Nanotechnology to Enhance Cold Fusion

Arata Solid State Fusion Device in Japanese Laboratory


(click illustrations above to enlarge)



[Updated] As a nuclear engineer with a strong interest in nanotechnology for many years, there aren't many cold fusion devices that I've seen and read about over the years that excite me as much as the potential of Dr. Yoshiaki Arata's solid state fusion reactor which uses Palladium nanoparticles to help initiate his cold fusion reaction process, which creates He4, the gas found in children's balloons from Deuterium gas (a readily available hydrogen isotope). What is also released in the process is heat energy from fusion. No small accomplishment as any physicist would tell you, because this process should be impossible according to the known laws of nuclear physics and chemistry.

What is also significant besides excess heat generated [ awaiting confirmation according to latest news update], is that if his process could somehow be scaled up in large volumes, perhaps ...just perhaps it may be a way to replace Helium supplies someday, which according to the latest reports is becoming a scarce non-renewable resource, often times released to the atmosphere as natural gas is collected along with fossil fuels. The US strategic Helium reserves are also known to be a finite supply, and despite this are now being sold off to meet supply needs of the scientific and commercial sectors.

If any cold fusion fans have read Dr. Arata's earlier important papers on this device, first published in 2006 in a very reputable Italian journal found here, then you would probably agree that an announcement like this is significant from the standpoint that it shows for the first time his actual prototype laboratory device and that he is now demonstrating it in public as also reported here in an interview by New Energy Times.

The Atomic Motor would like to send out an atomic guitar hero award to Dr. Arata and other fellow scientists who diligently keep trying and making significant progress against all odds in keeping the clean energy cold fusion spirit alive.

This latest story was first reported here at the LENR.org community web site:

Prof. Y. Arata Plans Demonstration at Osaka University

May 14, 2008
Osaka National University Prof. emeritus Yoshiaki Arata has announced a lecture and demonstration of his latest cold fusion reactor, on May 22, 2008, starting at 1:30 p.m. (subject to change). A photo of the reactor is shown below. The lecture will be on the 1st floor of Arata Hall on the university campus, and the demonstration will be later, on the 3rd floor. (Note that Arata Hall is named after Prof. Arata, who is one Japan's leading scientists, with honors including a building named after him at the university, and an award from the Japanese Emperor in 2006.)

Definisi Nanopartikel

0 komentar

Nanopartikel saat ini menjadi pembahasan yang sangat luar biasa oleh para ilmuwan. Karena sekarang ini dituntut segala prodak harus dalam bentuk yang sangat simpel dan praktis maka dari itu dibutuhkan alat yang sekecil mungkin tanpa mengurangi fungsi dan kegunaan dari alat tersebut. Maka dari itu para ilmuwan banyak mengembangkan risetnya tentang nanoteknologi. Nanoteknologi adalah ilmu dan rekayasa dalam penciptaan material, struktur fungsional, maupun yang lainya dalam skala nanometer. Dalam pengertian secara terminologi ilmiah , nano berarti 10-9 atau 0,000000001 jadi satu nano samadengan seper satu juta millimeter. 

Riset ini dimulai sejak tahun 2000, sampai sekarang ini sudah banyak menghasilkan penemuan – penemuan baru dalam berbagai bidang di setiap minggunya. Bidang – bidang itu diantaranya

  • Bidang elektronik : pengembangan piranti elektronik dalam ukuran nanometer
  • Bidang Energi : pembuatan sel surya yang lebih efisien dengan ukuran nanometer
  • Bidang kmia : pengembangan katalis yang lebih efisien
  • Bidang kedoteran : berkembangnya peralatan baru pendeteksi sel – sel kanker berdasarkan pada interaksi antar sel kanker dengan partikel nanometer
  • Bidang kesehatan : berkembangnya obat pintar yang dapat mencari sel – sel tumor dalam tubuh sehingga dapat langsung mematikan sel tersebut tanpa merusak sel yang normal
  • Bidang lingkungan : dapat menghancurkan polutan organic di air dan udara dengan sekala nanaometer

Sifat dan karakter dari partikel yang berukuran nano sangat berbeda karena sifat partikelatau material yang berukuran nano yang meliputi sifat fisis, kimiawi, maupun biologi berubah sangat dramatis. Sifat – sifat dari material tersebut sangat bergantung pada ukuran, bentuk, kemurnian permukaan, maupun topologi material. Setiap sifat material memiliki sekala panjang kritis atinya ketika dimensi material lebih kecil dari panjang kritis tersebut akan mempengaruhi sifat fisis fundamental material tersebut.
