Reply to comment by TheSpittah in A “Green” Quantum Sensor. Researchers have demonstrated a quantum sensor that can power itself using sunlight and an ambient magnetic field, an achievement that could help reduce the energy costs of this energy-hungry technology. by MistWeaver80

This won't happen, what they did is find ways to replace lasers with sunlight, so that you don't need a laser with an external power pack anymore. It's not a new 'energy source', it's not even a new solar power technique. It's an alternative to conventional testing setups that replaces some power hungry components with systems that can use light from the environment and the Earth's magnetic field to operate.

If I’m being honest, I’m far from concerned about the amount of energy that research takes up

Lasers are horribly inefficient at converting power from your wall to actual output power.
