Archibald is probably referring to this: https://www.secretprojects.co.uk/th...ough-makes-lithium-ion-tech-90-cheaper.34656/
It may have an impact on exoskeleton technology in the short term as well.
In first half of 60th, in NII-100, worked at 500-kg armoured exoskeleton, with small ICE, machine gun and AT weapons in hands.
A few years ago, in Russian Federation, also, started works at military exoskeleton with ICE.
Speaking of small ICE, is there much in this or any of the other topics on very compact microturbines? We're working on a 30kW 2kg motor generator module with inverter but looking for decent turbine partner.
