Booting OSX from TimeMachine backup on a Windows PC

Hi guys.

I'm trying to sort out a problem. I'm going travelling in April for a few months and I don't want to take my laptop with me as it's heavy and I don't want to risk theft or damage. I know that if you use a Time Machine backup to an external hard drive and plug the external drive into another Mac, you can boot the Mac from that drive and everything looks and feels as if it was your own Mac.

My question is, how can I do this from a PC? I am presuming that I am more likely to come across a PC in an internet cafe or something similar and I need to be able to boot OS X on a windows.

If anyone can help me out with this, I would be extremely grateful. Looking forward to your replies!
Thanks in advance
