I think it's been quite a year in the science and technology world this year. Starting with man of the moment Elon Musk, he got his Tesla Model 3 production up and running so they made a profit. https://cleantechnica.com/2018/12/30/2018-was-a-giant-awesome-year-for-tesla-because-elon-musk/ This did not go unnoticed in the transportation world and it seems just about every company involved with transportation has finally taken electrification of the drive train seriously. From all the car companies to the operators of the largest shipping containers, every company has this year put into action a plan to convert to using electricity and storage over petroleum based power for turning wheels and doing heavy lifting. With many of the first generation hitting the market within the next two years. Tesla Semi truck has been seen doing test runs between Tesla factories, possibly carrying batteries from the mega plant to the production lines. Not officially launched yet but I think it will be a big seller next year, depending on how many they can make. Space X not done too bad either with another solid 21 launches, the unforgettable Falcon Heavy launch with Elon's red Tesla and more news about how the Starships that will go to Mars might look like. The Boring Company got it's first test tunnel built and Elon even built a raft to save some boys trapped in a cave, even if that one did not end well. He also offend the regulators with a joke about stock prices. But all in all a good year for him and his business. Rocket Lab had a good year too getting it's launch business off the ground. Their aim to make 3D printed rockets that can quickly and cheaply get you into space offers a distinct advantage over the likes of SpaceX where you may have to wait a long time for a lunch window. Virgin Galactic got back in the air too and did a test flight into the very base of what we call space. Though I think their long term mission is to offer flights half way round the would in 20 minutes bouncing off the edge of space, more than frighting stuff into space. So height is not important as getting from A to B as quick as possible, using traditional runways too. Blue Origin completed a lot of testing too. So all the pieces are in place for an exciting space filled future. While on the space subject it's been quite a good year there too. With China going to the dark side of the moon but ditched it's space station. Many vising asteroids and other rocks floating round the sun including the JAXA Hayabusa2 and Nasa's Osiris-Rex. That object Oumuamua which flew through from outside our system. Nasa has a new lander on Mars, Parker Solar Probe but unfortunately it's new space telescope is starting to look like a white elephant.
