Rolls-Royce is Powering the Tempest Fighter Jet

The propulsion design of the Tempest fighter jet will be aerodynamically matched to the air platform, optimising overall performance, range and payload capability.

Rolls-Royce’s optimised Thermal Management System will utilise the gas-turbine as a heat ‘sink’ to recycle thermal energy around the platform. This removes the need for overboard venting and improves overall system efficiency.

Increased electrical power generation capability coupled with an intelligent power management system will meet the growing demand for air vehicle electrical power. This integrated power approach reduces the number of energy exchanges, maximising the potential of the gas-turbine as the primary power source.

Researchers Invent High-Performance Hybrid Solar Energy Converter

Tulane University researchers are part of a team of scientists who have developed a hybrid solar energy converter that generates electricity and steam with high efficiency and low cost.
Matthew Escarra, associate professor of physics and engineering physics at Tulane, and Daniel Codd, associate professor of mechanical engineering at the University of San Diego, are working on the project. Researchers from San Diego State University, Boeing-Spectrolab and Otherlab were also part of the project.
“Thermal energy consumption is a huge piece of the global energy economy – much larger than electricity use. There has been a rising interest in solar combined heat and power systems to deliver both electricity and process heat for zero-net-energy and greenhouse-gas-free development,” said Escarra.
The hybrid converter utilizes an approach that more fully captures the whole spectrum of sunlight. It generates electricity from high efficiency multi-junction solar cells that also redirect infrared rays of sunlight to a thermal receiver, which converts those rays to thermal energy.
The thermal energy can be stored until needed and used to provide heat for a wide range of commercial and industrial uses, such as food processing, chemical production, water treatment, or enhanced oil recovery.
The team reports that the system demonstrated 85.1 percent efficiency, delivered steam at up to 248°C, and is projected to have a system levelized cost of 3 cents (approx Pak Rs. 5) per kilowatt hour.

Electric Car Maker Fisker to Go Public through SPAC Deal at $2.9 Billion Valuation

Electric car maker Fisker will go public through a merger with a blank-check company backed by alternative investment manager Apollo Global Management Inc at a valuation of $2.9 billion.

SPACs have been behind some of the most high-profile public listings of the last 12 months, including electric-vehicle startup Nikola Corp.  Nikola shares are up more than 60% since their debut, and Tesla shares have more than quadrupled this year.

“In electrification, we could have played in buses or trucks, but the car part is a very fast-growing market,” said Geoffrey Strong, chairman and chief executive of Spartan and the co-head of infrastructure and natural resources at Apollo.  “While there is room for several brands, we think that Fisker and Tesla will be at the forefront.”

The Fisker deal, expected to close in the fourth quarter, will provide Fisker with $1 billion in gross proceeds, including $500 million of funds from existing and new investors such as Alliance Bernstein and Black Rock Inc.

Fisker Chief Executive Henrik Fisker, a one-time Aston Martin designer said “We’re obviously very excited about getting full financing all the way to start of production,”

Fisker said the startup is in talks with other companies.  Fisker also is talking with other automakers about using their hardware, including vehicle platforms, motors, battery packs, air conditioning, and other parts, while Fisker focuses on design, software and the consumer digital experience.

Resilience in a Challenging Time

It is truly remarkable how resilient people are when faced with difficult times. In the current environment, it is more important than ever before to stay resilient, stay positive and have the clarity on priorities in our personal life and business needs. Here are a few thoughts I would like to share.

Reflect on what is truly important

As human we always want to be more than ourselves, always want to do more than we can. The current crisis provides an opportunity for us to take the time to reflect on all aspects of our life on how we are spending our time, on the meaning of life, on what is truly important. Our ability to make an impact with our lives often depends on what we decide to prioritize. Likewise, the roles and responsibilities of business leaders have also dramatically changed in the past few months in terms of priorities. Once you are clear on your priorities, you’ll be able to make better and quicker decisions that guide your choices.

  • Do what you know is right at a personal level. It can be through exercise, meditation, or spiritual practices. The simple practice of reading on a daily basis can transform you and have long lasting benefits.
  • Your relationships are your source of happiness and purpose. In a crisis situation, none of us can do it alone. We need people to inspire us so that we can inspire others. We have lesser pains and regrets when we stay with the people we love or care about. Whether it’s family, friends, community, stand by them and take this opportunity to connect with them.

Face the adversity head on and find ways to persevere

It is often said that it’s not what happens to us but how we respond to what happens that makes all the difference in the end. Life is full of ups and downs with huge momentum shifts. This is just how life is, and adversity is a big part of that experience. However, adversity doesn’t need to be a negative experience.

In crisis situation, it is always important to differentiate between what we can control vs what we can’t have influence over. This is not the time to whine and complain about your situation. In fact, the waiting line for gratitude is much shorter than the line for complaint. This is the time to change your story and march on. This is your moment to do something meaningful, to stretch yourself, and to even act out of desperation to make things right.

Be part of the solution by performing civic duty

The best approach we have seen is for everyone to perform individual civic duty by following the recommendation or guidance from medical experts such as social distancing, working from home, and avoiding gathering. Your own behaviour or action is not only responsible for the safety and health of yourself and your family, but also everyone around you. We seem to be willing, somewhat, to do our part only on the brink of catastrophe, rather than willing to change our lifestyle to address tipping points to global crisis. In the end, it will not be the brilliance of scientists, but the collective efforts of everyone doing their part that the world will remember when it looks back at how this crisis was overcome.

Make this a learning moment

“It is only when the tides go out that you discover who’s been swimming naked.” Adversity does not build character; it reveals it. Likewise, pandemic will reveal character and leadership. By and large, human spirit rises up to stare down the crisis.  We should all make this crisis as a teachable moment about the best of people.

This is not the first time and certainly not going to be the last time we face such global challenges. Just think about what difficult time meant for the generations before us who had to go through similar crisis or much worse. The only way for us to get out the current crisis is to come together and join hands. No matter how deep your struggles, no matter the challenges before you, there is sunshine over the mountaintop. And when you get to the other side – and you will – it will be glorious.

Forging High-Tech Armour from Shock-Dispersing Fractal Cubes

Additively manufactured fractal structures with closely spaced vacuums disintegrate shock-waves five times better than solid cubes.

Tiny, 3D printed cubes of plastic, with complex fractal vacuums built into them, have proven to be effective at dispersing shock-waves, potentially leading to new types of lightweight armour and structural materials effective against explosions and impacts.

“The goal of the work is to manipulate the wave interactions resulting from a shock-wave,” said Dana Dattelbaum, a scientist at Los Alamos National Laboratory.

Shock-wave dispersing materials that take advantage of vacuums have been developed in the past, but they typically involved random distributions discovered through trial and error. Precisely controlling the location of holes in a material allows the researchers to design, model, and test structures that perform as designed, in a re-producible way.

The researchers tested their fractal structures by firing an impactor into them at approximately 670 miles per hour. The structured cubes dissipated the shocks five times better than solid cubes of the same material.

Although effective, it’s not clear that the fractal structure is the best shock-dissipating design. The researchers are investigating other void- or interface-based patterns in search of ideal structures to dissipate shocks. New optimization algorithms will guide their work to structures outside of those that consist of regular, repeating structures. Potential applications might include structural supports and protective layers for vehicles, helmets, or other human-wearable protection.

If You Want to Change the World

William H. McRaven, a retired four-star admiral in the US Navy, is one of the most decorated US commanders. He delivered the 2020 MIT commencement speech (virtually) and also the commencement speech for 2014 University of Texas graduation. Both speeches are on similar theme but delivered differently. Both are very relevant to today’s world with the challenges facing all of us, not just the recent graduates. I strongly recommend you spend 15 minutes to listen to his speeches. I promise you won’t be disappointed.

Here are some excerpts from his two speeches.

“Start each day with a task completed. Find someone to help you through life. Respect everyone. Know that life is not fair and that you will fail often. But if you take some risks, step up when the times are toughest, face down the bullies, lift up the downtrodden and never, ever give up — if you do these things, then the next generation and the generations that follow will live in a world far better than the one we have today.”

 “It matters not your gender, your ethnic or religious background, your orientation, or your social status. Our struggles in this world are similar and the lessons to overcome those struggles and to move forward—changing ourselves and the world around us—will apply equally to all.”

 “If you are going to save the world, you will need to be humble. In my career I have been blessed to be around some great minds. I have seen how the brilliant men and women have helped eradicate disease, reduce poverty, create technological masterpieces but, conversely I have seen how the misguided geniuses, filled with conceit and convinced of their own righteousness have tampered with nature, built apocalyptic machines, dehumanized social interaction and tilted toward tyranny. If you do not approach the world with humility, it will find a way to humble you quickly.”

“To save the world, you will have to be men and women of great integrity. Always trying to do what is moral, legal and ethical. It will not be easy and I dare say, you will fail occasionally. You will fail because you are human. You will fail because life often forces you into a seemingly untenable position. You will fail because good and evil are always in conflict.”

“It would be easy to stand up here and tell you that there is wondrous place where you can be great at both work
 and life, where your efforts to make a difference in the world come easy—but I have never found that place. In the end, if your goal is a noble one, then your sacrifice will be worth it. And you will be proud of what you have accomplished.”
