The Physics Truth Behind the Quora Debate:
A gallon of gasoline contains exactly 33.7 kWh of thermal potential energy, but an internal combustion engine wastes nearly 80% as heat, traveling only 25 miles. The electric vehicle converts 85-90% of electricity directly into motion, traveling up to 160+ miles on that same 33.7 kWh. Conversely, escaping Earth's 9,400 m/s delta-v gravity well requires the rocket to lift its own massive fuel tanks; lifting an 80 kg human into orbit consumes over 1,600 kg of chemical rocket fuel. That is why electric cars transform daily life in 10 years, while orbital space travel remains an elite scientific endeavor.
