The Great Pyramid of Giza might be the most iconic structure humans ever built. Ancient civilizations constructed archaeological icons that are a testament to their greatness and persistence. But in some respects, the Great Pyramid stands alone. Of the Seven Wonders of the Ancient World, only the Great Pyramid stands relatively intact.

A team of scientists will use advances in High Energy Physics (HIP) to scan the Great Pyramid of Khufu at Giza with cosmic-ray muons. They want to see deeper into the Great Pyramid than ever before and map its internal structure. The effort is called the Explore the Great Pyramid (EGP) mission.

The Great Pyramid of Giza has stood since the 26th century BC. It’s the tomb of the Pharoah Khufu, also known as Cheops. Construction took about 27 years, and it was built with about 2.3 million blocks of stone—a combination of limestone and granite—weighing in at about 6 million tons. For over 3,800 years, it was the tallest human-made structure in the world. We see now only the underlying core structure of the Great Pyramid. The smooth white limestone casing was removed over time.

Koenigsegg calls the engine the Tiny Friendly Giant, or TFG for short, and it’s an apt name. The TFG is a 2.0-liter twin-turbo three-cylinder that makes 600 horsepower. At 300 horsepower per liter, the TFG’s specific output is far higher than anything ever seen in a road car. Koenigsegg says this is “light-years ahead of any other production three-cylinder today,” and he’s not wrong: The next most powerful triple is the 268-hp engine in the Toyota GR Yaris.

What’s even more unusual is that the TFG doesn’t have a camshaft. Instead, the engine uses technology from Koenigsegg’s sister company, Freevalve, with pneumatic actuators opening and closing each valve independently. I called company founder Christian von Koenigsegg to learn exactly how this unconventional engine works.

The Tiny Friendly Giant was designed specifically for the Gemera. Koenigsegg wanted something compact and lightweight, with big horsepower. Koenigsegg also decided to reverse the setup found in the hybrid Regera, where internal combustion provides the bulk of the total power output. In the Gemera, the majority of the power comes from electric motors, with the Gemera contributing some driving force as well as charging the hybrid drivetrain’s batteries.


The “Tiny Friendly Giant” is a game-changer for internal combustion. Christian von Koenigsegg explains this camless wonder.

We’ve showcased plenty of EV conversions on the channel before, but up until now they’ve mostly been high-end, beautifully refurbished classics. In this episode, Jack heads to France to investigate the entry-level of EV conversion. For €5,000 after government subsidies, a company by the name of Transition One claims it can turn your old banger into a no fuss, no-emissions electric car. Is this the answer to overpriced new cars? Could this be the key to accelerating EV uptake? Check out the episode to find out.

The achievement, published in the peer-reviewed Nature Communication journal today, could see the Morrison government’s so-called hydrogen stretch goal of $2 a kilogram to make the fuel competitive reached as soon as 2025, the Hysata chief executive, Paul Barrett, said.

“We’ve gone from 75% [efficiency] to 95% – it’s really a giant leap for the electrolysis industry,” Barrett said.

Renewable energy from sources such as wind and solar is making big inroads into the power sector, supplying more than a third of eastern Australia’s electricity in the final three months of 2021. However, decarbonising industry and some transport, such as trucking, is likely to be tougher unless fuels such as hydrogen become much cheaper.

While it may be too late for the breakthrough to allow mass adoption for consumer electronics and electric vehicles, Professor Chiang believe it could revolutionise energy storage for large-scale renewable operations.

He has founded a startup, Form Energy, to further develop and commercialise the technology, with the hope of rapidly pushing forward zero carbon energy solutions.

Abundant fuel cell raw materials and renewables potential could add up to a green hydrogen economy in the Philippines, according to Jose Mari Angelo Abeleda Jr and Richard Espiritu, two professors at the University of the Philippines Diliman. In a paper published in this month’s Energy Policy, they explained the country is a latecomer to the sector and should develop basic and applied knowledge for training and research. The country should also establish stronger links between industry and academia, the report’s authors suggested. “The establishment of the Philippine Energy Research and Policy Institute (Perpi) is a move towards the right direction as it will be instrumental in crafting policies and pushing for activities that will usher for more private-academ[ic] partnerships for the development of fuel cell technology in the Philippines,” the scholars wrote. “However, through enabling legislation, a separate and dedicated Hydrogen Research and Development Center (HRDC) will be pivotal in ensuring that sufficient government and private funding are provided.” The authors reported progress in the production of fuel cell membranes but few developments towards large scale production, transport, and storage facilities. “The consolidation of existing renewable energy sources for hydrogen production can also be explored in order to ensure reliable and sustainable hydrogen fuel supply,” they wrote. “This is because the country will gain more benefit if it focuses more on the application of fuel cell technology on rural electrification via renewa[ble] energy-based distributed power generation, rather than on transportation such as fuel cell vehicles.”

Paris-based energy engineering company Technip Energies and Indian energy business Greenko ZeroC Private have signed a memorandum of understanding (MOU) to explore green hydrogen project development opportunities in the refining, petrochemicals, fertilizer, chemical, and power plant sectors in India. “The MOU aims to facilitate active engagement between the teams of Technip Energies in India and Greenko to step up collaborative opportunities on a build-own-operate (BOO) model – in which Greenko will be the BOO operator and owner of the asset and Technip Energies will support with engineering services, integration and EP/EPC [engineering and procurement/engineering, procurement and constructrion] – for pilot and commercial scale green hydrogen and related projects in India in order to offer economically feasible technology solutions to clients,” the French company wrote today.

New battery material offers promise for the development of all-solid batteries.

In the quest for the perfect battery, scientists have two primary goals: create a device that can store a great deal of energy and do it safely. Many batteries contain liquid electrolytes, which are potentially flammable.

As a result, solid-state lithium-ion batteries, which consist of entirely solid components, have become increasingly attractive to scientists because they offer an enticing combination of higher safety and increased energy density — which is how much energy the battery can store for a given volume.

Dubbed Infinity Train, it works by using gravitational energy created on the downhill sections of the rail network to recharge its battery power and eliminate the need for recharging on the return leg of the journey.

The train will allow for a capital-efficient solution for removing diesel and pollutants from Fortescue’s rail operations. It will also help remove the need for the generation of renewable energy as well as the setting up of expensive charging infrastructure.
