It’s not all upsides, though. The thing about using carbon in a bike is that it makes things incredibly rigid –which is good– but it does introduce some drawbacks. That rigidity allows you to put all the power you can muster into the pedals and eventually the ground, but a...
underlined wo stronger than natural wood and 10 times tougher," said"fracture" in Paragraph 2 mean?Hu, the leader of the team that did the research. “This could be a competitor to steel; it is so strong. It's also A. Make.comparable to carbon fiber, but much less expensive. " B....
根据最后一段中 “The technique could lead to the development of a made-to-last plastic that does not need to be recycled, and can one day be in products from smartphones to cars and even buildings. (该技术可能 导致开发一种不需要回收的经久耐用的塑料,有朝一日可能会出现在从智能手机到汽车...
During composting, microorganisms eat the organic (carbon containing) waste and break it down into its simplest parts. This produces a fiber-rich, carbon-containing humus with inorganic nutrients like nitrogen, phosphorus and potassium. The microorganisms break the material down through aerobic respiratio...
Raw materials are the unprocessed, or minimally processed, inputs used in the production of goods, such as the steel, rubber and plastic used to manufacture cars. What’s more, they are a hot commodity: A forecast from the Institute for Supply Chain Management states that raw material prices...
For most cars, doing all this requires less than 20 horsepower. So, why do you need a car with 200 horsepower? So you can "floor it," which is the only time you use all that power. The rest of the time, you use considerably less power than you have available. ...
Considered futuristic just a few years ago, self-driving cars are on the verge of becoming mainstream. Lower carbon emissions, intelligent roadways, and renewable energy, in part facilitated by IoT, will help to make the planet more sustainable and our lives richer. ...
If you're interested in reducing your carbon footprint and living a more sustainable life, there are countless things you can do to have a positive impact on the planet. One strategy is simply to buy less. And while that's realistic in some cases, the other side of it is making sure ...
Dessau building is seen next to an up-to-date urban mixed-use building. The punch line, of course, is that the two buildings—separated by roughly 100 years—look basically the same, whereas the cars and planes separated by the same timespan seem worlds apart. What is the reason for ...
So…where does sustainability come in? PET is considered a highly recyclable plastic. Used PET containers can be washed and re-melted into plasma, from which new items can be crafted. However, it can be really hard to collect clean, high quality plastics! This means very few PET containers...
