Danger comes from energy density and ability to release that energy quickly. Fat doesn't explode. Neither does gasoline, though I wouldn't be comfortable carrying 11ml of gasoline in my pocket. Existing batteries sometimes do explode and cause injury. The problem would be far worse if they had 7x more energy in them.
- scottlocklin 7y agoI did use the example of gasoline, but I don't know why you'd be uncomfortable carrying 11ml of it in your pocket. Let's change it to 11ml of ethanol which is basically the same energy density. In principle you should be able to extract the energy using a fuel cell or even a heat engine. Since we're talking about futuristic cell phones, it seems more than possible to squeeze more energy into Captain Kirk's federationphone.
