Entry:

This past week, I learned that summer in Ithaca is much quieter than during the fall and spring semesters, but has much nicer weather and beautiful scenery. On the other side of the window, the second Dry Lab meeting was in session. Manny and Kelvin had come on board the Dry Lab team recently. Introductions aside, all of us took turns presenting our findings on pumps, filters, batteries and other components that would go into our biosensor system.

For the power source, there were 3 different types of batteries to consider: lithium, lead acid and silver ion. Tina informed that silver ion would be most expensive as it was still relatively new technology. However, it was the most energy dense source. Between lithium and lead acid, lithium has a greater power-to-weight ratio but lost its capacity to hold charge even when not in use, while the lead acid was clunkier (heavier and larger) and better equipped to deliver large jolts of power.

For food delivery and water filtration methods, we began a discussion about a combination of pump and gravity-fed designs to save power and extend battery life. Related to that matter, we talked about discrete versus continuous flow of food and water into the bacterial culture but were cut short on time.

At home, we continued research on our assigned components, looking mostly at product price, functionality and performance.
