2. A pair of venture capitalists appear on Dragons' Den with a prototype of an electrical generator they have developed that runs on dried compost. They claim that the generator can produce 5 MJ of electricity for every kg of compost that it consumes. Assume that the compost has an energy value of10 MJ/kg and a combustion temperature of 280°C and that the generator is designed to operate at room temperature (20°C). The inventors claim that the compost costs $0.50 per kg and they can get $0.50 perkWh of electricity produced. Determine if this proposal is cost effective and if it violates the second law of thermodynamics. What advice would you give the potential investors?
