internal-combustion engine, any of a group of devices in which the reactants of combustion (oxidizer and fuel) and the products of combustion serve as the working fluids of the engine. Such an engine gains its energy from heat released during the combustion of the nonreacted working fluids, the oxidizer-fuel mixture.
This process occurs within the engine and is part of the thermodynamic cycle of the device. Useful work generated by an internal-combustion (IC) engine results from the hot gaseous products of combustion acting on moving surfaces of the engine, such as the face of a piston, a turbine blade, or a nozzle

One word; “freedom”.
Before ICE and hydrocarbon fuels: 90% of Americans lived on farms to feed the nation.
After ICE and hydrocarbon fuels: 2% of Americans live on farms to feed the nation.
Has any other industry seen such an explosion in productivity after the invention of internal combustion engines as agriculture?
LOTS of industries. But yes, the farming industry (and shift to industrial - also influenced hugely by fuel) is probably the biggest one in terms of social and economic impact in the USA.
Correct. Gas turbines use EXTERNAL combustion. That has not changed. The author goofed.
We could use External Combustion engines maybe ?
they are not so efficient but they can use anything as fuel.
As a side note I once read about a plastic surgeon in Beverly Hills who had an old mercedes diesel and he used the fat he got from liposuctions to power it.
Leftists hate internal combustion engines BECAUSE they enable great prosperity.
I am old. I remember back when my grandfather used a one horse drawn plow to turn his 40 acres and two horses to pull a hay wrak. All his crops were planted and harvested using horses. What happens when the new world order shuts down the mega farmers. No fuel, no electric. Just thinking it might be wise for small farmers to have a horse & plow.
I disagree. Heat is actually the enemy of ICE engines. That is why ICE engines need extensive cooling systems. The power comes from burning fuel which turns it into hot gases which have much bigger volume which creates high pressures inside cylinder of engine and that pressure causes pistons to move with force.
It is similar to steam engines. When water is converted to steam using heat, steam volume is much bigger than water which creates high pressure inside the boiler, and that high pressure steam then moves the pistons or turbines.
That’s arguable. According to Kawasaki: “Just like a diesel or gasoline engine, a gas turbine is a type of internal combustion engine and operates using the cycle of intake, compression, combustion (expansion) and exhaust. One major difference, however, is that the basic movement. A gas turbine is rotary movement, in contrast to the back-and-forth movement of a reciprocating engine.”

When I was a hatchling an external combustion engine was the steam engine, which were nearly all phased out when I was in grade school. I recall my dad bringing to our attention one of the last Great Northern steam locomotives still working in the mid-50’s. Steam engines for farming were completely replaced by gas IC tractors a little earlier.

I hear that liposuction fat makes good soap, too.
