No one pays you too much mind when you roll your shopping cart through the local hardware store, grabbing up plywood and screws, hinges and nails. A happy salesmen offers you a quick discount on steel and glass wool, which you greedily snatch up in bulk quantities. It all goes on your Chris Titan Credit Union credit card at the register; you're sure that you'll quickly make enough money to pay it off once you start selling these things.

Back in the garage, you clear a space on the old wooden workbench, shoving all the broken toys and failed projects aside to make room. After scanning quickly over the simple plans you found on that pretty reliable website, you immediately set to work, continuing long into the night and through to morning.
As the sun rises, you look upon your first set of accumulators, all ready to charge up.
