And Again...

Again and again...

In May of this year more than 150,000 customers across Ontario left without power three days after a powerful storm tore through the province, knocking down power lines and trees, forcing several schools to close and leaving behind significant damage.

Hydro One said the damage from the storm included more than 1,400 broken poles, 300 broken crossarms and nearly 200 damaged transformers as well as "countless trees."

In Ottawa, Mayor Jim Watson said "most" customers still without power should have service restored within the next two to three days. But he warned it will be several weeks before the storm damage is fully cleaned up.

Joanna Eyquem, managing director of climate-resilient infrastructure for the Intact Centre on Climate Adaptation at the University of Waterloo, said efforts to slow climate change mean we are becoming more reliant on electricity and it is more important than ever to safeguard the power grid against major breakdowns.

"We can't have everything kind of falling apart because we have power outages as well because it just makes us less resilient," she said.

 A 2019 climate vulnerability study done for Hydro Ottawa warned that storms with winds above 120 kilometres an hour posed an extremely high risk for the city's power grid.

 

And now.

Powerful storm Fiona made landfall in eastern Canada's Nova Scotia early on Saturday, the U.S. National Hurricane Center (NHC) said, with maximum winds of 90 miles (144 kilometers) per hour.

"Fiona is expected to affect portions of Atlantic Canada as a powerful hurricane-force cyclone today, and significant impacts from high winds, storm surge, and heavy rainfall are expected," the NHC said.

Although a gradual weakening was forecast during the next couple of days, Fiona was expected to maintain hurricane-force winds until Saturday afternoon, the NHC said.

The storm has blown over trees and powerlines and leaving hundreds of thousands of homes and businesses without electricity, according to Reuters on Saturday.

Some 79 percent of customers, or 414,000, were without power in Nova Scotia, and 95 percent, or 82,000, had lost power on Prince Edward Island, utility companies said. The region was also experiencing spotty mobile phone service. Police across the region reported multiple road closures, Reuters said.

Formerly designated a hurricane, the storm battered Caribbean islands earlier in the week, killing at least eight people and knocking out power for virtually all of Puerto Rico's 3.3 million people during a sweltering heat wave. Nearly a million people remained without power five days later.

Canadian Prime Minister Justin Trudeau delayed Saturday's departure for Japan, where he was to attend the funeral of former Prime Minister Shinzo Abe, to receive briefings and support the government's emergency response, Press Secretary Cecely Roy said on Twitter.

A hurricane warning was in effect for much of central Nova Scotia and Prince Edward Island, home to more than 150,000 people, and parts of Newfoundland, the Miami-based NHC said.

Canadian Hurricane Center meteorologist Ian Hubbard said on Friday the effects of Fiona would be felt over a wide area.

"The center of it is one thing, but the weather that's associated with it in terms of the rain and where all the strong winds are, it's going to be over a much larger area," he said.

"Many, many places away from the center of the storm are still going to be seriously impacted from this," said Hubbard.

Canadian authorities sent emergency alerts in Nova Scotia and Prince Edward Island, warning of severe flooding along shorelines and extremely dangerous waves. People in coastal areas were advised to evacuate.

The storm could prove more ferocious than the benchmarks of Hurricane Juan in 2003 and Hurricane Dorian in 2019, Canadian Hurricane Center meteorologist Bob Robichaud told a briefing.

The country's two largest carriers, Air Canada and WestJet Airlines, suspended regional service starting Friday evening.

There is a solution: Autonomous Mobile Energy System (AMES). An array of the AMES modules would be located in areas prone to energy disruptions and wait in a "sleeping" mode. Then, when the moment comes, they are activated and deployed automatically, providing much needed energy for rescue and relief workers, residents and businesses. The AMES, developed by Ascent Systems Technologies, is currently in the final round of the Canadian Department of National Defence (DND) contest developing a prototype for the Canadian Armed Forces (CAF) relocatable temporary camps. Most recently Ascent was awarded a contract to develop a prototype of the autonomous environment monitoring and security system for the DND assets in the Arctic.

Tornadoes Leave Trail of Devastation Across Six States

 

 

On December 11, 2021 Kentucky, Illinois, Tennessee, Arkansas, Missouri and Missisippi were hit by a serious of tornadoes. More than a hundred people were killed, thousands of homes destroyed, roads got blocked by debris, power and water services lost. While this kind of events was the most serious in more than 40 years, there are reasons to believe that they and other weather-related disasters will be becoming more frequent and likely more severe in the near future due to continuing and increasing effect of global warming. At least part of the blame must be put on greenhouse gas (GHG) emissions released by human activities. Regardless, we need to be better prepared for these and other natural as well as technological disasters. Nothing in our modern world can function without energy. Our reliance on large centralized energy infrastructure leads to the domino effect of a multiple failures affecting large areas and many people. That could be avoided by transitioning to decentralized energy infrastructure and to autonomous systems.  

    

The Autonomous Mobile Energy System (AMES) module is a technology at the intersection of clean energy, space-grade robotics and AI / machine learning. It can provide heating and electricity without the need for fuel supply or connection to the power grid, using its tiered solar collectors and internal energy storage. Moreover, its embedded sensors warn the system when conditions become dangerous for normal operation. The computer commands the system to retract into the safe "turtle" mode until such time when the conditions become favorable again. Once it decides it is safe, the AMES module deploys again into operational mode automatically. Because each module operates individually, no one which becomes inoperable for whatever reason, affects another, thus avoiding a domino effect. The array of the AMES modules will provide heating and electricity for essential needs while rescue and recovery operations are under way.
