SpaceX's thrusters are achieving 1 kW/kg (after inefficiencies).
That is THREE times better than the best electric thruster at NASA; the NEXT-C used in the recent DART mission which achieves 342 W/kg (effective).

Stacked diode bars for high powered defense lasers:

Water-cooled modules with copper heatsinks achieve 1.5 to 2 kW/kg when producing near-infrared beams with efficiency close to 65%. They're coupled to fibre lasers for ~30% overall efficiency.
We must study 'chronobiology': how the immune system, metabolic rate, cell repair and many more processes are affected by the circadian rhythm, which is regulated by the suprachiasmatic nuclei in the brain and the Dracula hormone among other things.

A two-stage method for producing brilliant gamma rays:

A pulsed laser is used in a Plasma Wakefield Accelerator to produce high energy electrons, which are then converted into y-rays by another plasma.
Efficiency is 0.4 x 0.1 = 0.04 for the plasma stages.
Most of @cern LHC's length is occupied by superconducting dipole magnets, totaling nearly 20 km.
They're 15m long, weigh 35t, store 7 MJ of magnetic energy and generate 8.33 tesla fields to bend the accelerator's 6.5 TeV beams.

NASA is already detailing plans for the JWST's successor. LUVOIR will have a 15m diameter mirror and UV to IR wavelength sensors, to produce high res images of our Outer Solar System or even make out details on exoplanets.
Here is the massive final report:

These lightyears-long features point to protostars usually hidden by a swirling cloud of dust.
