Apparently,
Also, what is this HHO stuff it is talking about?
Of course normal water is H2O, two Hydrogen atoms covalently bonded to an Oxygen atom. Writing it as HHO almost implies that the Hydrogen is the central atom in the molecule (for example, writing Sodium Hypochlorite as NaOCl instead of NaClO) with the Oxygen with another Hydrogen atom covalently bonded to it (not something that is prone to happen considering Hydrogen only needs 1 bond to fill its S orbital).
It claims this HHO is a gas, which would imply that the intermolecular forces of attraction between the molecules are significantly less than water. The Hydrogen bonded within the ordinary water molecule keeps it in the liquid phase when it would ordinarily be a gas at room temperature. HHO apparently lacks this Hydrogen bonding, which I guess would make sense, sort of, since the Oxygen might not be the central atom any more (assuming that is possible), but you will still have a an electronegativity difference between the “central” Hydrogen and the Oxygen, making the Oxygen side (along with its unbonded electron) negative, leaving the other side less negative, if not positive.
