In educating engineers a broader background is required, including mechanical issues such as heat transfer and fatigue, which are now often neglected. In order to expand our role we should grow integrated projects at universities. In the process we will have to take aspects on board that we, classical electrical engineers, may not be comfortable with. A good example of such an issue is thermal management. New technologies and better designs of the thermal housekeeping may have more potential for increasing the power density than the conventional electrical approach of improving the efficiency.
