Battery of Brussels sprouts
Video of the day | Battery of Brussels sprouts
You’ve probably seen the video in which lemons nourish LED bulb , or where the show clock running on the energy produced potatoes. So, a group of London inventors built a similar device, but using much smaller and less popular product supply. Within Promo exhibition Big Bang UK Young Scientists & Engineers Fair, the design team has created the world’s first battery-based brussels sprouts and connect it to power the Christmas tree lights.
Every year, the exhibition organizers are trying to find new ways to attract children to science and technology. After a little research revealed that the majority of children in the UK would gladly have abandoned the traditional presence on the Christmas table Brussels sprouts, a group of researchers decided to create a battery of cabbage, and helped the company realize its Designworks.
The battery itself consists of five power cells. Each cell is surrounded by 200 kochanchiki Brussels sprouts. In total battery contains nearly 1,000 such kochanchiki. To each of them connected to the copper and zinc electrodes that trigger a chemical reaction between the electrolyte and each kochanchiki, thus creating a small electrical charge. Located in the battery charge this capacitor collects from all kochanchiki and then transmits it to the Christmas tree lights. Furthermore, the battery is located on top of the digital display that indicates in real time how much energy produces currently.
Even when such a large amount of Brussels sprouts, the battery is capable of producing only about 62 volts at a current voltage of 10 mA. But that is enough to power the 100 highly efficient LED lamps arranged on the tree. According to the organizers, cabbage is able to support the production of energy for the Christmas tree for a few weeks, after which it must be replaced with fresh kochanchiki, to nourish the tree was possible for all next Christmas and New Year holidays.
Perhaps this is not the most practical source of energy, but the kids will definitely enjoy what brussels sprouts used as the source of this, and not on their plates.
