Kebebasan Energi

Ditulis oleh: Kurniawan

Pernah liat gambar yang seperti ini? Ini gambar hanya sebagian charger yang ada dirumah saya, mulai dari charger handphone, camera, Acces point dan sebagainya. Tanpa disadari semakin lama kok malah semakin banyak konsumsi energi dirumah kalo sudah begini seperti gurita saja, kabel dimana-mana. Mungkin anda juga tidak menyadarinya dulu satu orang mungkin hanya punya 1 handphone tetapi sekarang 2 bahkan 3 handphone digunakan sehari-hari untuk keperluan yang berbeda-beda. Itu baru handphone belum smartphone, notebook/netbook, tablet dan gadget lainnya padahal pemerintah sedang gencar-gencarnya program penghematan energi.

Mungin kalo kalimat kebebasan finansial kita sering dengar tapi kalo kalimat kebebasan energi?

Desain turbin angin

Teknologi wind turbine yang saya lihat di Indonesia sepertinya masih dalam bentuk biasa/standar saja. Sebuah wind turbine kalo kita dengar pertama kali langsung terbayang dikepala adalah baling-baling, ya itulah yang banyak saya lihat. Ternyata baling-baling itu banyak modifikasinya lho, dan banyak cara untuk "menangkap angin". Ini sebagian gambar dan video-nya.

Martin Aircraft’s commercial jetpack looks to take flight

It is about time man flew among the birds – alone. We may not have the homes on the moon, or the flying cars that our totally reasonable childhood imaginations ensured us would be waiting for us when we grew up, but with a little luck and a lot of money, we might soon be able to scratch “jetpack” off of our bucket lists.

Imagine one day soon, you kiss the spouse good bye, walk the kids off to the school bus, then you prepare for the commute to work. But rather than sitting in traffic and squeezing your steering wheel in frustration as the car in front of you apparently believes the old adage of “speed kills”, so they are driving 15 MPH under the speed limit, you simply throw on your jetpack, terrify a few birds, and make it to work in record time. Sure there might be a few details that you would need to work out, like the practicalities on your hygiene after ripping through the wind with an engine strapped to your back, or the fact that you are betting your life on the reliability of the vehicle, but we are talking about a jetpack- practicalities be damned!
