Railroads To Pour Cold Renewable Energy Water On Koch Industries

Posted by in categories: business, chemistry, energy, sustainability, transportation

The US power grid needs all of support it can get. Sad that some would stand in the way of progress.


There is no love lost between the notorious Koch brothers and the nation’s railroad industry, and the relationship is about to get a lot unlovelier. A massive new, first-of-its-kind renewable energy transmission line is taking shape in the Midwest, which will cut into the Koch family’s fossil energy business. It has a good chance of succeeding where others have stalled, because it will bury the cables under existing rights-of-way using railroad rights-of-way and avoid stirring up the kind of opposition faced by conventional above-ground lines.

The Koch brothers and their family-owned company, Koch Industries, have earned a reputation for attempting to throttle the nation’s renewable energy sector. That makes sense, considering that the diversified, multinational firm owns thousands of miles of oil, gas, and chemical pipelines criss-crossing the US (and sometimes breaking down) in addition to other major operations that depend on rail and highway infrastructure.

Artificial Photosynthesis Machine Turns Water Into Fuel

Posted by in categories: solar power, sustainability, transportation

Now, researchers are homing in on an artificial photosynthesis device that could let us do the same trick, turning sunlight and water into clean-burning hydrogen fuel for our cars, homes, and more.

Solar cells already let us convert sunlight into electricity. Artificial photosynthesis devices, however, use sunlight to turn water or carbon dioxide into liquid fuels, such as hydrogen or ethanol.

These can be stored more easily than electricity and used in different ways, allowing them to substitute for fossil fuels like oil and gas.

Tesla Model S Plaid Defeats Cars Built To Win Pikes Peak — “Nobody would expect us to be faster than that.”

Posted by in categories: sustainability, transportation

Electric motors have a lot of power and it is instant on-demand.


When Tesla unveiled its new Plaid Model S earlier this month, it took the world by storm, fueling dreams of speed, racing, and fun. In the sense of a grand finale to Tesla’s event, another event was talked about in the weeks following. That event was the annual race to the summit of Pikes Peak. Also known as “The Race to the Clouds,” the entire track winds through 156 turns over 12.42 miles as it reaches the summit of Pikes Peak.

“World’s fastest electric motorcycle” uses radical big hole technology

Posted by in categories: sustainability, transportation

There’s no motorcycle on the planet like this one. British company White Motorcycle Concepts (WMC) has put land speed record holders on notice with a 2WD, hydraulically hub-steered electric motorcycle, designed around a giant hole. The company says the WMC250EV should be capable of more than 250 mph (402 km/h) thanks to a massive 69 percent reduction in drag.

Rob White has paid his dues in the racing world, working on numerous Formula One, Le Mans Prototype, V8 supercar and World Endurance Championship race teams over the last 25-odd years. And his approach to motorcycle design is clearly influenced by the world of high-end cars.

Genetically Modified Yeast To Efficiently Make Biofuels From Discarded Plant Matter

Posted by in categories: chemistry, food, genetics, sustainability

The new system streamlines the process of fermenting plant sugar to fuel by helping yeast survive industrial toxins.

More corn is grown in the United States than any other crop, but we only use a small part of the plant for food and fuel production; once people have harvested the kernels, the inedible leaves, stalks and cobs are left over. If this plant matter, called corn stover, could be efficiently fermented into ethanol the way corn kernels are, stover could be a large-scale, renewable source of fuel.

“Stover is produced in huge amounts, on the scale of petroleum,” said Whitehead Institute Member and Massachusetts Institute of Technology (MIT) biology professor Gerald Fink. “But there are enormous technical challenges to using them cheaply to create biofuels and other important chemicals.”

Synthetic tree enhances solar steam generation for harvesting drinking water

Posted by in categories: climatology, solar power, sustainability

About 2.2 billion people globally lack reliable access to clean drinking water, according to the United Nations, and the growing impacts of climate change are likely to worsen this reality.

Solar steam generation (SSG) has emerged as a promising for water harvesting, desalination, and purification that could benefit people who need it most in remote communities, disaster-relief areas, and developing nations. In Applied Physics Letters, Virginia Tech researchers developed a synthetic tree to enhance SSG.

SSG turns into heat. Water from a storage tank continuously wicks up small, floating porous columns. Once water reaches the layer of photothermal material, it evaporates, and the steam is condensed into drinking water.

Producing methane for energy in underground repositories using solar energy

Posted by in categories: solar power, sustainability

During the winter months, renewable energy is in short supply throughout Europe. An international project is now considering an unconventional solution: Renewable hydrogen and carbon dioxide are pumped into the ground together, where naturally occurring microorganisms convert the two substances into methane, the main component of natural gas.

Underground Sun Conversion technology, patented by the Austrian energy company RAG Austria AG, offers a way to seasonally store renewable energy on a large scale and make it available all year round. In summer, this involves converting surplus renewable energy—, for instance—into hydrogen (H2). This is then stored together with (CO2) in natural underground storage facilities—for example, former natural gas deposits—at a depth of over 1000 meters.

This is where little helpers come into play: Microorganisms from , so-called archaea, convert hydrogen and CO2 into renewable methane (CH4) via their metabolism. Archaea are found all over the world, mainly in anaerobic, i.e. low-oxygen environments; they were responsible for converting biomass into natural gas millions of years ago. By feeding hydrogen and CO2 into suitable porous sandstone deposits, this process can be started all over again. The methane “produced” in the depth can then be withdrawn from the reservoirs during winter and used in a variety of ways as CO2-neutral natural gas.
