I participated in the GTTG competition in Bekasi City as a representative of Bani Saleh University. In this competition, I created a portable electricity generator using peltier modules. The generator works by converting heat from various sources, such as stoves, torches, campfires, and the sun, into electricity. This system operates similarly to solar panels, but instead of requiring light, our device requires heat to function efficiently.

Innovation distinguishes between a leader and a follower. - Steve Jobs

The device operates optimally at temperatures between 60-80 degrees Celsius. To generate 1W of power, we used 4 peltier modules and 1 fan for balance. The peltier works by exploiting the temperature difference between its two sides. One side generates cold, typically used in mini coolers, while the other side produces heat sufficient to make coffee. When the hot side receives additional external heat, it generates electricity.

Although we only placed in the top 5 in this competition, we managed to eliminate 80 groups in the GTTG contest. We consider this a significant achievement, especially since it was my first time participating in this competition. I am determined to continue striving for even better results in the future.
