Researchers have developed a technology that uses sound as a means of converting heat into electrical energy. Converters based on this technology can be manufactured small enough to be integrated into consumer electronics, where they will absorb significant quantities of heat. A group of engineers is now designing converters to be sold to laptop computer manufacturers, who are expected to use the electrical output of the converters to conserve battery power in their computers.

Which of the following would, if true, provide the strongest evidence that the engineers' plan will be commercially successful for their group?


A) The sound that is used by the converters is generated by the converters themselves.

B) Most laptop computer manufacturers today receive fewer complaints than in previous years regarding shortness of operating time on a single battery charge.

C) The overheating of microprocessors in laptop computers presents a major technological challenge that manufacturers are prepared to meet at significant expense.

D) Although battery technology has improved significantly, the average capacity of laptop computer batteries has not.

E) Electrical power generated by the converters can be used to power the fans installed to cool computers' components.
