Ifixit repair kits: everything you need to fix everything

Ifixit produce open repair guides for everything imaginable, in a variety of languages, and help sustain a global community of independent repairers who divert electronics from e-waste dumps and keep poor and marginalized people connected to their work, school and families.

The Ifixit repair kits are thoughtful, high-specification, low-cost toolkits designed to work on all modern gadgets, as well as traditional ones (for example, Ifixit manufacture their own drivers for Apple’s bizarre “pentalobe” screws, which Apple had instructed its Genius Bar staff to quietly swap in during routine repairs).

The big daddy of Ifixit kits is the $130 128-bit Universal Bit Kit, which comes in a handsome wooden case and is covered by Ifixit’s lifetime warranty.

But Ifixit makes smaller, more specialized kits, including theSmartphone Repair Kit, priced at $25, specifically aimed at the budgets of enterprising high-school students who want to start their own smartphone repair businesses, using Ifixit’s manuals.

G20 Governments collectively handed out $452bn in subsidies for fossil fuels in both 2013 and 2014 - four times the amount allocated globally for renewables.

An EPIC View of Earth

“Look again at that dot. That’s here. That’s home. That’s us.” 

Carl Sagan wrote those words in his book Pale Blue Dot: A Vision For The Human Future In Space. His now-famous ode to our home planet (listen to the full passage here, in animated form) is perhaps our most poignant and humble reminder of the exquisite beauty and shared fragility of this planet we call home. 

NASA is now bringing us a daily reminder of that message, thanks to the EPIC camera (a very appropriately named camera, in my opinion) on board NOAA’s DSCOVR satellite. You can see some of its handiwork in the image sequence above.

DSCOVR’s official space job is to observe weather on and around the sun, to extend its mechanical finger into the solar wind and measure how strongly that stream of charged particles is gusting toward Earth. It does this job from a special spot in space called the L1 Lagrange point. If you were to draw a line between us and the sun, DSCOVR would be sitting along it, like so (not to scale):

That’s a convenient place to put a spacecraft, especially one whose job it is to stare at the sun. See, DSCOVR is nestled inside a pocket where it’s tugged equally by the Earth’s and Sun’s gravity, like a stalemate in an orbital game of tug-o-war. Gravity does all the work, and the spacecraft doesn’t need to maneuver much to stay in position. There’s a few of these gravity-neutral Lagrange points out there, as you can tell in the image above, and we’ve got spacecraft residing at all of them. 

As a side effect of its sun-staring mission, DSCOVR’s backside happens to be looking back at Earth full-time. In a way, I think that makes it a different sort of moon. 

NASA doesn’t like to let any opportunity go un-scienced, of course, so they decided to slap a camera on DSCOVR’s rear, the one named EPIC, and use their stable perch to keep a regular eye on us. Good lookin’ out, NASA.

A little change in perspective can do a planet good. In 1990, from a vantage point beyond Pluto, Voyager 1 turned its cameras back toward home to take one last look, giving us the image that inspired Carl Sagan’s ode to ol’ Dotty Blue:

This was not an easy shot to take. Voyager’s camera wasn’t the fancy digital type like most of us have in our phones. It was essentially an old-fashioned black and white tube TV in reverse, relying on colored filters held in front of the camera to highlight different wavelengths of light. Voyager stored its image data on magnetic tape, and each of the shots took more than five hours to reach Earth. Sagan and NASA’s planetary science team had to practically move the heavens (since they were unable to move the Earth) in order to take that picture. 

Now consider the effect this picture has had. That’s home. That’s us. Even if you weren’t born in 1990, everyone and everything that made you is in and on that hazy blue speck. I hope you never lose sight of how amazing it is to view our planet from this perspective. 

Luckily, you can get a reminder every day. The DSCOVR satellite is now sending roughly a picture an hour back to Earth, 24/7/365. That’s a near real-time view of our home. Go take a look. It’s pretty epic.

Could Europe Be Powered by African Solar Energy?

For a long time, people looking for big fixes to climate change have been talking about building huge solar installations in North Africa, which gets a lot more sun than most of the places where solar power is big — Germany, for example. But now, it looks as if someone finally is doing it.

Next month in Ouarzazate, Morocco, the first portion of what eventually will be the world’s biggest concentrated solar power plant – called Noor I – is set to go online, according to the Guardian, a British newspaper.

Eventually, when the entire $10 billion complex, which is being financed with assistance from the World Bank and European Union, is completed in 2020, it will generate 580 megawatts of electricity, enough to provide a big portion of Morocco’s energy needs while still leaving plenty of juice for export. The complex could prevent 700,000 tons of carbon dioxide from being spewed into the atmosphere each year.

The plant uses an ingenious technology for getting the most out of sunlight. A huge array of 500,000 crescent-shaped mirrors focus sunlight and transmit it to a single point on a tower. (The mirrors actually have tiny computers in them, which adjust the angle throughout the day to gather the most energy.)

The plant could turn Morocco, which depends upon fossil fuel imports to fill 94 percent of its energy needs, into a major producer of electricity for export. Find out how by clicking here.

The Scripps CO2 measurements at the Mauna Loa Observatory on the big island of Hawaii have shown that atmospheric carbon dioxide (CO2) levels climbed above the 400 parts per million (ppm). Because CO2 stays in the atmosphere for a very long time, some scientists say for millennia, our global fever has reached the point that no one alive today, and those that follow us, will ever know a world below 400 ppm again.

This week will be the last time anyone alive experiences a CO2 level below 400 ppm. (Saturday Nov 21, 2015)
