Vacuum Tubes and skill in making glass going way back. Enough to convince me to do it for the military one.
Hae raht- The Steam PaddleboatHae raht- The Steam Paddleboat. Where the rest of the world entered the age of sails, Etroa entered the age of Steam. With greater access to materials, and techniques from afar, Mad Rúatan and Tric Ingóle worked together. Utilizing ancient designs long since discarded, they saw the potential of a ship that traveled perpetually.
In this, Mad Rúatan designed the ship, and Tric Ingóle the propulsion.
Taking wood, they designed the first screw pipe. These pipes were carved with metal to have grooves, which slotted together. They then made a chamber of wood and metal, and placed cut sunshards in it before closing it with a top, carved with tubes sticking out the top, those tubes having a screw carved into their outer section. Then, more pipes were screwed on, inner carvings fitted onto the outer carving, and sticky rubber glues made from the Rubber Tree used to seal it tight.
Leading from the top of this chamber, the pipes led to the first bit of metal. A fan-wheel stationed inside a chamber. It's shaft moving into the container's wall was sealed as best it could, and had a large gear attached at the other end outside.
As the would steam rise, it would pass the fan-wheel, turning it's blades from the immense pressure being produced by the sunshard boiled water.
This steam continued on into the upper pipe on the other side, before curving back around. Here, the recent discovery of moonseeds, which could be made by leaving a sunseed buried in very cold conditions, made it's appearance. Moonseed inset into a wooden cage. Here, the steam ended it's journey. In this container, mirroring the sun chamber, the steam gathered and condensed into clouds which then rained down the holeat it's bottom. For the hole the steam entered was from the side.
Down it fell, past other small moonshard fragments inset into the pipes, before bottoming out, flowing into the Sun Chamber from the side like a waterfall.
During normal operation, steam produced would flow into the pipe leading up and to the side pipe. However, the moonshard fragments rendered that side journey impossible. It would cool and freeze long before reaching the Moon Chamber that way. And in this manner, there was a cross-pipe. This cross-pipe led off not to the Sun or Moon chamber, but outside. Normally closed off during operation to maintain high, continual pressure in the system, when the metal and rubber caps was opened up, one can pour a large amount of water inside. By using sea water purified by sunseeds, one could fill the Boiler. And at the bottom of the path the water would normally flow before entering the Sun Chamber was another cap on a small subsection cross-pipe. Opening this one would let the water spill out before reaching the Sun Chamber.
It is the world's first Boiler. We have neglected to descirbe what it turns though. The gear is directly connected to a number of other gears. Which lead to one final gear. And this gear, a masterwork of Etroan Engineering, would be connected to a huge paddle outside, spanning the rear of a ship.
The Boiler is right next to the Paddle. And this paddle turns continuously and steadily. The more water is used in the Boiler, the faster it spins, and the quicker the attached boat moves.
When not active, a single gear has a attached pole one can use to remove it, which cuts off the connection between boiler and paddle.
In this manner, along with rudders, a boat that requires neither winds nor current to travel at a steady pace across seas and rivers.
