Rear wheel power spoke pattern This is my first time posting here.

I have been biking for a few years now and learning little by little how to  repair my ride myself.

My latest problem is 4 spokes of my rear wheel (36 spokes) broke, making it like a potato-chip. 

It's a pretty old aluminum wheel but people told me the rim and hub were good, so I figured I might as well try to repair it, considering how cheap a spoke is, at least it would be a good learning experience.

I tried the traditional 3x cross but half way through I read about the powerwheel pattern on Sheldon Brown's website, 2 pulling spokes for 1 pushing.
But that is the only information I got.

I'd really want to try lacing my wheel that way but am clueless of how to cross spokes (over, under...) and I don't know what length to buy, etc.

Would anyone know how to do or is it held secret because patented and my only option is to buy one somewhere?

Cheers
If you are only replacing the 4 broken spokes then you will need to duplicate the wheel's spoke pattern. 

If you are re-lacing the wheel with new spokes, a 3-cross spoke pattern is time proven pattern that is great for a first time wheel build. It is easy to implement, it builds a very strong wheel and it makes re-truing the wheel a straightforward.  All of these are great features for your first wheel build. 

After building, ride it a bit, and see how you did before trying to chase more exotic spoke patterns. 

My reading of Sheldon's  POWerwheel page is that the pattern is a bit of a joke, but may actually work.  Even if it does work, it wouldn't be a good first time build as tension the wheel would be more difficult than a standard symmetrical pattern such as a 3-cross.

Update: check Jeffery Bell’s answer this was an April fools day joke (it’s a bit hard to spot now with all the ads, but at the bottom it is dated for April 1. Crazy that some have apparently tried the pattern  in real life.
