Transportation has always been a important and one of the fundamental aspect of human development. The connectivity and the time saved due to transportation can never be replaced. But with the increase in pollution and decrease in the fossil fuels has lead the researchers to find a more renewable and environment friendly fuel that could be used to power vehicles. To this frontier California-based car company, Faraday Future, just unveiled a new, fully electric concept car that can boasts 1,000 horsepower, top speeds of over 200 mph (321km) and can go from 0-60 miles (94.5 km) in under 3 seconds. WOW that’s fast…

Engineering professionals are often faced with a problem or a predicament requiring thorough planning, designing, verification and implementation. Those steps can be accompanied by a techno-economic study, calculations on the total cost of ownership (TCO) and a schedule for return on investment (ROI). Sounds familiar? Sounds like some of the phases and building blocks of a somewhat typical engineering predicament. The predicament, not in a negative way, but in a challenging sense that something needs to be solved fundamentally by means of engineering.

The first thought that comes to one’s mind is of Marty McFly’s self-lacing Mag high-top sneakers from Back to the Future II when they think of futuristic footwear, but latest developments in flexible electronics changes all of that. Whilst the ShiftWear sneakers may be inconvenient to you with lace-tying, their integrated, flexible panels are meant to offer an open canvas so that your feet can match attire, mood or season. The specialty being able to power the sneakers on and select design from the mobile app.

Each pair of ShiftWear sneakers features always-on E Ink displays, similar to those found in e-readers. The built-in batteries are designed to last up to 30 days, depending on the type of visuals set. The Static images consume little-to-no power, while animated graphics are expected to drain batteries much faster, especially with increased complexity or frequency. The team developing these kicks plans to incorporate wireless charging capabilities, as well as “Walk-N-Charge” technology that let the shoes charge up with every single step.

“Nature knows how to make these materials and stay environmentally friendly, Our job has been to figure out how and why, and to emulate that. In the lotus leaf, these are due to papillae within the epidermis and epicuticular waxes on top, In our material, there is a micro structure created by the agglomeration of alumina nano particles mimicking the papillae and the hyper branched organic moieties simulating the effect of the epicuticular waxes. The textured surfaces of other super hydrophobic coatings are often damaged and thus reduce the hydrophobic nature, our material has a more random hierarchical structure that can sustain damage and maintain its effects.”

An international team of scientists has come up with a new type of energy system they’re calling ‘hydricity’, which combines the power of sunlight with hydrogen fuel to produce a cleaner and renewable source of power. In a post researchers say:

“By combining both solar thermal power plants with hydrogen fuel production facilities efficiency in both types of power could be improved. An integrated system would produce both steam for generating electricity immediately, and hydrogen for storing it for later use which is a crucial consideration as the world become more dependent on renewable energy”. The scientists have so far only produced simulated models of the process. The next step is real-world experiments. The team, from Purdue University and Switzerland’s Federal Polytechnic School of Lausanne, says that it can produce hydrogen at an efficiency of 50 percent and electricity at an efficiency of 46 percent which is way greater than any solar plant producing. It was all possible because of the way the high-pressure turbines can be used to run in succession of the lower-pressure ones. Over the course of an average 24-hour trail, it’s claimed that hydricity could reach a Sun-to-electricity efficiency of 35 percent, which is as good as the best multi junction photo voltaic cells combined with battery power.

“If we could all afford a really expensive tutor who could spend time thinking about what you should learn. Our intuition tells us if you pay enough attention to what a student did as they were learning, you wouldn’t need to have them sit down and do a test.” Well that’s not realistic, but educational institutes could one day just use this type of software to pinpoint where someone is struggling and help them improve. Eventually, the system could become accurate enough to do away with exams altogether. The dream…..

Humans need of power to grow and develop itself is ever growing and everlasting. The search for renewable source of power has always been a priority for developers. One of the alternative found was solar energy. But as ingenious and environmentally friendly as solar energy solutions are, they’re not as efficient as we wish them to be and of course, they only generate electricity when the Sun is out. There are two ways we get energy from the Sun. One is photo voltaic cells (the panels you see on rooftops) and the other is solar thermal power plants, which concentrate the Sun’s rays and uses it to generate heat to warm up water and drive turbines using the steam that’s produced. The other method is to capture more of the Sun’s solar spectrum, but it is less efficient than a standard solar panel, and can only work in direct sunlight. Which is why we only see them in parts of the world that get plenty of sunlight. As solar energy is not every efficient and can’t be generated in places with no sun it was every important to come up with some other sort of energy. To overcome this problem and to give this world a renewable and clean source of power a team of scientists has come up with a new type of energy system called ‘Hydricity‘.

It is natural in engineering to tackle problems, either given as assignments or found during a common workflow. It is natural for an engineer also to seek problems to solve, even from places where there shouldn’t be any.

Engineering professionals are often faced with a problem or a predicament requiring thorough planning, designing, verification and implementation. Those steps can be accompanied by a techno-economic study, calculations on the total cost of ownership (TCO) and a schedule for return on investment (ROI). Sounds familiar? Sounds like some of the phases and building blocks of a somewhat typical engineering predicament.

Water is one of the greatest treasure of this planet. It is one of the key ingredient that has made life possible on this planet, without it life is not possible. However essential water maybe but no one likes is on their cloths or shoes. Everyone dreams of drenching in rain without their cloths being wet. Well to everyone who every dreamt about it you wish has been fulfilled by researchers from ‘Rice University‘. There’s no doubting that water repellent is a great way to keep clothing, shoes, and all other products safe and dry from water damage, but it involves toxic chemicals that aren’t good for us or the environment. To counter this a new water-repellent coating developed by researchers from Rice University is not only environmentally friendly, but also inexpensive to make. The repellent, consist of a new class of Superhydrophobic nano materials that has been developed taking inspiration from remarkable example of natural water repelling: ‘The Lotus Leaf’. According to the researchers, the lotus leaf’s remarkable ability to repel water is due to its hierarchy of microscopic and nano scale double structures.
