The aeolipile is considered to be the first recorded steam engine or reaction steam turbine, but it is neither a practical source of power nor a direct predecessor of the type of steam engine invented during the Industrial Revolution.[4]
Due to its use of steam as the medium for performing work, the Aeolipile (in profile view) was adopted as the symbol for the U.S. Navy's Boiler Technician Rate - which had formed out of the Watertender, Boilermaker, and Boilerman ratings (that used the same symbol).
The aeolipile usually consists of a spherical or cylindrical vessel with oppositely bent or curved nozzles projecting outwards. It is designed to rotate on its axis. When the vessel is pressurised with steam, the gas is expelled out of the nozzles, which generates thrust due to the rocket principle[5] as a consequence of the 2nd and 3rd of Newton's laws of motion. When the nozzles, pointing in different directions, produce forces along different lines of action perpendicular to the axis of the bearings, the thrusts combine to result in a rotational moment (mechanical couple), or torque, causing the vessel to spin about its axis. Aerodynamic drag and frictional forces in the bearings build up quickly with increasing rotational speed (rpm) and consume the accelerating torque, eventually cancelling it and achieving a steady state speed.
Typically, and as Hero described the device, the water is heated in a simple boiler which forms part of a stand for the rotating vessel. Where this is the case, the boiler is connected to the rotating chamber by a pair of pipes that also serve as the pivots for the chamber. Alternatively the rotating chamber may itself serve as the boiler, and this arrangement greatly simplifies the pivot/bearing arrangements, as they then do not need to pass steam. This can be seen in the illustration of a classroom model shown here.
Aeolipilae are hollow brazen vessels, which have an opening or mouth of small size, by means of which they can be filled with water. Prior to the water being heated over the fire, but little wind is emitted. As soon, however, as the water begins to boil, a violent wind issues forth.[6]
No. 50. The Steam-Engine.PLACE a cauldron over a fire: a ball shall revolve on a pivot. A fire is ignited under a cauldron, A B, (fig. 50), containing water, and covered at the mouth by the lid C D; with this the bent tube E F G communicates, the extremity of the tube being fitted into a hollow ball, H K. Opposite to the extremity G place a pivot, L M, resting on the lid C D; and let the ball contain two bent pipes, communicating with it at the opposite extremities of a diameter, and bent in opposite directions, the bends being at right angles and across the lines F G, L M. As the cauldron gets hot it will be found that the steam, entering the ball through E F G, passes out through the bent tubes towards the lid, and causes the ball to revolve, as in the case of the dancing figures.[1]
It is not known whether the aeolipile was put to any practical use in ancient times, and if it was seen as a pragmatic device, a whimsical novelty, an object of reverence, or some other thing. A source described it as a mere curiosity for the ancient Greeks, or a "party trick".[7] Hero's drawing shows a standalone device, and was presumably intended as a "temple wonder", like many of the other devices described in Pneumatica.[clarification needed][1]
In 1543, Blasco de Garay, a scientist and a captain in the Spanish navy, allegedly demonstrated before the Holy Roman Emperor, Charles V and a committee of high officials an invention he claimed could propel large ships in the absence of wind using an apparatus consisted of copper boiler and moving wheels on either side of the ship.[8] This account was preserved by the royal Spanish archives at Simancas.[9] It is proposed that de Garay used Hero's aeolipile and combined it with the technology used in Roman boats and late medieval galleys.[8] Here, de Garay's invention introduced an innovation where the aeolipile had practical usage, which was to generate motion to the paddlewheels, demonstrating the feasibility of steam-driven boats.[9] This claim was denied by Spanish authorities.[10]
HeroEngine is a 3D game engine and server technology platform originally developed by Simutronics Corporation specifically for building MMO-style games. At first developed for the company's own game Hero's Journey, the engine won multiple awards at tradeshows, and has since been licensed by other companies such as BioWare Austin (which used it for Star Wars: The Old Republic[1]).
The engine has online creation. For example, one developer can be creating a house and the entities inside, while another works on the landscaping and terrain around it. Each sees the other's work in real time.[3]
The simulation and rendering processes of the engine are currently run on a single-thread. However, it is planned for there to be a multi-threaded release, but the publish date has not yet been determined.[4]
HeroBlade contains integrated features such as custom scripting and collaborative project management, which allow developers to make notes directly onto the in-game levels for others to see.[6] These notes can be attached to tasks to signal other developers that something specific needs to be worked on.[7] HeroEngine also works with technology from third-party vendors,[8] such as FMOD, PhysX, SpeedTree, Wwise, Scaleform, and Vivox, as well as having plugins for 3D Studio Max and Maya.
HeroCloud was a version of HeroEngine that was available for $99 per year, under the license that they received 30% the money sales of any game made with it. It included everything that a license to the HeroEngine had, except for access to the source code.[9]
The company chairman of Idea Fabrik announced on 6 November 2015 that they were having funding issues related to an unnamed 3rd party, which could cause downtime on their HeroEngine and HeroCloud services. He stated that they were attempting to resolve and were "currently in negotiations to secure [their] funding for the present and the future."[11]
seems like another one of the big dogs will be free to use, this is fantastic.

the new owner of hero engine are announcing free to use of the hero engine with a royalty deal, like UDK.
I do wonder as to how this will work. Will they give you the server or still keep it in the cloud? If cloud, then how will they keep it up without losing money(hence the 1k a year free to pay for cloud)
Its not the HeroEngine though
The page clearly implies that its more like a Habbo - Facebook Game sandbox that builds upon the solid bases HeroEngine / HeroCloud has but without exposing all the power (If you used it you know that the learning curve potentially is even higher than on UDK)
This is further raised due to the pure browser targeting.
This system is even easier than HeroEngine, as you dont need to deal with any sort of management, or complex networking, you only create your game live, with your team in real time and dont worry about the rest.
well both versions, ideasys for light social browser games using heroengine tools.
and herocloud basic using heroengine tools aswell. difference will be world size restrictions. but will be able to use all heroengine tools and backend technology as per faqs:
there are threads in mmorpgmaker forum from heroengine staff themselves answering questions about it.
Anyways its stupid that they show gameplay footage at extremly low frame rate. I have tested some scenes in this engine on myself and it runs very very slow. I think that engine isnt optimised at all. Shadows are supported but you have to coope with 5 frame gameplay in that case.
You can try it out for free, but unless you have deep pockets, this is not for indies.
HeroEngine really is easy to use, although I have never scripted for it, I have seen it work first hand, and all I can say is WOW.
But again, different market than Unity all together, so not even a competitor, UT and HeroEngine do not compete.
ok back to topic:
I think it is great, pretty much a high percentage, probably 80% of any engine users are individuals and or small indie studios, with mostly
low to none budget to startup a game dev deal.
but the great thing is that there is so much talent out there, and now the tools being free to use, this will create a new wave of games to the market,
I bought this model for my son for Christmas as he is interested in mechanical things. It arrived quickly and was very well packed. The model is well made and only needs a syringe and liquid fuel to get it running. It demonstrates Hero's design very effectively and makes a great Christmas present that will last years.
The engine is very simple to operate and the best performance is achieved by using unadulterated ethanol as fuel. The bearing has no obstructions and the engine rotates freely. Although not required, I would have appreciated if there was a dropper added with the package so that one may fill the rotating boiler as the hole is very narrow.
Students construct water-propelled engines from soft drink cans. They test the engines and the variables that affect the action-reaction of the engines.

When I want hard boiled eggs, I boil them in a pressure cooker. If you haven't tried cooking eggs this way, you're missing out. The other morning, to help cool the eggs faster and to speed up releasing the pressure from the cooker, I removed the little pressure regulator on top of the cooker so I could safely open it to remove the eggs. Watching the steam and hot air shoot toward the ceiling, it also reminded me of seeing a Hero's Engine design once when I was interested in Stirling Engines. For about 2 or 3 years now, I've wanted to build a Hero's Engine.
