| It’s Massive Yet Tiny | Len Calderone for | AltEnergyMag | Dec 2012 |
A 14 x 14” MYT engine has 850 cubic inches of displacement and weighs 150 pounds, compared to a conventional engine, which would weigh 3,000 pounds to produce the same power. The engine needs no oil, as the biofuel is the lubricant due to the high lubricity of biofuel. With every tank of fuel, the engine is circulated with more than 20 gallons of fresh engine oil compared to 5 quarts of engine oil circulating over 3,000 miles in conventional engines. You can now skip changing oil forever and have an engine with longer life. |
| Bankable Data and Interoperability Standards | Sonia Turanski | RainWise Inc | Oct 2012 |
Data quality derives from the combination of accurate instruments plus Data Encoding Standards: one can take highly accurate data samples but if there is no agreement as to what the data means, the data could be considered to be of low quality because of its inability to improve the decision making process. |
| Nuclear Fusion | Florian Ion Petrescu | Bucharest Polytechnic University | Aug 2012 |
Research into controlled fusion, with the aim of producing fusion power for the production of electricity, has been conducted for over 60 years. It has been accompanied by extreme scientific and technological difficulties, but has resulted in progress. At present, controlled fusion reactions have been unable to produce break-even (self-sustaining) controlled fusion reactions. Workable designs for a reactor that theoretically will deliver ten times more fusion energy than the amount needed to heat up plasma to required temperatures (see ITER) were originally scheduled to be operational in 2018, however this has been delayed and a new date has not been stated. |
| Battery Performance of Microfiber/Nanofiber Lithium Ion Battery Separators | Brian Morin, PhD | Dreamweaver International | Aug 2012 |
Current stretched porous film battery separators for lithium ion batteries are thin, strong, and provide a good barrier between electrodes, at the cost of having very high internal resistance and low ionic flow due to low porosity and high “dead space” that come from starting with a solid material and trying to impart porosity. This work uses an alternative approach, where linear nanofibers and microfibers are combined in wet laid nonwoven processes to give separators that are strong and thin, but have higher porosity (60-70%) and so have much higher ionic flow. |
| Momentum / Inertial Energy | Gare Henderson | Gravitational Systems Engineering, Inc. | Jun 2012 |
Where M/I shines is in the delivery of vast amounts of energy with no fuel cost. When compared to other non-fuel sources, [solar, wind and hydro-electric] a dense 1 mile M/I installation will generate, during rush hour, as much energy as a 3 square mile photovoltaic installation on a very sunny day. |

| The Solar Power Paradox: Alternative Energy Can’t Run on Oil | Stan Levy And David Lee | BioSolar | Oct 2009 |
As the PV business continues to grow, new backsheet constructions are continually being introduced. But the products we use in our efforts to be more sustainable have a bigger footprint than we think. Currently, there are at least ten commercial manufacturers of traditional PV backsheets, with traditional products in the development stage. Traditional backsheets, the protective covering on solar cells, are produced mainly from polyester and Tedlar films. Polyester is made from petroleum and Tedlar is solvent-cast using DMAC, a highly toxic industrial solvent. Both of these products defeat the purpose of clean, green energy, and as the demand for solar energy increases, so does this issue. |
| Solar Cities Proposition | Paul Lyons | Oct 2009 |
"Buildings like trees, cities like forests." When Michael McDonough, author and sustainability architect, suggested this be the new paradigm for the future, he was referring to the creation of buildings and communities that are self-sufficient. He also reminds us that "waste is a human phenomenon", so the concept of recycling and efficiency is central to the attainment of environmental stewardship. Through integration, energy management, efficiency techniques and technologies it is now possible to create buildings that are 'greener' and more ecologically synergistic than ever before. | |
