The test circuit with power fuels made of Nickel and 10 % Lithium aluminum hydride filled with 20 grams in a nickel cell, made in the stainless steel reaction unit. The present heater is constructed of nichrome wire that is coiled on a ceramic tube. A consistent DC power supply is provided. Heater is shielded by magnesium oxide thermal insulation, filled in an aluminum hollow cylindrical jacket with internal dia of 55 mm and external dia of 25 cm and length 40 cm. Stainless steel protected K –type thermocouple is used to gauge the temperature. A thermocouple T1 is present on the outer layer of reaction unit, T2 is kept in connection with external surface of nickel cell and T3 is kept inside the container in link with the fuel powder. The test was conducted in the starting of May for four days.
On the very first day, vacuum was created in the reaction unit and then heated. The lithium aluminum hydride (LiAlH4) was degassed and higher pressure in the unit was maintained up to 400 kPA at the temperature range of 150 to 130 degree C. The pressure lowered to -90 kPA within 18 hours.
On 2nd day, temperature of thermocouple T3 rose to 950 degree C by power supply to 900W, the temperature of thermocouple in the fuel cell quickly increased. But T3 damaged at this moment. Although T2 was performing adequately and temperature of T2 was also increased to higher limit than T1 quickly. When temperature of T2 thermocouple reached above 1300oC for ten minutes, the power supply was stopped to secure the T2 from break. The self maintaining heat effect noticed and remained for twenty minutes and then temperature of T2 fell quickly. When temperature fell below to 1000oC, the power supply was provided again to 900 watts and an excited level of the abnormal heat production occurred since the T2 thermocouple was again at the higher temperature than T1.
The unknown kind of heat generation in (Nickel + LiAlH4) was noticed frequently. The production of heat was limited by the power supply and can remain for a long period. An estimated power of surplus heat is up to 600 KW and the ratio of surplus heat to power supply is 0.77. The use of nickel container and Nickel + Lithium aluminum hydride measured energy density is about four orders of quantity larger than the gasoline value. Hence the production of excess heat cannot be specified by a chemical energy.
