~ Baterai Dari Kopi

Saat ini, teknologi terbaru Nespresso Capsules sebagai sumber energi alternatif. tengah dikembangkan agar dapat diproduksi secara massal dan murah. Nespresso Capsules ialah sebuah baterai hemat energi yang menggunakan kopi sebagai bahan dasarnya. Ide penemuan baterai ramah lingkungan ini pertama kali digagas oleh Mischer Traxler. Struktur sumber energi alternatif ini terdiri dari kapsul alumunium, dengan strip tembaga, air garam, dan tentunya bubuk kopi. Prinsip kerja baterai ini pun cukup sederhana, alumunium berfungsi sebagai anoda, kemudian tembaga sebagai katoda, sedangkan air garam berfungsi sebagai elektrolit. Bisa dikatakan proses kimia dalam baterai ini mirip dengan cara kerja baterai mobil. Dalam proses kimia yang cukup sederhana tersebut, setiap baterai mampu menghasilkan energi listrik sebesar 1,5 – 1,7 Volt. Baterai bertenaga kopi ini sudah diuji penggunaannya dalam Venice Design Week, di mana 700 baterai kopi ini mampu memberi tenaga bagi jam di festival teknologi tersebut. Saat ini, kinerja baterai ini tengah dalam pengembangan. Harapannya, kelak baterai ini juga bisa menggantikan sistem baterai yang lebih rumit seperti yang digunakan produk-produk teknologi informasi, diantaranya baterai laptop maupun baterai handphone.
