Converting sunlight to electricity with solar cells has an efficiency of 15%. It's possible to achieve a higher efficiency (though currently at higher cost) by using concentrated sunlight as the hot reservoir of a heat engine. Each dish in the figure concentrates sunlight on one side of a heat engine, producing a hot-reservoir temperature of 510 degrees C. The cold reservoir, ambient air, is approximately 28 degrees C. The actual working efficiency of this device is 30%. What is the...

An inventor claims that she/he created a new device generating electricity. The device uses air as a working fluid. As a patent lawyer, you want to know the efficiency of the cycle. The cycle starts with heat transfer in at constant volume. The initial temperature is Ty and the temperature at the end of heat transfer is T2. Then, the air expands until the temperature reaches to T1. Heat transfer out occurs at a constant temperature. Plot this cycle on...

For example, for specimens incorporating air spaces or stud spaces, the metering area shall span an integral number of spaces (see 5.5). The depth of...
