The rising sun

Day by day, the world's population rises. The World Energy Council has cautioned that due to population growth, energy consumption would peak in 2030 and double by 2060. As a result, researchers today are looking to future techniques of electricity generation employing a number of various materials and technologies. 1. Coffee Power When coffee cherries are processed into the finished product, an estimated 12.5 million tonnes of coffee are produced worldwide each year as liquid waste. Wastewater from the processing of coffee is a typical by-product that is used to wash coffee beans and make instant coffee. The Surrey University team has created a method to clean up wastewater while also producing electricity. While coffee waste has previously been compressed and sold as "biologs" to be burned, it is believed that this operation is the first to produce electricity from such garbage. The microbial fuel cells can be built of Perspex and stainless steel and are about the siz...

  You may see individuals addicted to their cellphones scanning through social media, Whatsapp, Twitter, and other online digital platforms everywhere since technology has made life easier for us. However, children are particularly at risk from cell phones, and if we don't act quickly, these technological marvels will completely destroy their lives.  Children using mobile phones may pose the following health risks:  1) An international study has identified that children who use smart phones more frequently run the risk of developing non-malignant brain and ear tumours because these devices produce radio frequency radiation that links them to cell towers that offer coverage. This electromagnetic radiation includes other types of radiation that come from using mobile phones, such as heat and microwaves. The radio-waves from our mobile devices are transmitted directly to our brains when we hold them close to our ears. This significantly affects our general health. Childr...
