What's up with these new "cold" soldering irons?

Maybe they aren't really new, but they're new to me.

Is there some sort of alloy shield over the tip that doesn't absorb heat or cold that cools immediately when the heat source is gone or something?

Why dat do dat?

This is claimed by the manufacturer -

"The Cold Heat™ tool's patented technology creates
the heat you need to solder within seconds, and its
cordless design lets you operate it anywhere for l
ight-duty soldering projects.

The patented Split-Tip™ combines unique material
properties into two electrically insulated electrodes
that form part of an internal electrical circuit. When
the tip's two electrodes make simultaneous contact
with an electrically conductive material such as the
work piece (wire lead, terminal, solder, PCB pad, or
other material), this circuit is completed and the high-
resistance electrodes generate instantaneous heat at
the tip. The heat is then rapidly transmitted to the work
piece to complete the quickest soldering joint possible".

I watched a demo at the local building supply house sometime
back. The demonstrator gave his pitch and let anyone who
wanted, to use the device. One out of maybe 12 or so persons
touched the tip after their use on 22 gauge material and he
got a 'felt hot' feeling. The device held 4 double AA's and from
what I saw, it eat them alive. Claims 800 watts but I bet it did
not get 10 watts.

I think that I will stick to my rechargeables and wired
soldering irons, thank you!

Thanks Ed,

I guess the old "too good to be true" axiom holds here too.
