Because I hold out hope it'll happen some day.

And within a decade of that day, if it comes from easily fabricated materials, money will mean nothing, and I don't care to fight with the crazies who will try to be hoarding it. A few thousand, or hundreds of thousands, would probably be easy to acquire, millions feels like too much work, even if it is worthless. I'm thinking about my future (dream) spare time (also a dream), and I don't want to commit future me to coming up with those amounts. I'm sure future me will have a few hundred for anyone if anyone ever took me up on my offer.

So my offer stands at 100:1, because I'm serious about paying out on it when it happens, when else do you get genuine offers at those odds? Give me your dollars.

A room temperature super conductor, would revolutionize power generation, computation abilities, transportation, communication, space exploration,

There's only a few industries that would not be completely up ended by a room temperature super conductor. Mostly the humanities, maybe biologies and politics. Global warming will have been a blip on the extended history of Earth, we will be terraforming other solar bodies quickly because of the reduced cost to exit earths gravity wells, Voyager would only be the furthest space craft for another decade, if that.

There would be some people who try to stand in the way of progress, but if it's shown to be easily produced and scalable, we're going to be in a star Trek universe (other theoretical extra terrestrial species would also be able to create these technologies theoretically) within a generation, probably our generation if you're around my early middle age.

Money will be a nothing in a world of such technology.
