The present invention provides a solid-phase catalyst for decomposing hydrogen peroxide comprising a permanganate salt and a manganese (II) salt. The solid-phase catalyst stays a solid state in the form of nanoparticles at the time of hydrogen peroxide decomposition, and thus can be recovered for reuse and also has an excellent decomposition rate. In the method for producing a solid-phase catalyst for decomposing hydrogen peroxide according to the present invention, a solid-phase catalyst is produced from a solution containing a permanganate salt, a manganese (II) salt, and an organic acid, so that the produced solid-phase catalyst is precipitated as a solid component even after a catalytic reaction, and thus is reusable and environmentally friendly, and cost reduction can be achieved through the simplification of a catalyst production technique.

A supply system for providing at least oxygen depleted air and water in a vehicle includes a catalytic converter, at least one hydrogen supply means, at least one air supply means, at least one outlet for oxygen depleted air, and a control unit coupled with the catalytic converter. The catalytic converter is couplable with the hydrogen supply means and is adapted for producing water under consumption of hydrogen from the at least one hydrogen supply means and oxygen. The catalytic converter is further couplable with the at least one air supply means for additionally producing oxygen depleted air. Further, the control unit is adapted for selectively operating the catalytic converter based on a demand of water and oxygen depleted air.

A method for providing purified, re-mineralized water (127) in magnesium and calcium ions comprises the steps of providing a flow of feedwater (101) and purifying and/or demineralizing it by a purifying and/or demineralizing process to produce a flow of purified, demineralized water (113); injecting carbon dioxide into said purified, demineralized water (113) to produce a flow of carbon-dioxide-enriched water (123); and finally passing the carbon-dioxide-enriched water (123) through a re-mineralizer (124) which comprises a dolomite medium (126), thereby producing a simultaneous remineralizing of the water in Calcium and Magnesium leading to a flow of purified, re-mineralized water (127).

Re-mineralized water comprising calcium, magnesium, and bicarbonate ions in a 1:1:4 molar ratio, said calcium, magnesium, and bicarbonate ions constituting at least 75% by weight of all ions in said re-mineralized water.

A method of and apparatus for producing electricity, hydrogen gas, oxygen gas, pure water using a geothermal heat are disclosed. A low voltage (such as less than 0.9V) is applied to a prepared solution containing hydrogen generating catalysts to generate hydrogen and oxygen. The hydrogen and oxygen are used to drive a gas turbine to generate electricity. The oxygen and hydrogen are combusted to generate heat and pure water. This process is advantageous in many aspects including desalinating salt/sea water using geothermal heat.
