They are asking researchers to come up with a nanoparticle transducer that has single-neuron resolution, which can be ingested or injected into someone (that is, introduced into the body non-surgically), bypass the blood-brain barrier, self-assemble in the brain, and facilitate two-way communication with neurons via an external encoder/decoder system.
Which part of it refers to a 24-52 GHz antenna capable of power delivery over ~500ft distances? You know, the 5g nonsense that you claimed is simple?
And yes, it's a grant proposal, meaning as recently as 2018 they didn't have anything even with a helmet. So I guess thanks for debunking yourself.
