○Electricity Generation and Storage [3]

     Assuming a plot size of approximately 12 square meters for a Prout Village dwelling, with batteries of this size, about 1944 units could be accommodated. With each unit storing 25Wh, this would amount to a total storage capacity of 48 kWh. This quantity would weigh around 24 tons, likely more than necessary. However, even a third of these carbon batteries could sustain the daily energy needs of a family of four. It's a practical solution using locally available carbon-based batteries. If bamboo, which grows rapidly and can be harvested multiple times, is used instead of wood for these batteries, it's possible to sustainably produce them. Although burning bamboo initially emits carbon dioxide, the subsequent use of the batteries is semi-permanent.

Power Consumption of Home Appliances (1 kWh = 1000 Wh)

- Microwave: 1500W / Usage for 12 minutes (0.2 hours) = 300Wh.

- Rice Cooker: 1300W / 1 hour usage = 1.3 kWh.

- Hair Dryer: 1200W / Usage for 6 minutes (0.1 hours) = 120Wh.

- Air Conditioner: 660W / 8 hours of daily usage = 5.280 kWh.

- Refrigerator (450L): 250W / 24 hours of daily usage = 6 kWh.

- LCD TV (42 inches): 210W / 5 hours of usage = 1.05 kWh.

- Desktop Computer: 50-150W / 10 hours of usage = 500Wh to 1.5 kWh.

- Laptop: 20-30W / 10 hours of usage = 200Wh to 300Wh.

- LED Light Bulb: 7W / 6 hours of usage = 42Wh.

    Adding household wind power generation supplements electricity when the wind is blowing. Using a vertical-axis wind turbine instead of a propeller-based one ensures adaptability to winds from all directions.

    Making these aspects the basis for home generation and storage, a self-sufficient off-grid system emerges, capable of supplementing power without the need for connecting power lines, proving beneficial during disasters like earthquakes.

    While microbial power generation can occur in various municipal locations to increase power generation, larger power needs prompt consideration of pendulum-style tidal power generation developed by Japanese companies for oceans and rivers.
