In a paper being presented at WCX SAE World Congress Experience in Detroit this week, a team from MIT is proposing the use of a flex-fuel gasoline-alcohol engine approach for a series-hybrid powertrain for long-haul Class 8 trucks. Ethanol or methanol would be employed to increase knock resistance. —Daniel Cohn.

Deep-sea-mining schemes propose sending down tractor-sized vehicles to vacuum up these nodules and send them to the surface, where a ship would clean them and discharge any unwanted sediment back into the ocean (e.g, —Thomas Peacock, professor of mechanical engineering at MIT and co-corresponding author. earlier post ).

Now, MIT engineers are proposing using an ammonia-based selective catalytic reduction (SCR) system that could result in an approximately 95% reduction in NO x emissions in exchange for a ~0.5% The trend towards smaller engine cores with smaller mass flow rates in the core stream, presents new opportunities for emissions control.

John Hansman , an aeronautics and astronautics professor at MIT and director of the university’s International Center for Air Transportation. And the hydrogen would have to either be produced through clean or nuclear energy to provide real climate benefits, the paper noted. asks Professor R. The first challenge is hydrogen production.

Aviation’s huge carbon footprint could shrink significantly with electrification. To date, however, only small all-electric planes have gotten off the ground. Their electric motors generate hundreds of kilowatts of power. To electrify larger, heavier jets, such as commercial airliners, megawatt-scale motors are required.

Now, researchers at MIT have found a way to streamline the discovery process using a machine learning system. MIT professor of chemical engineering Heather Kulik says they “are really fascinating, functional materials that are unlike a lot of other material phases. These can exist in a vast number of different forms.

MIT researchers have discovered a way to increase the efficiency of thermoelectric materials threefold by using “topological” materials, which have unique electronic properties. In the end, this could be a clean-energy way to help us use a heat source to generate electricity, which will lessen our release of carbon dioxide.
