With the gradual consumption of the earth's energy, people's awareness of energy conservation and environmental protection has gradually increased. As the most energy-consuming lighting fixtures, it is the focus of energy conservation and emission reduction of local governments. And some underdeveloped regions have not been able to provide a continuous and stable power supply, and even use kerosene lamps. In recent years, some conceptual ideas of human, biological, and thermal power generation have been realized and brought to market. Xiaobian takes you to look at the inventions of environmentally friendly lamps in recent years.
1. Human power generation leads to the view! Street lights can be illuminated for 12 hours
The picture above shows the addition of two “manpower†circuit lights next to the tram station under the Guangzhou Tower. Its designer MattHope called the streetlight "People's Power Station". The passing people only need to exercise for 45 minutes on sports equipment similar to that in residential areas and parks. The gears rotate in the magnetic pole at a speed of 9 laps per second. The electromagnetic field, the kinetic energy generated by the movement will be converted into electric energy and stored in the battery. The street lamp will automatically illuminate under the night light by light induction, enough for 12 hours.
2. LED street lights that use solar energy and pedestrian footsteps to generate electricity
Recently, New York startup EnGoPLANET announced that many sidewalks in the "Sin City" will soon have streetlights that use solar energy and pedestrian footsteps to generate electricity.
EnGoPLANET said that their street lights at Boulder Plaza will not only use solar power, but also the footsteps of past pedestrians to keep these lights on all night. Each time a pedestrian steps on a pedal fitted to a street light, it can generate 7W of power, which is then automatically stored in the battery. Depending on the design, you can also choose 25-75W LED lamps of different powers. In addition, the street light is equipped with sensors that monitor air quality, temperature, humidity and more. At the same time, these street lights will also add free WiFi hotspot function and provide mobile phone charging.
3. Small lamp SALt powered by salt water is environmentally friendly and healthy
It is reported that the SALt salt lamp only needs a glass of water and two spoonfuls of salt, and then can be used after connecting the two electrodes. At present, this salt lamp is still in the development stage of the prototype, and the whole team even envisions that the USB port can be used to power the smartphone through the salt water table lamp. According to the development team's estimate, this kind of desk lamp can be used continuously for about half a year in the case of 8 hours of use per day.
4, mini generator point candle can also generate electricity to create lighting
When you light the candle at the top of the candle, through the thermoelectric conversion device, the top LED lamp will be illuminated by the energy converted by the heat, so that the excess heat of the candle is more fully utilized.
5. LED bulbs that use gravity to generate electricity: less than $5
London-based designers Jim Reeves and MarTIn Reddiford have developed a lighting solution specifically for families in developing countries.
This GravityLight is equipped with several pulleys and a well-designed powertrain. At the same time, it is equipped with a nostalgic weight wheel to generate electricity by gravity. GravityLight's entire power generation process is to refer to the weights to the sky and then convert the power into electricity. It can be slowly lowered, and the energy of illuminating for 30 minutes. Since there is no electricity, the initial investment is almost zero and no garbage is generated.
At the same time, this GravityLight can even charge other devices. Devices that need to be recharged can be connected to one of the interfaces on the GravityLight front panel. It is even possible to adjust the brightness of the GravityLight bulb to suit the user's needs, thus extending the use time. It is reported that the cost of this GravityLight bulb is less than 5 US dollars (about 31 yuan).
