I have been getting into electronics a fair bit in the last year. I always find Dave jones from EEVblog entertaining.

Dave does some simple back of the napkin calculations in this video to pull apart the claims of [reflectorbital](https://www.reflectorbital.com/)

I am just sitting here amazed that this idea got past the idea-stage for the startup.

I was entertained by the video - I think you might be too.
