Heat energy production by quicklime and water
« on: June 13, 2014, 06:20:22 AM »
Dears,
All of us know that chemical reaction between calcium oxide (quicklime) with water will produce heat energy strongly by the following equation:
Cao + H2O = Ca(OH)2 -> releases heat energy

I have improved the reaction above to maximize the heat energy production with the following steps:
1.   I use a plastic jar whose volume is around 65.53 cm3. I put into the jar 3 full spoons of quicklime. (The volume of the spoon is around 7.85 cm3)
2.   Boil water
3.   Fill in the remaining volume of the jar with boiled water
4.   Then drop some floor cleaner liquid into the jar and shut it tightly
Result: After step 3, the mixture begins to bubble up and overflow severely. This results from the combination of 2 heat resources, one from the chemical reaction, and the other from the boiled water itself
Now we go to step 4. Here the additive to be used can be floor cleaner liquid as mentioned above, or dishwashing liquid, body wash etc..in general it is any foaming substance. By this, the seething mixture will be expanding more severely, and overflow the jar. Since the jar is shut tightly, the mixture itself and its heat are accumulated there, and results in the melting or breaking of the jar.
While step 3 upgrades the heat energy released by the chemical reaction to a very high level, step 4 itself is the turning point to force this energy breaking out most severely
Above is my way to create heat energy. The experts can consider it as a new method for energy solution. Just by a small jar with volume 65.35 cm3, I can create such significant amount of energy. If we use a larger amount, for example 1 kg of lime, the released amount of energy will be more terrible, in comparison with 1 kg of coal, or 1 m3 of petroleum, natural gas.

Cooking by the heat of the quicklime reaction has been known for centuries: http://www.oldandinteresting.com/fireless-cooking-with-quicklime.aspx  This is a little dangerous, however.  The production of quicklime is very energy intensive, so I doubt you're saving any money, particularly since you're pre-boiling water, and also adding a mass produced reactive chemical.  I just hope you're careful.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

No, Lime is very cheap here. And while the fuel sources in the world are exhausting, we can think of my experiment as a new solution, a new way to develop

Do you think that Lime is a renewable energy source?

Boiled water is not a heat source. Might as well skip that step.

4.   Then drop some floor cleaner liquid into the jar and shut it tightly

This seems bogus and a safety issue
