Empat gadis remaja Afrika telah mengkagumkan pelawat karnival 'Maker Faire Afrika' dengan hasil rekacipta mereka, sebuah mesin penjana tenaga yang dikuasakan dengan kencing. Menggunakan sumber yang sedia ada dan mudah diperbaharui iaitu air kencing, mesin ini menghasilkan tenaga elektrik yang mampu bertahan sehingga enam jam lamanya dengan hanya seliter air kencing .

karnival 'Maker Faire Afrika'
Maker Faire Africa ini merupakan satu organisasi yang telah di perkenalkan oleh Mark Grimes yang merupakan founder Ned.com bersama-sama dengan Emeka Okafor (TED Africa),Lars Hassleblad Torress (IDEAS Global Challenge), Erik Hersman (Afrigadget)dan Nii Simmonds (Nubian Cheetah).Maker Faire Africa di adakan bagi memberi peluang kepada individu.mahupun organisasi di Negara Afrika bagi menghasilkan inovasi terbaru bagi memudahkan kehidupan seharian khsususnya bagi kegunaan penduduk di Benua Afrika sendiri

Future science stars? Three of the girls who invented the pee-powered generator.

n a stroke of ingenuity that could have proven handy during Hurricane Sandy, four teenage African girls have come up with a urine-powered generator.

Duro-Aina Adebola, Akindele Abiola, and Faleke Oluwatoyin, all 14, and Bello Eniola, 15, collaborated on the invention, which they claim generates one hour of electricity from one liter (about a quart) of urine.

ade ape dlm air kencing smpileh jana tenaga?
kandungan urine pun dh almost 99%, takkan urine kot?

the key words is "urea"....dari situ urea akan di tukarkn kpd ammonia,..kalau cik dausq baca link yg diberi dlm post kiter,...cik dausq akan mngetahui bhawa hasil kajian dan inovasi "pee pawer" telah lama di selidiki oleh ramei saintis,
cth batteri urine dari saintis singapore
.. termasok la NASA dalam hal ini...penguraian dan penghasilan hidrogen dari "pee" still requires an outside sos of elektrik.

Menggunakan sumber yang sedia ada dan mudah diperbaharui iaitu air kencing, mesin ini menghasilkan tenaga elektrik yang mampu bertahan sehingga enam jam lamanya dengan hanya seliter air kencing .

Idea yang bagus... tapi macam ada 'terlebih' quote...?

Duro-Aina Adebola, Akindele Abiola, and Faleke Oluwatoyin, all 14, and Bello Eniola, 15, collaborated on the invention, which they claim generates one hour of electricity from one liter (about a quart) of urine.

Berapa 'power' electricity generated juga sebenarnya perlu disebut? Bila tak disebut, kita jangka arusnya SANGAT KECIL. Kalau arus besar, memang banyak company yang akan develop generator guna air kencing. CONFIRM! Boleh buat duit, kalau electricity generated tu besar!  

Satu lagi, ia melibatkan electrolysis, yang perlukan tenaga. (TAPI tujuan nak hasilkan tenaga).

    Urine is put into an electrolytic cell, which separates out the hydrogen.
    The gas cylinder pushes hydrogen into a cylinder of liquid borax, which is used to remove the moisture from the hydrogen gas.
    This purified hydrogen gas is pushed into the generator.

Hydrogen, of course, carries explosive risks, so the girls used one-way valves as a security measure (whether that is safety precaution enough is unclear). But don't start saving your bladder output just yet. The blog doesn't mention where the energy needed to power the electrolytic cell comes from, or whether the electrolytic cell uses more power than the machine generates.

The claim is huge, but the data is NONE. The concept & idea is good, but the setup looklike NONSENSE. For researcher like me, I would like to see the data to come to conclusion whether the claim is valid or not. But looking at the setup, I would rather say it is just a GIMMICK for such claim
