Smart Burn

Found this in the local hardware store - some of you might have seen it on the New Inventors where it won an award. I'd LOVE to know how it works, as without knowing the science behind things I tend towards the skeptical, especially with such an impact as this has. It's a short metal tube with 'something' inside it that is placed in the firebox of a wood heater, but not near direct flame. It reduces carbon emissions from the chimney. While not an answer to burning unseasoned timber any reduction in emissions has got to be a good thing. So we spent the $45, cleaned out the chimney so it had a clean start and we'll check again in three months to see if there is any reduction in soot. We'll let you know. If you've already trialled this product please let us know how you feel its spiel holds up to reality.
