Dr. Sen Kim claims to have achieved the separation of Hydrogen using just 0.1kwh of energy compared to the traditional 4 - 4.5kwh required using the ol' electrolytic method.
The 2010 National Medal of Technology and Innovation to Rakesh Agrawal, Purdue University, for an extraordinary record of innovations in improving the energy efficiency and reducing the cost of gas liquifaction and separation.
This relatively minor shift, the model found, still produces enough energy to initiate a wave-like pulse of crystal-shattering snow separation that quickly propagates uphill and leads to a major release of the upper layer.
