ABC Energy

1. Summary

Green energy is best, but it needs quite a time to be an alternative to current fossil and atomic energies. The principle of ABC energy is to utilize green energy sources as much as possible, but to prepare fossil energy sources as well. In this specification, we describe how to utilize winds and solars etc. in the ABC Pilot City, which is assumed to be built at Jejudo, South Korea, in 2025. But, before proceeding, let's review the principles of ABC in regard to energy.

1. Autonomization - Not necessary is better than shortage.

2. Optimization - Find out the optimal way to achieve goals with minimum energy consumptions.

3. Green - Use green sources whenever possible.

1. Autonomization

There are many traffics to visit banks, markets, city halls, tax offices, courts etc. By making those facilities and organizations unmanned or autonomous, it's not necessary for citizens to visit there and to consume energies.

ABC is to automate all kinds of human organizations.

2. Optimization

If ABC can't convert current organizations and business autonomous, then it optimize the business processes of them. For example, when you order a pizza, there moves a bicycle or car and a delivery man/woman with the ordered pizza box. If the city you live in has equipped with logistics tunnel and autonomous delivery robot vehicles, only the pizza box or the autonomous vehicles are necessary to move. It consumes less than one tenth of energy required before.

3. Green

By autonomization and optimization, the energy consumption can be reduced to one tenth of current ones. The rest one tenth is to be acquired via green sources.

Those are the principles of ABC in regard to energy production and consumption.

2. Greens

Let's assume there are 200,000 residents in the city with a few manufacturing facilities. So, the city needs energy to satisfy the living and the production of the city.

1. Winds

The mechanism of all kinds of turbines are the same: convert kinetic energy to electricity. Our goal is to design optimal wind turbine, for example, superconducting turbines.

2. Solar

Though transparent solar cells are optimal to applied to current windows, the efficiency of them are quite low: one fifteenth to ordinary ones. Our suggestion is to build solar roofs on roads.

Ordinary, solar roofs on roads are not appropriate due to some reasons below.

• High cost of supporting structure.

• Maintenance

• Theft.

• Accidents.

• Grid Connectivity

But, in the city, all those problems are not relevant. First of all, all cars in the city are driving autonomously without accident.

3. Waterway under the sea

There are many waterways under the sea around the Jejudo island, and these places are optimal for generating hydrogen from water. Our goal is to design a hydrogen plant in the form of a drilling rig which floats on the waterway, gain kinetic energy from waterway under the sea, and use it to produce hydrogen.

3. Livings

About 27% of energy is consumed in households[source]. Because the city automate all kinds of organizations such as traffics, banks, city halls and markets, household energy consumption will be more than 50%. Main usages are for heating, cooling and food.

• The city provides three meals a day, so there is no energy consumption related to household cooking.

Our goal is to design a wind turbine for households' heating and cooling.

• When air is compressed, it heats due to increased friction among air particles. Rub your palms to see what happens.

• When compressed air expands, it cools due to it absorbs energy around it.

Our theory is simple. Use wind turbines to compress air, to utilize the heat from air compressors, and to cool down room temperature by letting the compressed air to expand. See how wind turbine compress air and how air compressor works.

By using wind turbines, we can get both hot and cold water to heat or cool down room temperatures.

4. Energy Grid

Now coding time. The ABC Energy monitors how much energy is produced in the forms of electricity, hydrogen, and heat etc. It also monitors how much energy is consumed by each citizen, house, facility, device, machine and so on.
