Elsewhere I mentioned that during the post-hurricane blackout (folks we conversed with at the restaurant where we dined last night were out for 8 days.. and for some others this was the second time, having lost power for days just a couple of weeks earlier) I came to the conclusion that we needed an easy, quick non-electric way to make coffee and tea short of breaking out and filling the kerosene stove... especially for mornings where that's the only need (usual, for us), and we suspect the power won't be out for long. To that end, based on pleasant previous experience, I bought a small stock of Esbit tablets, a stove and a spare (they're cheap).

Recently, though, I came across references to "Storm Kettles" and "Kelly Kettles" that , though designed for outdoor use,seem like they'd be a very efficient indoors using (non-toxic) Esbit tablets for fuel. I found one reference to using them with "hexy" tablets, which I think are similar.

The "Storm Kettle" seems rather expensive (over here), the one retailer I've found selling them for just under $100 USD. The "Kelly Kettle" looks to be a bit cheaper, at around $70.

These devices seem to be almost unknown on this side of the pond- anyone from the UK care to comment on them? Is one better than the other? Any tips on usage?

Thanks in advance.
