It is important to have a general idea of how much energy can be stored and extracted from a certain form of storage. Record the specific energies of the listed storage types. Then make a chart (generated in Matlab, Excel, or similar) to display the relative specific energies.
Extra credit: Plot the specific energies vs. the cost/Joule of each storage type.

In this problem you will be using estimation to measure how much energy goes into heating water for showers in MA. Remember to state your assumptions clearly – you'll find that an estimate may be completely off because of just one assumption (but, conveniently, it's common that two bad assumptions can cancel each other out). Further, explicitly stating assumptions is key to the design process. We will start you off with the following assumption:
Assumption: Hot water for showering is about 105° F
