(Business 2.0) -- Asking venture capitalists for great startup ideas is a little like asking Curt Schilling what pitch he's going to throw next. When we posed the question to dozens of VCs and investors around the country, more than a few indignantly shot back, "Are you out of your mind?"

But after some friendly prodding from our reporters, a surprising number of them couldn't help but start jawing about companies they would love to build - if only the right people could be found to perfect the technologies or the business plans and make them seem possible.

To see which ideas these VCs will fund for a total of $100 million, click here.

The result is this list of 20 tantalizing business ideas, ranging from a host of new websites and applications to next-generation power sources and a luxury housing development.

This isn't small-time thinking, either: These investors - which include some of Silicon Valley's most successful VCs as well as serial entrepreneurs like Steve Case and Howard Schultz are backing their ideas with a collective $100 million in funding to the entrepreneurs who can get them off the ground.

We don't guarantee you'll land a multimillion-dollar payday or even get your foot in the door. But with the ideas now in your hands, consider yourself halfway there.
