Chapter 114: Going to Work
The following morning, Ernest remained in his bedroom long after breakfast should have begun.
Sunlight spilled through the tall windows of Oriel Estate, touching the edge of his desk, the folded maps, and the notebook he had filled the previous day at Beryl District. Outside, the estate grounds moved quietly beneath the morning mist, but Ernest barely noticed any of it.
His attention remained fixed on the survey notes spread across the desk.
For once, the problem in front of him was not political, financial, or tied to some minister misunderstanding electricity.
There was a source of water. There was a difference in height. There was a route for a pipe. There was a need for power.
Those were his favorite kinds of problems.
He wrote the first numbers at the top of a fresh page.
The intake point sat at roughly 164 meters above sea level. The proposed powerhouse location near the lower valley measured around 138 meters. That gave him an available head of approximately 26 meters before pipe losses. The stream’s estimated dry-season flow was 0.8 cubic meters per second, though wet-season flow would be much higher.
He underlined the dry-season figure.
"Design for the worst month, not the best one," he muttered.
A careless engineer could use peak wet-season flow and produce impressive numbers on paper. Ernest had no interest in a station that worked beautifully during storms and disappointed everyone during dry months. Real systems had to be built around the minimum dependable supply. Anything above that was only a bonus.
He tapped his pencil against the page.
Twenty-six meters of head placed the site in an interesting range. It was too high for a traditional waterwheel to use well, but nowhere near the mountain drops where a Pelton turbine would dominate. The stream had moderate flow and moderate elevation.
That pointed toward one answer.
"A Francis turbine," he said quietly.
For once, nature had made the selection easy.
A Francis turbine suited sites like this. Water entered under pressure, passed through guide vanes, and struck curved runner blades that extracted energy from both pressure and flow. It was not a crude wheel being pushed by water. It was a carefully shaped machine that converted falling water into rotation with far greater efficiency.
More importantly, Helmarte Machine Works could build it.
Not easily.
But they could.
Ernest began sketching the layout.
The intake structure would sit upstream where the stream narrowed naturally between rocky banks. A low stone weir, perhaps four meters tall, would raise the water level enough to form a small pond without flooding the surrounding fields. The purpose was not to create a massive reservoir. It only needed to keep the intake submerged and give sediment a chance to settle before the water entered the pipe.
He drew the intake house next.
A steel trash rack would block branches, leaves, and stones. Behind it, a gate would allow workers to shut off the flow during maintenance. A settling chamber would slow the water long enough for sand and grit to fall out before reaching the turbine.
"Grit will eat the runner alive if we ignore it," he murmured.
Then came the most important part.
The penstock.
The pipe would carry water downhill from the intake to the powerhouse, turning elevation into pressure along the way. Steel would have been ideal, but large steel pipes were still expensive and difficult to produce consistently. Cast iron was heavier and less forgiving, but it was within their current capability.
His pencil moved across the page.
Penstock diameter: 700 millimeters.
Length: approximately 420 meters.
Burial depth: 1.5 to 2 meters.
The pipe would follow the natural slope beneath the hillside before emerging at the powerhouse near the estate. Burying it would protect it from weather, damage, temperature changes, and curious workers who might decide to investigate a giant pipe running across the land.
Ernest smiled faintly.
Especially the last one.
He shifted to the calculations.
Hydraulic power was simple in principle. Water density multiplied by gravity, flow rate, and head. The stream provided the mass. The hillside provided the height. Gravity did the work.
At 0.8 cubic meters per second and 26 meters of head, the theoretical hydraulic power reached a little over 200 kilowatts.
Real machines were never perfect.
The penstock would lose pressure through friction. The turbine would lose energy through turbulence, imperfect blade geometry, and mechanical drag. Bearings would generate heat. The generator would lose power in the windings. Transmission lines would lose a little more as electricity moved toward the estate.
Assuming an overall efficiency of seventy percent, he could still expect roughly 140 kilowatts during dry season.
Ernest leaned back in his chair and stared at the number.
One hundred and forty kilowatts.
By the standards of his previous world, it was tiny. A modern factory would consume several times that without noticing. A city would treat it as almost nothing.
But for a private estate in this world, it was absurd.
The manor itself would likely consume less than ten kilowatts even with generous lighting. Workshops, pumps, laboratories, and exterior lamps might use another few dozen. Even then, most of the power would remain unused at first.
That opened possibilities.
Small motors could drive lathes, drills, fans, and pumps without needing steam shafts running through every workshop. Estate roads could have electric lamps. Laboratories could run tests without consuming batteries like expensive candles. Oriel might become the first electrified estate in history almost by accident.
He looked toward the window.
Beyond the glass, morning mist drifted above the fields.
The world outside still belonged to oil lamps, candles, fireplaces, and muscle power.
On his desk, however, the numbers were already arguing for something else.
The turbine and generator were difficult, but possible. The true challenge would come afterward.
The light bulb.
Ernest turned to a new page.
Generating electricity was only half the problem. Using it well was harder. A lamp needed a filament that could become hot enough to glow without burning away at once. It needed a glass bulb. It needed most of the air removed from inside, because oxygen would destroy a hot filament almost instantly. It needed sealed metal connections that passed through glass without cracking it.
Most of all, it needed the right material.
He closed his eyes for a moment, reaching into memories from a world that no longer existed for him.
Early incandescent lamps had failed constantly. Filaments burned out. Vacuums leaked. Glass cracked. Materials degraded. Practical lighting did not come from one clever idea. It came from hundreds and thousands of tests eliminating what did not work.
He did not have the luxury of thousands of tests.
But he had memory.
"Bamboo," he whispered.
Carbonized bamboo.
In his previous world, carbonized bamboo filaments had been one of the first practical solutions for incandescent lamps. When cut thin, heated without oxygen, and sealed inside a good vacuum, bamboo fibers could become carbon filaments that glowed for a useful length of time.
Belfast had bamboo in its southern coastal provinces.
Not the exact species he remembered, most likely.
But perhaps close enough.
What mattered was fiber structure, uniformity, and whether the material could carbonize without crumbling.
He wrote another heading.
Lamp Development.
Bamboo samples from southern provinces.
Carbonization furnace.
Improved vacuum pump.
Glass bulb uniformity.
Sealed electrical contacts.
He stared at the list.
The work would be delicate.
Frustrating.
Expensive.
But not impossible.
Glassmakers could produce bulbs with enough training. The machine works could build better vacuum pumps. Copper wiring already existed because of the telegraph. Generators were within reach. The filament would be the most uncertain part, but uncertainty did not mean impossibility.
He turned back to the hydroelectric sketch.
The telegraph had started this chain.
A king wanted faster military communication, and now the kingdom was making better wire, better insulation, better batteries, better switches, and better electrical instruments. Every solution created tools for the next invention.
Electricity would not arrive in one grand moment.
It would arrive through practical needs.
A message needed to move faster.
A lamp needed to burn longer.
A workshop needed power without steam shafts.
A manor needed light without candles.
Ernest looked down at the page where the turbine, penstock, generator, and lamp notes had begun to merge into a single plan.
The first power station would not begin in the capital.
Not in a university.
Not in a royal laboratory.
It would begin beside Oriel Estate, in a quiet valley where falling water could be persuaded to spin a machine.
He dipped his pen again and wrote the final title across the top of the page.
Oriel Hydroelectric Station.
Then he sat back and allowed himself a small smile.
The stream at Beryl had flowed downhill for thousands of years without anyone asking more from it than turning a mill wheel or watering fields.
Soon, if his calculations held, it would do something entirely new.
It would carry gravity through a pipe, spin iron and copper, and turn falling water into light.
