Radio receivers are not power hungry. Even a small solar cell and battery would probably suffice.
I suspect that returning the signal to Earth would consume more power than the actual receiver part.
- Ginden 5y agoAre you sure about that? https://physicstoday.scitation.org/do/10.1063/PT.6.2.20190131a/full/ https://physicstoday.scitation.org/do/10.1063/PT.6.2.2019013... > In a breakaway session, a telescope engineer told colleagues that power consumption alone could cost tens of millions of euros each year, a sizable chunk of the array’s projected €100 million annual operating cost. If costs did not come down, the energy requirements had the potential to hobble or even sink the project.
- rtkwe 5y agoYou're comparing two vastly different types of radio observatories. That's for an array where you have dozens to hundreds of amps, signal processors and antennas that require power. This would be much closer to the Arecibo telescope or the Five-hundred-meter Aperture Spherical radio Telescope in power requirements.
