Sodium-ion a candidate for lithium-ion replacement

Regular readers of these pages may remember Professor Donald Sadoway & his ideas on how to create low cost technology, including: “Confine our chemistry to Earth-abundant elements, that’s how to make it cheap.”

Lithium ion batteries violate this principle — at 0.0017% of the Earth’s crust*, lithium is far from Earth-abundant. Further, sources are controlled by just a few players.

Sodium shares many properties with lithium (same column in the Periodic Table, one row down**), but as the sixth most abundant element in the Earth's crust (2.8%)***, it is abundant almost everywhere & so, cheaper. These properties make sodium an attractive candidate for use in a battery to replace existing lithium-ion.

British start-up Faradion, with Williams Advanced Engineering, Oxford University & part-funded by Innovate UK, has developed a sodium-ion battery with performance comparable to lithium-ion.

It’s not just the airline food

Everyone complains about airline food. Not without good reason. But it’s not just the food.

Yes, airline food does suffer the disadvantages which come from being cooked, then transported, stored, & reheated.

But there’s more to it than that. Compared to your typical restaurant, an aircraft cabin at 35,000 feet is at a lower pressure, lower humidity & noisier. All of these factors alter perception of flavours. Sensitivity of the tongue to salt & sweet is reduced, for instance. This does not merely make foods bland, because the ability of the tongue to sense sour & bitter is unaffected.

What we perceive as flavour is largely smell, & this too, is much reduced as the nasal passages dry out due to the low humidity. To overcome the tongue's reduced sensitivity, airlines may use additional salt, which compounds dehydration effects.

Apple Watch not protected by Activation Lock

Activation Lock makes a stolen Apple iOS device useless to a thief. An Apple Watch does not have the same level of protection. An optional password can protect the legitimate owner’s data, but a thief can erase the Watch & then activate it like a new device.

Wearables — steps toward a cyborg future?


Credit: Apple/9To5Mac

New technologies require a new way of thinking. Human beings have to feel their way towards that new way of thinking. At the moment, we are feeling our way towards the ways of thinking required for wearable technology

After using the Apple Watch for a week, Mike Elgan writes in Computerworld that he feels that the Apple Watch may point the way to some significant new ways of interacting with wearable technology.
