Ever been on a steam bath before? If you did, did you know
where it originated from and how it is made? Well the first steam baths where
used and designed by the ancient Greeks and Romans. They used pipes and pumps
that bring the hot water up to the pool areas, wherever the natural springs
exist (cited by http://en.wikipedia.org/wiki/Steambath).
Did you know that these natural hot springs are heated by the core of our very
own planet?

Geothermal Energy is heat generated from the Earth. It came
from hot shallow rocks and water and even in deep beneath the earth. It can be
used to generate electricity. So how do people utilize this and use it as a
form of alternative energy? According to www.nationalgeographic.com, there are
three types of geothermal power plants: Dry Steam, Flash and Binary.

Dry Steam is the oldest form of geothermal power plant. It pulls out steam from fractures in the ground and uses it to drive the turbine to produce electricity.

Flash Power Plants pull high pressured hot water into
cooler, low pressured water, the steam that is generated will be used to power
up the turbine.

Binary Power Plants the hot water is passed by a secondary
fluid. It causes the fluid to evaporate that drives the turbine.
Geothermal Energy has its advantages and disadvantages,
Geothermal Energy can be extracted without the use of any burning of fuel, and
especially no emission of smoke and it is available all the time. On the other
hand, its release of hydrogen sulfide, a gas that smells like rotten egg and
another is the disposal of a toxic fluid (cited from www
.nationalgeographic.com).

Uhuh. Thumbs up for a substantial blog! :) :D
ReplyDeleteI understood about the Geothermal Energy part. The explanation is a bit short so it sort of limits what my mind can perceive. It would be more helpful to the reader if the explanation is more brief.
ReplyDeleteIt's a nice, organized post although it skimps a little on the info. A good post nonetheless.
ReplyDeleteeverything is well said,it seems that the explanation are short, however..it was easier to understand with the images..
ReplyDeleteVery concise and very informative! However you might need to expound more on some points as for everyone to fully understand. But putting it in layman's terms? AWESOME. :)
ReplyDeletenice article. it gives us an idea on what is geothermal energy all about.
