I know little about circuit design, but can build them. Maybe this would be a good challenge for someone.
What I need is a power supply circuit with a 12 volt output that will run a laptop for several (many ?) hours off of any reasonable number of large (liter or so size) capacitors. The reason is that I need a power supply that recharges very quickly and is easy to carry by hand on mountain trails to get it charged - assuming such a power supply would be light enough (40 pounds or less) to be portable. Additional circuits running off the 12 v. circuit to supply both 5 v. and 3.7 v., both at 500 miliamperes would be nice too, though I could probably find those somewhere to easily incorporate.
I know the dangers of large capacitors and can deal with that with a plastic box. I'm a practicing coward, and am not about to short myself across the leads![Cool :cool: :cool:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Can somebody help? If you put a solution here, email me at:

and I can come out of the mountains here in India and check the site. Emailing the circuit diagram will not work, as the email is retrieved over a cell phone.
Thanks ! !
