Sаy yоu аre а scientist living in 1822, and yоu want tо find out which source of fuel has the most energy.  You want to compare coal and wood. Materials available to you: ---A forest ---A steam-powered water pump.  Basically, you can pump water with it using any type of fuel. ---A coal mine ---A river ---Other commonly available items such as cooking pots and potatoes (not necessarily useful to you). ---A group of hard-working laborers who have the skills and desire to do what you like.   Design an experiment using coal and wood, then evaluate how the results would influence industrial development in 1822. Predict how the choice of fuel might alter social, economic, and environmental outcomes in that era. Finally, propose how your experimental design could be adapted to test modern fuels like bioethanol or natural gas.
