We encountered various problems when tasked with creating a safe light source in a house with no electricity. All of the resources we were given were flammable, so we were not able to construct a prototype that successfully contained a flame. Furthermore, we had limited time to come up with any viable solutions to our problems. From the experience, I have learned that with limited resources and time, it is very difficult to construct an applicable prototype. Concerning the invention of the train, limited time played a factor in its production. Businesses were becoming much more global and needed an efficient way to move their inventories. The train was a worthy product that adhered to the needs of the businesses at the time. It was, and still is, able to transport goods very long distances with minimal cost and minimal time.
