Learn how to get 50 v dc, 120 v dc or 220 v dc from just your simple phone line! Enough power to light a 100 watt light bulb. We have developed a way you can use this energy to recharge 12 volt car batteries when used with a 115 v ac inverter system. Great for home emergency lighting! It is true we have lit up 100 watt light bulbs as well as neon and florescent bulbs. We use a very special design. Only our special circuit design will give you these results! and as far as we know it is all legal! as long as you use a safe diode to keep the back emf from going back into the phone line no one will complain or know it. very easy to construct! If you have 2 phone lines you can get 2 times the power amperage and voltage output. It does not matter what type of land line phone you have.
