Well it's not necessary to run your car on water because it already runs on
air. See the fuel is misted, mixed with air, compressed in the combustion
chamber, and hit with a spark. Now a lean fuel mixture runs hot while a rich
fuel mixture runs cool. So your air-cooled lawn mower is running a rich fuel
So just get rid of your yard grass to save fuel. One web source says that
Liriope grows only 1" tall and will make a yard. Then Blue Fescue is also
mentioned. Then they go to Clover...but hey I've seen Clover go to 4" high ?
Now there's an old joke about needing a car gas pedal that pushes back. And
so one car maker is making a gas pedal that pushes back. I suppose it looks
at speed and engine RPM and figures out if you are going up-hill or
down-hill...and then it allows less throttle on the down-hill.
But the driver can restrict the gas pedal on their own. Let the car gain
speed on the down-hill but use less gas pedal on the down-hill. Then on the
up-hill don't worry about losing speed but just try to make the hill crest
before the speed drops too far under the speed limit. When leaving a stop
light be the first to pull away (with ease) but then let the other cars
catch up and pass by...while looking ahead to the next stop light.
Now put air in your tires. If your car has the engine towards the front put
36 pounds of air in the front tires while if your car has the engine towards
the back then put 36 pounds of air in the back tires. Next with a full fuel
tank put air in the remaining tires to match the radial tire bulge of the
tires already aired. Fuel savings will be 7.5%...
Not much left that can be done...but a very large front spoiler or air dam
will save fuel. Consider a wave breaking on the beach and realize that an
air wave is breaking under your front bumper. Anything that reduces air flow
under the front bumper will reduce drag. And it's often said that a fully
skirted car has downforce but actually a production-based skirted vehicle
just reduces lift..but again drag is also reduced. And slide through the
And then the rear spoiler helps a little as it pitches rearward the airflow
that is coming over the car...
Oh save electric powerplant fuel and natural gas fuel. Just plant hardwood
trees around the house. They shade the house in summer but let the winter
sun pass through. Don't buy solar panels for the house unless you live in
the desert...because the trees will lighten the load on your
heating-and-air-conditioning system by an amount greater than the power
produced by a homeowner's quantity of solar panels. Now willow oaks are
popular because the leaves stay on the gournd after they fall and the acorns
are small. And a weeping cherry is not a thick foliage tree but the branches
are save to hang over the house. Of course Silver or Red Maples are good
choices but don't let the branches reach over the house. (Pull the seed out
of the Maple pod, boil it, and it tastes just like asparagus.) Then the
Bradford Pair is not so good because the tree gets so thick that the limbs
break off...even though the limb diameters are safe.
Back to cars. Buy a car with a four-valve per-cyclinder head. And that often
includes mechanical variable valve timing. Then lust for direct fuel
injection rather than port fuel injection. And look for 5 speed (and up)
automatic transmissions. (Now a manual transmission gets better highway
mileage than an automatic transmission but for the manual transmission to
get better city mileage requires an expert or perfect driver.) Finally look
up the weight of the car and consider the weight...
