melanjutkan dari artikel sebelumnya......apaan sih sebenernya blue energy?
karena dari google indonesia kebanyakan isinya cuma artikel, jd saya ambil dari sumber bahasa Inggris aja biar cepet,haha (gampang kok bhs inggrisnya).......

Blue energy is a term for the method of generating electricity through the convergence of both fresh and salt water. The technology is based on reverse electrodialysis or osmosis where a fluid concentration which is higher than another will automatically pass through a semi permeable membrane in order to equalize all of the fluid.

Blue energy employs a large artificial semi-permeable membrane to create reverse electrodialysis from natural marine resources. The energy that results can be used to generate electricity. The only byproduct of blue energy is brackish water. Brackish water is simply a combination of fresh and salt water which naturally occurs in an estuary (suatu tempat dimana airnya perpaduan dari fresh and salt water).

Blue energy is only useful in certain geographical areas. The only way to create blue energy other than in a laboratory is at an estuary, where fresh water river currents and the saline tides of the ocean meet at the river’s mouth. Though the technology of blue energy has been understood for quite sometime, manufacturing the membranes was far too expensive to become a practical energy alternative. Recently, more economical membranes have been developed which will allow blue energy technology to begin being implemented in suitable environments. Currently blue energy is being used successfully in the Netherlands.

nah, dah ngerti kan....
tapi klo disini disebutnya blue energy dibuat untuk pembangkit listrik...
terus buat bikin artificial membrannya butuh banyak biaya...

nah lo,si Joko Suprapto itu emang kepinteran ato gimana, bisa bikin blue energy buat gantiin BBM.....yah mudah2an aja Blue Energy-nya si Joko ini berhasil.....kan enak tuh ngga usah beli mahal - mahal, tinggal ngambil di laut,haha....
