A self contained Nuclear Reactor more efficient? (Score 1)

One small step forward for convenience. One giant Leap backwards for energy efficency. Seriously though 8 ounces of mineral Calcium Oxide and enough packaging to kill several small African Tribes ('The God's Must be Crazy' anyone?). All this just to heat a single serving of your beverage of choice. It seems pretty clear why we havent seen such a simple product in our retail outlets before. Personally I think the merits of a more durable mutli use container with a self contained element (powered by electricity, butane etc.) outweigh the merits of this container 10 fold purely because of cost efficiency (let alone energy efficiency). I guess only time will tell us if it is commercial. How much are people really prepared to pay for convenience? I know I wouldn't want to be forking out for this stuff on a daily basis. On the plus side I doubt we'll have to wait long before some yank seriously injures themself not following directions and gets this pulled from the market.
