The Tickler — More than a Brain Teaser
RJ Mical has been delighting his group of subscribers with a MONDAY TICKLER for years. When you put your email on his list, you will get a weekly puzzle that you may … or may not… be able to solve. It’s fun, gets me thinking but this time he and his group has delved into the Efficiency / Electric / Hybrid Car puzzle. See below for their answers, all smart and thoughtful. If you want to sign up for a weekly Tickler, just email RJ at:<rj@mical.org> and you’ll be part of the fun!
From RJ: I asked questions about getting fuel efficiency with my electric
hybrid. Should I use up the EV mode in the city or on the highway,
etc. The results were awesome! I got some pointers for additional
research too, and I think car makers should tell us a lot more about
what they know. I’m going to publish the info I’ve collected on the
website, but meanwhile here is a compilation for you.
=== RESULTS ===
Marvin came up with an excellent suggestion! “Wouldn’t it be great
if the car figured it out by itself, using temperatures, types of
road, wanted arrival time, prices of gas, etc…”
Lots of people, such as Jeroen, Daryl, Frank, George, and Scott, got
all scientifical with a ream of information regarding the engine and
temperature. As they describe it, the factors are so complex and
interdependent that it seems Marvin’s solution – have the car do it
for us – may be the most sensible one. “There is no real scientific
math to this. It would require so many factors like temperature,
wind direction and speed, average driving speed, hills, corners,
braking and accelerating. That is why your car always ‘guesses’ the
mpg. Real facts. Temperature is one of the biggest, if colder you
use up more, first of all because you got your heating on. Second,
as it really gets cold, say 14F and while you’re driving, it drops
even further to 5F, your engine just won’t get to its temperature,
the coolant through the radiator gets cold and the engine loses its
heat.” Jeroen provided a website (ask me for the link) that could
make one rethink hybrids altogether. “Of course, this all varies
with temperature. Batteries do not work as well when they are
chilled. And they’re not really very happy if the temperature is
110 in the shade and you push them hard.” Especially not if that’s
110 centigrade.
Jerry made a superb point, caught me off-guard! “If you burn gas on
the first part of the trip, you’ll shed a noticeable amount of
weight, making the rest of the trip more efficient. For that reason
you should prefer hybrid mode for the first part of the trip as long
as you use up the EV capacity by the end of the trip.” Well done,
Jerry!
Paul: “Get a Tesla.”
Charles: “Take that WhamJoy out on the road and give it a spin!”
Stan: “Don’t start hyper-miling on us.”
My favorite: Mathilde brought up the most thoughtful point of all,
that by using the EV mode in the city, for city driving, we help to
improve “quality of air” where congestion is worst and human
exposure is highest. “I guess ethics is a way to ruin your
mathematical approach to this problem,” said charming Mathilde.

It’s fun it’s inspiring, if you have an opinion (YES YOU DO!) then comment. It has just started for all our SF Bay livers and lovers, do take a look, this post really made me smile: 
WordPress is blogging software, and if you have to speak up…. I recommend this tool. It is easy, elegant and well-supported.
I am a great dog-walker. If you need someone and you live in San Carlos, Belmont, Woodside, Redwood City, Palo Alto or Menlo Park, let me know. I have years of experience and have cared for a variety of animals.
I think the best gift of all this year is … getting together with friends. Rather than gift things, how about an occasion. A group of us met for Holiday Cheer – Pizza, Wine and a movie shown at home. It was wonderful to discuss recipes, places to go, holiday plans, kids, and catch up. It was a great celebration! This is my number 1 choice. Here are a few more:
