Concrete Steel Bollard-Preventing Smash and Grab Thefts

Solution for StLouis Smash and Grab Thefts-Repost

The Recent Smash and Grab Thefts rampant in the StLouis Region has prompted me to offer a Vehicle Barrier to Secure any Local StLouis store front from costly damage and the insurance claims that come from Smash and Grab Thefts.

Protective Bollards come in many shapes and sizes.  The drawing below is an Low Cost Alternative to the Protective Barriers seen around Banks, Security Offices and other buildings that house valuable assets.

As in all the projects I’m called to work on I go above and beyond the normal scope and choose to add additional protection by setting the Protective Ballard a Minimum depth of 36 Inches into the walkway.

Eliminating Solar Panel Fires from Wire Faults

WHAT COULD HAVE STOPPED THE SOLAR PANEL FIRE ON THEWEBSTER GROOVES SCHOOL IN STLOUIS MO?

(previously published on Sister Site: http:stlouisrenewableenergy.blogspot.com)

 Solar Panels that utilize the M215 MicroInverters made by Enphase Energy could have stopped the Solar Panel fire before the fire started.

I realize that is a rather boastful statement made by someone who promotes, sells, and installs Solar PV systems for the StLouis Region and chooses to utilizeGreen Building in all their Construction Activities.

But the Great Minds behind [The Next Generation of Microinverter] the Enphase M215 MicroInverters that provide 96% CEC efficiencyequals more energy production also built the M215 MicroInverter with a GFI [Ground Fault Detection Interrupt] shut off.  Similar toGFI Electrical Outlets pictured in the photo below.

GFI-Ground Fault Interrupter Wall Outlet Electrical Plug
Must Have For Safety
 
GFI Electrical Plugs are required by all USA building codes and are located in your Kitchen, Bath, and Laundry Rooms and other areas close to water sources-
Scotty, Scotts Contracting

All M215 MicroInverters will shut off if there is a fault detected. inside of every microinverter is aGFI (Ground fault detection interrupt) switch and if there is a fault, it will stop exporting power within 30 milliseconds per UL1741 standards. {Scotty Adds- Just Like the GFI electrical plug in your Bathroom and Kitchen works!}

M215 MicroInverter from Enphase Energy
Enphase Energy M215 MicroInverter
Overview

Here’s my conversation with the Good People of Enphase Energy and links to the Articles about the Solar Fire

Scotty:

“Recently in St Louis, MO a solar panel supposedly caught on fire on the roof of a local school…it hasn’t made much news other than deemed solar fire on school. Could one of your Innovative MicroInverters215 sensed the ground fault and stopped the production of electricity and thus eliminated the fire since it would have stopped creating electricity? There is a few local builders who have been considering adding solar but have raised questions in re. Thank you for your time and assistance. Scotty”

Enphase Energy 1st response:

Hello Scotty,
Thank you for contacting Enphase Energy!
That’s a scary situation! Sorry to hear that it happened!
Safety is one of the aspects of our system that we are very proud of. The old style of solar array uses solar panels in series, which ends up with High Voltage DC wiring. Our Microinverters converter the DC to AC right at each panel, which is inherently safer. Here is a link to our informational page that speaks to our safety, which also has a link to PDF:
http://enphase.com/explore/enphase-technology/safe/
Here also is a link to a video demonstration on our YouTube channel, which shows the difference between a DC and AC arc fault:

Scotty:

Thank you for responding to my question.  I’m already a fan of the M215.  Can the M215 sense a ground fault and stop producing electricity?

 “Could one of your Innovative MicroInverters215 sensed the ground fault and stopped the production of electricity and thus eliminated the fire since it would have stopped creating electricity?”

Thank you for your time and assistance.
Scotty 

Enphase Energy (2nd Answer):

Yes! Our Microinverters do detect ground faults and halt production. 
Please let me know if you have any other questions, or if there is anything else I can do to assist. 
Thanks,

Enphase Energy (3rd Answer from Contact Form on their website):

Hi Scotty, 
The inverter will shut off if there is a fault detected. inside of every microinverter is a GDFI (Ground fault detection interrupt) switch and if there is a fault, it will stop exporting power within 30milliseconds per UL1741 standards.

Solar Panel Fire Articles

Solar panels on the roof of Webster Groves High School caught fire today. The fire, which was contained, caused no interior damage. Some water used to put out the fire seeped into a classroom.The cause of the fire has not been determined.

The High School will have classes on Monday.

Like I wrote earlier the Great Minds at Enphase have already factored this safety feature into the Design and Construction of theirInnovative MicroInverter the M215. Couple that with the great and timely feedback from their Websites, Twitter Accounts, and Email Correspondence-

Repairing a Stone or Rock Foundation on Typical StLouis Older Home

Since education of Energy Conservation in building science is ignored by many builders in the region and what I feel is what led to a couple of requests for free estimate for: Spray Foam insulation for Interior Brick Walls on St Louis Brick Home.

I strongly urge everyone who is involved in remodeling, retrofitting, weatherizing, or any other construction related project with a StLouis Building review and practice these must do activities when working on the typical StLouis brick or masonry building.

Improper Building or Retrofitting Techniques could lead to: Respiratory Problems, Indoor Pollution, Combustion from Natural Gas Appliances, as well as the further deterioration of your brick building.

DIY Energy Audits and the A-Hah Moment

In the preceding post on-Less Weight Equals More Horsepower I used the comparison on how the US Automakers figured out how to make our Automobiles use less gas by lightening the vehicles weights which increased horsepower which equates into less Petrol needed for operation and how the same principles can be applied to a Buildings Energy Use and Needs. The principles I will be blogging about applies to any building-Residential or Commercial and can be used to give your Bank Account More Horsepower!

Lets start by going room by room and looking around at all the Gadgets/Appliances that are using electricity. Simple DIY Energy Audits -that anyone can perform on your building. Keep in Mind the Following two bullet points when Inspecting the Gadgets and Appliances.

  • What Gadgets or Appliances in your building are always on and consuming energy? This is Vampire Power [i].
  • Rule of Thumb? “ If your appliances are old enough to Vote it needs replaced with a newer Energy Star Appliance. [ii] ”

Here are examples of my energy use for my buildings for my DIY Energy Audit Home Office Location (Home Office).

I performed a Room by Room walk-thru inspecting taking notes of everything that used electricity. (When I’m performing a Computerized Energy Audit using Equest Software I log the information into the program and it does the math for me plus outlines areas for improvement with ROI for all costs involved.) But we’re going Old School on this Energy Audit and you will only need a basic calculator or pen and notepad.

The Benefits of Performing an Old School Energy Audit by hand and figuring things by hand is the A-Hah Moment of Energy Use- you will gain a greater understanding of:

TYPICAL WATTAGES OF VARIOUS APPLIANCES

Here are some examples of the range of nameplate wattages for various household appliances

  • Aquarium = 50–1210 Watts
  • Clock radio = 10
  • Coffee maker = 900–1200
  • Clothes washer = 350–500
  • Clothes dryer = 1800–5000
  • Dishwasher = 1200–2400 (using the drying feature greatly increases energy consumption)
  • Dehumidifier = 785
  • Electric blanket (Single/Double) = 60 / 100
  • Fans
    Ceiling = 65–175
    Window = 55–250
    Furnace = 750
    Whole house = 240–750
  • Hair dryer = 1200–1875

  • Clothes iron = 1000–1800
  • Microwave oven = 750–1100
  • Personal computer
    CPU – awake / asleep = 120 / 30 or less
    Monitor – awake / asleep = 150 / 30 or less
    Laptop = 50
  • Radio (stereo) = 70–400
  • Refrigerator (frost-free, 16 cubic feet) = 725
  • Televisions (color)
    • 19″ = 65–110

  • VCR/DVD = 17–21 / 20–25
  • Vacuum cleaner = 1000–1440
  • Water heater (40 gallon) = 4500–5500
  • Water pump (deep well) = 250–1100
  • Water bed (with heater, no cover) = 120–380

FORMULA FOR ESTIMATING ENERGY CONSUMPTION-Use this formula to estimate an appliance’s energy use:

  • (Wattage × Hours Used Per Day) ÷ 1000 = Daily Kilowatt-hour (kWh) consumption

1 kilowatt (kW) = 1,000 Watts

Multiply this by the number of days you use the appliance during the year for the annual consumption in kWh per year.

ESTIMATING ANNUAL COST TO RUN AN APPLIANCE

Multiply the annual consumption in kWh per year (that you calculated above) by your local utility’s rate per kWh consumed to calculate the annual cost to run an appliance. Note: To estimate the number of hours that a refrigerator actually operates at its maximum wattage, divide the total time the refrigerator is plugged in by three. Refrigerators, although turned “on” all the time, actually cycle on and off as needed to maintain interior temperatures.

EXAMPLES:

Window fan:
(200 Watts × 4 hours/day × 120 days/year) ÷ 1000
= 96 kWh × 11 cents/kWh
= $10.56/year

Personal Computer and Monitor:
[(120
Watts + 150 Watts) × 4 hours/day × 365 days/year] ÷ 1000
= 394 kWh × 11 cents/kWh
= $43.34/year

What is the Best Defense to fight these upcoming high summertime cooling bills? Energy Conservation is the best defense and will provide the Fastest ROI- Return on Investment for your $Money$.

Little Green Thumb Recycling Adventure

GRATITUDE OF THANKS TO SOUTHERN METAL PROCESSING.

For all my readers who have been reading about my Back-Yard City Garden. I’m sure you have noticed that I’ve had some great help from little green thumbs this year.

Little Green Thumbs helping in the Garden
Little Green Thumbs-Inspecting the Corn Silk on
the Sweet Corn Plants that they helped plant.

Little Green Thumb Recycling Adventure

I try to ‘Lead by Example‘ with the Girls and have been attempting to teach them the benefits of Recycling and becoming a Steward for the Environment. They are already aware of the Blue Recycling Dumpsters in the Alleys and the Recycling Trash Can here at the house. The youngest calls the trips to the Blue Dumpster-“Cycling“.

Yesterday while cleaning out the Garage I compiled all the scrap metal left over from previous projects, loaded it up and headed to Southern Metal Processing on S Broadway in St Louis, MO.

After we were weighed in and unloaded our Scrap Treasures. We were standing in the office receiving our compensation. Unexpectedly Girls were given some Kool toys from the Reward Case. (I personally think the girls have enough toys, especially when I trip over them or am forced to clean them up.) But to a little girl I guess they can never have enough Barbies or Little Pony toys.

The nice lady that gave the girls the toys must understand that there can never be enough toys. She vetoed my suggestion that 1 toy was enough and gave the girls 2 toys each (to the delight of the girls). Thank you’s and hug’s were exchanged and the now very happy girls had Treasures of their own to play with.

I think this is just what is needed from a Business in support of the Green and Sustainable efforts to reduce Global Warming – Climate Change. I can think of no better way to teach the next generation the importance of recycling. And by actions such as these by Southern Metal Processing, (listed SMP on their Trucks). I will bet that the Younger Generations will become better Stewards of our Earth-If this Generation doesn’t kill the Earth first.

Gratitude of thanks to Southern Metal Processing.

Concentrated Solar Power with Heat Recovery Unit Designed by Scotts Contracting 11/01/2011
Updated Concentrated Solar Power Photovoltaic Design with Added

Automatic Heat Recovery Unit for Dual Energy Savings

This is an update on the CSP (Concentrated Solar Power) design with Heat Recovery Unit for added Energy Savings.

Design Features:

  • Energy via the Automatic Heat Recovery Unit

Notes:

  • Many of the CSP designs on the Market today “create steam to generate electricity”.  This design will create electricity efficiently via Photo-voltaic Cells in the receiver; thus eliminating the need for Steam Engines.  It also generates heat to be used in the Heat Recovery Unit (twice as much usable energy for today’s home and business).
  • Heat Recovery Unit incorporates an automatic air handler set by thermostat for transferring climatically controlled air movement.
  • This design works exceptionally well during the winter time when the sun’s radiation is at it lowest radiation level.  Concentrated Solar Power will soon be available for non-desert regions and easily adaptable for any region.

Seeking Assistance to further Develop this CSP Design2.  Please use the Contact Form Below for additional info and Scotty, Scotts Contracting will reply ASAP.
