- Team of scientists from the University of Hong Kong have developed, and are patenting a technology for recovering electricity from low grade heat.
- This type of heat is abundant, and available all around us, and a lot of it is essentially waste energy generated during industrial processes and energy consumption.
- The new device, DTCC, is a bendable, stackable and low cost cell with graphene and polyaniline electrodes.
- With 3.5% conversion efficiency, the device is better than any other thermo-electrochemical or thermo-electric system.
- The team established a start-up to commercialize the technology.
- Tech giants, including Google, are fighting with Internet Service Providers over all of the internet users’ rights to a secure DNS.
- The DNS is the first step in connecting a user to the website she wants to view, and it’s also the least secure step, where ISP’s can easily spy on their users.
- Google and Firefox are advocating that users should be able to at least choose a secure DNS, but the ultimate goal is to make it the standard.
- Using an intriguing new process, scientists can now create real gold with different material properties.
- They do this by embedding gold nanocrystals in a mesh of protein fibers and plastic, resulting in 18-karat gold that weighs around 5 to 10 times less than standard gold.
- It can be worked just like real gold, and used in jewellery as well as industrial applications.
- The material can also be customized to have different characteristics by changing the composition, and replacing the type of plastic used as the base.
- Financial institutions in India are rolling out data protection systems that aim to give consumers and businesses complete control over their financial data.
- Essentially, one will have a joint account that accumulates all of one’s financial info, and will be able to choose which data to share with an institution.
- Whereas in the West, it’s the other way around - we don’t know how much, or what kind of data institutions have about us, and we can’t control how they use it.
- The main challenge in introducing the system will be to help Indians understand it, as much of the population is poorly educated.
- Study finds causal relationship between psychedelic use and increased nature-relatedness.
- In other words, we appreciate nature more after we use psychedelics.
- It’s not the only way to get closer to nature, going out on a hike might be enough for most people.
- However, the finding does prove that psychedelics have a positive effect on our psychological wellbeing.
