Choosing useful Firefox plug-in is a big challenge. Dhiraj in his neobinaries blog talks about the five useful Firefox plug-ins, I find ScrapBook very useful.

Perpetual machine

As a child, my idea of perpetual machine is connecting the shafts of an electric generator and electric motor, which are also connected electrically to make complete loop for flow of energy, but it took me some time to realize that things are not perfect. In my 10th grade I learnt about eddy currents which made my perpetual machine no more perpetual with time I learnt that they are many other factors which make my setup lesser and lesser perpetual... Bhaskara II in 12th century introduced this concept after this many mathematicians and physicists came up with many designs but with no success. Even though some of these designs (like drinking bird, Crookes radiometer etc) may appears to be perpetual but they are not truly perpetual they consume some sort of natural energy like temperature gradients, phase changes of water or other fluids etc. Recently a company named Steorn claimed to have built a perpetual machine but their public demo was a failure.

Low Temperature Thermal Desalination

14 years back I read an article about sea water desalination plant which works on the temperature difference that exists between deep and shallow waters, but I wondered why no one is putting these ideas to practice in spite of drinking water problems in many parts of the world. Recently while digging for information related to Setu Samudram project I happened to read about NIOT’s desalination project (Low Temperature Thermal Desalination) in kavaratti based on the temperature gradient of the sea waters. LTTD works something like this the warm ocean waters from the surface are evaporated in low pressure containers and the cold waters from the deep oceans are used to cool the vapours. With a heat engine electricity can also be generated from the water vapours. I feel this technology is better alternative to silicon based solar harnessing technologies which requires huge surface areas for solar panels.

I am rare

I found this link in one of the blogs and took a dig at it. Here's what I found. See, I am rare!!
Your Personality is Very Rare (INTP)
