I am a skilled heavy goods mechanic, qualified to teach in further education. But what is the point of teaching about fossil fuels and engines when i have seen technology that makes it all redundant! The craft we have witnessed are powered by electro-magnetic means. No need of fossil fuels and no damage to our atmosphere. No need of roads, ships, planes or trains. There are a lot of large companies affected perhaps that is the reason we are being denied this technology.
