Kompor Tenaga Surya
Kalau jawabannya belum, bilang sama orangtuamu untuk mengajakmu pergi ke museum listrik di Taman Mini Indonesia Indah, Jakarta.
Di museum itu terdapat sebuah kompor sebesar antena parabola. Kompor ini dibuat oleh Bapak Minto (Alm), beliau adalah seorang guru Sekolah Dasar Prambon I di Kecamatan Dagangan, Kabupaten Madiun, Jawa Timur.
Kompor besar ini mengandalkan pantulan sinar matahari (surya) melalui potongan cermin datar yang mampu menghasilkan panas tinggi. Selain itu, kompor ini juga bisa difungsikan sebagai antena parabola juga, lho! Hebat yah.
