No, it&#x27;s impossible.<p>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.<p>For instance, it&#x27;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&#x27; Law.<p>There are many things that are hard but cannot be ruled out, like sending probes to Alpha Centauri. It&#x27;s fair to spend energy thinking about those ideas, but to do that we need to stop thinking about things that are ruled out.
