The mining giant BPH Billiton, has begun using special caps to log the brainwaves of sleepy drivers to monitor signs of drifting to sleep.

These drivers are operating 400-tonne vehicles at a copper mine in Chile, and so far 1,500 workers have been tested in 150 trucks.

The brainwaves are tested through a six-inch strip is fitted inside the helmet of employees.

“It sits on your forehead and it actually can measure your brainwaves and look at… patterns that show fatigue over time,” stated the Technology Officer of BHP, Diane Jurgens.

“That sensor then talks to a little unit that we install in the cab of a truck and when it detects fatigue, it will notify our drivers but also, just as importantly, it's integrated with our back office and the supervisors that can also get notified so they can intervene.”

Prior to these devices, the company were using sensors that were installed on to a truck’s cab that would detected when a driver’s eyes closed.

“You can't fool this cap because it's watching your brain waves, not looking at your eyes. And so it's a much better technology,” Ms Jurgen added.

The company noted from a Mckinsey study that the global resources industry could save between US4290bn and $390bn a year through utilising new technologies.

Battery-powered future depends on a few crucial metals

Meeting the rising demand for lithium-ion batteries depends on lithium, cobalt and nickel production...

In the big, exciting future that’s measured in kilowatt- and gigawatt-hours, batteries are enabling mass electrification across many sectors. The rapid decline in battery prices has ensured burgeoning interest from electric-vehicle makers and consumer-electronics manufacturers- even from the energy industry, for enormous stationary storage systems operating on the power grid.

Companies such as QuantumScape Corp. are developing next-generation batteries that could accelerate the transition. The field is so competitive that the industry is shrouded in secrecy, but the market still values the company at more than $16bn despite no promise of real revenue for many years to come.

It will be years before any battery breakthroughs reach the mass market. But it’s already virtually certain that rising demand for existing lithium-ion batteries will be exponential and can be matched by manufacturers only if the materials used to make batteries - primarily lithium, cobalt , and nickel - are also supplied adequately. These curves will become steeper in the decade ahead. Take a look at the charts below that show where things are headed.

Batteries

Electrification has become a key theme for automakers in the US and Europe. While it was barely mentioned a decade ago, company executives are increasingly talking up batteries and electric vehicles to investors.

undefined

Lithium

The rapid decline of battery costs over the past decade has surprised even the most optimistic analysts. That has played a crucial role in opening up new markets for batteries to find applications.

undefined

Electric Vehicles

Electric cars will be the biggest force behind the boom in demand for batteries this decade. But batteries will also increasingly be used for smaller vehicles like scooters, commercial vehicles and to store electricity from the grid.

undefined

Investment

The decline in battery prices have helped grow the investment case for storing electricity. Companies and financial firms are now investing over $100 billion a year on energy storage and the electrification of transportation.

Energy

All the energy stored in a growing number of batteries will require a significant increase in a few key metals, lithium, cobalt and nickel.
