And I think that's why you don't see that kind of energy storage happen in a home very often. - Natural Gas is brought in through VERY small pipes, and is never kept anywhere, it's just used immediately. - Jerry cans are found regularly but are also sealed up as much as possible while still remaining usable. - Vehicles have sealed fuel systems, and are designed to not allow the fuel to combust all at once if at all possible. In fact, now that I'm thinking about it, pretty much the only time you hear about homes exploding/bursting into flame/etc. is when one or more of these systems is compromised.
