How about buying stock in a 7 year old established cutting edge technology company?
I'd say adultvest, which would then invest in a cutting edge high tech building a new factory to produce more product, but they can't seem to get their act together after a year and a half of communication. In fact, I really have only ever heard of one company, very recently, that they have actually invested in, so my suspicions are piqued.
So, cut out the middleman, and invest direct.
