Eraole is a unique machine in a sea of unique craft.  Powered by a combination of sunlight, Total biofuel, and hydrogen, Raphael Dinelli’s tandem-winged biplane has been under development for many years.  With it, Raphael hopes to cross the Atlantic in 2019, Duplicating Charles Lindbergh’s 1927 flight at about half the Spirit of the Spirit of St. Louis’s speed. Eraole’s first flight took place in 2016.  The video will allow you to compare its look then with its changed appearance today. Changes of Plane, Changes of Plans Dinelli’s original plan for the flight included the use of an algae-derived fuel to run Eraole’s engine/generator.  As reported by La Tribune, though, “For four years, the Ocean Vital Foundation conducted research with …

Ammonia + Light = Hydrogen

Hydrogen continues on its course of always being five to ten years away as a cheap, viable storage mechanism for energy.  The ideal of driving a car that emits only water vapor (or flying an airplane that zooms about on a few pounds of H2) seems like an ever-distant dream. Tina Casey, writing for Gas2.com reports on Rice University solution using stinky ammonia that might clear the air for hydrogen, though.  She explains that the October 8th celebration of the fourth annual Hydrogen and Fuel Cell Day was great for natural gas stakeholders, since the gas is the primary source today for hydrogen.  Her headline indicates this could become a leading way to store and extract H2: “Forget the Hydrogen …

Biofuels from Many Sources

We’ve looked at an array of different biofuel sources ranging from used cooking oil and algae to farm and municipal waste.  This is essential as the percentage of airline emissions becomes a bigger part of our overall greenhouse gas situation.   The Guardian reports, “A 2017 estimate said air travel accounted for 2.5% of all carbon dioxide emissions, with the total emissions expected to quadruple by 2050.”We’ll look here at how some of the early efforts have panned out and examine a late-breaking surprise or two. Mustard Seeds? According to the Guardian, “A Qantas plane powered partly by mustard seeds has become the world’s first biofuel flight between Australia and the United States, after landing in Melbourne on [January 30, 2018].” …

Lithium-Oxygen Battery Breakthrough

The University of Waterloo (Ontario, Canada – not far from Niagara Falls) News, reported, “Chemists make breakthrough on the road to creating a rechargeable lithium-oxygen battery.”  Dr. Linda Nazar, Canada Research Chair in Solid State Energy Materials, led a team that “Resolved two of the most challenging issues surrounding lithium-oxygen batteries, and in the process created a working battery with near 100 per cent coulombic efficiency.” The new work, which appears this week in the journal Science, Proves that four-electron conversion for lithium-oxygen electrochemistry is highly reversible.”  Waterloo is the first to achieve this, doubling electron storage in lithium-oxygen (Li-O2 – also known as lithium-air) batteries.  The video below touches on this and a great many other chemistries. Dr. Nazar …

BioLEC – First There was Light, Then There Was Energy

Trees Have Been Doing it For Years It’s a bit odd to think of trees and quantum physics in the same sentence.  Your editor used to think of sunlight striking leaves …

Lange Research Shows Six-Motor, Fuel-Cell Driven E2 at Aero Expo

Lange Aviation explained the large glider-like machine on display at the 2018 Aero Expo this way: “During this year’s AERO in Friedrichshafen, a mock-up of the Antares E2 was displayed publicly for the first time by our sister company, Lange Research Aircraft GmbH. The Antares E2 is an aircraft with an extreme endurance and very high reliability, which has been designed primarily to address maritime monitoring tasks such as fishery control. In order to fulfill the design goals, a novel propulsive system using six fuel-cell systems and six over-wing propulsors has been developed.  A Large, Heavy Machine Beyond Glider Status Weighing in at a hefty 1,650 kilograms (3,630 pounds), the Lange E2 carries that weight on a 23 meter (75.45 …

A U. S. Debut in Chicago Mary Grady, writing in AVweb, reports that “Siemens brought its prototype electric aircraft to the U.S. this week for the first time, showcasing the airplane at the company’s Innovation Day in Chicago. ‘Electric propulsion is one of the transformative technologies that will help the industry meet the goals of reduced fuel, emissions and noise,’ said Teri Hamlin, vice president of electric propulsion for Siemens. ‘By accomplishing testing on our systems on select flying testbeds in the lower power classes, we are gaining valuable experience and knowledge that accelerates and validates our other developments in hybrid-electric propulsion systems in the high power classes.’“ Testing in Waco Further testing of the technology will take place in …

Earth, Air, Water and Jet Fire

“I have always loved the desert. One sits down on a desert sand dune, sees nothing, hears nothing. Yet through the silence something throbs, and gleams.” Antoine de Saint-Exupéry, The Little Prince The SOLAR-JET project (Solar chemical reactor demonstration and Optimization for Long-term Availability of Renewable JET fuel. or SOLAR-JET) pulls carbon dioxide from the air, mixes it with water and exposes the mix to 1,500 degree (Centigrade) concentrated solar energy and makes a synthetic natural gas, with oxygen as the only exhaust.  Attempting to produce a useable fuel from CO2 has been an obsession for many over several decades.  Attempts to capture and store CO2 are expensive and usually only hide the carbon, ostensibly for eternity. SOLAR-JET explains its objectives …

Toyota, BMW Fahrting Around with Clean Energy

Dean Sigler Biofuels, Electric Powerplants, Fuel Cells, Hydrogen Fuel, Solar Power, Sustainable Aviation 0 Comments

Fahrt is German for drive, to clear things up immediately.  Both Toyota and BMW are experimenting with the cruder form of the word, though, to bring about greener, cleaner driving.  Both have bio-energy plans that use animal and even human waste to generate methane – a greenhouse gas that when burnt, combats air pollution.  Variations on the theme may someday power our aircraft. Harold Bate and a Little Prehistory This is not a new idea.  Harold Bate, a Devonshire farmer, became a counter-culture hero in the 1970s by powering his Hillman Minx sedan with manure.  Like all visionaries, Harold was a bit ahead of his time, but became well known and envied when the Arab oil embargo of that decade …

Faradair BEHA, an Electric Triplane for the Future

Triplanes were popular in World War One because they allowed great maneuverability for dog-fighting, a supreme survival necessity.  Their success in designs by Fokker and Sopwith, among others, gave them a certain panache.  Now, a Bristol, England-based company hopes to revive the triplane as a commuter aircraft ready to fly from regional airports. Faradair®, named after English physicist Michael Faraday*, hopes to craft an airplane that will allow flight from smaller regional airports and compete with even well-established rail service.  Their craft, BEHA – Bio-Electric Hybrid Aircraft, will fly six to eight lucky passengers on a quiet inter-city ride powered by a 300-horsepower internal combustion engine and two electric motors in a parallel-hybrid arrangement. Neil Cloughley, Managing Director and Founder …
