Thomas Edison and Benjamin Franklin are well-known inventors. Considering the available resources of their times, they took the world to new places. Henry Ford did likewise. Not only is he credited for the first car, he also came up with the idea for assembly-line work.
Smaller inventions have impact as well. Think of the shoelace, the whisk, the cast iron pot. Roller skates led to roller blades. Did snowboards precede skateboards? Imagine how the chair lift changed skiing and the outboard motor impacted fishing.
Your task is to write a story in which your protagonist is either struggling to invent something, or has done so and is trying to convince the market that her product is worthwhile.
Make it interesting by showing the issues that are impacting the character. Let readers see the setting, but also hear words shared.
Tension will pop-up as your character interacts with the device and with others.
Have fun with this one.
