must confess...I love all these 'Low-Fi living' gadgets... Think I'll stick to my double burner and grill though...
Could be a fuel save too. Stop bus to have a cuppa. Open beer, drink beer, no longer thirsty, no need to brew up, fuel saved! Works for me Edit: Drive off, get stopped, fail breathalyser, loose licence, save fuel save planet!
Made one of those earlier this year. Aside from sanding the logo off, it only took 15 minutes and I've used it several times when on walks. Mine fits inside an aluminium cup so the whole tea set up is nice and compact. Only takes 3-4 minutes to cook up a brew.
