| + | ====== TEG ====== | ||
| + | The TEG, ThermoElectric Generator or Thermocouple Electric Generator, is my project to build a device to directly convert a temperature differential into a power source. | ||
| + | |||
| + | ====== TEG-MK1 ====== | ||
| + | |||
| + | The Mark 1 is a device that can be powered via a few candles, an alcohol stove (main intention), or a twig fire. The goal is to produce at 5 volts at a minimum of 0.5 Amps--the idea being this is enough to charge and/or power a usb device. | ||

| + | Note: I probably could and should just have a switch (DPDT) to switch between input and output voltages and amps. | ||
| + | ====== TEG-MK2 ====== | ||
| + | |||
| + | The Mark 2 ramps up power and size. It's intended to run off a large external heat source such as a gas stove or large wood fire. It's intention is to produce enough power (12v @ 4 Amps) to power and charge a Samsung 3 Chromebook. | ||
