Why do some technologies take off and and others go nowhere?

There are all sorts of reasons if you talk about a specific invention. Everything from the insight of the inventor to grasp the value of what they have invented, to being unable to obtained financing, and on... An invention can be considered to be the exploitation of a technology, or a an exploitation of a technological breakthrough.
If you consider a technology why do specific inventions fail? The base reason is the economic viability. Economic viability can be measured in the following ways, the ability to recoup the costs of making and marketing the invention. The ability to recoup the cost is based on the value of the invention to the end user, either monetarily or in saving of the end users labor (occasionally in entertainment value).
Look at an automobile. Terribly expensive, but I don't have to go out and feed the horse. That makes economic sense, at least to me. (OK a Ferrari would be entertainment, but I don't own one.)
But a couple of fascinating technologies are the steam power and the turbine. The first recorded steam-powered device attributed to an individual, the aeolipile, was described by Hero of Alexandria (Heron) in 1st century Roman Egypt, in his manuscript Spiritalia seu Pneumatica.[1] The Babylonians are sometimes sited as having simple steam devices in about 2000 BC. So was Hero a zero and drop the ball on this invention. No, it was a cool novelty, capable of spinning at 3000 RPM, but the Roman empire ruled the world. It was cheaper to use slaves. There is a very good article on the later economics of steam power at: http://www.statemaster.com/encyclopedia/Steam-engine
1600 years later manpower suddenly came into short supply through hard times and plagues. Suddenly steam became worthwhile. Once some of the details were worked out in several generations of inventions the industrial revolution began.
Today we are still exploiting this technology in steam turbines in nuclear power plants, jet engines, and possible rocket engines. Just add a fer magnets to the aeolipile and it becomes an electric generator. The modern turbine below might be a more efficient version.
