Ask HN: (What) would you use a sub $9 disposeable location tracker for?

I have a prototype location tracker that costs <$4 to build. It can track any item's location every hour in urban areas for 30 days world wide (connects via wifi). Its smaller than a walnut. Would you use it? If so what for?

    If it could work in rural areas, then cows... my uncle spends several days on horseback every year trying to round up his cows. If he could know exactly where the cows were it could save him days. If I’m stuck to urban areas, maybe look at dogs cats and carrier pigeons.

    How much longer could it run for it used some energy harvesting and/or only reported once every 6 hours?

    What if an open wi-fi network is not close?

    Seems it will only work around your house or maybe Maccas, really needs 3G to be useful.

    My dog's collar. My car. My camping backpack.
