Why don't modern fossil fuel power plants operate at or near 100 percent efficiency?
That's because they convert the energy to heat first. Do some reading about the Carnot cycle, or the theoretical Carnot engine; briefly, if (for example) the environmental temperature is 300K (27 degrees Celsius), and the heat engine operates at 900K (627 degrees Celsius), then the maximum theoretical efficiency is (900 - 300) / 900, or about 67%. The efficiency achieved in real machines, of course, will be less than that.

What is the significance of the hovering power in the context of modern aircraft technology?
The hovering power in modern aircraft technology is significant because it allows aircraft to take off and land vertically, enabling them to operate in confined spaces and navigate more easily in urban environments. This capability enhances the versatility and efficiency of aircraft for various missions and applications.
What source of energy modern industrialized nations depend heavily on?
Modern industrialized nations depend heavily on fossil fuels such as oil, coal, and natural gas to meet their energy needs. These sources power manufacturing, transportation, and electricity generation, making them crucial for supporting economic growth and infrastructure.
Thermal efficiency of nuclear power plant?
The average thermal efficiency of a nuclear power plant, which accounts the heat produced in the reactor and the electricity produced in the turbo generator, is about 33-34%, varying on the type of the reactor as well as which fluid is used to cool the reactor and transfer the heat.
Does gas burn efficiently in modern vehicles?
Yes, gas burns efficiently in modern vehicles due to advancements in engine technology and fuel efficiency measures.
How does automatic refrigeration technology improve the efficiency of cooling systems in modern appliances?
Automatic refrigeration technology improves the efficiency of cooling systems in modern appliances by regulating the temperature more accurately and consistently. This helps reduce energy consumption and maintain optimal cooling performance.
Thermal efficiency in a coal fired power plant?
It can be up to 40 percent in modern plants, less in old ones
Why don't modern fossil fuel power plants opeate at or near 100 percent?
You lose energy to mechanical loss, heat escaping and electrical resistance.
How does the modern bicycle operate in the 1700s?
It didn't, as there weren't any "modern bicycles" in the 1700s.
Why does modern technology release more co2?
Modern technology needs more energy to work, which means more fossil fuels need to be burned. Fossil fuels release CO2. With more fossil fuels being burned because of a higher energy demand from modern technology, more CO2 is released.
What is the definition of industrial capitalism and how has it shaped modern economic systems?
Industrial capitalism is an economic system where private individuals or corporations own and operate businesses for profit, using industrial production methods. It has shaped modern economic systems by promoting competition, innovation, and efficiency, leading to economic growth and technological advancements.
What is the significance of the hovering power in the context of modern aircraft technology?
The hovering power in modern aircraft technology is significant because it allows aircraft to take off and land vertically, enabling them to operate in confined spaces and navigate more easily in urban environments. This capability enhances the versatility and efficiency of aircraft for various missions and applications.
What can Fossil Fuel and Natural Gas power?
Virtually anything. Fossil fuels generate electricity which can power most any modern devices.
