Sciency Words: Compulsator

Sciency Words Logo

Science fiction uses scientific language as a form of artistic expression.  With that in mind, today’s post is part of a series here on Planet Pailly called Sciency Words.  Every Friday, I’ll bring you a new and interesting scientific word to help us all expand our scientific vocabularies together.  Today’s word is:


Compulsator: (noun) a device used to collect energy from a low-powered source then release it as a high-powered pulse.  The term is short for compensated pulsed alternator.

Think of it like a savings account at a bank.  If you deposit a small amount of money each day, at some future point in time you’ll be able to withdraw a large sum of cash for a major purchase.  In a similar way, by accumulating small amounts of energy in a compulsator, you’ll be able to generate a huge burst of power later on when you need it.

The most common use for compulsators is in a weapon called a rail gun.  The compulsators store energy as inertia in a spinning rotor then release it all at once to fire a projectile.  At the moment, rail guns are still experimental, but they—and the compulsators that make them work—will probably be common terms for soldiers fighting in futuristic, Sci-Fi wars.

Did you already know this word?  If so, please share another sciency word in the comments below.  That way, we can all keep expanding our sciency vocabularies together!

P.S.: I decided to focus on the term compulsator rather than rail gun today because a) I think the word compulsator is less well known and b) in the future, I suspect engineers will integrate the compulsator into other new weapon technologies besides the rail gun.

P.P.S.: At the moment, I have yet to find an example of a compulsator being used for a peaceful purpose.  If anyone knows of one, please share it in the comments below.
