Nice run today. Not too cold.

What does the concept car Chevy Volt and Bike Speed have in common?

Aerodynamic performace TRUMPS weight...they just figured this out via wind tunnel testing for their new electric car.

See Full Article  (I have been following the development of this car for some time)

"You will remember how Bob Lutz previously told us that the concept Volt did not do so well in the wind tunnel. We also heard from vehicle line director Tony Posawatz that it turns out aerodynamics is more important than mass or electricals for getting the Volt to make it 40 miles on a charge.

Frank Weber, E-Flex vehicle line executive states:

“The electric range of the Chevrolet Volt is most sensitive to improvements in aero, which is in contrast to a traditional vehicle program in which mass typically plays a larger role.”

GM now tells us through aggressive work in their state of the art wind tunnel, and through the efforts of a team of designers headed by Bob Boniface, they have made significant progress getting the Volt more aerodynamic; hence the new design above.
Aerodynamics apparently accounts for about 20% of any vehicle’s efficiency.

Ed Welburn, GM VP Global Design states:

“I’m proud to say that after extensive aero development of the Volt, and more to come, we have achieved a vehicle that had a coefficient of drag that is more 30% lower in drag than the original concept,”…“It’s not easy, but it is a necessity.”

Rainy all day.  Considering the workout in the woods yesterday, best to relax.

Thought: would singling out a 'Strength' forum make the issue worse???  Would this backfire on the stated intent?

Pulling trees off of a hill, sectioning them and splitting them into firewood.  Great workout.

This was just the swim I needed to get some drive back.

Indoor track. BOOOORING. I decided to make up my missed run and also see if my ring was in lost and found...halfway there my wife calls saying our son found it. Though I wish I didnt accidentally break the downstairs sink in taking off the very old and, corroded, trap.

It's been a bad day.  Figured out my wedding ring is not on my finger...I may have lost it in the pool yesterday.  I missed my run as I have been running behind on a ton of stuff.

2008 is going to have to change.
