Honey, please light the Ethanol

< Smart FireA design group has come up with the perfect solution for those people who want the appearance of a fire, while reducing the risk of poisonous fumes and the mess of combustion. It is called “EcoSmart Fire” to emphasize how smart it is to have an Ethanol flame burning in your house.

My first questions were, of course, what is the actual heat output of this thing and whether it is practical to assume a ready supply of denatured ethanol. Unfortunately this is probably the wrong approach to this new technology — finding a way to enhance the ambiance of a space already running on central heat seems to be the main point, with only a very basic level of practicality, safety, and sustainability in mind.

Nonetheless, I found that the FAQ says the flame can “produce 14Mj/h equivalent to 13000BTU”. Not bad for a small room. Come to think of it the average PC power-supply generates about 1500BTU to 2500BTU but even if you ran five or so PCs to keep you warm you would still be on the grid and you couldn’t “safely” burn stuff. On the other hand, if you live in more than a 500 sq/ft bungalow you might need to invest in a lot of small fires, which just begs the question of whether you can run these fires from a centralized control system to manage output, burn-rate, etc. or if you are just supposed to setup a fire on its own in each room, as the Victorians did.

The marketing blurbs claim this really uses a renewable energy as the source of fuel, but burning wood is like burning ethanol in that regard, eh?

In fact I read that Alaska’s Senate passed a law recently (bill 337) to promote creating ethanol by processing waste wood with fish parts. So the comparison must be intended for petroleum or natural gas based fireplaces, not wood fires. Is that a big market?

Come to think of it I’m wondering why someone hasn’t yet figured out a way for restaurants to recycle their own cooking oil into beautiful and firery displays of ambiance. And if ethanol is actually available, then just mix it with the waste oil from food preparation and you end up with a convenient fuel for running your fireplaces as well as your vehicle…biodiesel.
