The Maxablaster Torch was created by optics engineer Ralf Ottow and can produce a beam of light four miles long and is powered by a pack of 54 batteries.

Ottow stripped out the innards of a powerful commercial flashlight and switched in a mercury arc bulb, which generates light by creating an ultra-hot plasma between two closely spaced electrodes inside the gas-filled central chamber of the lamp.

This resulted in a brighter, more focused beam.









You shouldn't point the gadget to your plasma screens, mobile phones or other electronic devices because they would most definitely get toasted.

'It's not a torch you'd walk your dog with,' Ottow says. ' It would probably cook your dog.'
