Halogen lamp slurry warmer for manual brewing

[FinerGrind]

I was reading Barista Mag. this morning and was glad to see that they have added a new column on manual brewing called "One By One". A good start by a pub to finally capture tools and techniques for manual brewing.   What really caught my eye was the next article on Best Bar Tools.  A Barista put together a halogen lamp slurry warmer, and after reading / seeing it, I want to know what impact this would really have on the extraction.

Before going through all that, Cameron should consider keeping a cover on the Chemex to keep the heat in.

I think he is heating the slurry as he is pouring,  keeping the brew temp up, and can't use the lid yet.

Thanks for the link, it really is a neat coffee toys article; I couldn't help but notice the french press filter from http://kaffeologie.com/
They also have a vacpot variation, a metal pourover filter, and an aeropress mesh on the website ...

Right, it was his statement "lets me use a more reasonable dose of coffee" that I'm most interested in. Without getting all tied up in knots about the cost of power consumption v.s. over-dosing  (and I usually do over analyze) I'm interested if heating the slurry does help improve extraction (less time, smaller dose if temp loss during extraction is lessened?).  I can envision a heat coil that also acts as a base for your pour over, if that's the case...

Right?

Honestly, with due respect, this halogen thing is insane.

Ask just one question: which is faster, the rate at which water is flowing amid the grind, toward and through the filter -- or the rate at which the heat from this lamp is conducting itself upstream against that flow in hope of raising the temperature where the grind is being extracted by the flow?

The "lets me use a more reasonable dose of coffee" thing is a really troubling remark, from a standpoint of extraction theory and/or technique. I presume this is another "dry sidewall" technique, but how this method could possibly help with that is difficult to say.

This is simply absurd.
