Thermoelectric power generations from vehicle exhaust gas by using TiO₂ nanofluid cooling / Mohd Noor Hariz Mohd Hilmin

Vehicle engine efficiency is a big challenge today since it is considered low by approximately around 30% only. More than half of the energy is loss in exhaust piping and heat dissipated through cooling systems. There is an urgent need to tackle these issues in order to reduce the world energy consu...
