It’s Time to Take Mesh Networks Seriously (And Not Just for the Reasons You Think)

The internet is weak, yet we keep ignoring this fact. So we see the same thing over and over again, whether it’s because of natural disasters like hurricanes Sandy and Katrina, wars like Syria and Bosnia, deliberate attempts by the government to shut down the internet (most recently in Egypt and Iran), or NSA surveillance.

After Typhoon Haiyan hit the Philippines, several towns were cut off from humanitarian relief because delivering that aid depends on having a reliable communication network. In a country where over 90 percent of the population has access to mobile phones, the implementation of an emergency “mesh” network could have saved lives.

Geothermal Heat Pumps

Watch how geothermal heat pumps heat and cool buildings by concentrating the naturally existing heat contained within the earth -- a clean, reliable, and renewable source of energy.

energy.gov - June 24, 2012

Geothermal heat pumps (GHPs), sometimes referred to as GeoExchange, earth-coupled, ground-source, or water-source heat pumps, have been in use since the late 1940s. They use the constant temperature of the earth as the exchange medium instead of the outside air temperature. This allows the system to reach fairly high efficiencies (300% to 600%) on the coldest winter nights, compared to 175% to 250% for air-source heat pumps on cool days.

Ground Water Source (Open Loop) Heat Pump Systems

bge.apogee.net

An open-loop, ground-water heat pump, uses a surface or underground water source (such as a lake, river, or well) as the heat source and sink. Well water designs are the most common and seem to be the most cost effective. The well supplies both domestic water and water for the heat pump. Approximately three gallons per minute of well water are needed per ton of cooling capacity.

Ground water source open-loop heat pumps use the same concept as the ground coupled units - for example, in the Midwest the temperature of the earth near the surface and the water in it (aquifer) is typically around 55°F. Water is taken from the ground or surface water (pond, lake, etc.), circulated to the individual heat pumps and the returned to the ground via a disposal well, returned to the lake or pond, or where permitted discharged into a stream or river.

When more units are heating than cooling the circulating water temperature drops prior to disposal. Conversely, when more units are cooling than heating, the circulating water is warmed prior to disposal.

How My Mobile Devices are Ready for the Next Storm: Fenix ReadySet

      

gigaom.com - by Kevin C. Tofel - November 7, 2012

After 4 days without power thanks to Hurricane Sandy, something arrived today that will help keep my mobile devices fully charged and connected to the web. I backed a Fenix ReadySet on Kickstarter, which is a large battery that charges with an included solar panel.

Fed Flood Maps Left NY Unprepared for Sandy — and FEMA Knew It

Flooding in Red Hook, Brooklyn after Sandy (Flickr/gunnicool)

The agency ignored state and city officials' appeals to update the maps with better data until it was too late.

wnyc.org - December 6, 2013

When Patrice and Philip Morgan bought a house near the ocean in Brooklyn, they were not particularly worried about the threat of flooding.

Federal maps showed their home was outside the area at a high risk of flood damage. . .

. . . But the maps drawn up by the Federal Emergency Management Agency were wrong. And government officials knew it.

Army Corps Restores Marsh Islands in Jamaica Bay N.Y. Posted 9/13/2012

By Vince Elias
New York District Public Affairs

It is estimated that approximately 1,400 acres of tidal salt marsh have been lost from the marsh islands in Jamaica Bay, New York since 1924, with the system wide rate of loss rapidly increasing in recent years. From 1994 and 1999, an estimated 220 acres of salt marsh were lost at a rate of 47 acres per year.

With the Manhattan skyline less than 10 miles to the north, the eight by four mile marsh islands complex is an integral part of the Bay, which has been targeted for restoration by the U.S. Army Corps of Engineers, National Park Service (Gateway), New York State Department of Environmental Conservation, New York City Department of Environmental Protection, The Port Authority of New York and New Jersey, the National Resources Conservation Service and the New York/New Jersey Harbor Estuary Program.

To quell further erosion of the islands, and adding to an already impressive list of habitat restoration projects in the Bay, the Army Corps commenced the placement of sand from the Harbor Deepening Project’s Ambrose Channel contract in August 2012 to restore Black Wall and Rulers Bar marsh islands.

Health officials announce public exposures to new measles case

Health officials announce public exposures to new measles case

 

Tuesday, November 26, 2013

Local public health officials have confirmed a measles infection in an infant who was in several locations in King County during the contagious period. The infant is a King County resident who was too young to be vaccinated and likely exposed to the measles while overseas.

What to do if you were in location of potential measles exposure

Most people in our area have immunity to the measles through vaccination, so the risk to the general public is low. However, all people who were in the following locations around the same time as the individual with measles should:

Biggert-Waters Flood Insurance Reform Act of 2012 (BW-12)

http://www.fema.gov/flood-insurance-reform-act-2012

 

Flood Insurance Reform Act of 2012

 

In July 2012, the U.S. Congress passed the Biggert-Waters Flood Insurance Reform Act of 2012 (BW-12) which calls on the Federal Emergency Management Agency (FEMA), and other agencies, to make a number of changes to the way the National Flood Insurance Program (NFIP) is run. Some of these changes already have occurred, and others will be implemented in the coming months. Key provisions of the legislation will require the NFIP to raise rates to reflect true flood risk, make the program more financially stable, and change how Flood Insurance Rate Map (FIRM) updates impact policyholders. The changes will mean premium rate increases for some—but not all—policyholders over time. Homeowners and business owners are encouraged to learn their flood risk and talk to their insurance agent to determine if their policy will be affected by BW-12.

How Local Governments Hinder Our Response to Natural Disasters

theatlanticcities.com - October 28th, 2013 - David Wachsmuth

The northeast Atlantic seaboard is the most densely urbanized area of the United States. And over generations, a bewildering patchwork of governance has evolved, with thousands of municipalities, hundreds of special-purpose agencies, dozens of cross-state partnerships, and a handful of states all sharing—and fighting over—governmental responsibilities.

The state of New Jersey alone has 565 municipalities representing a population only slightly larger than the single municipality of New York City.
