A pizza delivery guy built his own insulated bag with a Bitaxe miner tucked inside. While he’s out delivering orders, the rig mines BTC—and the heat it throws off keeps the pizza nice and warm.

How it works

The bag is rigged with a compact Bitaxe ASIC that cranks out up to 4.1 TH/s and draws about 74W of power. All that mining heat means your pizza doesn’t get cold on the road: according to the creator, the bottom of the bag stays around 40°C.

Why bother?

This setup kills two birds with one stone: the courier keeps the pizza hot using the miner’s waste heat, and earns some Bitcoin on the side. It’s a clever way to put mining heat to work, without adding any hassle to the delivery process.
