On today’s show, we’ll explore some useful devices that make use of solar energy to perform a variety of functions in daily life. The Sun constantly radiates its loving energy into the cosmos, and nowadays, technological advances are allowing us to make use of its energy to operate a wide array of practical gadgets. For example, solar panels covert sunlight into electricity by means of photovoltaic cells, and photoelectrochemical cells use artificial photosynthesis to convert sunlight into solar energy. Many small devices or tools powered by the Sun have also emerged on the market, making this

That plastic bottle you just used will be around for at least another four hundred years. In fact, almost every piece of plastic we’ve ever made is still here with us somewhere. Scientists have calculated that around twelve million tons of plastic is added to our ocean every year. These pieces of floating plastic get eaten by turtles, whales, dolphins, seals, sea birds and other marine animals where they block up their stomachs.And there’s another problem. Sunlight and waves cause the big chunks of plastic to get broken down into smaller pieces called microplastics. These tiny bits of plastic
