What Will Happen to the Sun?

Posted by in category: energy

Billions of years from now, the Sun’s finale will turn the entire inner solar system into a very nasty place.


The Sun is an ordinary star. It bathes the solar system with light and heat, making life possible on Earth. It’s as regular as clockwork, and it sets our daily life cycles in conjunction with Earth’s spin. Little wonder ancient peoples revered the Sun as a god. Yet the Sun will not always be steady and reliable. Billions of years from now, the Sun’s finale will turn Earth — and the entire inner solar system — into a very nasty place.

At 4.6 billion years old, the Sun is about halfway through its life. Its adulthood, called the main sequence phase, lasts 10 billion years. When the Sun runs out of hydrogen fuel, it must generate energy by fusing heavier elements.

Are 3D-Printed Schools a Solution to Africa’s Classroom Shortage?

Posted by in categories: education, energy, finance

Olipa Elisa said her 10-year-old son used to have to hike 5km (3 miles) every day to the nearest school, often arriving late and exhausted.

“I am very excited that we now have a school closer to my home, and my child will not have to take the long journey,” said Elisa, 38. “What we need is more of these learning blocks to accommodate other classes.”

Run by 14Trees, a joint venture between Swiss cement manufacturer LafargeHolcim and British development finance agency CDC Group, the project was faster, cheaper and less energy-intensive than conventional construction, said 14Trees managing director Francois Perrot.

Bio-inspired ceramic–metal composite stands its ground against cutting tools

Posted by in categories: energy, materials

Circa 2020


Harnessing the destructive potential of force and rotation, cutting tools like saws, drills, and angle grinders can obliterate the superlative properties that materials work so hard to perfect. And even when materials are designed to work against the power of these tools, the materials still often fail.

Sweden Pushes For Real Green Steel

Posted by in categories: energy, sustainability

HYBRIT and H2 Green Steel have launched projects in Sweden with a target to manufacture 10 million tonnes (mt) of fossil fuel-free crude (green) steel per year by 2030. Success, of course, depends on the numbers adding up, or rather, the numbers going down.

To make green steel, you need green hydrogen; to make green hydrogen, you need cheap renewable energy. HYBRIT and H2 Green Steel believe this will come from wind power at a LCOE of $30 per megawatt-hour. With the trajectory of costs for renewable energy going ever downward, it is likely they will be able to achieve this.

Add to the mix the increasing costs of carbon and the pressure to decarbonize, and you have a winner. It is expected that a carbon credits will be available to green steel producers of around $85 per ton.

How Hydrogen Could Solve the Energy Crisis: Bloomberg Green

Posted by in category: energy

Hydrogen is the simplest element in the universe. And excitement is growing from nations and investors looking to harness its power to make clean, green energy. In this edition of Bloomberg Green, we speak to Australian billionaire Andrew Forrest about his big pivot from dirty coal to clean hydrogen. And Snam CEO Marco Alvera talks to us about his price target for the gas over the next decade. Plus, we break down the difference between gray, blue and green hydrogen, and speak to our BloombergNEF analysts about the possible limitations of the gas.
