AI Technical Summary
Existing trucks using lithium batteries face limited range and weight constraints, while hydrogen fuel cells require rare earths and depend on external hydrogen supply, which is scarce.
An e-truck with a hydrogen-powered Wankel engine generator as a range extender, supplemented by a battery for excess energy storage, and PV cells on the roof for additional energy, along with an inexpensive hydrogen production system using magnesium paste and water.
Enhances truck range beyond battery limits and reduces dependency on external hydrogen sources.

Abstract
Description
[0001] The transport of goods by truck on the road is also intended to become climate-neutral. Trucks with lithium batteries or trucks with hydrogen fuel cells, which also provide energy, are being tested.
[0002] When using batteries, the range is limited and the weight of the batteries reduces the payload capacity.
[0003] Hydrogen fuel cell technology requires rare earths and is dependent on other countries. Furthermore, there isn't yet enough hydrogen available.
[0004] My idea is an electric truck with a hydrogen Wankel engine generator (range extender) that provides enough energy to run the electric motor(s). Excess energy is stored in a battery. The battery can also supply energy when energy is needed beyond the generator's output.
[0005] PV cells can provide additional energy on the roofs of trucks and trailers.
[0006] The Wankel engine generator technology (range extender) was implemented by AUDI in an A1 e-tron in 2010. Unfortunately, the prototype never went into series production.
[0007] In addition, my new Mazda car will be delivered in 2024 with a rotary engine range extender. Currently, it runs on gasoline, but the rotary engine can also run on hydrogen.
[0008] The range of trucks can then exceed the range of batteries.
[0009] Any company could produce hydrogen itself using the "Cost-Effective Hydrogen Production Plant" (DPMA, DE20 2021 002 421.2), or in the future, they could purchase the "Hydrogen-Magnesium Paste" patented by the Fraunhofer Institute. All that's needed is to add water, and the hydrogen is released.
