Suppose a company wanted to develop an electricity-generating device based on the Earth as a blackbody. This company chose to base its operations in Death Valley, California, whose summers see a surface temperature of 35°C at night. What would be the work function of a metal that could produce photoelectrons from the peak wavelength of the Earth's blackbody radiation at this temperature? What would be the kinetic energy of a photoelectron produced by light half this wavelength?
