Will 2020 (Finally) Be The Year Of Electronic Paper?

These days paper is being phased out whenever possible, and while we’re still far from being a completely digital society, the last decade or two has seen a huge reduction in the amount of paper the average person deals with on a daily basis. At the very least, we seem a lot closer to a future without the printed page than we are flying cars or any of the other concepts we generally associate with the far-flung future.

That said, there’s still something undeniably appealing about reading on paper. The idea of squirting ink on a piece of thin wood might seem increasingly archaic to us, but it sure does look nice when you hold it in your hand. Which is exactly why so much effort has been put into recreating the look of printed paper in electronic form; we all love the experience of paper, but the traditional execution doesn’t align itself particularly well with modern sensibilities.

Of course electronic “eReaders”, most notably the Kindle line from Amazon, have gone a long way towards making this a reality. At least for reading books, anyway. But what about magazines, newspapers, or even the lowly notebook we keep by the bench to jot down measurements or ideas? A PDF datasheet, with graphics where the grey tones matter? Being able to carry a whole bookshelf worth of novels in your bag is incredible, but despite what science fiction has promised us since 2001: A Space Odyssey, we’re still consuming plenty of media off of dead trees.

But that might be changing soon. This year will see the release of two tablets that promise to deliver an experience much closer to reading and writing on traditional paper than anything we’ve seen previously. They certainly aren’t cheap, and it’s too early to tell how much is just hype, but these devices could end up being an important step towards the paperless future we’ve been dreaming of.

COVID-19 And The State Of The Climate

The novel coronavirus sweeping the globe has led governments to institute widespread quarantines to stem the spread. Many industries have slowed production or shutdown entirely, and economic activity has slowed to a crawl. This has naturally led to a sudden reduction in greenhouse gas emissions. But how great will the effect be, and will it buy us any real time?

On The Ground

In the wake of COVID-19, good news stories have sprung up as people look for a silver lining. Unfortunately, these stories aren’t always true. There aren’t dolphins in the waters of Venice, though the water has cleared due to reduced boat activity. And drunken elephants did not begin roaming the mountains of China.

Despite this, there have been notable reductions in emissions in several areas due to government-mandated lockdowns. Northern Italy is seeing a much lower concentration of nitrogen dioxide, likely due to reduced industrial and vehicular activity. Carbon monoxide levels have similarly dropped in New York, while China has seen its carbon emissions temporarily drop by a full 25%.

On the surface of it, these are all promising numbers. Many are cautiously optimistic that this could be a major development to help stave off the worst of climate change for a little longer. Nonetheless, it’s early days yet, and what happens after the crisis passes is just as important as what’s happening now.

No Windshield? No Problem, Says McLaren

All the best sports cars look like they’re moving when they’re just sitting there, and the lines on McLaren’s newest limited-edition plaything redefine that look of speed standing still. Maybe it’s the sneering headlights or the streamlined, reverse-1966 Batmobile styling. Whatever it is, the 804-horsepower two-seater project Elva looks like it’s leaping off the line into the future.

But this future is free from the last thing we’d expect to see removed from any vehicle, especially a $1.7 million supercar — the windshield. Now that the headphone jack has been deemed expendable, it seems that nothing is sacred. The Elva is already a permanent convertible with no windows.

Though McLaren didn’t start this weird and windowless fire, the Elva is meant to fan the flames of futurism. She joins the ranks of a few windshield-free models from Ferrari, Mercedes-Benz, and Aston Martin. In the other guy’s cars, you’ll need a helmet above 30MPH unless you love the thunderous sounds of air buffeting and blown-out hair. It’s a young idea with a few bugs to work out.

What Does A Dependable Open Source Ventilator Look Like?

Ventilators are key in the treating the most dire cases of coronavirus. The exponential growth of infections, and the number of patients in respiratory distress, has outpaced the number of available ventilators. In times of crisis, everyone looks for ways they can help, and one of the ways the hardware community has responded is in work toward a ventilator design that can be rapidly manufactured to meet the need.

The difficult truth is that the complexity of ventilator features needed to treat the sickest patients makes a bootstrapped design incredibly difficult, and I believe impossible to achieve in quantity on this timeline. Still, a well-engineered and clinically approved open source ventilator might deliver many benefits beyond the current crisis. Let’s take a look at some of the efforts we’ve been seeing recently and what it would take to pull together a complete design.

The Real Lessons About 3D Printed Face Shields: Effective Engineering Response In Times Of Crisis

3D printed face shields and other health equipment is big news right now. Not long ago, Prusa Research rapidly designed and manufactured 3D printed face shields and donated them to the Czech Ministry of Health. Their effort is ongoing, and 3D printers cranking out health equipment like the NIH approved design has been peppering headlines ever since.

The Important Part Isn’t 3D Printers

The implied takeaway from all the coverage is that 3D printers are a solution to critical equipment shortages, but the fact that 3D printers are involved isn’t really the important part. We all know printers can make plastic parts, so what should be the real takeaway? The biggest lessons we can learn about Prusa’s ongoing effort are related to how they’ve gone about it.

On 5G And The Fear Of Radiation

The world around us is a scary place, with a lot of visible and invisible dangers. Some of those invisible dangers are pretty obvious, such as that of an electrical shock from exposed wiring. Some are less obvious, for example the dangers of UV radiation to one’s skin and eyes commonly known, but also heavily underestimated by many until it’s too late. In the US alone, skin cancer ends up affecting about one in every five people.

Perhaps ironically, while the danger from something like UV radiation is often underestimated, other types of electromagnetic radiation are heavily overestimated. All too often, the distinction between what is and isn’t considered to be harmful appears to be made purely on basis of whether it is ‘natural’ radiation or not. The Sun is ‘natural’, ergo UV radiation cannot be harmful, but the EM radiation from a microwave or 5G wireless transceiver is human-made, and therefore harmful. This is, of course, backwards.

Rather than dismissing such irrational fears of radiation, let’s have a look at both the science behind radiation and the way humans classify ‘danger’, such as in the case of 5G cell towers. Continue reading “On 5G And The Fear Of Radiation”

Getting To Space Is Even Harder During A Pandemic

At this point, most of us are painfully aware of the restrictions that COVID-19 social distancing protocols have put on our daily lives. Anyone who can is working from home, major events are canceled, non-essential businesses are closed, and travel is either strongly discouraged or prohibited outright. In particularly hard hit areas, life and commerce has nearly ground to a halt with no clear end date in sight.

Naturally, there are far reaching consequences for this shutdown beyond what’s happening on the individual level. Large scale projects are also being slowed or halted entirely, as there’s only so much you can do remotely. That’s especially true when the assembly of hardware is concerned, which has put some industries in a particularly tight spot. One sector that’s really feeling the strain is aerospace. Around the world, space agencies are finding that their best laid plans are suddenly falling apart in the face of COVID-19.

In some cases it’s a minor annoyance, requiring nothing more than some tweaks to procedures. But when the movements of the planets are concerned, a delay of weeks or months changes everything. While things are still changing too rapidly to make an exhaustive list, we already know of a few missions that are being impacted in these uncertain times.
