Yes, the stud on top of your LEGO skyscraper model should indeed be where it is! This clever play on words sets the tone for an interesting exploration of various uses and alternatives to traditional building materials.

Let's dive deeper into some fascinating facts about alternative construction techniques:

1. In developing countries, people often resort to using affordable materials due to limited access to conventional building supplies like bricks and mortar. A cheap yet effective solution is to use compressed earth mixed with a small amount of cement, which can be molded together to create interlocking blocks.

2. Another innovative approach involves utilizing polystyrene foam as the primary material for construction. This method, known as insulated concrete formwork (ICF), involves stacking hollow polystyurye blocks into walls and then filling them with insulating materials such as expanded perlite or vermiculite before pouring in concrete to create a durable structure.

3. However, if you're looking for something truly out-of-the-box - literally! - researchers have been exploring the possibility of using LEGO bricks themselves as building material due to their unique properties like being lightweight yet strong enough support immense weights without breaking under pressure thanks partly because they are made from special type called 'acrylonitrile butadiene styrene' (ABS).

4. Interestingly, if we were able to stack these Lego blocks on top of each other infinitely high without any limits imposed by gravity or physics then theoretically speaking you could potentially build a skyscraper reaching heights approaching 3.5 kilometers into sky! That's equivalent height roughly equaling Eiffel Tower stacked upon itself over thousand times!

However, there are some practical considerations that make using Lego as a large-scale building material impractical at present:

1. The cost: While individual LEGO bricks may seem cheap enough when purchased individually from toy stores - once you factor in the sheer number required to construct even small structures let alone entire skyscrapers made entirely out of them things quickly add up fast becoming prohibitively expensive.

2. Sustainability: Although LEGO bricks themselves are made from plastic which is generally considered more eco-friendly than other materials like concrete; large-scale production still has environmental impact due to resource extraction, transportation etcetera...

3. Durability: While individual LEGO pieces can withstand significant forces before breaking down under stress - when subjected to harsh weather conditions over extended periods of time their structural integrity begins deteriorate leading potential collapse.

So while the idea might seem exciting at first glance; using regular Lego bricks as actual building material remains largely limited to model scale models rather than real-world applications due reasons mentioned above.
