In order to welcome the 2020 Tokyo Olympics, the Japanese capital Tokyo has many innovative designs and services, such as the introduction of BRT systems, self-driving car services or the transformation of the village into a hydrogen energy city. Recently, it has announced the need to build solar roads and create an environmentally friendly city. Image.
The new technology will be tested in downtown Tokyo or other regions in the next fiscal year. It is expected that Japan will be in full swing in 2019, and in order to allow the solar panels to withstand the weight of the vehicle, the solar panels will be covered with a special resin to enhance durability. Whether it is a small passenger car or a heavy vehicle, it will not damage the solar panels underneath.
However, it is costly to build a solar road. France has already spent 5 million euros (about 600 million yen) to build a 1-kilometer solar road. The Tokyo government hopes to install it first in areas with large sunlit areas such as state-run parking lots. It plans to use solar energy savings to offset solar construction costs. It is hoped that this technology will be introduced before the Olympics. As more and more solar roads are built, in addition to encouraging the development of solar photovoltaic technology, it is also possible to reduce costs by increasing the amount of equipment.
In May 2018, Green Energy Environmental Protection "7-11 Sagamihara Hashimoto Station 1 Chome Store" in Sagamihara City, Kanagawa Prefecture was opened, and a large number of solar panels were installed on the roof and parking lot. The store manager pointed out that the solar road system can generate 16,145 kWh of electricity per year, which can offset 9% of the power of 7-11; rooftop solar energy can generate 64,608 kWh of electricity per year, meeting 36.6% of the electricity consumption of the store.
Wide range of power generation flooring applications
Tokyo is also considering the introduction of "power-generating floors". As long as pressure is applied, special ceramic equipment generates a voltage, which converts foot vibration directly into electricity. Development company Sound power said that if there is a 60-kilogram passerby on the power generation floor and walks at a speed of two steps per second, the floor can generate an average current of about 2 milliwatts, which can instantly illuminate 300 to 400 LEDs. By installing power-generating floors in building stairs and corridors, in the event of a catastrophic power outage, as long as the local boardwalks, there is light, and large-scale builders and road construction companies have introduced the technology.
According to the Japanese Government's Development Assistance Program (ODA), the power generation floor plan will also be installed in Brazil's streetless walkways and bridges in the summer of 2018. Tokyo is considering using power generation floors for hospitals and exhibition venues. The person in charge pointed out that although the power generation is not high, the technology has a strong energy-saving effect.
