It is probably helpful to treat people who are bright eyed and bushy tailed but uninformed as being worth educating and worthy of receiving a very small part of your knowledge, rather than as targets for ridicule. Especially so when they may not even be aware that they are being made fun of. I "invented" a "perpetuum mobile" (involving a transformer to step up the voltage to overcome losses) when I was 10 years old and my school teacher was able to explain that it wouldn't work but couldn't tell me why. It was at least helpful then to know that there were extra things that I needed to know, rather than simply being encouraged to further my education by learning the totally hard way that the idea was wholly impractical. Or being encouraged to attempt to patent it. FWIW, re perpetuum mobile and friends, there is no reason that energy cannot be created or destroyed within the universe that we know. It's just that we know that, using the mechanisms we know about it's impossible AND we are highly confident that such effects are unlikely to be accessible by any technique a novice is liable to stumble over. More importantly effects which APPEAR to be PM but aren't, may lurk undetected waiting to be discovered. Nuclear fission and fusion and the utilisation of zero point energy (eg Casmir effect) were and are, respectively, in the same category at this stage. Relativistic effects had the same standing in pre-Einsteinian times. Similarly Quantum Mechanics, which nobody understands (or, according to the Copenhagen interpretation, can understand).
