"Unless and until battery technology is developed that allows quick charging times and longer range, electric vehicles will remain as they are: playthings for the rich and something for the greenies to praise."
Bingo, again.
Since the late 1970s, I have advocated super capacitors, rather than batteries, for electrical vehicle (not necessarily heavy trucks, but why not) energy storage.
Of course, additional development of super capacitors is obvious, but consider the concept of stopping at your local Duke charging station for a 10-20 second 50K+ Amp recharge while you buy coffee, soda and snacks and sign your CC form before moving on.
Of course the recharge station would be connected to a HV line and have much larger super capacitor banks for the temporary storage of energy rather than underground fuel tanks. Such stations would receive power from efficient generating plants operating at optimum efficiency from coal or nuclear prime energy sources. Again, of course, NG plants could be implemented, as is the situation today, to supplement the primary generating plants during peak periods.
Dean, who is a retired patent attorney and wonders why no one is pursuing this.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
