// Update the amazing Universal Storage wedges for use with

// Author: Paul '@pjf' Fenwick
// License: Same as RealismOverhaul itself.

// The fuel cell rates are based upon the Apollo service module
// settings by RedAV8R, and feedback from Paul Kingtiger, the mod's
// author.
//
// For a 1kW output, the following standard rates are used:
//
// LiquidH2       = .0000584244
// LiquidOxygen   = .0000443399
// ElectricCharge = 1
// Water          = .0000443654 (3.833 litres/day)
//
// A kerbonaut requires 1.7 litres/day of water, so a 1kW
// cell can sustain a little over two kerbonauts in water.
//
// The US cells themselves are about half the size of an Apollo cell
// (assuming each wedge holds about 40-50cm diameter sphere), and Paul
// has indicated they're modelled after an output of ~ 528W.
//
// For ease of management, I'm making the cells have an output of
// 500W. This is enough to sustain one kerbonaut in water, and
// makes power planning and maths easier.
//
// The cell is designed with basic reserves to produce and hold one litre
// of water. This would require:
// 
// LiquidH2     = 1.3168906499 litres
// LiquidOxygen = 0.9994248931 litres
//
// Tank wedges are modelled after water wedge being able to hold 58
// litres of water, which is in the original part definition, and
// consistent with a spherical tank ~ 40cm in diameter.  LOX and LH2
// wedges contain enough material to produce one water wedge after
// processing through a fuel cell.
//
// A example Life Support octo-core could consist of:
//
//  - 2 x Fuel Cells (supports 2 kerbonauts in water)
//  - 2 x LH2 (fuel, 15 days with both cells running)
//  - 2 x LO2 (fuel, 15 days with both cells running)
//  - 1 x LO2 (breathing gas, 30 days @ 2 kerbonauts)
//  - 1 x Water (start empty to avoid fuel cell overflows)
//
// This core does not manage waste (water, solids, CO2), but
// the next release of US looks like it might have parts for that. :)

    @description = This small fuel cell consumes hydrogen and oxygen to produce potable water, heat, and a moderate electrical output. Rated to 500W, and with water output enough water to sustain one kerbonaut, this cell has integrated resources to run just over twelve hours. Although much safer for Kerbals than RTGs, please don't tease the stirring fans.
