It seems contradictory that they're worried about power factor, and also want to force contestants to output nice clean sine waves. Best way to get a PF of 1.0 with cheap switching power supplies, is to send them a square wave...

The challenge is a challenge. The goal is clearly to produce usable power, not to need more filtering. While the requirements for this contest don't require grid-tie, that's something that can be implemented later.

I don't live there, but looking at some of the photos, is deforestation potentially part of the problem?

Yes. Don't listen to the sibling comment, which ignores the well-known fact that deforestation in fact was a contributing factor. Of course, if you actually wanted to know the answer to your question, you would have found it with google, dozens of times over.

I have the world's slowest blu-ray player, an original Sony. BDP-S300, I think. It lacks both ethernet and performance. Sadly, the Raspberry Pi lacks SATA, which is what the unit uses to connect to the optical drive. That gives it hack value, though not with R-Pi. I'd probably have to shoehorn something Micro-ITX in there, or use a laptop motherboard, as the optical drive is smack in the center.

I've bought just one Blu-Ray movie because the player is so godawful slow and I have to use a crappy remote with it. Ideally I'd be able to run XBMC on Windows (XP or 7) on whatever I stuffed into the case, and then I could use the android remote app. Right now my entertainment system is a mk908 running Finless 1.4 or so and it leaves a lot to be desired. Playing discs is one of those things.

Go ahead and do lots of work with almost no chance of payment.

If you aren't already working on this, or don't already have a pretty good idea with at least a fair chance of succeeding, then you're probably not too smart if you decide to take this challenge on. So what? There are those who are working on solving this problem already. If they have the means to produce a product, they're already doing that. If not, then this will give them some money for production of prototypes for larger systems, and probably attract some investment dollars from Google.

1. downtime is unacceptable for this application. this code controls so much, does so many things, and is so obscure (say it with me, payments processing subsystem) that to do ANYTHING to it is literally worse than pistol whipping the CEO's daughter.

Then you can't afford not to have a backup server and a development server. This point needs expansion :p

You are an insult to my intelligence! I demand that you log off immediately.

Working...
