This may be one of the neatest looking devices ever.  Here are some bullet points about 24V Q2 Charge Accelerator and enjoy the video:

• It is not a perpetual motion machine which are cool btw
• Will it run itself and recharge itself – yes
• Will it recycle its own energy – yes
• Will it do the above forever – eventually it will dissipate the power through the coils in the video
• Uses Maxwell Tech ultra caps (and capacitors are not the same as batteries)
• Batteries used stored energy via chemical reaction, the ultra caps are electrostatic
• The ultra caps have a much faster charging time than regular chemical batteries
• The narrator bolts together 2 quanta chargers
