Which of course always bugged me. Not just because of what I know of biology, but the second sentence. "Combined with a form of fusion". The thing we understand to eventually provide abundant clean unlimited electricity (okay, relatively speaking). It's a bit like saying "The human trigger finger can exert 300 pounds per square inch of force, and perform over 500,000 foot-pounds of work. Combined with a standard-issu…

From a physics point of view it is complete bull-shit.

The original script had machines using human brains for their computing power but the execs thought that would be too complicated for people to understand.

How would that script have ended? With humans required for computing power there's no way the machines give up their existence to release the humans.

At least I can imagine them using alternate power sources with collaboration for the humans. Cleaning the sky for example.

If we're talking about low-power mcu, here's something that might interest the the hacker community:

A new API,to be released in april, that enables programming mcu's to very low power,easily(versus very high complexity of currently needed to achieve low power). It uses the mbed, which is of similar complexity to the arduino:

TIL. That one concept if carried through the movies changes a lot.

The chip is so low power that it can be powered off energy capture from the body, as Andreas Eieland, Atmel's Director of Product Marketing for low-power products, demonstrated at CES earlier this year. The human body generates more bio-electricity than a 120v battery, and over 25,000 BTUs of body heat. Combined with the Atmel SAM L21 32-bit ARM MCU, the machines had found... all the energy they would ever need.

That quote is so totally non-scientific. For movies to get basic physics so terribly wrong is very sloppy.

Sometimes I feel like I'm the only person who isn't terribly bothered by sloppy science in movies. I prefer movies that are entertaining or thought-provoking, not factual.

Besides, the Matrix is about how our world is a simulation - who's to say how physics works in their "real" world?

I'm trying to figure out if you're joking or not. BTU = British Thermal Unit and is pretty much the standard measure used around the world when talking about energy use associated with heating. It's the amount of energy needed to heat one pound of water by one degree Fahrenheit, regardless of where you find yourself in the world...

As an additional data point, BTU isn't used in Britain very much these days. As with germany, kilowatt-hour is the preferred unit of (heating) energy.

Um, I should have elaborated in my original post - it most definitely is still heavily used in the UK by, for example, architects when evaluating how much heating a house will need. My original post wasn't terribly clear about that, my bad... Yes, consumer-facing information these days is indeed more likely to be expressed in kilowatt-hours...

Still waiting for clockless chips here...

Been done - on ARM instruction sets, no less. http://en.wikipedia.org/wiki/AMULET_microprocessor

Also on Forth instruction sets:

meanwhile the latest and greatest 2015 device is an all-day wristwatch the weight of a pack of cards [1] (for the smaller Apple watch [2]) that in Apple's own "watch test" tells time for up to 48 days before dying --- whoops, no, I meant 48 hours [3] :

>Testing conducted by Apple in March 2015 using preproduction Apple Watch and software paired with an iPhone using preproduction software with 5 time checks (4 seconds each) per hour.

This is as compared with simple mechanical wristwatches that are self-charging (through wrist movement) and can be worn indefinitely, or have 72-100 hour power reserves from winding. [4] This is mechanical power we're talking about.

So don't talk to me about decades until you can get more than 48 hours of battery life....from a watch.

Sure, the Apple watch is fairly likely to be a ridiculous geegaw.

It's also going to do a lot more than the mechanical watches you are comparing it to.

If you just want to tell time, there is a wide market of solar watches:

The Seiko tech runs for 6 months with no charging (left in total darkness).
