Humans got a breakthrough in energy production technology...but it's not the breakthrough the aliens were hoping for...

Sparks: Human Alex, what you wanted me to show?

Alex: Well...we finally moved on from boiling water...

Sparks four eyes start to sparkle from happiness

Sparks: SWEET STARS! FINALLY! What is it? Magnetohydrodynamic generators? Radiation absorbtion?

Alex: Ummm...our new method is a little unconventional...

Sparks starts to visibly waggle his tail

Sparks: OooooOOooohHH! Human knows how to intrigue! Zero-point energy? Or even maybe the myth of cold fusion will become real?

Alex: Well...not exactly. We learned how to use supercritical CO^(2) to...take heat from burning our waste...and rotate our turbines...at the very high speeds...

As Alex explains the supercritical CO*^(2)* turbines to Sparks, his eyes stop sparkling and his tail falls down

Sparks: FOR GLORB'S SAKE! YOU BALD MONKEYS HAVE ALL KNOWLEDGE OF THE STELLAR FEDERATION AND YOU STILL BOIL THINGS TO GENERATE YOUR POWER!!!

Alex: Please, calm down...it's still counts as progress...^(right)?

Alex visibly starts to back down and seek routes for retreat

Sparks: RRRRRRRAAAAAAAAAAAAHHH!

Sparks starts to chase down Alex, while shouting slurs and curses on his native language
