[Vwdiesel] More on radiator as a battery (weekend science thread)

[Mark Shepherd]

Ah! several people have pointed to the 'Evans' site for
their coolant alternative. I'm not particularly impressed
with the sense of  uniqueness that is portrayed by their
site... All it seems to me is an Ethylene/Propylene Glycol
mixture which for the NPG+ is improved by 32% on NPG for
thermo-conductivity (from what initial value?)... As pure
glycols are about 2/3 that of water and not much better than
half the SHC of water. Does this account for the offer to
sell a higher performance pump?

Anyone any thoughts of the reverse voltage idea to protect
the radiator?
