Not all the towers along a transmission line are identical. Look closely at a tower where the line makes a sharp turn and you will likely find it is wider and beefier than other towers along the route. The added strength and weight are needed to resist the unbalanced pull of the conductors, which might overturn an ordinary tower. These special towers are called deviation or angle towers.
The transmission-line tower everybody knows is an Erector Set latticework of steel girders and diagonal braces. The techniques for designing and building these towers are the same ones used in constructing steel bridge trusses or crane booms. The individual pieces can be made cheaply from rolled steel and then bolted together on the site. This last point is more important than it might seem: transporting a fully assembled tower 100 feet tall is an awkward and expensive business.
I’m finding that many people not only have lowered their standards with regard to the user interface, but more and more often when I bring up the subject, they seem to consider it a somewhat secondary aspect, something that’s only good for ‘geek talk’. The same kind of amused reaction laymen have to wine or coffee connoisseurs when they describe flavours and characteristics using specific lingo. Something that makes sense only to wine or coffee geeks but has little to no meaning or impact for the regular person.
The problem is that if an increasing number of people start viewing user interface design as an afterthought, or something that isn’t fundamental to the design of a product or experience — it’s all just ‘geek talk’ — then there is a reduced incentive to care about it on the part of the maker of the product.
