Green Hydrogen Trains from Siemens Energy & Siemens Mobility Source:  Stock Image of Hydrogen Trains Green Sustainable Energy and Green Travel Newly listed on the Frankfurt Stock Exchange, Siemens Energy has signed an MOU (memorandum of understanding) with Siemens Mobility to jointly develop and sell hydrogen systems to power trains.  This is another new and important example of the hot and expansive development of hydrogen fuel cell technology.  The two companies have several goals.   They want to standardize the technology for fully hydrogen powered trains made by Siemens Mobility.  They also want to sell the technology to external companies to promote the "hydrogen economy of Germany and Europe". Smart Green Linkage Siemens Energy is developing green hydrogen, which is produced from renewable sources like wind and solar power.  Siemens Mobility specializes in transportation and is still part of the parent company Siemens.  Siemens Energy wa...

Solar Energy Even on Cloudy Days Source:  Stock Image of Solar Panels Bacteria Powered Solar Cells University of British Columbia scientists have created a low-cost, sustainable way to build a solar cell using bacteria that can harvest light.  What's remarkable is the bacteria can harvest energy from light even on cloudy days. Biogenics Solar cells are the building blocks of solar panels.  They do the work of changing light into electrical current.  The bacteria solar cells are called "biogenic" because they are made of living organisms.  The hope is that biogenic solar cells can become as efficient and even more efficient than synthetic cells used in conventional solar panels. Shedding Light In the past, efforts to build biogenic solar cells have focused on extracting the natural dye that bacteria use for photosynthesis.  That process was costly and complex.  Also it involved toxic solvents that can cause the dye to degrade.
