The Miller Effect

In this episode - The Miller Effect . . .

The sun hung high in the sky, casting shadows across the desolate landscape of Huron, California. Dr. Vo, a brilliant yet witty electrical engineer, stood before the main breaker box of a massive 1.4 MW-DC solar array that had confounded everyone who had dared to diagnose its persistent issue. It had been six long months of head-scratching and ten failed attempts by others before the desperate call came into Dr. Vo's office.

As the sun's rays bathed the vast array in an orange glow, Dr. Vo stepped up to the Main breaker box, his sharp eyes shaded by his green Cenergy cap. He wore his North Face jacket that billowed in the light breeze, and his presence exuded an air of mystery and intrigue that was as pervasive as the problem at hand.

The solar array was a colossal assemblage of panels, wires, and inverters, but the main breaker kept tripping, sending the entire operation into chaos. The workers at the site were on edge, muttering, “We’ve tried everything. This main breaker keeps tripping.” Dr. Vo turned as the technicians approached the Point of Interconnection (POI) main breaker, where they dragged bags of tools to the panel's layout. The tension at the Farm was palpable, and nervous glances followed Dr. Vo's every move.

"Who's in charge here?" Dr. Vo inquired, his demeanor unwavering. A middle-aged man, obviously flustered, stepped forward. "I'm Peter, the project manager," he stammered.

"Peter, tell me everything you know about this problem," Dr. Vo ordered as he drank his refreshing water and gazed at the panel board.

Peter explained, "The main breaker keeps tripping. It's been happening for months, and we've tried everything. We've swapped out inverters, replaced panels, and rewired sections of the array; nothing works. We've lost a fortune, and if we can't get it running, we're finished.”

Dr. Vo nodded, listening intently. He then asked Peter to remove the main panel board cover and hand him “The Meter.” He began eliminating, step by step, each component that could cause the problem. “Well, it's not the main breaker – it's fine. Let’s move to the main combiner box where all the inverters are connected.”

With patience and precision, Dr. Vo had his team systematically shut down each of the nine string inverters and, with his trusty multi-meter, eliminated each inverter one by one. “Ah, he said, it looks like Inverter Number One is the cause of the problem.”

Everyone on the inverter pad fell silent as they awaited his next move. Dr. Vo requested Nhon to back the truck up to the inverter so we could use the tailgate as a ladder and, with the utmost care, climb up to the inverter connection box. He smelled the panel and traced the wires, testing the resistance as he went, his fingers moving like a maestro conducting a symphony of electrons. After about an hour of meticulous testing, Dr. Vo descended the ladder. He looked at the O&M team with a triumphant smirk and uttered, "You have a case of The Miller Effect.”

Baffled, the team erupted in confusion. "What is the Miller Effect?”

"The Miller Effect is a tricky thing, known for capacitance amplification. It was causing your main breaker to trip. You had an unintended capacitance coupling that no one noticed. I’ve reconfigured the connections to take this inverter offline. A damaged underground wire is causing the problem, and condensation has penetrated this wire; we will need to replace it.”

The array suddenly sprang to life after bypassing Inverter One and turning all the breakers back on. The monitors displayed a steady flow of electricity, and the team couldn't believe their eyes. Dr. Vo had performed a miracle that had eluded everyone.

As the array hummed with renewed vitality, Dr. Vo adjusted his coat and tipped his hat to the astonished onlookers. He turned and disappeared into the fading light of the California sunset, leaving behind a riddle solved and a mystery unraveled, much like the iconic detectives of a bygone era.

I'm Patrick Ball; thanks for listening. See you in the next episode.

Confidently Wrong: The Art of the AI Tall Tale

In this episode, A chat with Adamas the Chef on hidden recipes causing digital hallucinations. Pull up a chair and pour yourself a fresh cup of coffee—and please, for your own sake, taste it first. We need to have a quiet chat about why your computer sometimes decides to reinvent reality with the confidence of a five-star chef who has clearly lost his mind. In the world of technology, we call it a  hallucination . It sounds pretty dramatic, doesn’t it? As if the computer decided to ignore your instructions altogether in favor of a vivid, technicolor imagination that simply hasn’t met reality yet. But in truth, an AI hallucination isn’t a breakdown; it’s just a very confident, very polite mistake. Think of it like our friend Adamas , the Chef. Adamas is a master of the kitchen, but he is also a bit of a romantic who refuses to say “I don’t know.” When you ask him for a classic recipe he hasn’t made in years, he doesn’t stop to consult a cookbook—that’s far too pedestrian. Instead, ...

Opening Day Magic 2026 . . .

It’s back. Baseball—yes, baseball ! If you’re someone who finds themselves inexplicably drawn to this peculiar ritual, let’s be honest with each other: it’s a bit odd, right? I mean, 162 games. That’s a lot of hot dogs, a lot of standing around, and a lot of grown men in oddly tailored trousers spitting with remarkable precision. And yet, here we are, poised on the precipice of another season. Thursday, March 26, 2026, to be precise—Opening Day. It’s a curious thing, this Opening Day. You walk into a stadium, or turn on the TV, and suddenly, everyone is infected with a highly contagious strain of . . . Optimism . It’s a spectacular form of collective amnesia. All of last year’s fumbles, the endless losing streaks, the existential dread of watching your bullpen implode in the eighth inning—poof. Gone. It’s entirely replaced by a wide-eyed, childlike belief that this year, finally, the baseball gods will smile upon us. The Cycle of Hope and Despair As a Cubs fan, I know this cycle intim...

Overcooking the Grid

In this episode, terrified of smart toasters, yet demanding infinite electricity for potato personality tests. Pull up that chair again, and let’s hope your coffee is safe this time. In our last chat, we talked about our well-meaning but occasionally delusional AI friend, Chef Adamas, and his penchant for hallucinating blueberries into your Carbonara. We learned how to manage his quirks by keeping our “digital pantry” organized. But today, we need to look past the chef and take a hard look at the sheer size of the kitchen we are building for him. And folks, that kitchen has gotten completely out of hand. Down in Louisiana, tech companies are currently building an artificial intelligence data center the size of 70 football fields. It is a four-million-square-foot digital brain that requires so much electricity they are building three new natural gas power plants just to keep the servers from literally melting down into a puddle of expensive silicon. And what are we using this god-like, ...

Vintage Vinyl

In this episode - Vintage Vinyl . . . Turntables are making a big comeback; why? Listening to music should be a multi-sensory experience. Harmony, rhythm, and the deep expression of emotion. Like a warm, gentle rain in the springtime cascading around you the room is filled with a resonant, rich, melodic sound. My emotions welled up, and tears come to my eyes. Ok, I get it, we need to step back to get some perspective here. Recently a visit to Lou's Records in Encinitas, California, inspired me to dig out my Vintage vinyl LP record collection. I selected the Carpenters Singles 1969- 1973 . This musical duo reigned from 1969-to 1982 with the rich, full melodic voice of Karen Carpenter. They were one of the biggest-selling groups of the 1970s. "No fewer than ten of their singles went on to become million-sellers, and by 2005 combined worldwide sales of albums and singles well exceeded 100 million units." The tactile sensory experience of music begins with the album cover it...
