What are the advantages and uses of thermal energy?

Question

could someone also tell me whether its environmentally friendly, its for a project. i dont mean geothermal energy, just thermal energy.

thanx

Answer 1

Advantages of thermal energy:

- To create electricity by means of a power plant

-Help people stay warm when it's cold

-Evaporation of water to make steam (for heating, power generation, humidification, etc.)

-The removal of bacteria by sterilization (by heating something to a high enough temperature, you make the surrounding area unhabitable to bacteria and other microorganisms)

-Changing the viscosity (flow rate) of a liquid.  For example, in a steam boiler, if you wanted to burn a heavy fuel oil to make the steam, you would first have to heat up the oil to thin it out in order to increase it's flow rate through the piping)

-Soldering

-Welding

-Brazing

-Microwave Oven - using microwaves, or radio waves, with a frequency typically around 2500 Mhz (megahertz), you can heat up food.  As the microwaves are absorbed in the fats, sugars, and water in the food, they create thermal energy.

. . . i'll hit you back if i think of anything else.  Good luck on your project!  Any questions, send me an email at [e-mail].

Answer 2

Thermal energy has to come from a source. If you use gas burners you can use thermal energy to heat up an enclosure for anything. Baking melting etc.

If you want to use thermal energy from the sun you can use a few mirrors that is focussed onto a point and put a pot there to cook (actual device in Africa) Then you can use pipes on your roof to pump water through to heat up the pool or the geyser and then use electricity for the geyser at night.

You could also use a warm surface to turn a fan and use the rotation for something.

Answer 3

You should stop using it and learn to walk.

Answer 4

Environment is the surround where we live: All of living humans & animal ; inhale oxygen & exhale carban dioxide.

For the earth’s environment plant inhale carban dioxide  & exhale oxygen.

For Eco. Balance oxygen = carban dioxide

but by burning the energy resources to Generate the Power, release  the excess carban dioxide , which is causing the green house effect – due to this Global warming is taking place.

Energy resources are mainly – Conventional  & Non conventional

Conventional such as – Coal , Fossil fuel ( Diesel, Petrol, LPG,CNG, etc.) & Nuclear etc.

Non conventional -  Solar, Wind, Hydro & Bio diesel etc.

These are mainly for used generating power, using Thermal/Gas/ Nuclear Power Plants. Which is turn used for Domestic use, Industrial & Commercial purposes such as running Factories & Transportation, running Agricultural Infrastructures etc.  Obliviously with Industrial revolution energy requirement is tremendously increasing. However it leads to releasing of harmful gases and solid waste such as fly ash etc. which is causing Green house effect & Nuclear plant has risk of harmful radiations which is dangers to human life & animal kingdom.

Diesel, Petrol, ATF & Gas is being used in big way for IC& Jet engines which in turn used for transportation (LMV, LCV, HCV etc.) and Generators etc. Which in turn leading to Global warming, melting of polar ice & climate change etc.

We are still running plants based on old technologies, warn out & completed it’s full life may be 40 – 50 years old or more. In India we have seen the fiasco such as Enron Power, a new plant but due to red- tapism  couldn’t  be operated as per initial agreement & many more cases. ,  

Use of Freon in Air conditioners is also causing to damage to environment. By developing the alternative to Freon & curbing the use of it.

Where new alternatives are under Research & development such as Bio diesel using Zetropha seeds (Ratan Jot)etc. and Non conventional sources are still not economical compared to conventional ones except hydro in some cases.

As a social cause it’s the duty of all citizen, Govt. & Industry to conserve the energy recourse, by not exploiting them and Make our planet Greener & safer for all.

Answer 5

Well its good if u have coal mines near by .....but i think its not that environfriendly as compared to hyro electricity...
