My initial idea about the measurement project is to explore the electricity of biology and bacteria around us, such as mushrooms, algae, etc. Some questions came to my mind, like how to measure their metabolism and photosynthesis process? Voltage, capacity? What about sulfur bacteria and iron bacteria?

No specific number from the paper, the method seems still under developed.

I bought an oyster mushroom mycelium pack from the grocery store and started to measure it when mushrooms grow up. It showed some voltage numbers seems promising, and when I changed probe points, the number changed, which gave me an illusion of the relationship between electricity and mushroom sizes. However, it dried out soon in the arid climate, and I can’t get any meaningful measurements anymore. I questioned whether the electricity contained or the conducted material was water rather than mushroom.

Inspired by Shannon, who compared her burning of 48th stairs climbing versus elevator electricity consumption, I am interested in how much energy I have burned in workouts. I usually do three main workouts, some yoga, and relaxing stretching. One of my cardio workouts is riding the Peleton bike, which has energy output on the screen like the picture below. Usually, the instructor pushes you to higher output above 200 Watts, even 400 Watts. It's a large output comparing its adaptor’s 50 Watts. For Pure Barre class, I use numbers estimated from Reddit according to my height and weight, 200 calories for classical and reform class and 250 calories for empower class.
The documentation started Mar 1, and the average usually burns around 900 Calories in a week, which equals 3765 KJ or 1045 Watt-hours. It seems I can power my apartment with my workout if there is no loss in transmission.
