Flying or driving — which is greener?

At first glance, the answer seems obvious: a 747 uses 1 US gallon (~3.79 litres) of fuel per second — 5 US gallons per mile — 36,000 US gallons (150,000 liters) in a 10 hour flight — case closed. However, there is much more to be considered, including:

• number of passengers — cars typically have only one passenger, whereas a 747 can accommodate up to 660.

• efficiency varies between car & aircraft propulsion method, model & configuration, & even driving style.

Green Car Reports takes a look:

Snoopy at the tennis

"I was dizzy from the middle of the first set & then I saw Snoopy & I thought, 'Wow, Snoopy, that's weird.' I couldn't keep my balance anymore & I leaned over the fence & when I woke up people were all around me." — Canadian professional tennis player Frank Dancevic, after collapsing from heat stress at the 2014 Australian Open

9,500 mAh battery suggests good battery life, but 12.2 inch screen suggests high battery consumption. We'll see.

Zagg has a keyboard case in development. A problem with keyboard cases for existing tablets is that the keyboards are the same width as the tablet & so are less than full size. Cases for these larger tablets will be full size, or at least closer to.

It's not the heat, it's the carbon dioxide

Jumping allows the conch snail to escape from the predatory cone snail. Previous experiments had shown that rising temperature had left the conch's predator avoiding ability unimpaired.

No such luck with rising carbon dioxide levels:

New Corning Gorilla Glass

Mobile phones — so many uses — clock, calculator & SMS were amongst, if not the, first uses, apart from voice. Current smartphones include Web browsing, email, games, GPS navigation, word processing, document scanning & storage, programming environment, photography, photo editing, astronomy & banking in their repertoire.

And the next killer app is:

killing germs?
