Purdue chemist Linda Wang and her colleagues heated water to between 716 and 932 degrees Fahrenheit at pressures approximately 2300 times greater than the atmospheric pressure at sea level. When purified polypropylene waste was added to the supercritical water, it was converted into oil within in a few hours, depending on the temperature. At around 850 degrees Fahrenheit, the conversion time was lowered to under an hour.
From the above - so how much energy is needed - to get this working - and how long does it take ..... does not sound feasibly useful - but we will see how far it goes ........ one day they may realize all the easy fuel has gone from under the ground.
