11:46 | A team of researchers in Vienna has shown us how we can reliably move electrons using oxygen as the main source.
How will the next generation of cities address the challenges of climate change?
4:35 | By taking inspiration from ancient cities, the cities of the future can prioritize public transportation and foster human connection, resulting in reduced emissions and more accessibility.
Canada Wildfires Are Caused by Climate Activists!
9:19 | Taking look at a ridiculous video while also explaining some science.
Why is our upper atmosphere cooling?
12:38 | Research now shows that cooling in the upper layers could be jeopardising satellite orbits and opening up a new ozone hole above the arctic. So what’s going on?
In-pipe energy: The hydro power nobody is talking about
9:06 | Around 4% of global electricity is used for providing tap water. That number is only going to increase and its carbon emissions rival that of aviation. But a surprisingly simple idea can make our water supply more sustainable: In-pipe energy.
How Wireless Energy From Space Could Power Everything
10:54 | Electrical engineer Ali Hajimiri explains the principles behind wireless energy transfer and shares his far-out vision for launching flexible solar panels into space in order to collect sunlight, convert it to electrical power and then beam it down to Earth.
Floating cities as an innovative response to climate change
28:25 | Sea levels are rising due to climate change. Many coastal cities are at growing risk of flooding. Architects are trying to react to this development with new ideas, such as floating cities.
Amazon’s black earth. A miracle cure?
13:02 | Terra Preta, or Amazonian Dark Earth, has long been known for its remarkable biodiversity and fertility. Now a new study by a team of scientists in Brazil has identified what it is that makes Terra Preta so special.
The Many Errors of An Inconvenient Truth
22:37 | An Inconvenient Truth is a documentary film from 2006 by Al Gore. The year after it was released it was hauled in front of the UK high court, and found to be riddled with errors. What are these errors, and what can they tell us about climate science?
This 4-minute video got climate “denialists” very excited
13:18 | (and doesn’t say what they think it says!)
This is what’s REALLY holding back wind and solar
11:57 | Building solar farms and wind parks is one thing. Plugging them into the grid is another. How does our power system need to change to cope with more renewables?
The Carbon Footprint Of (Nearly) Everything
4:22 | We decided to put together The Carbon Footprint Of (Nearly) Everything. We hope this helps you understand the emissions you can directly affect through personal choices, and the emissions that you can affect through political and social choices.
