4/30/12 Storm Shelter Surge

More and more families are staring to take matters into their own hands against dangerous storms by building their own storm shelters. Some people are hiring companies to do it for them, others are building them with their own bare hands.

Companies like Twister Safe, Storm Defend, Survive-A-Storm, and National Storm Shelters all have products that can be placed either in/under your garage, in a closet, or buried on their own plot of land. While sizes vary to the specific brand, most can fit up to 4 people. Before the Joplin, Missouri tornado of last year, one of those companies, Twister Safe, only had four employees. They now employ 20, and the company is still growing.

"Business has probably quadrupled, at least," owner Enos Davis said. "We're selling 400 to 500 a year now, compared to maybe 100 before."  Below is a picture of one of the newly-built shelters in Joplin, Missouri.

Many of these safe rooms feature thick steel or concrete walls and doors that can withstand winds up to 250 mph. Most of them have no windows, no light fixtures, and no electricity (many keep flashlights or battery operated lanterns inside). They are simply meant to be a small, reinforced place to ride out the storm. Depending on the company, and your geographic location, these shelters generally cost anywhere from $3,000 to $6,000.

FEMA has given funds to states like Alabama, Missouri, and Mississippi, just to name a few, to have community storm shelters built for people to go when storms are on the way.

Others have opted to build their own shelters, like Freddie Wooten of Henegar, Alabama (pictured below with his shelter). He decided to build his own after his community was hit by an EF5 tornado last April. He gathered the supplies and everything necessary to build it at his own cost.

4/22/12 Earth Day Green Inventions

Earth Day is always a day to remind us to be green. People all over the world try to conserve energy use, clean up their communities, plant new trees and flowers, among many other things. Every year "being green" seems to become cooler and trendier. However, it isn't always the cheapest trend. Thanks to a few new products though, that is expected to change.

First we will start will efficient light-bulbs. Trading out your incandescent bulbs for compact fluorescent (CFL) ones will save you money on your electric bills, but some people aren't convinced. Many of the complaints about using CFL bulbs revolve around what to do if the bulb breaks, since the clean-up process is not only lengthy and tedious, but also dangerous since there is a large amount of mercury in CFL's. The more common complaint is that they cost more initially, and takes a while to see a return on your investment. However, there is a new super-duper energy-efficient LED light bulb that just came on the market that hopes to curb those last 2 complaints.

This is the new Philips award winning LED energy efficient light bulb. This new bulb can reportedly last up to 10 years or more, which will ultimately save consumers money, because they won’t have to replace these bulbs nearly as often as others. The big hold-back...the price. The sticker price for this bulb is $60, however, thanks to online deals, rebates and subsidies, the price that consumers will pay will likely only be around $40-50. So how does a homeowner justify spending that much on a light-bulb? The company says that the bulb will save plenty of energy also, since it consumes less than 10 watts while producing light equivalent to a 60-watt incandescent bulb (an 83% energy savings).


Another idea is solar panels. Well, the panels themselves aren't a new idea, but using them on windows to generate electricity with a nearly transparent plastic film that can be sprayed on or rolled on with an adhesive, that is new. The solar energy industry is trying to come up with new ways to incorporate solar energy in people's homes, without having to place bulky panels on the roof. New Energy Technologies has developed new plastic polymers that can be sprayed right onto your windows to create a film which will then produce electricity. The product is called SolarWindow, and the process generates electricity using natural or artificial light, such as fluorescent lighting, even on homes that do not face south.

“It will generate electricity even in low light conditions, so you can coat windows that are facing east or west,” says , says John Conklin, chief executive officer of New Energy Technologies. The hope is while this new product won't be able to produce the same amount of solar energy that rooftop panels do, they will cost much less, making them a more affordable option for many people.

4/17/12 Weekend Tornado Recap

Over the weekend many dozens of tornadoes were reported in several states. There were a total of 110 tornado reports for Saturday, but there were likely only 75 that actually made it to the ground. A total of 6 people dies, all of which were in the state of Oklahoma. There were also around 50 injuries from tornadoes in other states. Below is a map of the tornado warnings and actual corresponding reports of tornadoes that touched down on Saturday.

Nebraska- The big story here was the baseball size hail, and a lot of it. There were 7 tornadoes in the state, but most of them hit farmland and rural areas, so there were no injuries or fatalities, and just some minor structural damage to some barns, outbuildings, and some trees down.

Kansas- Multiple tornadoes hit here including two EF3's in western part of the state. Sedgwick county, where Wichita is located, has preliminary damage estimates as high as $283 million. There was also an EF4, the highest rated tornado from Saturday's storms, near the town of Salina.

 

Oklahoma - Oklahoma governor declared a state of emergency for 12 counties. The town of Woodward, which is about 140 miles NW of Oklahoma City, was the hardest hit. This is where all of the tornado fatalities came from. Thousands remained without power well into Sunday.

Iowa-This state in particular had a large part of the town of Thurman, which is in the western part of the state, destroyed by an EF2 tornado. Thankfully there were no injuries or fatalities in that area. The state as a whole received four tornadoes, two of them were EF2, one EF0, and one EF1.

In total there were seven EF0 tornadoes, five EF1 tornadoes, three EF2 tornadoes, four EF3 tornadoes, and one EF4 tornado across four states in the Great Plains. Below is a breakdown of the confirmed rated tornadoes in each state:

EF4- Salina, KS
EF3- Wichita, KS
EF3- Woodward, OK
EF3- Greensburg, KS
EF3- Macksville, KS
EF2- Cook, NE
EF2- Thurman, IA
EF2- Creston, IA
EF1- Nebraska City, NE
EF1- McClelland, IA
EF1- Manchester, KS

New Tornado Warning Wording

UNSURVIVABLE, CATASTROPHIC, COMPLETE DEVASTATION. These are just some of the new words that will be added to future Tornado Warnings to add emphasis to the possible dangers. At the beginning of the month five weather service offices located in Kansas and Missouri will use a new kind of warning wording that's based on the severity of a storm's expected impact. They claim that the goal is to be able to more effectively communicate the risks people about to face with an impending storm in their area.

"We'd like to think that as soon as we say there is a tornado warning, everyone would run to the basement," said Ken Harding, a weather service official in Kansas City. "That's not how it is. They will channel flip, look out the window or call neighbors. A lot of times people don't react until they see it."

The new wording will be tested using two tiers of warnings for thunderstorms and three tiers for tornadoes, each based on severity. After the testing period is over, a research team in North Carolina will analyze the results, and help the weather service decide whether to expand the new warnings to other parts of the country.

"We have found in Mississippi and Alabama and various other Southern states that people feel they would constantly be going to a shelter if they heeded every tornado warning," Laura Myer, a social science research professor at Mississippi State University, explains. "For people in mobile homes, that's the craziest thing. To get to a shelter, they have to leave home. They feel like if they left during every watch or warning, they would be on the road all the time."

Andy Bailey, a meteorologist with the NWS office in Missouri, said it might look something like this: "THIS IS AN EXTREMELY DANGEROUS TORNADO WITH COMPLETE DEVASTATION LIKELY. ... SEEK SHELTER NOW! ... MOBILE HOMES AND OUTBUILDINGS WILL OFFER NO SHELTER FROM THIS TORNADO — ABANDON THEM IMMEDIATELY."

The reason for the weather service's written bulletins is to target the primary audience-broadcasters who issue warnings on the air along with emergency managers that activate weather sirens. They are hoping that the new wording would give folks who would be in a tornado event like Joplin, Missouri, an urgency that's hard to ignore.

"After hundreds of times of similar thunderstorms approaching Joplin, many of those with tornado warnings attached, and you see them pass ... after all those storms, you kind of get jaundiced about the warnings and tend not to give them the weight you probably should give them," said Jeff Lehr, a reporter at The Joplin Globe, and long-time Joplin resident.

4/1/12 Big Blue Planet: 50 Years of Photos

Earth has been photographed by NASA for the last 50 years, although the images have certainly changed over time. The first from April 1960, was a grainy black-and-white image taken by the Television InfraRed Observation Satellite, or TIROS-1, which carried with it two small cameras, one for capturing wide views of the Earth as a whole, and the other for more detailed views. In its first three months alone the satellite took 23,000 images, which were used mainly for weather forecasting.

In 2005, NASA created the "Blue Marble: Next Generation" series, which was a year's worth of observations taken by various satellites. The series was named after a famous photo of the Earth taken by the Apollo 17 crew in 1972. Recently, NASA has gone a few steps further by taking new pictures from the perspective of 7,918 miles from Earth. Images were taken during six orbits of the Earth and stitched together to create a single composite image. Earlier this year NASA released two such images of the Earth, one of the Western Hemisphere (below) in January. Then a few weeks later, they released an image of the the Eastern Hemisphere (above).

Another famous picture from space is that of Earth at night. These images were originally created by the Defense Meteorological Satellite Program (DMSP) and the Operational Linescan System (OLS) to view clouds by moonlight. Since most cities tend to be along coastlines, even without the underlying map, the outlines of many continents would still be visible due to this. Interestingly, the U.S. interstate highway system appears as a lattice connecting the brighter dots of city centers when you zoom in.
