  • UK government invests £60 million in Skylon 'super-plane' that could cut London to Sydney flights to just four hours
  • Its 'Sabre' engine - a hybrid rocket and jet propulsion system which theoretically allows travel anywhere on Earth in four hours or less - could become a reality in a decade.
  • A full ground-based engine test is currently planned for 2020.

  • The super-plane will rely on cooling an incoming airstream from 1,000 degrees C to minus 150 C almost instantly, at close to 1/100th of a second.

    Aerospace flight research aiming to speed up long-distance flights. However investment volume seems inadequate for such a huge project.

Driverless cars, pilotless planes … will there be jobs left for a human being... - 3 views

  • From staff-free ticket offices to students who can learn online, it seems there is no corner of economic life in which people are not being replaced by machines.
  • One of the reasons Google is investing so much is that whoever owns the communications system for driverless cars will own the 21st century's equivalent of the telephone network or money clearing system: this will be a licence to print money.
  • The only new jobs will be in the design and marketing of the cars, and in writing the computer software that will allow them to navigate their journeys, along with the apps for our mobile phones that will help us to use them better

  • The invention of 3D printing, in which every home or office will be equipped with an in-house printer that can spew out the goods we want – from shoes to pills – anticipates a world of what Summers calls automated "doers". They will do everything for us, eliminating the need for much work.
  • we have come to the end of the great "general purpose technologies" (technologies that transform an entire economy, such as the steam engine, electricity, the car and so on) that changed the world. There are no new transformative technologies to carry us forward, while the old activities are being robotised and automated.
  • The second is in human wellbeing. There will be vast growth in advising, coaching, caring, mentoring, doctoring, nursing, teaching and generally enhancing capabilities.
  • Notwithstanding robotisation and automation, I identify four broad areas in which there will be vast job opportunities.The first is in micro-production
  • The third is in addressing the globe's "wicked issues" . There will be new forms of nutrition and carbon-efficient energy, along with economising with water, to meet the demands of a world population of 9 billion in 2050.
  • And fourthly, digital and big data management will foster whole new industries
  • the truth is, nobody knows. What we do know is that two-thirds of what we consume today was not invented 25 years ago. It will be the same again in a generation's time

    demand for the new expertise may impact not only the school and academic education, but earlier development stages

Looking at supersonic airliners - 0 views

  • The latest new concept design is called Skreemr, which -- if developed -- supposedly would carry 75 passengers from London to New York in 30 minutes
  • unlike rockets, scramjet engines would burn oxygen from the atmosphere instead of having to carry heavy tanks full of oxygen
  • A hybrid rocket and jet engine is being developed by Reaction Engines with joint funding by the UK and BAE Systems, which could one day lead to a new supersonic airliner
  • ...2 more annotations...
  • Aerion is developing a $110 million, 12-passenger business jet capable of hitting Mach 1.6 -- or close to 2,000 kilometers per hour
  • Expected delivery of this new supersonic plane: 2022.

LEGO.com Parents Child Development : Conflict Play - 0 views

  • research shows that even very young children understand the distinction. Kids as young as four or five years old understand that it’s against the rules to turn aggressive play into real aggression.
  • As they grow older, children begin to develop an understanding of good and evil
  • Youngsters between the ages of 6 and 7 can better interpret characters’ emotions and motivations

  • even in the absence of information about the character’s past.
  • The age of 8 has been identified as a watershed at which children become measurably more likely to act out aggressions after watching violent behavior on television
  • . The children recognize that in the real world it’s impossible to fly without a plane or to be born with skin that deflects bullets. 
  • By age 10 or 11, children will make fairly complex judgments about characters’ motivations and they regularly distinguish between justified and unjustified violence
  • One study also found that if you ask children between the ages of eight and ten who they most want to be like, they are far more likely to cite superhero type characters than everyday folks like their parents.
  • but conflict play continues to provide a unique transitional space for children to explore and express their own tensions
  • We also aim to develop conflict play scenarios where children can experience the benefits of cooperation. With the fate of the world (or even the entire universe) hanging in the balance, children must learn how to build teams, trust in others and work together towards common goals. In those pretend situations, developing social skills may be the only way to overcome the lords of evil!

Virgin Galactic Wants to Fly You From LA to Tokyo (Through Space, In One Hour) | Mother... - 0 views

  • When Virgin Galactic finally takes its first tourists to space, it'll just be a a stepping stone to what the company's ultimate mission is: Flying people from one place on Earth to another place on Earth, just like any other airline. Except in this version, you'll travel through space and be able to fly from Los Angeles to Tokyo in an hour.
  • He's discussed creating a supersonic passenger plane himself, but why settle for an incremental change when, if it works, "point-to-point suborbital space transportation" promises to be a complete paradigm shift?
  • Virgin's daring, sometimes insane chairman Richard Branson has long had his eyes on a supersonic commercial airline
  • ...1 more annotation...
  • The Concorde failed for a lot of reasons, not least of which the fact that it was very, very expensive. So far, hundreds of people  have shelled out $250,000 to take a quick suborbital spaceflight with Virgin Galactic, but are they going to be willing to pay hundreds of thousands of dollars to save 12 hours flying halfway around the world?

  • In around two months, the team behind the solar-powered aircraft Solar Impulse 2 will attempt the first ever around-the-world flight powered only by sunlight.
  • After taking off in Abu Dhabi, the Solar Impulse 2 will make stops in Oman, India, Myanmar, China, the US, and Southern Europe or North Africa before landing back in Abu Dhabi sometime in August.
  • The Solar Impulse 2's across-the-world flight should clock 500 hours total flight time and around 21,748 miles
