Why exactly must each idea have a domain name? How about prioritizing your ideas some more to cut down on them? You can't possible have 50 equally good ideas. Also, you can get .INFO domains for $1.99 so even if you have 50-100 domains that's fairly affordable. Can't imagine you would be able to rent a domain cheaper than that.
