We are proud every time an Atlas goes to a home, a farm or a workshop. When it goes to a university, it feels a little different. Universities are where engineers learn to measure, test and question things, and where the next generation of the energy transition is trained. So let us take a short walk through Dublin, a city built by engineers, on a bay that never runs short of wind.

A university of engineers

TU Dublin was created on 1 January 2019, when the Dublin Institute of Technology and the Institutes of Technology in Blanchardstown and Tallaght joined together to become Ireland's first technological university. Its roots go much further back, to the City of Dublin Technical Schools founded in 1887. Today around 28,500 students study there, from engineering and computing to business, media and culinary arts.

A bay full of wind

Dublin sits on a wide bay that opens straight onto the Irish Sea, between the cliffs of Howth Head to the north and Dalkey to the south. Above the south wall of the port stand the twin Poolbeg chimneys, about 207 metres tall, the highest structures in Dublin and a reminder of the power station that once fed the city. On a breezy day you can feel the wind come in off the water, and Ireland as a whole sits right in the path of the Atlantic westerlies.

A country that runs more and more on wind

Wind already supplies about a third of the electricity on the island of Ireland. In 2024 it covered 32 percent, and in December, when the Atlantic storms roll in, wind alone met 41 percent of demand. Ireland's Climate Action Plan aims for 80 percent renewable electricity by 2030, with 9 gigawatts of onshore wind and at least 5 gigawatts offshore. Big wind farms carry most of that load, but small turbines like Atlas show the same physics at a scale you can touch.

Why Atlas

Atlas is our vertical-axis wind turbine. Because it turns around a vertical shaft, it catches wind from any direction without having to point into it, which suits cities, rooftops and gusty sites. Every Atlas can be fitted with one of three swappable aluminium blade sets: Low-Wind for 2 to 20 m/s, Moderate-Wind for 4 to 25 m/s and High-Wind for 5 to 35 m/s. The blades are 65 percent lighter than steel, so they react the moment the wind picks up. It is compact and easy to watch at work, which makes it a fine turbine for anyone who wants to understand wind power, not just use it.

From the bay to the campus

A small turbine is one of the best ways to make wind energy tangible: you can watch it start in a light breeze, measure its speed, its voltage and its output, and compare the numbers with the forecast. Whatever its new home on campus turns out to be, we are delighted that an Atlas is joining a university with more than a century of technical education behind it. Go raibh maith agat, TU Dublin.

Compressed air powers much of the daily work in a turbine workshop, from pneumatic tools to blow-off guns. Until now the compressor and its air receiver stood inside the production hall, a few steps from the workbenches. They now sit along the outside wall under a new roof, behind timber rails, and the air reaches the hall through a fixed line in the wall.

Why the compressor had to go

A compressor is one of the most useful machines in any workshop, and one of the ones that deserve the most respect. Its air receiver is a pressure vessel that stores a great deal of energy, and the UK Health and Safety Executive lists over-pressure, explosion and overheating among the main hazards of compressed-air systems. A compressor is also loud, and the Carbon Trust estimates that more than 90 percent of the electricity it uses ends up as heat. Inside a production hall all of that sits right next to the people building turbines. Outside, it does not.

How we built it

The shelter is built from sawn timber posts, beams and rails, with corrugated roof sheets that slope away from the building wall so rainwater runs off away from the machines. It stands on the existing concrete kerb that runs along the building, which gives the equipment a solid, level base and a clear edge to the yard. The front and the far end are open above the rails, so air can move freely around the compressor, and two rows of rails keep people and forklifts at a safe distance while still allowing easy access for servicing.

Six safety gains

The move was simple, but it changes a lot inside the hall. The pressure vessel is no longer next to the workbenches. The hall is quieter, so the team can talk and hear warnings clearly. The compressor's heat goes into the open air instead of the workshop. The compressor draws cooler, cleaner outdoor air instead of warm, dusty air from the hall. The roof and rails protect the machines and keep people back. And the floor space it used to take up now goes back to production.

Safety is part of the product

Moving the compressor outside is a small building project with a big effect on everyday work in the hall. We believe a calm, safe workshop builds better turbines, and every Atlas and Magnum we ship is assembled and tested in workshops like this one.

Germany is the land of the Energiewende, the energy transition, and it is also a land of flags, maps and mountains. So before the two turbines reach their new home, let us take the scenic route: from the black, red and gold of the national flag to the black and gold of Baden-Württemberg, from the Rhine plain up to the Black Forest and the Alps.

The fan city

Karlsruhe is one of the few European cities that was drawn before it was built. In 1715 Margrave Karl Wilhelm of Baden-Durlach laid the foundation stone of a new palace in the Hardtwald forest and had 32 streets laid out from its tower like the ribs of a fan: nine of them run south into the town, the rest north into the woods. The plan is so clear that the city is still known as the Fächerstadt, the fan city, and the palace tower still sits at the centre of every map.

Radio waves, the first bicycle and the first car

For a city of its size Karlsruhe has an extraordinary record of invention. In November 1886 Heinrich Hertz, a young professor at the Technische Hochschule, produced and detected electromagnetic waves for the first time, proving that radio waves exist and travel at the speed of light; every wireless signal since has been measured in hertz. Karl Drais, born in Karlsruhe in 1785, built the Laufmaschine, the running machine of 1817 that became the bicycle. Carl Benz, born in the Karlsruhe district of Mühlburg in 1844, built the first petrol car. Today the city is home to the Karlsruhe Institute of Technology, the Federal Constitutional Court and the Federal Court of Justice, and with around 2,000 hours of sunshine a year it is one of Germany's sunniest cities too.

Between the Rhine and the Black Forest

Baden-Württemberg is Germany's third-largest state, home to about 11.2 million people and to engineering towns such as Stuttgart, Mannheim and Heidelberg. Karlsruhe sits on its western edge, on the flat and warm Upper Rhine Plain, a little over 100 metres above sea level. Look east from the city and the land rises quickly: first the dark wooded ridges of the Black Forest, then its highest point, the Feldberg at 1,493 metres, the highest mountain in Germany outside the Alps. Beyond the forest lie the limestone plateau of the Swabian Jura and, on the Swiss and Austrian border, Lake Constance.

A country that runs on wind

No large country has gone further with wind power than Germany. By the end of 2024 it had about 63.5 gigawatts of wind turbines on land and 9.2 gigawatts in the North Sea and the Baltic. Wind produced around 141 terawatt-hours of electricity in 2024, more than any other source, and renewables together covered roughly 55 percent of the country's electricity consumption. The targets for 2030 are 115 gigawatts on land and 30 gigawatts at sea. Most of that is big turbines on the windy northern plains, but the same wind blows over the Rhine valley, and a growing number of German households want a share of it in their own garden.

Two Magnums for Karlsruhe

The order from Karlsruhe is a complete pair: two Magnum horizontal wind turbines, each with a 15 kW motor and a peak output of 12 kW, two Magnum blade sets and two Magnum charge controllers. Both turbines are the battery version with the 0.90 mm winding, which can charge 12, 24 or 48 volt battery banks, so the owner can run them side by side on one bank or feed two separate systems.

Magnum is the largest horizontal turbine we make. Its three aerodynamic blades are balanced for high-speed running, the body is built for year-round outdoor duty, and the charge controller turns the turbine's wild alternating current into clean direct current for the batteries. Two of them on the edge of the Rhine valley, where the westerlies arrive after crossing France, will have plenty to do.

Why small wind suits Germany

Germany has millions of rooftop solar systems, but solar is quiet in the winter months when heating demand is highest. Wind is the opposite: it blows hardest between November and March, and it works at night. A Magnum next to a solar array and a battery bank fills exactly the gap that the panels leave, which is why so many of our German customers combine the two. From the fan city to the Baltic coast, that is the mix the Energiewende is built on, one garden at a time.

Pantelleria is only 83 square kilometres, yet it is the largest volcanic satellite island of Sicily. About 7,150 people live here among black lava rocks, domed stone houses called dammusi, terraces of Zibibbo vines and a turquoise crater lake, the Specchio di Venere. On a clear day you can see the coast of Tunisia. The island is reached by air or by ferry from Sicily, and now also by a TESUP parcel.

Bint al-Riyāḥ, the Daughter of the Winds

The Arabs, who ruled the island from the year 700, called it Bint al-Riyāḥ, Daughter of the Winds, after the strong gales that sweep up from the North African coast. The name fits. Everything people built here was built against the wind. The dammusi have thick dry-stone walls of black lava and low domed roofs that catch rainwater. In the giardino pantesco, a round stone wall shelters a single citrus tree from wind and salt. And the island's Zibibbo vines are grown as low bushes in hollows dug into the soil, out of the wind's reach. In 2014 UNESCO added this vite ad alberello technique to its list of Intangible Cultural Heritage, the first agricultural practice ever to receive that honour.

Born of fire

Pantelleria is the tip of a volcano rising from the sea floor. Two huge eruptions, about 114,000 and 45,000 years ago, left the calderas that shape the island today; ash from the second one has been found as far away as the Greek island of Lesbos. Montagna Grande, at 836 metres, is the summit. The last eruption, in 1891, happened under water off the north-west coast, but the volcano is far from asleep: hot springs bubble along the shore, steam rises from fumaroles, a natural sauna fills a small cave, and the Specchio di Venere lake is fed by rain and hot springs. Since 2016 a national park protects 80% of the island.

An Atlas blade set for the Daughter of the Winds

The parcel on its way across the strait with Poste Italiane contains an Atlas Low-Wind blade set. Every Atlas can be fitted with one of three swappable blade sets: Low-Wind for 2 to 20 m/s, Moderate-Wind for 4 to 25 m/s and High-Wind for 5 to 35 m/s. On an island named after the wind you might expect the high-wind set, but the low-wind blades are a clever choice for many sites. They start turning at just 2 m/s, so the turbine produces in the gentle sea breezes too, not only in the gales. And because the blades are aluminium, 65% lighter than steel, they respond the moment the wind picks up.

Why wind matters on a small island

Like most of Sicily's smaller islands, Pantelleria is not connected to the mainland grid and has to generate its own electricity. That makes every kilowatt-hour produced on the island valuable, and it makes the island's own resources, the sun and the wind that gave it its name, the obvious place to look. A turbine on a dammuso roof is a small step in that direction, and we are glad an Atlas is taking it. To our customer on Pantelleria: grazie, and enjoy the wind.

This is the generator at the heart of the TESUP Atlas wind turbine. We usually show it on the workbench or in a box. This time we simply stopped and looked at it, the way you look at a sculpture.

One line

The body is a single, calm curve of aluminium: up, over and down, with soft rounded corners. Nothing is added for show. The black panel sits inside the curve like a picture inside its frame.

A panel you can read

On the front, everything has its place. Inputs for wind and solar. An output to your inverter or battery. A display and a dial. A sensor socket, an antenna and the connection for the MyTESUP app. The charge controller is built in, so the panel is also where the energy is managed.

Seen from above

From above, the generator is almost a still life: a polished shaft rising from its bearing, a few screws, and a white label with a serial number and QR code. Every Atlas generator carries its own, so each one can be traced from our workshop to its new home.

Why call it art?

Because good engineering and good design end up in the same place: nothing extra, nothing missing. When it is turning in the wind on a roof or a pole, you will not see it this closely. So we wanted to show it to you once, up close.

Pallet by pallet, the stacker lifted every load onto the truck. Each pallet is built up box by box, stretch-wrapped tight and checked before it goes on board.

Loaded and wrapped

Big cube boxes with carry handles go at the bottom, long flat cartons on top, and every box carries its own TESUP label with a serial number. That is how a TESUP pallet travels: as one solid block, from our warehouse to your door.

Atlas generators, ready for the road

Also on board: Atlas generators, each with its charge controller built in. Everything is on one panel: inputs for wind and solar, an output to your inverter or battery, a display and dial, a sensor socket and the connection for the MyTESUP app.

Every unit has its own serial number and QR code, so we can trace each one from our workshop to its new home.

Thank you, Germany

To everyone in Germany waiting for a TESUP turbine: your order is on its way. Thank you for choosing TESUP. We can't wait to see your Atlas or Magnum spinning.

When you tick the battery option on the Atlas or Magnum product page, this is the generator your turbine gets. It is built for 12, 24 or 48 V battery banks, off-grid or as backup.

Why thicker wire

A battery bank works at a low voltage, so the generator has to deliver more current. Thicker wire carries more current, which is why the battery option uses 0.90 mm copper instead of our standard 0.55 mm winding.

60 turns, slot by slot

The stator is a stack of thin steel laminations with a ring of slots inside. Each slot is lined with white insulation, so the copper never touches the steel, and then filled with 60 turns of 0.90 mm enamelled copper wire.

Inverter or battery?

Most homes send their wind power to a grid inverter. For that, the standard 0.55 mm winding is the right choice, and you do not need a charge controller or batteries.

If you charge batteries instead, choose the battery option and your turbine gets the 0.90 mm winding. The Atlas has its charge controller built in and connects straight to the battery. The Magnum connects through the separate TESUP charge controller.

“Artgerechte Tierhaltung steht bei uns im Vordergrund,” the farm says: keeping horses the way horses are meant to live comes first. To make that possible, there are 200 hectares of pastures and meadows where the horses can recover from competitions, training and everyday challenges, and simply grow up healthy.

Life in the herd

Many horses here live in open stables (Offenställe) in small, settled herds: mares and geldings, young and old, from ponies to draught horses. There is a herd of Icelandic horses and a group of seniors, most of them over twenty.

Hay is fed from nets so the horses can nibble slowly through the day, in some stables around the clock. In summer the herds go out to the big pastures, some of them overnight.

Space to roam

Around the farm there are meadows, woods and lakes. Riders can hack out on sandy tracks and paths around the farm without crossing a single road.

Built around the horse

Three stable wings offer boxes and paddock boxes, including a stable for horses with allergies, where they are fed haylage only. For work and recovery there are five outdoor arenas, a 20 × 80 m indoor arena, a lunging hall, a round pen, a horse walker, a solarium, a salt-brine room and washing bays with horse showers.

Dressage riders, show jumpers, leisure riders and carriage drivers all feel at home here.

Why a Magnum fits

A farm like this uses power every day: for the lights in the stables and the indoor arena, for the horse walker and for the solarium. And open Brandenburg land, with wide pastures and few obstacles, is exactly the kind of strong, open wind the TESUP Magnum is built for.

Thank you, Reiterhof Schenkenhorst, for choosing TESUP and for letting us share these photos. We are glad to be part of a place where the horses come first.

TESUP Metal Industries is based in Slovakia and sells aluminium sheets and sheet rolls online at tesupmetal.com. Its products are made in Europe and delivered fast, usually within two days across Europe.

What you can order

• Aluminium Sheet, grade 1050. Flat sheets of 1250 × 2500 mm, in 1.2 mm (10.16 kg per sheet) or 4.0 mm (33.88 kg per sheet).
• Aluminium Sheet Roll, grade 1050. 1.0 mm sheet on the roll, sold by the tonne. How many rolls make up a tonne depends on the thickness.

Why grade 1050

Grade 1050 is commercially pure aluminium, at least 99.5% aluminium. In the H14 temper it is half-hard: strong enough for most general sheet metal work, yet easy to bend and form.

It resists corrosion very well and has a bright, highly reflective finish. That is why it turns up in food containers and kitchenware, architectural flashings, lamp reflectors, cable sheathing and panelling, and in the chemical and pharmaceutical industries.

Need parts, not sheets?

TESUP Metal also offers high-precision custom laser cutting for industry. To ask for a tailored quote, create an account on tesup.com and send us your request.

One family, two jobs

TESUP builds wind turbines for homes. TESUP Metal supplies the aluminium that other workshops and manufacturers build with. Two businesses, one family, and the same care for good material.

An Atlas, with its blade set, is heading to Manawatū in New Zealand. A Magnum is heading to the lakes of eastern Finland. Different turbines, different climates, the same idea: making your own power where the grid is far away, thin or expensive.

18,733 km

That is the straight-line distance from London to Manawatū. London's exact opposite point on the globe lies in the ocean just south-east of New Zealand, so this Atlas is going very nearly to the other side of the world.

Manawatū is one of New Zealand's windiest regions, with wind farms on the ranges above the plains. Out there, a turbine makes power right where it is used, with no long cable run to pay for.

1,992 km

North-east of London, the Magnum is going into the Finnish Lakeland: a maze of lakes, forest and long winters. When the days are short, solar panels do little. That is when wind does the work.

Why remote matters

• The grid thins out. Far from town, power lines are long, costly and the first thing a storm takes down.
• The wind does not. Open farmland, coasts and lakes are often the windiest places of all.
• It travels well. Every TESUP turbine is packed to go as ordinary freight, from a lake in Finland to the North Island of New Zealand.

Every order is a pin on our map. Thank you to both of our new owners. We will be glad to see your turbines spinning.
