There is something weird about this plot. I think because the calories are normalized to weight and the price is normalized to calories, there is no interesting interaction between the two, looking at it feels like reading a table. You can check which food is expensive and which is calorie dense and that’s it. Perhaps it would be more interesting to look at if both calories and price were normalized to weight…
It is never free to actually capture it, and it usually reduces the efficiency of the process you capture it from. Compare for: turbos use “wasted” positive pressure exhausted from the engine. Sure, but in the process they make it harder for the engine to expel exhaust gases. They can only improve efficiency when done well and at the cost of greatly increased complexity and maintenance needs.
If you install heat capturing, 1) you need to adjust the design of the system to adapt it; 2) you impede the heat dissipation efficiency of the system, which you then need to address with additional engineering. It can be done, but it’s not free, and the math on the costs and benefits doesn’t necessarily come out positive. If there is one thing I trust the industry about: if it can be done to save a buck, they are doing it.
Whoah dude, I don’t know, you’re rapidly saying many numbers without connecting the sentences, what is your point? So either you can get the required chilling capacity using a relatively low amount of electricity, or using a shit ton of captured waste heat. Building a big plant just so you can run a chiller on the waste heat is probably not the most logical path. And now you’re also capturing the heat from power lines or what?
I guess the technology you mention makes sense where a lot of waste heat is consistently available for cheap, thanks for sharing the YSK, moving on.
Compressor chillers with gases like in typical AC have a cop over 3. Why would anyone design district chilling with 3-5 times lower efficiency than that? All that matters is how much energy you spend. Heating that kiln would take more energy if you steal some of the heat for another job, there’s no free energy.
This sounds nice. On iphone, nothing happens when I click your link. When I paste it in safari, it searches for it, and the ddg results are coordinates finder websites, not related to the specific location.
