Shown: laser variant (left) missile variant (right) Sabre-class Corvettes Mass budget: Weapons: 30tons -4x 2.5ton laser turret (10tons) -4x 2.5ton coilgun turret (10tons) -1x 10ton laser or missile array Habitat and life support: 70tons -10organics for 360days -Provisions: 36tons -Habitation: 34tons Rocket-skiff: 30tons Scopes and comps: 10tons Structure: 90tons Engine: 45tons Radiators: 25tons 300ton dry mass 900tons propellant 1,200tons total https://strout.net/info/science/delta-v/intro.html Exhaust velocity, specific impulse and delta-V of my fictional rocket: Walk: 12km/s (1223s) - 16.6km/s delta-V Sprint: 8km/s (815s) - 11km/s delta-V Both variants of the Sabre-class corvette are armed with four laser turrets and four coilgun turrets in addition to their primary frontal armament. The pulsed laser turrets have an average output of 13.5MW, with a 50cm aperture and a frequency agile resonator permitting infrared to ultraviolet operation to ac...

FUTURE POWER SUPPLIES AND ELECTRICAL WEAPONS - From impracticality to superiority without exceeding the energy density of TNT!

I'm working on a future history project spanning the next thousand years, and I've had an interesting time working out the power supplies that will allow laser pistols and gauss rifles to eventually replace old style chemical slugthrowers. I wish to share my work for other writers who want to make their futuristic weapons a bit more realistic, or at least consistent. If my maths is wrong feel free to correct me. Modern power supplies are useless for the task - our capacitors dont provide enough joules and our batteries dont provide enough watts. Future power supplies may be able to solve this, but Routledge's Law claims that "Any interesting battery material for a laser gun would be more usefully deployed as an explosive warhead." I think that is based on the misconception that laser efficiency cannot improve beyond the present and that their only damage mechanism can be as a brute force "heat ray".  If Dr John Schilling and Dr Luke Campbell of Atomic Ro...
