Quote: "If you manage to develop a condom that guys won’t complain about having to wear, you will win $100,000 from the Gates Foundation ..."<p>This is misleading, verging on false. What's being offered is not a prize for a successful design, it's a grant to support development of a promising idea. You don't submit a finished design and wait for your $100K "prize", you submit a proposal for a research program and hope it merits support.<p>In other words, it's not a lottery, it's science.
