This custom 3D-printed bicycle helmet is the future of saving skulls

  • After five years of research, Cook discovered that hexagonal cells performed far better under impact load than EPS foam when surrounding spherical objects, like your head.
  • In the case of helmets, manufacturers also need to cater for a range of sizes to fit varying head shapes, which would require more research, time, tooling, and testing to produce a workable product.
  • Throughout HEXRs development, the company tested various materials, manufacturing techniques, cell sizes, and layouts, but it was always based around 3D printing.
  • Eventually HEXR settled on a form of additive manufacturing which involves using heat, lasers, and polymer powder to sinter together and effectively “print” the helmet.
  • After hundreds of prototypes, and thousands of tests (over 3,200 in fact) HEXR found that a solid bioplastic polymer, called Polyamide 11, handles crash forces best and is easy to use in additive manufacturing.

Health impacts of climate change on children don't need exaggerating

  • The 2019 report of the Lancet Countdown on health and climate change, put together by doctors and researchers, warns that children are particularly vulnerable to climate change, because a warming world exposes them to more infectious diseases, malnutrition and stunted growth, and dirty air that hinders the development of their lungs.
  • Elizabeth Robinson at the University of Reading, UK, one of the report’s authors, says children’s diets are also at risk, with under nutrition and malnutrition set to rise as climate change causes food production to fall.
  • Watts says the current trajectory of global carbon emissions means that we are on track for more warming than the worst case scenario – of a 2.8-4.6°C rise by between 2080 and 2100 – so 4°C is a conservative estimate of what a person born today might experience.

One company is tackling hotel waste by collecting and cleaning half-used soaps

  • Yet things could soon change, as many of the nonprofit's major hotel partners are ditching the single-use toiletries and looking for more sustainable alternatives for their bottled liquid soap and shampoo.
  • Narrator: The nonprofit will still recycle bar soaps from IHG, since the hotels will continue to offer them.
  • COO Americas for IHG, Colleen Keating: We'll still have the opportunity to donate our soap to organizations like Clean the World.
  • We're going to put it into our system so we can provide impact statements back to each one of our 8,000 hotel partners, so they know exactly how much landfill diversion they've had, how many bars of soap I've gotten into the hands of children and mothers around the world because of their efforts, how much plastic has been recycled.

Like Y Combinator, but for Hollywood Scripts

  • Imagine Impact uses machine learning to sift through applications for its screenwriter boot camp and identify new voices.
  • This year, the program received more than 4,000 submissions for just 21 spots in its third class.
  • The Impact application consists of 70 questions, what Mitchell describes as a “thesis-like defense” of why the writer’s particular project deserves investment.
  • To manage the overwhelming volume, Impact uses machine learning to sift through the giant pool of applications and identify new voices.
  • The AI is part device, part catalyst: The technology searches for diverse applicants–Mitchell explains they look for people who have overcome challenges in their careers or lives–with the goal of shaking up the historically homogenous film industry.

DRIVING THE FUTURE: How the transportation industry is evolving to help save the environment

  • The transportation industry produces the largest share of greenhouse-gas emissions in the United States.
  • Data published by the US Environmental Protection Agency (EPA) in 2017 show that the sector's fossil fuel-burning vehicles: automobiles, planes, trains, and ships, are the primary culprits.
  • Collectively, they accounted for about 29% of greenhouse-gas emissions in the states.
  • And the fuels that most of these conveyances burn are petroleum-based, which negatively impact the environment on various levels, from production to delivery to consumption.
  • To its credit, the industry is aware of its outsize impact on the environment and it is making efforts, with varying degrees of success, to change its polluting ways, but there is much work to do.
  • Here, we'll discuss how tech giants are simultaneously reshaping mobility and shipping, why the world's largest economy could get left behind in the global shift toward electric vehicles, how the aviation business is negotiating the colossal task of cleaning up its act, and more.
