No one can accuse Andrew Forrest of lacking ambition. The billionaire entrepreneur made a fortune by dismantling the West Australian iron ore duopoly of mining powerhouse BHP Group and Rio Tinto – something skeptics say can’t be done. He now wants to make another fortune by helping save the planet and turning the mining company he controls — Fortescue Metals Group — into a global leader in renewable energy, and green hydrogen in particular. During a recent visit to London for the FT Hydrogen Summit, Australia discussed its plans for FMG, denounced companies promoting blue hydrogen, and questioned Tesla’s Elon Musk’s green credentials. Forrest reckons his green energy unit, Fortescue Future Industries, could go from a standing start to producing 15 million tonnes of green hydrogen per year by 2030 — just 5 million tonnes less than the goal set by the European Commission over the same period. Elon Musk knows that almost every time a Tesla is plugged into almost every grid in the world, i

Octa-glove takes an underwater Virginia Tech playing card from Michael Bartlett’s lab.

We use tanks to breathe, neoprene clothing to protect and warm us, and glasses to see clearly. In such an environment, human hands are also not well equipped to hold things.

A research team led by Michael Bartlett of Virginia Tech has developed an octopus-inspired glove that can safely grip objects underwater. Their research was selected for the cover of Science Advances on July 13. Humans are not naturally equipped to thrive in an underwater environment. We use tanks to breathe, neoprene clothing to protect and warm us, and glasses to see clearly. In such an environment, human hands are also not well equipped to hold things. Anyone who has tried to hold a wriggling fish will testify that underwater objects are difficult to grip with our land-dwelling fingers. “There are critical moments when this becomes mandatory,” said Bartlett, an assistant professor in the department of mechanical engineering. “Nature already has some great solutions, so our team looks to the natural world for ideas. Octopus being the obvious choice for inspiration.” Rescue divers, underwater archaeologists, bridge engineers, and rescue crews all use their hands to get people an
