Lamia in this case describes a race of sapient beings who are human from the waist up, and have a snake body from the waist down. If more detail is necessary, their anatomy and physiology would be something similar to that described in this post, though I am not concerned with gritty details beyond the basic premise of having scaled serpent bodies in place of legs, characteristic of the pop culture image of lamia.
In this world, their societies would have developed in a Mesopotamia-like environment, with an extremely arid climate, neighboring deserts and sandswept desert plateau. Initially, their societies would have been river or oasis-based, but expanded as technology developed to make water more portable.
Currently, the world is at a steampunk level of technology, and there is international travel and trade via blimps and the like, so available resources are not an issue. As this is a steampunk world, resources like oil are not readily available, however.
My question is this: what kind of steampunk-era technology would be developed with lamia in mind, that would not be generally useful to any race? I am looking for something that would make a lamia-dominated city stand out in some way from a pure-human city in the same location.
I imagine it would have to be something that specifically offers convenience to their snake halves, in much the same way that a bicycle is specifically a convenience for someone with legs, but I'm not sure what would fit that bill, given the sheer strength and weight of the snake body compared to legs.
