Hi everybody,
The "scream 'o flashlight" is (Just basically screaming like a club of wild maniacs into a speaker and on the output side, it lights up a bulb.) The big concept is to set the device up wherever there is a lot of constant ambient, loud noise; like Niagra Falls, lumber mills, factories, tunnels where cars are rumbling through all the time, etc.......free energy converted from ambient noise...... :)
Kind regards, (itsblockdog) on youtube My name is Ronnie
