Siemens, has just reported that the company has developed superconducting motors that can be used to run ships with electricity. No doubt, that electric powered vehicles are eco- friendly with good efficiency but now the question arises how many batteries these sea monsters will demand as compared to electric powered vehicles to power them up via electricity.
However, engineers are already using highly efficient superconducting electric motors to power large ships as a substitute to diesel but superconductors ability to operate at temperatures close to absolute zero, or about -273.15°C is still a big problem to make it happen. Now, Siemens has reported that they have overcome this barrier with the development of their new motor that uses high-temperature superconductors that work at -140°C.
In addition, by using these motors in large case under the ship that many cruise ships uses these days, the surrounding seawater will work as a very efficient cooling system to disperse adequate heat for the motor to enable it to function at required temperature.
Now, let us see how soon this new motor will help to overcome barrier that engineers are facing to power monstrous ships via electricity but we will definitely keep you posted.
