Google behavior when there are two DUPLICATE web sites?

Hello, I have a blog YYY.com

I would like to buy a new domain (good keyword) ZZZ.eu or ZZZ.com

I would like to put in the new domain the SAME blog content of the YYY.com domain.

Google penalizes domains that have duplicated content in the same domain. How does it behave when it sees that there is another domain with the same content? (eg. for every new post in yyy.com I put the same post in zzz.eu) ?

Adsense will be ok? What about indexing and ranking? No penalties?

Same situation, Google will see it as dupe content. The fact that the site will have ideantical content to the other and no other original content will make matters even worse.

You can probably get it indexed, maybe even ranked, but you won't be doing yourself any favours and it's going to be a lot more effort than with unique content.

Ok... so what do you think about it strategy:

1. Create a static page which talks about the original domain
2. have in the middle an RSS feed that reads the feeds of the original domain and shows the titles + maybe some snippet of text

Would that be good? The automatically updating feed would (I suppose) create always new up to date content for google.

Would it work fine?

Do a simple HTTP 302 redirect to the original site? No dupe penalty now.

Any reason why you must put the same content??
