Nothing to fret about, but it is interesting that our Earth and Moon may end up colliding in the end. That’s long after our Sun has expanded as a Red Giant, but the implications for other earth-moon type systems are interesting.

For now, our anomalously large Moon is spinning away from us at a variable rate of 3.8 centimeters per year. But, in fact, the Earth and Moon may be on a very long-term collision course — one that incredibly some 65 billion years from now, could result in a catastrophic lunar inspiral.

“The final end-state of tidal evolution in the Earth-Moon system will indeed be the inspiral of the Moon and its subsequent collision and accretion onto Earth,” Jason Barnes, a planetary scientist at the University of Idaho, told me.

We can’t be sure, yet, though, whether or not the Earth-Moon system would survive the Sun’s Red Giant Phase, says Barnes. That is, when some six billion years from now our Sun runs out of nuclear fuel; its core becomes a burned-out remnant white dwarf; and, its outer layers expand outward beyond Earth orbit.

China’s Chang’e lunar probe dynasty is already having a great year. The Chang’e 3 lunar lander surpassed all expectations last week to emerge from its 14th hibernation while the Chang’e 5-T1 just completed its transfer from the Earth-Moon Lagrange Point 2 into a stable orbit around the Moon. Chang’e 3’s main mission was only to take spectrographic and ground penetrating radar measurements, but the Chang’e 5 missions will bring back the first samples containing the actual prize — fusion-ready helium-3.

One of the main reasons helium-3 is sought as a fusion fuel is because there are no neutrons generated as a reaction product. The protons that do get generated have charge, and can therefore be safely contained using electromagnetic fields. Early dreamers imagined that Saturn or Jupiter would be the ideal places to try and get their hands on some helium-3, but it now appears that the Chinese have set their sights on the Moon.

In Brief

  • By applying 4.95 million atmospheres of pressure to liquid hydrogen, Harvard physicists have claimed they were able to make it metallic, a state of hydrogen that had never existed on Earth before.
  • Physicists predict that metallic hydrogen is an authentic superconductor, so if stabilized, it could revolutionize everything from energy storage to rocketry.

As reported back in September, two studies, each with a different approach, were attempting to created metallic hydrogen, and now, more than 80 years after it was predicted to be possible, the Harvard University team has finally managed to produce the elusive state. Physicists Isaac Silvera, who has been working on this problem for 45 years, and Ranga Dias published their study’s results this week in the journal Science.

To develop metallic hydrogen, Silvera’s team squeezed two opposing heavy-duty diamonds together to compress gaseous hydrogen, and then they transitioned it into its liquid state by lowering the temperature [hydrogen liquifies at a temperature of −252°C (−423°F)]. They then gradually increased the applied pressure on the solid hydrogen by twisting a steel screw to exert force on the diamond anvil. It was then that changes were noticed.

On Wed we saw Tata’s new hydrogen bus; and now this.

DETROIT (Reuters) — General Motors Co and Honda Motor Co are expected on Monday to announce an expansion of their collaboration on fuel cell technology development, people familiar with the plans said following a notice of a press conference.

GM and Honda on Friday said two senior executives would hold a news conference in Detroit with Michigan’s Lieutenant Governor, Brian Calley.

Mark Reuss, GM’s executive vice president for global product development and Toshiaki Mikoshiba, chief operating officer for Honda’s North American region, are scheduled to make “an important advanced technology announcement,” the companies said. The statement did not elaborate.

If you’re not paying attention to what’s going on in energy, you should. We’ve seen this movie before. Spoiler alert: There’s massive economic opportunity ahead. How massive? Imagine standing in 1992, knowing that Google, Akamai, Netflix, Facebook, Amazon, eBay, BuzzFeed and Uber lay ahead.

This time it’s the “enernet,” not the internet, that will transform our lives. The story is the same, though the players have changed.

Here’s the tee up. Across the country, incumbent network providers operate highly centralized networks in their respective cities. Then, scrappy local outfits start serving the market with innovative, distributed technology. These startups create competition, and a new network emerges atop the legacy network.

Research by scientists at Swansea University is helping to meet the challenge of incorporating nanoscale structures into future semiconductor devices that will create new technologies and impact on all aspects of everyday life.

Dr Alex Lord and Professor Steve Wilks from the Centre for Nanohealth led the collaborative research published in Nano Letters. The research team looked at ways to engineer electrical contact technology on minute scales with simple and effective modifications to nanowires that can be used to develop enhanced devices based on the nanomaterials. Well-defined electrical contacts are essential for any electrical circuit and electronic device because they control the flow of electricity that is fundamental to the operational capability.

Everyday materials that are being scaled down to the size of nanometres (one million times smaller than a millimetre on a standard ruler) by scientists on a global scale are seen as the future of electronic devices. The scientific and engineering advances are leading to new technologies such as energy producing clothing to power our personal gadgets and sensors to monitor our health and the surrounding environment.

Sounds pretty neat, eh? Wouldn’t it be nice never to have to worry about running out of fuel or charge ever again? And also to not have to pay for it would be even better! Well, that is potentially what is about to happen over in Israel right now as testing continues into electric roads that can wirelessly charge electric vehicles as they’re moving along.
