First the water has to be at the right temprature to weaken the covalent electron bonds. In liquid water, the excited OH-stretch vibration relaxes by transferring energy to an overtone of the H-O-H bending vibration.
However, as the temperature increases the hydrogen bonds of water get weaker, which leads to an increase of the frequency of the stretch vibration and a decrease of the frequency of the bending vibration. As a result, the overtone of the bending mode shifts out of resonance with the stretching mode.
The magnets or electromagnets are used to align the H2O molecule.
Water, being dipolar, can be partly aligned by an electric field and this may be easily shown by the movement of a stream of water by an electrostatic source. Very high field strengths are required to reorient water in ice such that freezing is inhibited. Even partial alignment of the water molecules with the electric field will cause pre-existing hydrogen bonding to become bent or broken. The balance between hydrogen bonding and van der Waals attractions is thus biased towards van der Waals attractions giving rise to less cyclic hydrogen bonded clustering.
See one of the following links to understand the electrical and chemical nature of water.

Once the molecules are aligned and heated to the optimum temperature they are fed through a small opening passing a set of small electrodes and instanly turn into hydrogen and oxygen. The hydrogen generation process is controlled by pulsing the DC to the pump motor and to the electrodes independantly so we can control the flow of water or KOH and production of hydrogen. 1 liter of water can produce over 1600 liters of hydrogen and over 600 liters of oxygen. So we dont need a lot of water in the chamber to produce a lot of hydrogen we only need a lot of reaction....... We can keep all the water we want in a reserve tank.
The aluminum can and KOH reaction is best explained by this link.
