This device combines solar and human energy to generate electricity
An average person creates 100 to 150 watts of power while riding a stationary bike. That energy, however, usually remains untapped, causing users to miss out on a great opportunity to generate their own green electricity. In fact, by harnessing the biomechanical power generated by a stationary Read More...
This smart wheelchair enables users to climb stairs and adjust height

That’s why we’re happy to share with you BRO, a futuristic, stairs-climbing wheelchair developed by Scewo, which aims to offer people of restricted mobility the Read More...
You will soon be able to feed your cat lab-grown mouse-meat snacks
Most of the food that we feed or pet cats and dogs is meat-based which, as you can imagine, has its negative impacts on the environment. In fact, producing meat for our cats and dogs has a footprint of about 64 million tons of carbon emissions — that’s more than a quarter of the environmental Read More...
This 3D-printed glioblastoma tumor is the first of its kind
Researchers at Tel Aviv University (TAU) have accomplished an impressive feat: they are the first to 3D print an active glioblastoma tumor in a brain-like environment, complete with blood vessels supplying the mass. It’s the most comprehensive replication of a tumor and surrounding tissue to date Read More...
New tidal energy design harvests double the energy from ocean waves
Tidal energy could soon hit record conversion efficiency thanks to a new development from scientists at Australia’s RMIT. The engineers have developed a novel design for a convertor that they claim operates with far greater efficiency than current systems. They hope the breakthrough could pave Read More...
Four strategies to make solar panels even more sustainable
Solar energy is a renewable source with fairly high reliability and scalability, but even the best solutions have some drawbacks. In the case of solar, the panels themselves are emissions-intensive to produce and require mined silicon, glass, and aluminum. As we continue to improve the Read More...
These green SUP boards are made from retired turbine blades
Many surfers, divers, and others ocean lovers hold a strong desire to protect our marine environments from pollution and warming. However, some of the equipment these ocean enthusiasts use are not made of sustainable or eco-friendly substances. For instance, stand-up paddleboards, while Read More...
The Ocean Cleanup deploys largest trash-collecting system thus far
Since it first undertook the daunting task of ridding our oceans of plastic debris in 2013, The Ocean Cleanup has made numerous tweaks to its trash-catching barrier system — and the latest one may be the most important yet. The most recent update involves an active propulsion system rather than Read More...
Can't stand the heat? This new fabric will cool wearers down
Let’s face it—it’s getting pretty hot out here, and we’re going to have to adapt to these warming temperatures. Luckily, engineers Ma Yaoguang and Tao Guangming, from Zhejiang University and Huazhong University of Science and Technology respectively, have invented a textile that cools Read More...
The world’s first all-electric tugboat to put to sea in 2023
According to the International Maritime Organization (IMO), maritime transport emits around 940 million tonnes of CO2 annually and is responsible for about 2.5 percent of global greenhouse gas (GHG) emissions. As engineers are working to green up cargo ships with the help of low-carbon fuels, Read More...
