YotaPhone 2 — a phone with 2 screens

Credit: YotaPhone/Indiegogo

Medium to high-end smartphones have brilliant, sharp, colourful screens. Most users place a high value on the quality of the screen. But such brilliance is not without cost: battery consumption & poor visibility in direct sunlight.

In contrast to the screen technologies used in smart phones, there are black-&-white displays which consume much less power, require no backlight & are not compromised by direct sunlight.

popSLATE is a case for the iPhone which contains a monochrome E-Ink screen. E-Ink is superior for specific purposes, such as:
● decorative — protective phone cases often have a decorative image — popSLATE can have one that can be changed as often as desired, & the display only consumes power when it changes
● any other display which is required for an extended period — speaking notes, lists, directions, e-reader — can be displayed without the battery drain of the main screen
● any display which must be viewed in direct sunlight

popSLATE is compromised because, as an add-on, it’s functionality is limited.

YotaPhone released its first dual screen phone last year. Having been designed with the two screens in mind , it made better use of the second screen than an add-on device could hope to do, but was still limited.

As a second generation device, YotaPhone 2 makes all the functions of its Android operating system available on both screens. It's available via Indiegogo:

How much coffee do you drink? How much caffeine?

Caffeine content of coffee is not a standard unit. Variables include:
• instant generally contains less caffeine than fresh
• type of coffee bean
• grinding
• how the coffee was made e.g. filter verses percolated
• where it was made

Where it was made? In 2005, a university study measured the caffeine content of 97 short blacks from restaurants on the Gold Coast, Queensland, Australia. The strongest sample contained nearly nine times as much caffeine as the weakest.

Waste heat can be recovered as relatively green energy

“Pollution is nothing but the resources we are not harvesting. We allow them to disperse because we've been ignorant of their value.” — R. Buckminster Fuller — http://www.brainyquote.com/quotes/quotes/r/rbuckmins101926.html

Not normally considered a “pollutant”, but data centres spend a great deal of money on infrastructure, energy & other running costs to remove the heat produced by servers. In accordance with the advice of Buckminster Fuller, above, heat in data centres is coming to be seen as a resource:

A startup in the Netherlands has plans to move servers to homes for heating:

Dumbing down Australia — the view from Bloomberg

“Having this reliance on the bottom end of the economy, like small businesses, is a short-term fix,” said Andrew Hughes, a lecturer at the College of Business and Economics at Australian National University. “Cutting back on research is insanity.”
