Downhill wheat milling or cooking using friction from braking on long stretches of downhill roads. Truck trailers converted into industrial mills or ovens.
Take a full trailer of wheat uphill and return with flour.
Industrial machines use a lot of power. This is one of the factors that increase humanity's total power demand and present a hurdle to powering society solely from renewable sources.
In suitable locations, this could provide cities with daily demands of cooked rice or flour.
How it works
In suitable locations with long stretches of downhill roads convert truck trailers into industrial machines that use friction from braking to power the milling or heating of the cargo. On the way down the truck would not use normal brakes at all. Instead, the trailer wheels would be connected with gears to power the machine inside. The gears would be designed for the specific road so that both the vehicle speed and the machine inside the trailer are rotating at optimal speeds. For the machine inside to operate at ideal rotation per minute the truck would travel downhill at the legal speed limit.
Additional downhill weight
When going downhill, there could be additional (passerby) trucks linked behind the trailer. The entire composition would then rely on the trailer-machine for braking. That would increase the work potential for the trailer-machine while saving the other trucks' brakes.
Some examples of suitable roads
117 km (72 miles) in Peru between Concocha and Paramonga. The starting point is at 4095 m (13440 ft) altitude, and the end is at 16 m (52 ft).
40 km (24.8 miles) the longest and highest paved road in Europe is the Pico Veleta.
38 km (24 miles) Haleakala on Maui, Hawaii.
and so on
Other use case scenarios
industrial food processing - cooking anything on the heat created by friction
Water heating. An empty tanker goes uphill. There it's filled with water. The water gets heated on the way down. At the destination it gets added into the communal pools, or tanks of centrally heated buildings, neighborhoods, etc. Then the truck goes back uphill, empty.
