The point of this graph is to show that a human being on a bicycle is a more energy efficient way of getting around than the way (some/most) other animals do. I like that.
But a human by itself is quite energy efficient too, according to the graph. We evolved for walking and running long distances, so no surprise. But maybe not so nice that an airliner comes out pretty well too.
This was last year. This year is on track for becoming much worse.

I only know popular science / scifi, but I like the tube idea. If you throw away one end of the tube really fast, like the speed of light, the tube will automatically get longer, probably allowing you to hold on to the other end comfortably. The examples in popular science usually involve ladders instead of tubes, but it may be transferable. Then, if you throw it even faster like over the speed of light (there are some people that say this is impossible, the trick is to ignore them), it will break the limit of causality and any messages you shout into one end should be encountered by you before you shouted them. Maybe with some weird Dopler effect. And maybe I'm wrong...
Removable and replaceable portable batteries in consumer electronics by 2027
Hopefully this will force the smartphone companies to make their batteries replaceable again and reduce some e-waste this way.

Amazing! Things are so funny when they're true, as in this is exactly how fossil fuel enthusiasts think (as well as other addictions like smoking)

I really like this film. I keep changing what I would mention as my favourite film (I have a list) but a long time ago the subject of favourite film came up at work and a colleague of mine and me at the same time said Bridge to Terabithia. Which is such an odd thing to happen, as it's not even that that many people have even heard of this film...
I'd say this film isn't that much underrated, as just not rated because it is quite unknown.
Anyway, AnnaSophia Robb is brilliant.

I think these magic eye pictures may be some kind of conspiracy, 'The Emperor's New Clothes'-style, where a few people only pretend to 'see it'. Though if you're following WelshPixie you already know what it's going to say...
Cross your eyes they say... What if your eyes are already crossed? Instructions on such pictures say to 'start with your nose touching the image where the picture should be blurry', so I guess my nose is too long or my nearsightedness too strong...
Content warning for those without stereo vision: we can't see this so don't waste your time.
This reminds me of a recent episode of Who Do You Think You Are, the British celebrity genealogy series that I think are actually history documentaires by stealth. One of the ancestors of the celebrity had been involved in British tank engineering in the second world war. They had wondered why this ancestor had a trunk full of photos of damaged and shot-up British tanks in his attic. Turns out he was part of the retreat to/at/from Dunkirk and had used the opportunity to photograph the failed tanks, so back in Britain they could study what had gone wrong and learn from it.
Just had a very quick look at cohost and these are my very initial impressions:
+ the vibe is very tumblr, in lots of ways
- things are even more difficult to find than here, and/or it is even emptier
It looks like especially 'artists-from-tumblr' should be able to find their place there.
I spent so long trying to get these photos downloaded from my camera. It insisted on first downloading the 600 earlier ones and ran out of battery twice.
