candle heater?

Facebook does it again...
Several friends have posted the link to this video recently.


Is there something magic going on here?  In one word....NO.  I was almost tempted to experiment with the idea until I really started to think about it.  Candles can only produce X amount of heat.  All this really does is give a little more surface area to radiate off the heat instead of it shooting straight up to the ceiling (it's still gonna end up there, anyway).  It might work OK under your desk to concentrate the heat to keep your legs warm (don't kick it over) but it won't do any more to heat your home office than just burning 4 candles on your countertop.  One guy even has a website that sells fancy ones.  http://heatstick.com/_KanHeet01.htm  I really like the electric light bulb versions!  All in all, it is a very cute idea but pretty worthless as a viable heater when it comes right down to it.  I might have to buy a 100 pack of tea candles to see how many I need to burn in order to match my Mr.Heater Big Buddy on the low (4000 btu) setting.
