Indian Neutrino Observatory (INO) to boast world's biggest magnet

INO is setting up a neutrino observatory  in Bodi West Hills Reserved Forest in the state of Tamil Nadu. This is the first of its kind in India. INO plans to study atmospheric neutrinos. The Hills selected for this observatory is a granite block which will help in shielding the muons. This observatory will have the largest magnet 50,000 tonne magnetized iron compared to 12500 tonne in CMS detector at CERN's LHC. INO is hoping that the observatory will also detect anti neutrinos as well.

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.
