Shop Class; Thursday, Second Period [03/04].
"Morning, everyone," Amaya grinned a little as she nodded, greeting the class. "By this point, I'm sure you're probably well acclimated back into the swing of things after the trip, and today, I thought we'd do a project that was originally inspired by a trip a few semesters back, one that involves something that you're all probably a bit more familiar with than I was when I first got here, and that thing is electricity! Now, there's also been a few times where incliment weather or invading attacks have rendered this place without power, which isn't a problem for some, but others might be used to the conveniences that electricty provides. So it's a good thing to know how to make something like thermoelectric generators! All you'll need is just a few parts, a tub of water, and some candles.
"What we're essentially doing, then," Amaya continued with her explainion, "is creating energy based on the temperature difference between the heat from candle flame and the cool water in the small tubs we'll be using. This should be powerful enough to charge a phone or perhaps a few other small but useful devices in an emergency. And I'm sure some of you," *cough*Shuri*cough*, "could easily modify this to create more power to help energize something with a bit more oomph, too."
So the students would find a handout of instructions on their workstations as well as the materials they needed, as Amaya led them through the steps: starting with a handful of thermoelectric plates, which would generate electricity as it heated up one side while cooling down the other, and sticking them to the bottom of a container for the cold water. They'd be using bread tins, because they really did work pretty well, using thermoconductive glue and then saudering the black and red wires that stick out from the plates together, closing the circuit, and protecting the wires from creating a short circuit against the metal pan with some electrical tape. Then on to hooking up a voltage regulator to stabilize the energy passing through the plates, which would also serve as the plug-in point for their devices. They'd be mounting it over the tin with a strip of aluminium to keep it out of the water. Place the strip, hook up the wires to the regulator, another bit of aluminium over the plates, and onto the stand! With more aluminium!
And now to test it out! Line up the candles underneath, pour some cold water into the tin, let the thing get juiced up, and give it a try!
"Now, as the water warms up, it'll need to be refreshed, because the difference in temperature is key to what creates the power," Amaya offered as she finished up the demonstration. "Using snow or ice is actually more effective because of this...so next blizzard that sweeps in and knocks out the power, the lot of you should be all set! And if you make a big enough one, I'll bet it would be pretty snowman proof, too!"
BECAUSE THAT WAS A THING.
"So, let me know if there's any questions, and, if not, let's get to work!"
