Thanks for your observation and question about the undulated shape of the runway visible at 2:20 in the video. That wavy or undulated appearance is actually an intentional design feature to mainly facilitate drainage. You're right, some runways do have those subtle ups and downs, and here are a couple of reasons for it: 1. Drainage: A key function is to ensure proper water drainage from the runway surface. These gentle slopes, similar to vertical curves on roads, minimize rainwater sheet flow down the runway where traverse grooves channel rainwater away from the runway center towards the sides where it can be collected by drains. This prevents water from pooling on the runway which could lead to hydroplaning for landing and taking off aircraft. 2. Longitudinal Grade: Another reason is related to the overall slope of the runway, called the longitudinal grade. Runways aren't perfectly flat; they may have a slight incline to aid in aircraft takeoff or landing depending on the surrounding terrain. These subtle undulations can help smooth out the transition between the flat runway surface and the longitudinal grade. The exact design of these undulations considers factors like the type of aircraft using the runway, the amount of rainfall expected in the area, and the overall topography of the airport. Let me know if you need any clarification or have additional questions!

@@steventheengineer Thank you very much for the clear answer!

I appreciate your perspective on wanting to see vertical farming applied to staple crops like corn and wheat, rather than just leafy greens and vegetables. You raise a fair point - for vertical farming to truly revolutionize agriculture, it needs to tackle large-scale cultivation of major grains and cereals that feed our growing global population. While the current focus has been on optimizing vertical farms for produce like lettuce and herbs, research is ongoing to adapt the technology for broader crop varieties. Factors like lighting requirements, growth cycles, and space utilization need to be fine-tuned. However, the core benefits of vertical farming, such as reduced water usage, year-round production, and localized food sources, hold true regardless of the crop. Regarding your point about energy efficiency, you're correct that traditional open-field agriculture relies on free sunlight. However, vertical farms aim to offset their energy needs through sustainable design, renewable energy sources, and technological advancements in lighting and climate control systems. The goal is to strike a balance between minimizing environmental impact and maximizing crop yields in urban areas. Rest assured, the agricultural industry recognizes the importance of scaling up vertical farming for staple crops. It's an exciting frontier that researchers and innovators are actively exploring. I'll be sure to cover these developments in future videos as the technology evolves. Thank you for raising this insightful point - it will help drive the conversation forward.

Thank you for your insightful comments and suggestions regarding the design of the proposed Shimizu Mega-City Pyramid. You've raised some excellent points that are worth considering. Pyramid vs. Triangular Shape: The pyramid shape was likely chosen for its inherent stability and ability to distribute weight evenly. However, your suggestion of a steeper triangular shape with attaching structures is intriguing and could potentially offer more surface area and versatility. Cables and Support: You make a valid observation about the lack of visible cables or supporting structures in the concept renderings. Additional reinforcement, perhaps through tensile cables or external bracing, could enhance the structural integrity of such a massive floating structure. Base Material: Your recommendation of a cement-urethane-graphene rubber base is interesting. Composite materials like these could potentially provide the necessary buoyancy, durability, and strength required for the base of a floating city. Column Design: Wide, sealed columns could indeed offer improved stability and load-bearing capacity, especially in a floating environment where buoyancy and displacement are critical factors. These are all excellent points that highlight the importance of thorough engineering and material science considerations for such an ambitious project. While the Shimizu Mega-City Pyramid is still a conceptual idea, your feedback underscores the need for rigorous analysis and innovative solutions to address the unique challenges of constructing a floating metropolis. Thank you for engaging with the video and sharing your valuable insights. As this concept continues to evolve, incorporating perspectives from various fields will be crucial in refining the design and ensuring its feasibility and sustainability.

Hi Mr. Ryesky. It's great to hear from you. Thank you for sharing your insights and experience regarding bamboo. You raise a valid point about the need for careful consideration when planting bamboo near infrastructure. While bamboo can indeed be an incredibly versatile and sustainable material for various applications, including textiles, you're absolutely right that its aggressive rhizome root system can potentially cause damage if not properly contained. Thank you for enriching the discussion with your personal experience and raising awareness about the importance of thoughtful planning when incorporating bamboo into our lives and surroundings. Insights like yours contribute to a more well-rounded understanding of sustainable living.

Great question! While artificial intelligence is certainly revolutionizing many areas of structural engineering and architecture, at this point I think it’s more likely to become a powerful design aid TO civil and structural engineers rather than fully replace them. Complex problem-solving around structural integrity, materials, constructability, human safety, and translating concepts into physical reality still requires a level of human ingenuity and oversight. However, AI is proving incredibly valuable for optimizing and generating design options, spotting potential failure points, mining data to inform decisions, taking over repetitive tasks, and keeping up with constantly evolving building codes. It’s an exciting complement underway! My video explores a number of the key ways AI is transforming the field. But for many of the reasons above, I believe structured engineering roles are more likely to be “augmented” by AI capabilities rather than made obsolete. Curious to hear your thoughts on how you see the technology impacting structure and infrastructure design down the road! Let me know.

@@steventheengineer Thank you sir for your kind information

I'm intrigued by your strong endorsement of hydroponically grown tomatoes! You seem to really prefer the taste compared to tomatoes grown in soil. I'm curious what specific qualities make the flavor so noticeably better from your perspective? With the ability to closely control nutrients and cultivation conditions, I can see how hydroponics could potentially optimize certain flavors and textures. But I'd love to hear your first-hand impressions. How would you describe the difference? Have you noticed similar improvements in the taste or quality of other hydroponically grown produce compared to traditional farming methods? I didn't dive too deep into consumer flavor differences in my video, so very interested to gain insight from your actual experiences eating this kind of produce. Appreciate you taking the time to watch and comment!
