More than 2/3 of the energy needed for today’s cars is just wasted, creating heat and polluting our environment – why do I never read about this?
Whenever there is a technology change, peoples arguments go crazy! Remember, when the first iPhones came out – the main argument against them has been „greasy fingerprints“ on the screen.
We seem to forget what the purpose of those things are. It’s like with our old light bulb: 95% heat (waste), 5% light.
From a light bulb I want light,
from a motor, I want speed, not heat!
Today I want to share just this small graphic I created, in relation to the discussion about the future of mobility. Of course there is a lot more to consider like getting the fuel/gas/batteries, weight, material, storage, life-time, recycling, lasting of resources… but sometimes pictures can add clarity (please let’s not discuss if it is 37% or 42% or 98% – we talk FACTOR 3 in efficiency – or in other words 2/3 of what combustion engines produce is waste, temperature and pollution, not moving us a single inch forward (which is the purpose of a motor).
Of course I have in mind, that there is a lot to improve with electric mobility – mainly battery and everything around that … but those things CAN be improved. It is highly unlikely that a combustion engine will ever have 90+% efficiency (and over the full course of RPM).
So let’s focus our creativity and energy on making the most efficient technology better and reducing their side effects.
