Hi, not sure how you came to the conclusion that "still require local storage or generation resources at the receiving end". the whole point is replacing those with a steady connection to the national grid. the only difference being it would be wireless rather than copper based. A transient object like a bird would not have a significant affect on continuity of supply. it is very small compared to the Tx/Rx surface and doesn't linger in the beam path. Wouldn't you agree that replacing expensive imported polluting fossil fuel generation with a cleaner and cheaper locally sustainably generated energy is worthwhile?

Is the Rf exposure to the bird significant?

  Else where in thread someone said 100 mw/cm^2. Not great, not terrible. Maybe 1/5 of putting bird in a microwave. Cooking time would be long but you may be able to get it to work

    Frankly, I have concerns about birds. Insects are sub wavelength, so they won't be impacted, or at least the impact won't be obvious. But the birds moving around... Guess we shall see. That's what field tests are for.

> doesn't linger in the beam path. You cannot guarantee this. The bird could decide to fly directly down the beam path and there's nothing you can do. Directly from the article: > The system uses a net of lasers surrounding the beam to detect obstructions, like a bird or person, and it automatically shuts off transmission until the obstruction has moved on. Since there are so many possible obstructions that could occur, I suspect that the link will continuously turn on and off. This will be worse than before so you'll need local storage or generation to account for these unplanned outages.

  Being wireless it would be easier to set up redundant links.
