100 times stronger than steel yet 4 times lighter. Conductive and biocompatible. Carbon nanotubes (CNT) are fascinating materials that could channel a kaleidoscope of futuristic technologies around sustainability. They could be a key to the zero-carbon energy future transition. While these graphene tiny tubes have been overhyped as revolutionary for about 30 years, they haven’t made it to the market yet. But we’re seeing slow progress towards interesting use cases, like a recent advancement that could turn carbon nanotubes into hot stuff for generating clean renewable electricity out of waste heat. Let’s revisit carbon nanotubes and see how things are shaping up.
Why 3D Printing Batteries Matters
Renews automatically, cancel anytime. Terms apply. 3D printing has become popular with manufacturers since it provides flexible design, rapid prototyping, cost-effectiveness, waste reduction, and a way to increase sustainability in manufacturing. We’re used to seeing 3D printed toys, shoes, tools, and now even 3D printed homes, which I’ve explored in a previous video. But what if we could 3D print solid-state batteries? Could this really work and be viable? Let’s explore how 3D printing may be helping to drive sustainability and make solid state battery technology more affordable.
Is the Power Grid Ready for Green Energy?
Despite the rise of renewable energy, the backbone of the power grid is fossil fuels. Adapting the grid to green energy sources is more complicated than flipping a switch.
Lithium for EV Batteries Is in High Demand, but Protesters Push Back | WSJ
Lithium prices are rising as demand for the key ingredient in electric car batteries grows, amid a broader push to move away from oil and gas. But the extraction of the metal is time-consuming and potentially harmful to the environment, and plans to produce more have prompted protests.
How Electricity Generation Really Works
The importance of electricity in our modern world can hardly be overstated. What was a luxury a hundred years ago is now a critical component to the safety, prosperity, and well-being of nearly everyone. Generation is the first step electricity takes on its journey through the power grid, the gigantic machine that delivers energy to millions of people day in and day out. So how does it work?
Capacitors Are Gaps! How Does That Work?!
Capacitors are tiny physical gaps in a circuit. How does that even work? Well, if we analyze capacitors on a deep level, we see they’re almost breathing energy.
This Solar Powered Boat Could be the Future of Transportation
Costs for solar panel systems have been dropping at a blistering pace in the last few years and are being widely used as a clean alternative to fossil fuels. Solar panels for home work great, as well as the solar RV and even some solar powered cars … but what about solar boats and solar yachts? Can solar power be a feasible resource to power yachts, boats and ferries?
Green energy: Which sources are the most sustainable? | The Economist
Fossil fuels still supply about 80% of the world’s power. How can energy be produced and used more sustainably to meet climate targets? We answer your questions.
Electric Potential Difference | Electricity
Given just a copper wire, do you think electricity will flow through it? Or do we need a factor that triggers the flow of electricity? What is that factor? What is the Electric Potential Difference?
Revisiting the Supercapacitor – The Wait for Graphene is Over
There’s been lot of hype about graphene since it was first discovered and called a breakthrough. But we’re still waiting for the next big thing. That’s starting to change. A newly announced supercapacitor from Skeleton Technologies could make a big impact on the renewable energy market. Let’s revisit graphene, the supercapacitor, ultracapacitor, how it compares to lithium ion batteries, and when and where it’s going to start making an impact.
