No, it's impossible.

Engineering is not simply about having fantasies. A fair bit of what you do as a technologist is rule out things that simply are illogical. Perpetual motion machines, a way to calculate whether a program will halt, acausal filters, and so on.

For instance, it's impossible to construct a windmill that is 70% efficient. I learned that last week, so now I know not to think too much about it, other than noticing any refutation of Betz' Law.

There are many things that are hard but cannot be ruled out, like sending probes to Alpha Centauri. It's fair to spend energy thinking about those ideas, but to do that we need to stop thinking about things that are ruled out.
