"No fuel to buy or carry
Our stoves cook your meals with nothing but the twigs you collect on your journey, eliminating the need for heavy, expensive, polluting petroleum gas. Quick to light, fast to boil and easy to use."
After pedaling 200 miles on the day, you'll go on a scavenger hunt for twigs, after a couple of hours gather an armful, and be able prepare a cupful of lukewarm tea. In the morning, hungry and short-tempered, you'll turn into a major pulluter when you empty out the fine white ash of the twigs that provided so little energy. Of course, the thing might work, at least for food (not the iPhone), if you were to carry hardwood or prepared charcoal to burn, not to mention the bulk requiring a trailer for your fuel alone. The weight of enough hardwood or charcoal for a tour will soon make a few gas cannisters seem like feathers. Someone's having us on.
