5 phase SRM motors

DIY Electric Car

I don't think the ambient temperature matters much, because all modern EV motors run high enough power density that they need active (normally liquid, often oil) cooling; their internal operating temperature can get pretty high, even in a temperate climate. Both rotor designs experience heating.

Global Ice Age Climate Patterns Influenced by Bering Strait

Green Car Congress

In a vivid example of how a small geographic feature may have far-reaching impacts on climate, new research shows that water levels in the Bering Strait—which separates the US and Russia by only 90 kilometers (56 miles)—helped drive global climate patterns during ice age episodes dating back more than 100,000 years.

US and Japan successfully complete Arctic field trial of gas hydrate production technology using CO2-methane exchange within structure

Green Car Congress

US Energy Secretary Steven Chu announced the completion of a successful test of technology in the North Slope of Alaska that was able to safely extract a steady flow of natural gas from methane hydrates. Such an effort would again require engaging private sector and international partners. Source: NETL. Click to enlarge.

Study Finds East Siberian Arctic Shelf Showing Instability and Widespread Venting of the GHG Methane; Releases May Be Much Larger and Faster Than Anticipated

Green Car Congress

A section of the East Siberian Arctic Shelf (ESAS) seafloor that holds vast stores of frozen methane (CH 4 ) is showing signs of instability and widespread venting of the gas, according to the findings of an international research team led by University of Alaska Fairbanks scientists Natalia Shakhova and Igor Semiletov. Shakhova et al.

ICCT finds growth in shipping in Arctic could increase pollutant emissions 150-600% by 2025 with current fuels

Green Car Congress

While that report projected vessel activity, it did not explore the environmental impacts of increased shipping in terms of air emissions or the potential climate impacts from increases in short-lived climate pollutants such as black carbon. The emissions report focuses on the low- and mid-range diversion scenarios—i.e.,

He said that the Administration has already approved 39 new shallow water permits, and an additional 7 deepwater permits in recently weeks. We’re also exploring and assessing new frontiers for oil and gas development from Alaska to the Mid- and South Atlantic. America holds only about two percent of the world’s proven oil reserves.

NRC report projects sea level off most of California will rise at slightly higher rate than global average; lower rate for Oregon, Washington, NorCal; variety of factors affect outcome

Green Car Congress

As Earth warms, sea levels are rising mainly because: (1) ocean water expands as it warms; and (2) water from melting glaciers and ice sheets is flowing into the ocean. fingerprints) of melting of ice from Alaska, Greenland, and Antarctica; and vertical land motions along the coast.
