The Real AI Bottleneck Is a Few Inches Long

Most people think AI has a power problem. That’s only half right…

Yes, these new AI factories need enormous amounts of electricity. And yes, they need a lot of water to keep from cooking themselves.

But the reason so many of them are getting killed before a shovel ever hits the dirt isn’t that America can’t build them.

It’s that their neighbors won’t let them…

Take the Prince William Digital Gateway in Northern Virginia. It was the largest data center project ever proposed in the U.S.

We’re talking roughly 2,100 acres, more than 20 million square feet of buildings and an estimated $100 billion at full build-out.

The developers, Blackstone-owned QTS and Compass Datacenters, had the land. They had the money. They even had the county’s approval, after a marathon 27-hour hearing.

But from the start, the neighbors had two big worries.

The first was water.

The site sat in the Occoquan watershed, which feeds a drinking water supply for more than a million Northern Virginians.

Fairfax Water, which treats drinking water for over 2 million people in the region, asked for a study of what turning that much rural land into an industrial campus would do to the reservoir. And Fairfax County supervisors urged Prince William to wait for the results before voting.

The second was power.

Beause a multi-gigawatt campus means new transmission lines, new substations and a big question for everyone else on the grid: Who pays for all of it?

The numbers weren’t encouraging at all, either…

A 2024 state audit estimated Dominion Energy may spend $16 billion to $18 billion by 2040 on transmission tied to data centers.

And under the current setup, residential customers would cover 55% of that bill. The data centers would cover 26%.

In plain English, Virginia families were on the hook for more than twice as much of the new grid as the companies that actually need it.

And it’s not just Virginia.

The Union of Concerned Scientists found that in 2024 alone, utility customers across the PJM grid were billed about $4.3 billion for transmission projects that were needed only to connect data centers.

Add the Manassas National Battlefield right next door, and you had more than 30 environmental and historic preservation groups lined up against it, along with the National Park Service and dozens of homeowner associations.

Residents took it to court. A judge voided the rezoning because of how the county advertised its hearing, and the state appeals court agreed. On July 2, QTS withdrew its last appeal and walked away.

On paper, the biggest data center project in American history died over a technicality.

But in reality, it died because the people living next to it didn’t think it was worth their drinking water and their power bills.

And that’s not a one-off. It’s becoming the norm.

The Pattern

Just look at the numbers…

In the first three months of this year, local opposition blocked or delayed at least 75 U.S. data center projects worth about $130 billion. That one quarter roughly matched all of 2025.

And it’s only gotten worse from there.

By the end of September, at least $260 billion in data center investment had been canceled outright after local pushback. That’s more than every data center project canceled in all of last year.

And that’s probably an undercount because only about 60% of projects even disclose how much they’re worth.

And the fight has moved well past the county level. Lawmakers in at least 14 states are now considering moratoriums or outright bans on new data center construction.

And the public is on the neighbors’ side. A Gallup survey in May found 71% of Americans oppose building a data center in their area.

In plain English, the chips exist. The money exists. The demand is off the charts. But what’s missing is permission.

Now here’s what bugs me about the way this story usually gets told…

Almost every article frames it the same way: AI needs more power, AI needs more water, so the industry has to go find more of both.

But that’s the wrong question. And as long as “we need more” is the only answer on the table, those county boards are going to keep saying no.

Less Waste, Not More Supply

The better question is this: How much of the power these buildings already use is being wasted?

Because we’ve seen this movie before…

Every time a new technology starts straining the system, the first instinct is to build more supply.

But the bigger, longer-lasting wins usually come from the companies that make the system more efficient.

And to see where the waste is hiding in a data center, you need to understand one thing about how data moves.

Light Beats Copper

The fastest connection we have is fiber optics.

Instead of pushing electricity through metal wire, fiber sends data as pulses of light through strands of glass thinner than a human hair.

You see, light doesn’t fight resistance the way electricity does in copper. So it carries more data, over longer distances, with far less energy lost along the way.

And that’s why fiber is what the modern internet runs on…

It carries your video calls across oceans. And it’s a big reason 5G works at all, because thousands of new cell sites need a connection fast enough to keep up.

And fiber is the fastest, highest-capacity connection we have.

It’s also how data moves around inside every major data center in the world.

So far, so good. But there’s a catch…

The Last Few Inches

If you’ve ever tracked a package, you already know the shipping industry’s biggest headache. They call it the last mile.

A box can cross the country relatively cheaply in a day on planes and trucks. Then the trip from the local warehouse to your front porch eats up a big share of the total cost.

Data centers have the same problem. But for them, it’s the last few inches.

Think about how this works…

Light races across the building through fiber. But fiber stops at the edge of the server.

For the final stretch, from the edge of the board to the chip itself, the data gets handed back to copper and pushed through as electricity.

So you’ve got data crossing an entire continent at the speed of light… only to hit a copper bottleneck about the width of your hand.

And here’s why that matters: copper resists the current running through it.

At the speeds AI demands, that resistance turns into heat.

And every bit of that heat has to be pulled out of the building by fans, chillers, and cooling towers, which burn more power and, in a lot of places, evaporate away millions of gallons of water.

Simply put, some of the power and water these towns are fighting over is being spent on one job: moving data the last few inches through metal that was never built for this kind of speed.

The Fix

Now imagine letting light handle those last few inches too…

No hand-off back to copper. No heat piling up at the bottleneck. Data moving as light almost all the way to the chip.

That’s exactly what one small company has spent years building.

It’s developed a patented material that converts electrical signals into light and back again, faster and with far less power than the parts in use today.

To be clear, the chips still do their thinking with electricity. That part doesn’t change.

But what changes is the wiring around them, which is the part that’s been eating power and throwing off heat.

And the chain reaction is pretty simple…

Less wasted power means less heat. Less heat means less cooling. Less cooling means less water. And a data center that needs less of both is a whole lot easier to get past a county board.

Big Names Are Already on Board

This isn’t a lab experiment sitting on a shelf, either.

The company is already working with at least four of the world’s largest corporations to bring its technology to market.

Think about who’s spending the most to build AI right now: Google, Microsoft, Nvidia, Amazon, Meta.

Those are the companies with the most to gain from cutting power and cooling, and the most to lose every time a project gets voted down.

And yet the company behind this technology is still small enough that most investors have never heard its name.

Because while Wall Street is busy pricing in the companies that need more power, it hasn’t caught on to the one that helps them need less.

Why Now

Here’s how I see this playing out…

Every data center that gets voted down makes efficiency more valuable.

The builders who can walk into a hearing and say “we’ll need less power and less water” are the ones who get their permits. And the ones still asking for more will keep losing.

So the biggest spenders in tech have every reason to move fast on anything that gets their projects approved.

And when that happens, a company this small, sitting on technology this important, doesn’t creep higher.

It gets repriced.

My colleague Jason Simpkins has been digging into this company for months. And he’s put the whole story into a new report you can get for free.

Inside, you’ll get the company’s name and ticker, a rundown of its patents and partnerships, and why he believes the window to get in early won’t stay open long.

So, if you want to see who’s solving AI’s last-inch problem, I suggest you start here.

Because when everyone else is fighting over more power and more water, I’d rather own the company that helps AI need less of both.
