An interesting question about the branches of civilization
What would happen if oil wasn't found on Earth?
Let's move on to the steam and electricity branch route for hypothesis. Pen ~ fun ~ pavilion www.biquge.info
Regardless of civilization, vehicles are the first priority to consider.
In the choice of steam propulsion mode, in fact, there is not much room for choice, regardless of the increase in steam pressure and temperature, it must rely on the external air pressure to balance.
But the biggest feature of steam is that the output is smooth, including the start and the highest output, it shows that it is very smooth.
To use the simplest example, the most advanced steam turbine start-up also takes more than ten minutes to improve, if you want to talk about the steam explosiveness, it is only the boiler explosion to say the matter, but that is a matter of atmospheric pressure.
Therefore, after a certain development, it will be transferred to the power branch, and the stable output of steam can provide good electricity, and the largest power mechanism in the field of power is nothing more than electromagnetic force.
With very little electricity, it generates an unimaginable magnetic force, but it has a very small range of action, with the optimal output size range of only a few millimeters.
What's the use of this?
To reverse the extrapolation, such as a conventional engine, then you need to build a linkage mechanism several meters long to get the power of a traditional combustion engine.
This makes no sense, the force of the explosion and the force acting close to microscopic size are two extremes.
So, one might look to the realm that is closest to this power.
Muscles, yes, are something that everyone has, and they form an alternative engine with minimal scale and weak electrical impulses, fueled by ATP.
So what is the world like when steam is developed and electricity is rising?
There is no doubt that the stable steam engine, the precise mechanical structure, the unimaginable 'engine oil', and the electrical energy structure under the microscopic size have created a terrible alternative power mechanism.
Speculating on the processing capacity of humans, the biggest possibility is that the complex hydraulic propulsion structure and the ingenious upgrade induction control system will still enter the automation of humans.
But this time, it's not about tires, tracks, and propellers, it's about air pressure control and bionic structures.
Looking back, if you want to build a humanized machine, you can only do it without any problems as long as you kill the oil system, because the explosive power of fuel is higher than the instantaneous output peak of electricity.
Of course, there is an alternative solution to this problem, oversized and overweight machinery, electricity is much better than fuel, at least you don't have to think about whether to use explosives as power to create the legendary super-explosive power machine.
