Begitulah judul yang tertulis pada Twitter @TKE_Americas (ThyssenKruppElevator). Setelah dilihat link nya ternyata lift tersebut merupakan sebuah konsep dari pelajar di Banyumas.
Berikut “cuplikannya”
Banyumas (ANTARA News) – Three junior high school students of SMP 2 Banyumas, Central Java, have created an energy-efficient elevator that uses water as a counterweight.
When the reporter met them, the three students, who had joined the Youth Scientific group at their school, said the elevator was named “Lidirum,” which was a combination of their names: Yuli Setyani (15), Dimas Satriawan Risen (14), and Rumiati (14).
“The idea of making the elevator came from thinking about the traffic congestion in Jakarta, while the existing pedestrian bridge is rarely used by residents because they have to climb the stairs,” said Yuli Setyani.
Seeing this, she and her friends tried to find a solution to make the existing pedestrian bridge more comfortable, so the citizens would want to use it.
“With the guidance of our physics teacher, Aji Sambudi, we ended up making a miniature elevator for the pedestrian bridge and got the second prize for the Scientific Creativity Contest Youth (LPIR) National Level in Banjarmasin, Kalimantan,” she remarked.
Regarding the elevator’s mechanism, Dimas noted that the elevator works by using a pump to supply water to the tank acting as a counterweight.
“When the counterweight tank fills with water, the elevator rises to the top, and if the water in the tank is released, the elevator will go down,” he stated.
