and programmes like springwatch, an annual tv show that watches british wildlife during the changinginsight into these animals' lives. the thing is, for programmes like springwatch to run, it requires a lot of time, effort and equipment. with over 60 crew and 35 cameras, it is one of the biggest outside broadcasts that the bbc offers. so it needs a lot of power. but in an effort to be more green and protect the wildlife they feature, springwatch has taken a number of measures to cut down their emissions. and we turned up to one of their production bases to see what they are. now, this is the big one — the green hydrogen generator. why is it called green hydrogen? because the process of electrolysis used to separate the hydrogen from water is powered by solar energy. if it was powered by fossil fuels, then it would be known as blue or black hydrogen. not so good — it kind of defeats the purpose. but with solar, you are using clean energy to make clean energy. compared to a diesel generator, it is a 3.5—tonne reduction based on what we normally do with a couple of weeks use. a couple o

change is never convenient or easy, but the team here at springwatch are taking strides forward to helpng when it comes to powering our devices, this is a sign of things to come. omar there in norfolk. meanwhile at manchester's science and industry museum, 100 years of the bbc is being celebrated with a exhibit featuring broadcast artefacts, plus a few more recent additions. this funky looking box was a prototype which was an early part of the bbc�*s research and development project for storing your data yourself, so the idea was that the device would keep track of what you are listening to and watching, but that data was just yours, unless you chose for it not to be. it was inspired by a new vision that said tim berners—lee had for the web to rethink the ownership of our data. back in 2018, he told us about what he calls a midcourse correction for the internet, an idea called solid.— for the internet, an idea called solid. . ., ., called solid. imagine a world where before _ called solid. imagine a world where before you _ called solid. imagine a world where before you use - called sol
