Anyone have experience with these Ecozoom rocket stoves:
http://ecozoomstove.com? While they're heavy and not exactly built for backpacking, it looks like they're pretty versatile because they work with both charcoal or wood.
I have my MSR Whisperlite for when I'm counting ounces and packing light, but this seemed like a neat alternative for patio cooking or car camping that doesn't require propane or white gas. Any thoughts? Or has anyone used another rocket stove that they like better?
