Chinese Farmers Paid to Convert Livestock Wastes to Fuel and Fertilizer

Janina Lazo-Cruz — Fri, 01 Sep 2017 19:11:15 +0000

China encourages its farmers to develop animal waste processing facilities, which allow conversion of wastes to fertilizer and fuel, by giving them incentives. This is to address the country’s problem on increasing animal waste due to the rapid growth of poultry and hog farming. The objective is to avoid both the release of hazardous pollution […]

Big Oil and Gas Companies Will be Struggling in Years to Come

Annika Tostengard — Tue, 20 Oct 2015 05:38:10 +0000

As oil prices drop, the biggest oil and gas companies may be the ones that suffer the most. While smaller companies may find it easier to start and stop work as the market fluctuates, the largest companies will likely have a difficulty adjusting. In addition, companies are also cutting their exploration budgets, which will significantly […]

UIC Team Finds More Efficient Way to Convert Carbon Dioxide into Fuel

Danny Harper — Sat, 07 Dec 2013 07:15:40 +0000

The ease at which we can burn hydrocarbons to produce energy has led to huge gains in productivity and quality of life for millions, but it also coincides directly with the extreme rise in carbon dioxide emissions that we have been observing since the industrial revolution. This has led many in the scientific community to […]

Audi’s Synthetic Fuel Produced With Solar and Wind Power

Benji Jerew — Fri, 25 Jan 2013 20:27:35 +0000

Audi is set to release a number of natural-gas [NG] powered vehicles this year, such as the Audi A3 Sportback TCNG. It can run on petroleum-sourced NG, which is abundant, but is also a carbon-positive fuel. In order to make these vehicles greener, a carbon-neutral fuel would be even better. To that end, Audi is […]

New Nanofibers Making Sulfur-Free Fuels

Leigh Hutchens — Wed, 19 Dec 2012 07:23:44 +0000

Sulfur compounds in fuels can cause problems. Big problems. To combat this issue, researchers at the University of Illinois have developed mats of metal oxide nanofibers that scrub sulfur from petroleum-based fuels in a much more effective way than traditional materials and methods. Employing this technique would improve performance for fuel-based catalysis, facilitate toxic gas […]

Osaka Student Team Creates Hydrogen-Powered Car From Scratch

Ovidiu Sandru — Mon, 16 Jan 2012 14:51:21 +0000

Everyone started building battery-powered electric vehicles lately, but few are those who built cars whose power comes from hydrogen fuel cells. Such an example comes from a team of students at Osaka Sangyo University, who built a fuel cell-powered car from scratch, creating Japan’s first non-industrial team to ever accomplish this. Actually, they haven’t been […]

What Is The Biodiesel?

Ovidiu Sandru — Wed, 06 Feb 2008 14:20:18 +0000

What is biodiesel? Biodiesel is a fuel derived from vegetable oil or animal fats that can be an additive to or entirely replace conventional petroleum diesel fuel. In the United States, the majority of biodiesel is made from soybean or canola oils, but is also made from waste stream sources such as used cooking oils […]

New Technologies for Hybrid Cars

Ovidiu Sandru — Wed, 06 Feb 2008 07:47:55 +0000

Considering the constant threat of global warming, hybrid vehicles are here to stay, but their success isn’t yet a noticeable one. U.S. consumers are expected to purchase approximately 350,000 Hybrid vehicles annually by the year 2008. Ultimately the choice is in your hand. Buying a normal car would mean another threat for the environment for […]

Biogas Production Principle

Ovidiu Sandru — Wed, 06 Feb 2008 07:31:48 +0000

Biogas is generated when bacteria degrade biological material in the absence of oxygen, in a process known as anaerobic digestion. Since biogas is a mixture of methane (also known as marsh gas or natural gas, CH4) and carbon dioxide it is a renewable fuel produced from waste treatment.

Diesel or Hydrogen?

Ovidiu Sandru — Tue, 29 Jan 2008 21:31:14 +0000

by Jack Peckham San Diego-Futurists talk dreamily of a “hydrogen future” where the internal combustion engine and fossil fuels are replaced by “clean” hydrogen and fuel cells. But practical reality tells a far different story today: Diesel/ distillate fuels (including jet fuel) do all the heavy lifting on this planet-for good reason. That’s because distillates […]

How To Boost Your Car’s MPG With Water

Ovidiu Sandru — Tue, 29 Jan 2008 21:02:35 +0000

You can always boost your car’s performance by adding a so-called “cell” to your car’s air input. This cell produces hydrogen through electrolysis of water impurified with baking soda, for example, or another electrolyte. The plans are easy to build at home during your weekend, and to test them on your carburretor or fuel-injection engine. […]
