Sprinkler in buildings or a home: Why dont you get those lawn sprinklers which must be very cheap and place them in buildings and attach it to a hose...And attach it to every home...To prevent fires...Because the regular sprinklers to install must cost a fortune...

You could even place dozens of those lawn sprinklers in a home...You could even attach it to a Tank that is placed upsided down and releases a certain quantity per microsecond...All that is needed is the: smoke alarm thing to go off....

to prevent house fires...
