Aluminum allows for the flow of electrons while glass does not what an aluminum wire surrounded by glass being effective design for a device that will need to carry an electric current

One possible design could involve using an aluminum wire as the conductor surrounded by a glass insulating layer. This design would allow for the flow of electrons through the aluminum wire while providing a barrier to prevent the current from leaking out or short-circuiting. The glass insulating layer would also protect the wire from external elements and prevent any potential hazards.

This design could be particularly useful in applications where electrical conductivity is required but insulation is also necessary, such as in electronics, sensors, or other devices that require precise control of electrical currents. Additionally, the use of aluminum as the conductor would provide good conductivity while the glass insulation would ensure safety and reliability.

Overall, the combination of aluminum wire surrounded by a glass insulating layer could be an effective design for a device that needs to carry an electric current while providing protection and insulation.
