@Yidneck and other.
One thing I leaned early on in engineering classes is a simple fact and that is engineering its best is a compromise that weighs the pluses against the minuses against the true added value.
During my 41 year career in the lift truck industry I read tons of product literature and I quickly discovered that every body had heavy duty, this and that and long life characteristics but not one company stated they had a "light duty or short life piece of equipment.
A few years ago GM announce that the electric Volt car was going to be the car of the future and save the world - our fed government even help pay for each one that was sold. Recently GM announce the Volt will no longer be produced in it's current configuration - it will be a Hybrid. Telsa seems to be have some issues right now too.
Recall several years ago(like 20+) CNG fuel lift rucks was the way to go and everybody offered that option. last time I looked only Toyota offered that option. There were some significant issues not mentioned during the "hype" days - things like cost of refueling stations ( slow system cheaper, fast refuel systems big bucks plus they required some annual maintenance due to teh high pressures), refuel time and the fuel tanks had to be replaced within 7 or 10 years, fuel tank help less fuel and the tanks were thick walled and could only be refuel on the truck (no tank exchange possible) and trade in values of of CNG units dropped significantly as the second had market had little appetite for used units- units had to converted back to LP to be resold... Like I said before "engineering at its best is a compromise" - it was back in the 1960s and remain so today.
