how we can use heat as a source of energy,?

Question

heat is also a form of energy , if we can absorb heat and convert it any form of energy it will be a solution of energy and oil crisis

Answer 1

That's how power plants work...they heat water to turn turbines..to turn generators.

You can use nuclear energy or coal or oil to heat the water.

In iceland they are lucky because they have lots of geothermal heat from volcanoes so the earth does the water heating for them.

Maybe we could drill to the core of the earth and use that!

Answer 2

Any activity releases waste heat. When a car moves along the road, the friction builds up waste heat, melting the tires. When the car stops it builds up waste heat at the break pads through friction, etc. It is part of the very shape of the universe to loose useful energy through entropy (see “laws of thermodynamics”) The goal for any new energy source is to produce more energy than it implicitly looses as waste energy. One very successful example on the market is the hybrid cars that use the energy of stopping the car to turn turbines and charge batteries to add a boost in getting the car rolling again. But that law of thermodynamics will bare out when you test the tire system efficiency: you’ll never get 100% recovery of waste heat energy to useful energy.

Answer 3

The most common way is to use the heat source to boil water. The resulting steam can drive a reciprocating steam engine or a rotating steam turbine, which produces mechanical power. If you want electric power, use the output of the steam engine or turbine to spin an electric generator.

You ALWAYS need a difference in temperature to extract useful mechanical or other energy from heat energy. This is why power plants need so-called 'heat sinks' in the form of bodies of cold water (rivers, lakes or seawater) or 'cooling towers' which dump the low-temperature waste heat into the air. Just as you cannot extract hydroelectric power from still waters (you need to let the water fall through a height to drive a turbine), so you cannot extract useful power from heat without letting the heat flow from a high temperature source to a low temperature sink.

Answer 4

We use heat all the time as a source of energy. It's actually COOL that we're missing...we have all kinds of ways to create heat...not too many ways to cool things off...

:)

Like the cartoon says...

Think about that.

Answer 5

First, young people like yourself must attend college in mass and work on their critical thinking skills. Then, I suggest a major such as mechanical engineering with a strong emphasis in thermodynamics. Remember, junior college will not feed the bulldog here. Hopefully, then with the grace of god will your generation will come up with a truly viable alternative to oil.

Answer 6

well there is pyrokinesis, if you can believe in it its possible, I can do telekinesis but, I cant do pyrokinesis, havent tried much, I can absorb energy from any object you can think of... but yeh if your into it try pyrokinesis it might take you 6 months to learn but it would be worth it... but its not about absorbing heat, you just become one with the flame, and direct it to move...

Answer 7

Bismuth Telluride converts heat into energy (but of course it is expensive so far)!

Answer 8

True but where are you going to get the heat from?Using the Sun is a good idea,but to many solar panels are needed,and are to expensive.The average person cannot afford it.

Answer 9

You could also try to create electricity using a thermocouple.

Answer 10

yeah it would be a good way. just tobad its not used all over the place
