A Simple Bi-Polar DC Input Active Rectifier Circuit

I came up with a pretty simple circuit that I thought I'd share. This circuit allows the use of any polarity DC connector without a diode drop and draws practical zero current draw. There seem to be many benefits with this circuit and minimal downside, It also rectifies AC if you increase the bulk storage capacitance.

Feel free to build and use, hope folks find this useful and/or cool.  - Travis
