Are we heading the right direction in dealing with worldwide energy demand ?. In attempting to engineer our way out of our energy problems, have we overlook the obvious, and instead embarked on a course of building the ultimate Rube Goldberg machine.
Using my own vehicle (2006 Dodge ram pickup) as an automotive example. The vehicles actual operating fuel economy varies from 10 miles to the gallon to 21 miles a gallon depending on driving conditions, with the average around town fuel economy being about 11 1/2 miles per gallon. In an ad hoc experiment timing the traffic lights on an early Sunday morning I can easily exceed 15 mpg. (Using the onboard milage display, not necessarily perfectly accurate but consistent for purposes of comparison).
I could install some sort of energy recovery device whether that be flywheels, electric motors hydraulic actuators and convert it to a highbred, however the same thing could be accomplished without all the complexity if cities would simply synchronize their traffic lights whenever possible, simple conservation of momentum. In this way all vehicles would realize sizable increase in fuel economy, without being a highbred.
Keep it simple stupid.
Many energy conserving strategies require no more engineering than the stroke of a pen. Four day work weeks, work from home are at the top of the list but there are others.
Something as simple as a change of insurance laws, and possibly flexible vehicle registration fees.
Here in California where I live every vehicle must carry liability insurance, the operative word here is vehicle.
With one somewhat embarrassing exception my avatar generally does not go anyplace without a driver (since then I've repaired the parking brake latch), however I must carry separate liability insurance on every vehicle I have.
Insurance and registration fees are a large capital outlay for something that you don't use daily. I personally have a motorcycle as my fuel efficient toy, however there are others that aren't as fortunate that require a large truck for their employment and cannot afford the cost of ownership of a second more fuel-efficient vehicle to use when the truck isn't required.
As far as liability insurance ensuring the driver instead of the vehicle would seem to remove at least one barrier to owning a economical part-time driver, and certainly legislative incentives and reduced registration fees could encourage those who either want or need a large vehicle into buying a puddle jumper for used whenever possible. In other words increasing fuel costs and decreased ownership cost could make it economically attractive to own a spare greener vehicle.
Hopefully without preaching too much to the choir most reading this form know that engineering anything is a compromise. If aircraft were engineered with too many redundant systems and packed with every safety device you could think of ,you would end up with something too expensive to build, or a very expensive bus as it would too heavy to get off the ground. Would it be better to apply engineering compromises to energy policies?
Offshore oil drilling, synthetic fuel production, modifying or easing of emission standards could all reduce dependence on a very volatile oil market.
Many countries have large coal and oil shale deposits that could be used in creating synthetic fuel. Synthetic fuel could not only supply gasoline, but also methanol, or hydrogen, which in turn would make hydrogen fuel cells and hydrogen powered vehicles much more practical than attempting to obtain hydrogen strictly through electrolysis.
(Hate to mention hydrogen it brings out the guys with the tinfoil hats, and the run your car on water ads)

PS. Through in the one about the lightbulb just to show how to turn disposing of a lightbulb into a Rube Goldberg scenario.
PS PS I'll ask your forgiveness in advance for any editing or spelling errors that I've missed. Already noticed I forgot to put commas in the Pathfinder tags.
