High-tech and highly efficient batteries have led to many modern technologies that you use in your everyday life. Here's what you need to know about how they work and their environmental safety.
economists typically prescribe liberalising reforms of the sort that have been advanced by the IMF and the World Bank since the 1980s under the label of the “Washington Consensus”. Among the most widely adopted are sober fiscal policies and steady exchange rates. Today technocrats urge looser ...
For most developing countries, low-tech production sectors have always been an inevitable stage of development. Yet the development of those industries is typically accompanied by high levels of pollution -- much like the early period of industrialization in the United States and other Western countri...
In recent years, China's booming exports of the "new three" speaks volumes. The three major tech-intensive green products -- solar batteries, lithium-ion batteries and electric vehicles -- stand as an eloquent testimony to China's manufacturing prowess and strong presence in global supply chains...
Right now, Chinese firms are the most likely to invest in lithium acquisitions, because their capital costs are much lower and they are much more vertically integrated than Western players – while multinationals are more likely to develop their own assets rather than being perceived to buy existin...
But even within the United States, there are some states and regions that don't contain enough water to supply their populations. Coastal regions of Florida have so much saltwater that they must have freshwater piped in from inland areas, which has led to political disputes over control of ...
the really difficult inventions are the physical and chemical ones. They mean bigger risks. They may be losing out because hardware is hard. It's much harder to scale up a physical or chemical invention than it is a software based invention. Think of batteries. Lithium-ion batteries in porta...
The tiger shark 7 (consider) to be one of the most dangerous sharks in the world. Why are tiger sharks so dangerous? First, they like to live 8 waters where humans usually swim, so the chances of an encounter ( 遭遇 ) are much greater. Second, tiger sharks are so strong and aggressi...
In other words, the person doesn't eat much. Oh, how false! Birds actually consume a wide array of insects, nectar and other goodies, noshing frequently throughout the day. It may seem like they're not eating much because they eat a small amount at a time, but they are: Some insect...
A much newer approach to the Earth battery uses soil as a more active player in producing electricity. In the case of the microbial fuel cell, it's what's in the dirt that counts. Microbial-battery Lamp It only takes a small amount of power to run a light or charge a cell phone....
