Collaborate Disseminate
As any programmer could tell you, there’s significant value in automating a process that is performed often enough. The more times that process is used, the more it makes sense to automate it or at least improve its efficiency. This rule isn’t limited to software though; improvements to hardware design …read more
Researchers at Aalto University have developed a photovoltaic device that has an external quantum efficiency of 132 percent. This impossible-sounding feat was achieved using nanostructured black silicon, and could represent a major breakthrough for solar cells and other photodetectors.

Perovskite is quickly emerging as a frontrunner for more efficient solar cells, but it has one major problem – it’s a bit too fragile. Now, a team of engineers led by Purdue University has found that adding one bulky molecule can stabilize the material… Continue reading Bulky molecule makes more stable perovskite solar cells
Solar cells are constantly improving on the road to maximum efficiency. Now, three records have been broken by two different devices, including one that pushes the highest overall solar conversion efficiency towards the 50-percent mark.Continue Reading… Continue reading Two new solar cells break records, including highest efficiency ever
In the ebike world, there are two paths. The first is a homemade kit bike with motors and controllers from China. The second is a prebuilt bike from a manufacturer like Giant, with motors and controllers from China, which will be half as fast and cost three times as much. …read more
One of the current hype trends is the supposedly imminent revolution in air transport. So many companies showing digital renderings and mockups to illustrate their own utopic vision for the future, reaching fevered pitch at events like CES 2020. But aviation has a long history of machinery that turned out …read more

Once a program has been debugged and works properly, it might be time to start optimizing it. A common way of doing this is a method called profiling – watching a program execute and counting the amount of computing time each step in the program takes. This is all well …read more

Once a year, the Delsbo Electric contest in Sweden challenges students to create and improve on the world’s most energy-efficient vehicles. This year’s champ, the Eximus IV, smashed the competition and all previous records with an electric equivalent of 687 MPGe (0.34 l/100km).

It’s been forty years since the infamous Three Mile Island accident, an incident made famous bythe confusion and panic it spawned in its wake. But while the incident is remembered for the fear it stoked about nuclear energy, it also set the stage… Continue reading The Nuclear Industry and Communication: Lessons from Three Mile Island
While we often think we are clever designers, living things often meet or beat the best human designs. It is easy to forget that nature even has living lightbulbs, among them the firefly. Researchers from Penn State decided to compare how fireflies create light and found that they deal with …read more
