I really love this concept! So much heat energy is lost from flame, so it makes a poor means of illumination. Using that heat to power LED bulbs is clever.
I wonder if there may be a way to further optimize this. The wick flame component is exposed and gives off light, but would it make sense to totally contain this part, whereby no heat escapes (e.g. no glass) and the sole source of light is from the LED bulbs? Also, within the “furnace” component, you could incorporate a piezo electric spark generator, so that no matches are required.
My campaign is live in kickstarter as mentioned above. It is a pre-sale scheme more or less for reasons explained there.
Feel free to participate and eventually get one.
First, in that lamp the flame is wonderful to look at. If you hide the flame… or just make it a complete combustion’s blue flame then half of the magic is lost. Look my views on flame and burner here: The Burner - Barou's Thermoelectric Lamps
I am really considering in my next models having an AAA battery for easier start-up, but again i am double thinking against making the lamp more complex and stealing the firing up ritual.
Lastly, with kerosene or liquid wax as a fuel, a piezo throwing a spark would not do the trick. It takes a mini high voltage transformer, and a robust li-ion cell so as to provide a streamer of high voltage thus igniting the wick. Can be done of course, but i would prefer this to happen in a future thermo-model like a chandelier.
