The largest volumes of methane on Earth are frozen deep underground. Learn how global warming could melt these stores and start the irreversible process predicted by the Clathrate Gun Hypothesis. Earth Science - Human Impacts - Learning...

The discovery and uses of reactive metals throughout history, and how their uses have defined the period in which they were discovered. Chemistry - Periodic Table - Learning Points. The reactivity series ranks the chemical reactivity of...

We compare melting points of lead and tin to the melting point of their alloy, solder. By timing how long it takes samples of each to melt, we discover that the melting point of solder is actually lower than those of both lead and tin....

We use a metal ball and hoop to demonstrate heat expansion. When cool, the ball fits through the hoop, but there is little extra space. The ball is then heated over a Bunsen burner. When hot, the ball doesn't fit through the hoop. We see...

Salt is found in the oceans and Earth's surface. How do we collect this salt and separate it from the materials it is mixed with? Chemistry - Atoms And Bonding - Learning Points. Salt is found in oceans, lakes and underground rock beds....

Today, we're going to uncover the shocking truth about air pollution and its impact on our lives. In this video, you'll learn about the hidden dangers that air pollution poses to our health, the environment, and the steps we can take to...

Uncover the fascinating world of animal-derived energy solutions, from cows powering farms through methane production to microorganisms illuminating buildings. This video showcases how bioluminescence and anaerobic digestion are...

Dive into the craft of knife making, tracing its roots from medieval blacksmiths to today's high-tech forges. Discover how the choice of materials and methods like quenching have evolved to produce blades that are both sharp and...

You may have heard of nano-robots, but are these really “robots” (like Transformers), or are they something completely different? Professor Stoyan Smoukov shows us how nano-scale devices can be easily ‘grown’ from simple sources and how...

UniverCity introduced the "Verdant" building, offering units at 20% below market value with the condition that resales maintain this discount, allowing residents to benefit from market increases while keeping housing affordable....

Explore a yurt-inspired home, featuring a green roof that enhances biodiversity, provides acoustic and thermal insulation, and mitigates environmental impact. The roof, along with solar panels and a rainwater collector, reflects their...

The transcript discusses the increasing emphasis on sustainable architecture in response to . Interest in eco-housing and sustainable architecture has been growing as global warming and resource depletion increase. This video showcases...

The construction of the Woodcube, a sustainable housing development in Wilhelmsburg, required ten days of preparation in the Black Forest and fourteen days for on-site assembly. Financially, the building proved more cost-effective than...

The Rehafutur project in Loos-en-Gohelle involves renovating a 300 square meter UNESCO heritage building to achieve high energy performance while preserving its industrial heritage. The project uses state-of-the-art ecological...

The "25 Verde" building in Turin, Italy integrates bio-climatic architecture and advanced technological tools, such as a restored geothermal unit, to minimize energy consumption. This system efficiently provides hot water, heating, and...

In designing a sustainable building, Luciano Pia prioritized minimizing resource usage. He used untreated materials like Corten steel and larch wood, allowing them to develop a natural patina over time. The "25 Verde" building features...

Soon after moving to Isle of Eigg, Neil Robertson adapted his home to align with the island's sustainability policies by using solar panels, a wood-burning stove, and electric immersion for hot water and heating. He and his wife...

The video explores the history and advancements of biofuel technology, showcasing how cities like Vaxio in Sweden have successfully transitioned to renewable energy sources to combat climate change. Researchers are developing innovative...
