2040 – Official Trailer

– My name is Damon, and this is my daughter, Velvet. Her major concern right now is the elusive art of sleep direction. But soon, she’ll have to face a rapidly deteriorating environment. – The ice sheet is now melting faster than the scientists predicted. – I think there’s room for a different story, a […]

Biodiesel: The afterlife of oil – Natascia Radice

Just a minute ago, this oil helped make a delicious meal possible. But now, it’s just some nasty goop. What should we do with it? Well, the easiest thing would be to pour it down the drain; that makes it seem like it’s gone, but it’s not really gone. Instead, it’s collecting bits of food […]

Cheaper and greener electricity at home

Our days are regulated by the use of appliances that weigh on our electricity bills. But machines like air conditioning, water boilers or refrigerators could be less expensive if used in a clever way. To help us save money, experts from the EU-funded project ADDRESS have developed this Energy Box, currently tested by Spanish households. […]

1. Advance Illustration | Current Electricity | Resistance of a Conductor with Varying Cross-Section

here in this illustration, we’ll discuss about the resistance of a conductor with varying cross section. here you can see the figure shows a conductor of length l. and having a cross section which is varying. and, the radius of cross section varies linearly from, radius ay to b. and the resistivity of material given […]

Big eco friendly fridge can store three people. Uses no electricity!

Franz, can you tell us something about this eco-friendly fridge? I’d love to. First, I want to welcome you to Quinta Das Pedras Alvas. Which is our place here in Central Portugal. The summer can be very hot here. Like many places in Portugal. So a fridge is definitely something you want to have. You […]

Chemical engineers’ research may lead to inexpensive, flexible solar cells.

We are working on controlling the microstructure on polymers on the nanometer level in order to create functional device — things that can, for example, generate electricity from sunlight. So our efforts are really focused on being able to develop a new class of, for example, solar cells or photovoltaic devices where we can utilize […]

14. Class 12th Physics | Current Electricity | Experimental Verification of Ohm’s Law | Ashish Arora

let us discuss the experimental verification of ohms law. and by ohms law. we know well that current in a resistance can be directly given as v by r. and just to verify this experimentally lets have a look on the, circuit diagram which we can see here in the figure. you can see there […]

Electricity generating textiles

I’m Anja Lund, I’m a researcher at Chalmers University of Technology. My topic is electronic textiles. This means that I mainly develop textile fibers that can conduct electricity and also fibers that can generate electricity. Most people have an idea of what textiles are. We all have textiles around us every day. But I think […]

Brookfield Renewable – Welcome to the Global Renewable Hub

The world’s most influential companies are committed to 100% clean energy you too can make a commitment to change the future private businesses account for around half of the world’s electricity consumption business leaders know that committing to renewable power will accelerate the adoption of green energy and the decarbonisation of our planet here the […]

Solar Cell Research: Letian Dou

My name is Letian Dou. I’m an assistant professor in Chemical Engineering at Purdue University. My research is on solar energy materials and electronics materials. When I was a child, I grew up in China. There was a lot of power shortage and during the night there is no light. We cannot read. We cannot […]
