Kapoore et al. observed an extraction time between 30 s to 20 min at a temperature of 120–140 °C. Solvents with strong microwave-absorbing capacity, such as methanol, ethanol, and water, can easily heat up, lowering the duration of microwave power application time, and should thus be employed in the processes.
The benefits of producing electricity from wind power that make the wind a perfect green energy source. Wind power is a technologically mature source of energy with enormous potential.
