So, in my setting, there is a certain kingdom, which is capable of producing a special sort of liquid, that is seemingly not compressible, however, it actually "charges" up when compressed, and when exposed to some form of trigger, the liquid will then violently expand outwards with the work of the "stored" compression.
Said liquid runs on magic, so no need to think too hard about how it works. What sort of implications might such a liquid have on the general economy and industrialization of the kingdom?
- The Liquid Potential Energy (LPE) has the same density as water, of 1 g / ml
- LPE is completely chemically inert, and and does not react to anything chemically. IE rusting, tenderizing etc.
- LPE is found naturally in pools in underground caverns, and is not particularly expensive to collect
- LPE is clear when uncharged, and becomes completely opaque when fully charged.
- LPE is capable of storing up to 10 kilo Joules of work per milliliter
- To discharge the energy in LPE, you need to jolt it with some electricity, usually by magic
- LPE discharges completely and absolutely, it cannot be half-discharged, and will discharge all energy from connecting bodies of LPEF when triggered.
- LPE discharges itself by expanding its volume rapidly, not unlike an explosion.
- LPE is only charged when it is actively compressed, standard atmospheric pressure is not enough to start the charging process
- The LPE is initially at 10 kJ/ml, however, feel free to hypothesize scenarios if it were higher, as many pointed out diesel has a higher energy density
- LPE after discharging, returns to it's clear uncharged state, and can be readily recharged and discharged infinitely
- LPE discharges 100% efficiently into kinetic energy that expands outwards. It is visually similar to an explosion, minus the ensuing fireball
- LPE when first collected from the underground is already fully charged.
