#DIY Seasonal Mirror-Based #WindowExtender for Heat and Light
via @LabB
"The core concept is that, by mounting a mirror roughly perpendicular to the bottom of a south-facing window, it reflects sunlight that would have fallen on the insulated exterior of the building through the window instead. With the right sized mirror and mounting hardware, the functional 'size' of the window for solar gain calculations could be increased by almost 50%, potentially providing Burlington, Vermont windows with Boulder, Colorado performance!"

11 #OffGridCommunication Methods: Staying Connected in Emergencies and Remote Areas
September 18, 2023
"In today's digital age, staying connected is often taken for granted. We rely heavily on our smartphones and the internet to keep in touch with loved ones and access vital information. However, in emergency situations or remote areas where traditional communication methods may become unreliable or fail, it is essential to have alternative means of staying connected. Off-grid communication techniques offer a lifeline for individuals to communicate with others and seek help when needed.
Here are five reliable and realistic off-grid communication methods that let you have a conversation like you would on a cell phone when your cell is down for the count:
1. Ham Radio: Making Connections, No Matter the Distance
When it comes to off-grid communication, few methods can match the power and versatility of ham radios, also known as amateur radios. Ham radios work by transmitting and receiving signals through antennas.
Their range of communication can vary depending on factors such as frequency, antenna height, atmospheric conditions, and obstacles like buildings or terrain. In optimal conditions, ham radios can communicate over hundreds of miles, potentially even globally. Ham radios are beneficial for emergency communication and can provide a means of staying in touch with others during natural disasters or in remote wilderness areas. It is important to note that obtaining a license and some technical knowledge is necessary to operate a ham radio legally and effectively.
When traditional infrastructure falters, or in off-grid scenarios where traditional cellular networks are inaccessible, ham radios prove their worth as a reliable means of communication.
2. CB Radio: Keeping Your Group Connected
For those looking for a simple and accessible option, CB radio comes to the rescue. Citizens Band radio, or CB radio, operates on a set of 40 channels and does not require a license to use. It is a simple and effective off-grid method that offers a reliable means of communication within a localized area. CB radios are commonly used by truck drivers, outdoor enthusiasts, and emergency responders. CB radios work by transmitting and receiving radio signals using handheld devices or mounted units in vehicles.
While their range is shorter compared to ham radios, typically reaching a few miles, CB radios still prove effective for staying connected with your group while exploring remote areas or during emergencies when cellular networks go down. With their simplicity and ease of use, CB radios ensure you'll be able to communicate when it matters most.
3. Satellite Phone: Communication Without Boundaries [Note: Will not work after #KesslerSyndrome events]
When you find yourself in areas without cellular coverage, satellite phones step in to bridge the gap. By connecting to orbiting satellites, these devices provide global coverage, allowing you to make calls and send messages from virtually anywhere on the planet.
Whether you're exploring remote regions or facing emergencies in areas lacking traditional infrastructure, satellite phones become invaluable tools for staying connected. It's worth noting that satellite phones may come with a higher price tag compared to other options, but their ability to keep you in touch with the world makes them well worth the investment.
4. Walkie Talkies: Portable and Practical Communication
If you're looking for a portable and practical off-grid communication solution, look no further than walkie talkies. These handheld devices provide short-range communication through radio waves. They are simple to use and do not require any licensing.
Walkie talkies work by transmitting and receiving radio signals between two or more devices. The range of communication for walkie talkies typically varies based on factors such as terrain, obstacles, and the power of the devices. In general, walkie talkies can provide effective communication in the range of a few miles, making them ideal for coordinating activities within a group or staying in touch during outdoor adventures. Walkie talkies are commonly used by hikers, campers, and event organizers, enabling quick and reliable communication in off-grid situations.
5. Mesh Networking Devices: Building Connections Without Infrastructure
When traditional infrastructure is unavailable, mesh networking devices step in to establish connections where none exist. Devices like goTenna or Sonnet create peer-to-peer networks, forming a web of interconnected devices. They create a decentralized network by linking multiple devices together, with each device acting as a "node" or connection point that can directly communicate with nearby devices.
It's important to note that the range of mesh networking devices depends on factors such as the number of devices in the network and the surrounding terrain. These devices excel in situations where communication becomes difficult due to the lack of infrastructure.
Two "One Way Street" Options
Sometimes, off-grid communication becomes a "one-way street" situation where you either need to receive or send critical information without engaging in a full-blown conversation. Two options that fit this scenario are shortwave radios and GPS messenger beacons.
Shortwave radios provide up-to-the-minute information during emergencies, even when cell phone towers fail. As seen in the case of the Maui fires, communication failures left people without a way to get in touch with loved ones, and critical cell phone alerts went undelivered. In such scenarios, shortwave radios can provide reliable and up-to-the-minute information, potentially saving lives.
GPS messenger beacons, on the other hand, allow users to send distress signals and their precise coordinates to rescue services. This enables quick and targeted assistance in emergency situations, even when direct communication is not possible.
Four Low-Tech Off-Grid Communications Techniques
Off-grid communication doesn't have to be high-tech to be effective. The classic survival movie scene of building a roaring fire on a deserted island/remote mountain/in a dense jungle to signal for rescue is a cliche for a reason and speaks volumes of the power of low-tech and no-tech methods to communicate the need for help. From #SmokeSignals to #flares to #mirrors to #whistles, resources as simple as these can help save the day. These low-tech visual and auditory signaling techniques can be highly effective in emergencies when you simply need to be spotted or heard.
Bottom Line: Off-Grid Communication Methods can be a Critical Lifeline
Mastering off-grid communication techniques is vital for increasing self-reliance and preparedness in emergency situations and remote areas. By understanding and utilizing these methods, individuals and their families can stay connected, seek help when needed, and increase their chances of survival. From a high-tech ham radio or satellite phone to a simple radio and whistle, having a range of off-grid communication tools is an essential part of any emergency preparedness plan."

Very much a prequel of the crazy reflection of the back of Suzon's head a few years later.

I used to teach young #drivers to adjust their three #mirrors—the two door mirrors and the inside mirror—so that the combined field of view not only overlaps with each other but also with the eyes' peripheral vision, thus leaving no #blindspots. While this is very useful on the racetrack, it can be lifesaving on the motorway. Adjust the mirrors as follows:
• Park the car on a piece of flat ground.
• Adjust the seat position so as to accommodate a comfortable driving position.
• Adjust the inside mirror so that the rear window is completely within the mirror's view. (I have never driven an openwheeler, so what I am saying applies only to modified roadcars.)
• To adjust the left door mirror horizontally, lean the head left until the temple just touches the raised window. Then, adjust the door mirror so that its right-edge view just overlaps with the inside mirror's left-edge view. This setting ensures that the left-edge of the door mirror overlaps with the left-side peripheral vision of the eyes, while the in driving position. The left corner of the rear of the car will not be in view.
• Now, adjust the left door mirror vertically so that the far horizon of the ground covers the lower 1/3 of the mirror's view.
• Repeat for procedure for the right door mirror, by leaning the same amount to the right side. Note that this procedure is for left-hand-drive cars; reverse the direction when in right-hand-drive cars.But a lot of drivers adjust their door mirrors so that they could see the tail of their car. This is pointless, for the tail corners of one's own car are not threatening to overtake one.
But then, all new cars today come with side cameras and obstacle warning AI systems. So, ....

Dear Friends of [insert #preferred type], ✔️
Later this #morning, we have a food #delivery bereft of #chocolate. It truly is the end of the #Gaia (as we nose it). Soon we will be swallowing or regurgitating our own tale (ouroboros style). :thinking_ie:
Meanwhile, as we may know, the #world does not turn around chocolate bars or pork sausages and #beans, which I had for #breakfast. Or indeed each etched #individual. Or does it? :ablobcatgoogly:
According to the elders of the interweb; every #spider has its day and every# wormhole its #centrum.
In other words, have a great day be #kind to your many #reflective spiders, #lobsters, #mirrors and #fallow morons ... eh ... more ONS ... -
