Startup makes residential solar panels twice as efficient
With a 36% yield, the solar panels developed by startup Insolight could deliver up to twice as much energy as traditional panels. The company came up with a thin structure that directs the sun’s rays to the small surface area of very high performance solar cells. The result is a highly efficient flat photovoltaic system.
What vapour? The effectiveness of O-rings, seals and mastic
Doing a great job at keeping out water, greases or liquid, O-rings, gaskets and seals do sometimes however have such low vapour resistance that gasses, such as water vapour, can pass through them virtually unhindered (e.g cellulose, EVOH or PVOH). This dramatically reduces their effectiveness.
Oxygen found in exceedingly distant galaxy
Using the giant ALMA telescope in Chile, astronomers in Japan, the UK, Sweden and Germany have found oxygen in an extremely distant galaxy – farther away than oxygen has ever been found before. The finding opens the door to methods of studying galaxies in the universe’s childhood and provides a key to unravelling this enigmatic epoch of the universe’s history when the gas between the galaxies shifted from being neutral to being ...
NASA tests new insulation for SLS rocket
You may not think about insulation much, but it's one of those unsung industry heroes that keeps our drinks cold and homes warm on those bone-chilling winter days. Insulation also is a key component to protecting NASA's Space Launch System and its super-cold fuels for the journey to Mars.
Catalyst to be used in renewable fuels production
Researchers at Stanford University and the Department of Energy's SLAC National Accelerator Laboratory have developed a tough new catalyst that carries out a solar-powered reaction 100 times faster than ever before, works better as time goes on and stands up to acid.
Subatomic microscopy key to building materials
Researchers at Penn State and the Molecular Foundry at Lawrence Berkeley National Laboratory are pushing the limits of electron microscopy into the tens of picometre scale, a fraction of the size of a hydrogen atom.The ability to see at this subatomic level is crucial for designing new materials with unprecedented properties, such as materials that transition from metals to semiconductors or that exhibit superconductivity.
MIT evaluation and report of water test kits
How do you know your water is clean and safe to drink? Whether you live in Flint, Michigan, or a half a world away in northwest India, many families don’t have a good answer to this question.People use countless methods to clean their water — from purchasing filters and purification products, to boiling water on a stovetop, to relying on their local governments to guarantee tap water safety.
Smart Urban Mobility Show to run alongside All-Energy 2017
The SUMS (Smart Urban Mobility Solutions) exhibition and conference will be co-located with the UK’s largest renewable and low carbon energy exhibition and conference - All-Energy2017 (SECC, Glasgow; 10-11 May 2017). The new event will focus on Glasgow’s pioneering work on smart citiesand the city’s, and Scotland’s, long history of innovation in intelligent traffic control.
Converting gaseous carbon dioxide to fuel
A team of scientists from the University of Toronto believes they've found a way to convert carbon dioxide emissions into energy-rich fuel in a carbon-neutral cycle that uses a very abundant natural resource: silicon. Silicon, readily available in sand, is the seventh most-abundant element in the universe and the second most-abundant element in the earth's crust.
A low-cost solution for storing solar energy
How can we store solar energy for period when the sun doesn't shine? One solution is to convert it into hydrogen through water electrolysis. The idea is to use the electrical current produced by a solar panel to 'split' water molecules into hydrogen and oxygen. Clean hydrogen can then be stored away for future use to produce electricity on demand, or even as a fuel. But this is where things get complicated.
