Electric Wars and the Jundt Maxim
Updated: Oct 19, 2021
It has been noted that batteries possess an energy density two orders of magnitude less than hydrocarbon fuels. However, efficiency comparisons between these forms of energy warrants discussion. If electric energy can be more efficiently converted into mechanical energy the end use might someday justify an overwhelming conversion. The highest energy efficiency of an electric current 3 phase motor is 93% whereas internal combustion is around 35%.
If car batteries could be exchanged instead of recharged at stations, market entry would increase as longer distance treks could be performed with much shorter down time due to charging. Certainly, this has maintenance and consumer fidelity concerns in that poorly performing or inoperable batteries might be left at said stations. Also, advances in battery density will likely allow for ever increasing distances to be achieved.
The F35A produces approximately 43,000 lbs of thrust when the afterburners are engaged. Notably, in the VTOL (vertical take off and landing) configuration, the F35A engine will melt asphalt. One major problem with this incredible machine is the inability to exercise VTOL on aircraft carriers due to concerns over heat deforming metal substructures. That may be the worlds most powerful mobile blowtorch at 1700F and Mach 1 exhaust speeds. This represents one of the most technologically advanced in-service aircraft in the US arsenal.
Given this information involving one weapon in the US military, what is the maxim?
The maxim is that until conventional war fighting machines possess the energy density of hydrocarbons, we will remain dependent on the substances derived thereof. Certainly, if a dark energy or quantum weapon were developed, this maxim would cease to be valid.
