hi there fellow gear heads,

I made the conscious decision to reduce my carbon footprint starting in 2006. Reduced my annual electric consumption from 5500kwh/year to 2200kwh/ year. Designed and built a 1.4Kw grid tied solar PV system with a total out of pocket cost of $3300. I like to do the mostest with the leastest.

Traded my 300K miles, 18mpg, 1986 Toyota 4x4, for a 45K miles, 29mpg, 2001 Tacoma. I acquired a 1989 CRX HF with 82,000 actual miles from the proverbial old lady in August 2008, because I needed to commute 650 miles a week, round trip that fall. My best fill up that fall was 620 miles on 8.2 gallons. I knew I was going to need a good mpg vehicle with the spike fuel prices back then. I read about Honda building 4 wheel independent suspension cars starting in 1988 and they had produced a car that could get 50 mpg. The hunt was on. I spent 6 months searching and found this on Craigslist and bought it sight unseen for $3000. I live in southwest Colorado, drove to southern California and towed it home.

I have pictures of a boattail that I built and removed because it really did not work as thought. Tried aero hub caps, a waste of time and money. Designed and built an awesome hydrogen system and got rid of it because it put too much load on the alternator.

I studied what the NASCAR and F1 guys were doing with computational fluid dynamics and designed my own nose additions to setup air flow at the front of the car and added a diffuser under the back. All I can say is that it works, it was simple and very in expensive. The best and easiest thing anyone can do to any car. No more squirliness in heavy cross and head winds. When the car hits 80 mph you can feel the car suck down to the road. I have pictures I will post. I have designed similar adjustments for a buddies 2001 Pontiac and improved his mileage from 37mpg to 44 mpg. Happy hypermilin' to you all.
