Shop Class; Wednesday, Third Period [02/27].
"Welcome back, everyone," Amaya greeted the class with a grin that, by now, they should take to mean she was particularly excited about today's project. "For those of you who went on the trip to Iceland, I hope you had a good time. I know I did. Beautiful place, plenty of interesting stories and places, but what really caught my attention...and I hope a few of your attentions, as well...was the geothermal energy.
"Electricity!" Still a novel concept, shhh. "From the natural heat of the Earth and water! Providing power and energy to the majority of the whole country." Which was still pretty populous by her standards. "And so, today, inspired by Iceland, we'll be making our very own thermoelectric generator."
So...a bit of a step up from a potato, right?
"What we're essentially doing, then," Amaya explained, "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, which could be useful in the event of another power outtage like at the end of last year, or perhaps a few other small but useful devices in an emergency."
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 try 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, the 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!"
