Orlando announces first vertiport for air taxis

Here they come, ready or not: Get used to the words “vertiport” and “air taxi,” because it’s happening faster than many thought. The FAA Re-Authorization Act, signed into law in October 2018 included five provisos we welcomed that address the airport and aircraft noise issue. But the same Act also approved what aircraft futurists wanted: accelerated development of both drone deliveries–backed by Amazon and Google–and what we used to call “AirUber,” i.e., mostly electrically-powered, small, vertical-takeoff air taxis known technically as  electric vertical take off and landing vehicles, or eVOTLs. In the end, aircraft may get quieter, but there are going to be lot more of them buzzing around.

Andrew J. Hawkins, writing in The Verge, describes a deal between the Orlando city council and the richly funded German start-up company Lilium, which has launched and begun testing its 5-passenger eVOTL. Clearly, there’s a long way to go, and as Hawkins points out there are at least 100 companies actively competing in this exciting new eVOTL space. But the vast majority of these companies are in Europe and China, not the U.S. Why? Because the FAA has been busy protecting Boeing’s back and preventing development of these next-gen aircraft here.

No Matter. Let the Europeans and Chinese get a head start building quiet, electric or hydrogen aircraft. The greatest driver of innovation in the U.S. has always been outside competition—other people beating us at the innovation game. The first computers were built and used in the UK. The first airplanes and rockets were used in warfare by Germany. The first satellite was launched by Russia. So if the world is going to get quiet, non-petro-fueled next-gen aircraft, others will get there first. It’s an old story. But this time, we need Congress and a well-organized, national constituency to stand up and demand that drone makers and eVOTL companies like Lilium explicitly address the noise problem. Otherwise, we may hear them flying over our houses and backyards. We need a say in the process before they land on these shores. That’s what the National Quiet Skies Coalition and the 50 members of the Congressional Quiet Skies Caucus are supposed to be doing.

We need to push them. Now. Get ready.

Nature is remarkable:

This is what a frozen lake sounds like.  , The Verge, writes about “one of the coolest sounds you can hear. A frozen lake that looks like it’s been stopped in time, but in fact keeps shifting and moaning sounding like a Star Wars blaster.”  Sadly, she didn’t have equipment to record the sound, but she found a good example online:

Amazing natural ice pressure sounds of the Gun Lake in British Columbia, recorded by @Mesmerizingsounds.

Enjoy!

 

Let’s find out, shall we?

Can electric sports cars be sporty without any engine noise?  The author of this piece, Jordan Golson, The Verge, suggests the answer is no, because he thinks noise = fun:

Not only does a noisy engine give a visceral thrill, knowing that there are thousands of tiny explosions happening to keep you going, but it just sounds awesome. It would be a shame to lose it, and carmakers know it. Bloomberg says Porsche has been looking at artificially inserting noise into the cabin, perhaps via the stereo like some other manufacturers have done, or amplifying the high-pitched hum of the electric motor.

I don’t know what the answer is, but a world without the roar of a Dodge Challenger Hellcat is a world that’s just a little less fun.

And so the rare opportunity to reduce the overall noise level in our soundscape will likely be ignored, as carmakers will rush to spend big bucks adding unnecessary noise to electric cars because engine noise “just sounds awesome.”  Sigh.

 

Here’s some helpful advice for those who work in open-plan offices:

The best ways to cope with a noisy office.  Rachel Becker, writing for The Verge, is wisely concerned about finding a good option to block distracting noise at work that won’t put her hearing at risk.  Becker notes that “[h]earing loss typically occurs as people age” and that it is irreversible, but what she is concerned about is the World Health Organization’s statement that “more than 1.1 billion young adults are also at risk” of hearing loss because approximately “half of [all] people ages 12 to 35 in middle-to-high income countries are exposing themselves to unsafe levels of noise on their devices.”  That is, younger people are engaging in activities that almost guarantee they will suffer hearing loss as they age, something Becker wants to avoid.

Sadly, her review of options doesn’t reveal a perfect answer.  But her article is important because she is young and aware that she may be able to avoid hearing loss entirely by taking steps to protect her hearing today.  She’s right, after all, about hearing loss being irreversible, and the truth is that no one knows when, or if, a cure will be found.  Since noise-induced hearing loss is 100% preventable, Becker is choosing the wiser route: avoid exposing your ears to damaging sound today to preserve your hearing tomorrow.
