Ride-sharing app Lyft has a new service available in Chicago and San Francisco that they’re calling a “shuttle.” According to Lifehacker, it works like this:
Lyfts can add up fast and Lyft Line, while less expensive, can take you out of your way and make your travel time much longer.
Lyft Shuttle addresses both those issues by having you walk to a nearby pick up spot, get in a shared car that follows a pre-designated route, and drops you (and everyone else) off at the same stop. So, basically, you share a ride with other people (most of the time) so your ride price is lower, but you know exactly how long the ride will take because you’re on a pre-designated route.
There are a number of suggestive parallels between [Elon] Musk and the Wrights, beyond the obvious ones to do with an interest in flight. The [Wright brothers’ father] had very high standards and set no limits on the intellectual curiosity he encouraged in his children; Musk’s father had the same standards and the same insistence on no limits, but was (is) a tortured and difficult presence, ‘good at making life miserable’, in Musk’s words: ‘He can take any situation no matter how good it is and make it bad.’ The Wrights were poorish, the Musks affluentish, but both grew up with an emphasis on learning things first-hand. ‘It is remarkable how many different things you can get to explode,’ Musk says about his childhood experiments. ‘I’m lucky I have all my fingers.’ One very odd thing is a parallel to do with bullies: Musk was set on and beaten half to death by a gang of thugs at his school in Johannesburg; Wilbur Wright was attacked so badly at the age of 18 – beaten with a hockey stick – that he took years to recover from his injuries and missed a college education as a result. His assailant, Oliver Crook Haugh, went on to become a notorious serial killer. Something about these very bright young men set off the bullies’ hatred for difference.
The first battery, a pile of copper and zinc discs, was invented more than 200 years ago, ushering in the electric age. Subsequent versions led to portable electronics, mobile computing, and our current love affair with smartphones (1,000 of which are shipped every 22 seconds). Now batteries are powering electric cars and storing electricity produced by solar cells and windmills, but they don’t last long enough and are too expensive for either use to really go mainstream. To cut the cost, Tesla plans to double the world’s production capacity of the popular lithium-ion battery with its forthcoming $5 billion battery manufacturing plant in the Nevada desert. Tesla’s idea is to use economies of scale to lower prices. Meanwhile, other companies and many industrialized countries, including China and the U.S., are racing to develop batteries that are more advanced than Tesla’s. They’re betting billions that breakthrough battery technologies will help create new industries, juice existing ones, and wean us off fossil fuels because we’ll be able to use the sun and wind in their place. Here is a book, a documentary, and five stories on our battery-powered future.Read more…
Cabin fever might set in quickly on Mars, and it might be contagious. Quarters would be tight. Governments would be fragile. Reinforcements would be seven months away. Colonies might descend into civil war, anarchy or even cannibalism, given the potential for scarcity. US colonies from Roanoke to Jamestown suffered similar social breakdowns, in environments that were Edenic by comparison. Some individuals might be able to endure these conditions for decades, or longer, but Musk told me he would need a million people to form a sustainable, genetically diverse civilisation.
‘Even at a million, you’re really assuming an incredible amount of productivity per person, because you would need to recreate the entire industrial base on Mars,’ he said. ‘You would need to mine and refine all of these different materials, in a much more difficult environment than Earth. There would be no trees growing. There would be no oxygen or nitrogen that are just there. No oil.’
I asked Musk how quickly a Mars colony could grow to a million people. ‘Excluding organic growth, if you could take 100 people at a time, you would need 10,000 trips to get to a million people,’ he said. ‘But you would also need a lot of cargo to support those people. In fact, your cargo to person ratio is going to be quite high. It would probably be 10 cargo trips for every human trip, so more like 100,000 trips. And we’re talking 100,000 trips of a giant spaceship.’
