Introducing...Haitz's Law.

Hope you had a good weekend. This year marks the 200-year anniversary of Charles Babbage’s Difference Engine, which inspired the first computer.

Babbage eventually drew up plans for a more ambitious, general-purpose computing system called the Analytical Engine. In 1843, that theoretical machine became the system for which Ada Lovelace, a colleague of Babbage’s, wrote what is considered the first computer program

The “law” enabling vertical farms to flourish

Chances are, you’ve heard of Moore’s Law, the “social fact” that has explained semiconductor progress for over half a century. But how about its lesser-known, distant cousin, called Haitz’s Law, which theorizes the rate of progress in LED lighting, a critical enabling technology for indoor farming?

The law is named after Roland Haitz, a scientist who worked for Hewlett-Packard and Agilent Technologies, who posited in 2000 that every 10 years the amount of light generated by an LED bulb increases by a factor of 20, while the cost per lumen (unit of useful light emitted) falls by a factor of 10. And since then, it’s mostly held true.

  • To put Haitz’s Law in even more plain terms: LEDs have become more powerful while also becoming less expensive.

Why it matters: This advancement has been critical for the indoor farming sector, as the expenses of powering a farm packed with HVAC systems, hydroponic infrastructure, and thousands upon thousands of bright, 24/7 lights can add up.

  • In some operations, LED lighting alone can account for between 50% and 65% of the electric bill, according to the 2021 Global CEA Census Report.
  • AppHarvest, an indoor grower based in Morehead, Kentucky, uses over 30,600 LEDs in one farm.

The LED lighting market was worth nearly $69 billion in 2021, per IMARC research, led by manufacturers like Philips Lighting, Samsung, Acuity Brands, and GE Lighting, and the firm estimates it will reach $121 billion by 2027. Falcone also pointed to Sananbio, a lighting company focused specifically on indoor farming.

Looking ahead...Vertical farming execs told us the law's progress could taper off in the next decade or so.

“We’ve seen efficiencies on the cost of lights themselves, and we certainly see lots of efficiencies in terms of the fixtures and how efficient they are with the energy,” Fain said. “There will be a plateau…But even if Haitz’s Law plateaus, it’s still come a meaningfully long way, and then there’s other areas for innovation around the light that can create even further efficiencies as well.”

Marketers in the metaverse

“Strap on your VR glasses; we’ve got a meeting” could become a common refrain for marketers.

Why? Several agencies and marketing firms have already invested in VR headsets like Meta’s Oculus, indicating that, one day, the metaverse could be the industry’s new Zoom.

  • Some are hosting annual summits in VR. Others are shifting meetings from Zoom to VR workspaces like Horizon Workrooms (which is currently in beta testing), or experimenting with VR glasses and platforms like Decentraland to better advise clients on the subject.
  • One CEO told us he bought his employees Oculus headsets just so they could bond over activities like VR minigolf.

“The technology allows us to connect in ways better than having the bat phone in the middle of the conference table and everybody shouting into it,” Simeon Edmunds, SVP and creative director of Mediahub’s R+D Lab, told Marketing Brew. “We’re finding usefulness not just in helping us produce a better work product, but also in understanding what’s emerging.”

Mediahub started using the metaverse in December—specifically rented land in Decentraland—as a recruitment tool to differentiate itself from its competitors, Edmunds told Marketing Brew.

Edmunds and R+D Lab creative technologist Lacey Nein hosted a class on the metaverse and one on NFTs, Nein told us, and the agency has been setting up VR headsets in rooms at some of its offices around the world for employees to test out when they stop by, according to Edmunds.

  • He estimated that more than 40% of Mediahub staffers globally have tried them out so far.

“We’re not trying to force people into this thing,” Edmunds said. “We want them to see, ‘Oh, this is cool,’ and then move from that.”

Coworking is a weekly segment where we spotlight Emerging Tech Brew readers who work with emerging technologies. Click here if you’d like a chance to be featured.

How would you describe your job to someone who doesn’t work in tech?

I’m helping enterprise and fast-growing companies to make fact-based decisions on a large scale. It requires a surprising amount of effort to gather the facts at a very granular level and draw reliable high-level conclusions out of it. There are both technological and scientific challenges to doing it well.

What’s your favorite emerging-tech project you’ve worked on?

AI for detecting brain tumors. It automatically analyzes MRI scans and, within a few minutes, supports the doctor with suggestions of where the suspected regions are. This delineation and a few supporting metrics may be used to assess cancer severity or adjust therapy for specific patient needs.

What emerging tech are you most optimistic about? Least? And why?

That’s a tough choice. For most optimistic, I see two:

  • Low/No-code “modern” data stacks. They introduce a lot of simplicity and require much less maintenance. This will decrease the barrier for large-scale data utilization.
  • Recent self-supervised and unsupervised NLP breakthroughs. Their utility is often confirmed far beyond text in images, audio, and other kinds of data. Moreover, a major part of model training can be conducted without massively annotated data, like with Wikipedia.

I’m least optimistic about some ideas around NFTs in the metaverse. Digital goods are in most cases almost infinitely replicable. Building an NFT-only metaverse would introduce serious limits to that and would change the digital reality forever.

One thing we can’t guess from your LinkedIn profile?

It may sound like a slogan, but I strongly believe that changes related to emerging tech need to be designed with people in mind. A lot of engineers designing data/ML/other solutions focus on technological integrations only, but forget about the people that will actually be influenced by the developed system. At the same time, these people will be crucial for the success of the solution.

What do you think about when you’re not thinking about tech?

My family and food. We love cooking together and experimenting in the kitchen. It often feels like a home chemistry lab.
