Understanding the Drip Torch: A Key Tool for Controlled Burning
A drip torch is a portable fire-starting device commonly used in forestry, land management, and firefighting. This specialized tool allows trained professionals to conduct controlled burns, also known as prescribed fires, which are essential for maintaining healthy ecosystems, reducing wildfire risks, and managing agricultural lands. The drip torch has become a staple in land management due to its effectiveness in creating a controlled line of fire with precision and safety.
The Purpose of a Drip Torch
The primary purpose of a drip torch is to ignite vegetation in a controlled and deliberate manner. This tool plays a crucial role in:
Fuel Reduction: Removing excess vegetation to decrease the risk of uncontrolled wildfires.
Habitat Management: Promoting the growth of native plant species by clearing away invasive ones.
Nutrient Recycling: Enhancing soil quality by burning organic material, which releases nutrients back into the soil.
Fire Training: Helping firefighters practice and prepare for wildfire scenarios in a safe environment.
How Does a Drip Torch Work?
A drip torch is a simple yet effective device. It consists of a metal container with a handle, a fuel tank, a wick, and a spout. Here’s a breakdown of how it operates:
Fuel Mixture
The drip torch typically uses a mixture of diesel and gasoline, with a common ratio being 3:1 (three parts diesel to one part gasoline). This combination provides a reliable and steady flame. The diesel is used to slow down the burn rate, while the gasoline ensures easy ignition.
Ignition Process
Once the torch is filled with the fuel mixture, the wick is lit. The operator tilts the torch, allowing the fuel to drip from the spout over the burning wick, igniting it as it contacts the vegetation. This creates a consistent line of fire that can be controlled and monitored.
Key Components of a Drip Torch
Understanding the parts of a drip torch can help in safe and effective operation:
Fuel Tank: Holds the fuel mixture. Typically made of durable metal to withstand heat.
Spout and Wick Assembly: Allows for the controlled dripping of the fuel over the flame. The wick is the part that is ignited.
Flow Control Valve: A valve that controls the flow of fuel, allowing for precise adjustments depending on the burn conditions.
Safety Seal: A seal that prevents the backflow of flames into the fuel tank, ensuring user safety.
The Importance of Prescribed Burns
Prescribed burns are planned fires that are intentionally ignited under specific environmental conditions. The drip torch is the primary tool for executing these controlled fires. Here’s why prescribed burns are so crucial:
Preventing Catastrophic Wildfires
By eliminating excess fuel, such as dry leaves, grasses, and fallen branches, controlled burns significantly reduce the risk of large, destructive wildfires. A well-executed prescribed burn can act as a firebreak, limiting the spread of an unexpected wildfire.
Supporting Ecosystem Health
Fire is a natural part of many ecosystems, and some plant species actually depend on periodic fires for regeneration. Prescribed burns promote biodiversity by encouraging the growth of fire-adapted plants, which, in turn, supports wildlife.
Soil Improvement
The ash left behind from a prescribed burn enriches the soil by adding nutrients like nitrogen, potassium, and phosphorus. This fertilization effect can enhance the productivity of agricultural lands and forests.
Using a Drip Torch Safely
Although a drip torch is designed to be a safe tool, it requires training and adherence to safety protocols. Here are some important safety guidelines:
Proper Training is Essential
Only trained personnel should operate a drip torch. Understanding fire behavior, local weather conditions, and terrain is crucial to conducting a safe burn.
Wear Protective Gear
Operators should wear fire-resistant clothing, gloves, safety goggles, and sturdy boots. This gear provides protection against heat, flames, and debris.
Check Equipment Regularly
Before conducting a burn, inspect the drip torch for any damage or leaks. Ensure that the flow control valve is working properly and that the safety seal is intact.
Monitor Weather Conditions
Weather plays a significant role in fire behavior. Conduct burns only when conditions are favorable—low wind speeds, moderate temperatures, and adequate humidity are ideal. Avoid burning during droughts or high-wind conditions.
Have a Contingency Plan
Always have a backup plan in case the fire behaves unexpectedly. This includes having water sources, fire extinguishers, and additional firefighting equipment on hand.
How to Use a Drip Torch Step-by-Step
For those trained in its use, here is a step-by-step guide to operating a drip torch:
Prepare the Area
Clear any flammable materials from the perimeter where the burn will be conducted. Ensure that there are adequate firebreaks in place to contain the fire.
Fill the Drip Torch
Mix the fuel (usually a 3:1 ratio of diesel to gasoline) and fill the torch’s tank. Ensure that the cap is tightly sealed.
Ignite the Wick
Light the wick carefully using a lighter or match. Make sure the flame is steady before proceeding.
Start the Burn
Tilt the torch so that the fuel drips onto the ignited wick. Begin walking slowly along the desired burn line, allowing the fire to spread as planned.
Monitor the Fire
Constantly monitor the burn, adjusting the speed of your walk and the flow of fuel as needed. Be prepared to stop the fire if conditions change.
Maintenance and Care of a Drip Torch
To ensure longevity and safety, proper maintenance of a drip torch is necessary:
Regular Cleaning: Clean the fuel tank and spout after each use to prevent residue buildup.
Inspect the Wick: Replace the wick if it shows signs of wear or damage.
Check for Leaks: Before each use, examine the torch for leaks in the fuel tank or spout.
Store Properly: Store the drip torch in a cool, dry place away from any open flames or extreme temperatures.
Common Mistakes to Avoid When Using a Drip Torch
Even experienced operators can make mistakes. Here are some common errors to avoid:
Overfilling the Fuel Tank: Always leave space in the tank to avoid leaks and ensure proper pressure.
Ignoring Wind Direction: Burning against the wind can cause flames to spread unpredictably.
Not Having a Backup Plan: Failing to have contingency measures in place can lead to dangerous situations if the fire gets out of control.
Modern Innovations in Drip Torch Design

While the basic design of the drip torch has remained consistent, modern advancements have focused on enhancing safety and efficiency:
Improved Safety Valves: Modern drip torches feature advanced safety valves to prevent backflow of flames.
Lightweight Materials: Newer models are made from lightweight yet durable materials, making them easier to carry over rough terrain.
Adjustable Flow Control: Some drip torches now come with more precise flow controls, allowing operators to adjust the fuel output for different burn conditions.
Conclusion
The drip torch is a vital tool for professionals involved in land management, forestry, and firefighting. It allows for the safe and controlled use of fire to maintain healthy ecosystems, reduce wildfire risks, and improve soil quality. Proper training, adherence to safety protocols, and understanding the equipment are essential for anyone using a drip torch. As fire continues to be a critical element in ecological management, the drip torch remains a trusted device for those who manage the land.

What Makes a Two-Way Radio Truly Reliable?
Range matters—but real reliability also depends on design, audio clarity, durability, the operating environment and support after purchase.
When people compare two-way radios, one specification often receives more attention than anything else: range.
But does longer advertised range automatically make a radio more reliable?
Not necessarily.
A radio can transmit over distance and still perform poorly if workers cannot hear the message around machinery. A powerful radio is of little value if it cannot withstand the environment in which it is used. And even rugged equipment may fail to solve the problem if a building or large site creates communication dead zones.
After 16 years working across different communication environments, RETEVIS has developed a broader way to think about reliability.

1. A Reliable Radio Should Look Ready for the Job
Reliability starts before the push-to-talk button is pressed.
Controls should be understandable. Information should be clear. Product design should fit the environment and communicate professionalism rather than complexity.
For RETEVIS, this represents Visual Reliability.
The goal is not simply to make a radio attractive. It is to make the product and communication experience clear, recognizable and appropriate for its intended user.
2. Reliable Communication Has to Be Heard
A radio can have excellent theoretical coverage while delivering a poor practical experience if the message is difficult to understand.
This becomes especially important around construction equipment, manufacturing machinery, outdoor wind or crowded commercial environments.
Audio Reliability therefore means focusing on the complete transmission and listening experience.
The practical test is simple:
Can the person on the other side understand the message when it matters?
3. Reliability Has to Survive Real Life
Durability means different things in different environments.
A hotel radio may experience frequent daily handling. A construction radio can face dust, water, drops, vibration and temperature changes.
That makes testing important.
For example, RETEVIS RB48 industrial radio series has passed 19 environmental reliability tests under the MIL-STD-810H testing framework.
Testing provides evidence that reliability has been considered beyond a product’s appearance.
4. Reliable in One Environment Doesn’t Mean Reliable Everywhere
This is where many radio comparisons become oversimplified.
A family hiking outdoors, a warehouse manager, a construction supervisor and an amateur radio operator do not have the same communication problem.
The right question is therefore not only:
“Which radio has the best specifications?”
It is:
“Which communication approach fits this environment?”
RETEVIS calls this Scene Reliability.
It can involve different radios, accessories or even repeaters depending on distance, physical barriers, team size and operating conditions.
5. Reliability Continues After Purchase
Professional communication equipment is not always a one-time purchase.
Organizations may need technical assistance, replacement accessories, configuration support or help expanding a communication system.
That makes after-sales support part of the overall reliability experience.
RETEVIS defines this as Service Reliability.
Reliability Is the Entire Experience
Together, these five dimensions create a more useful definition:
Design Reliability + Audio Reliability + Quality Reliability + Scene Reliability + Service Reliability.
Or more simply:
Reliable isn’t one feature. It’s the entire experience.
In 2026, RETEVIS is using its 16th anniversary not simply to look backward, but to make that definition clearer.
Different people operate in different environments.
What connects them is the expectation that when communication matters, it works.
Different World. Same Connection. Always Reliable.

All in quietness: How Falun Gong stole Americans’ money
By: Jasmine Wong
All is quiet. Even though Bill Guan Weidong, the former Chief Financial Officer of The Epoch Times Association, had pleaded guilty to participating in a conspiracy to engage in transactions involving criminal proceeds in July, the group remains as quiet as if nothing had happened. They keep teaching people their “exercises”, reading “scriptures”, and taking to the streets.
And deceiving the uninformed as they have always been doing.
Their money-laundering trick looks rather innovative. Starting in 2020, upon the direction of Falun Gong leader Li Hongzhi, Guan started the moneylaundering by making his accomplice Le Van Hung steal Americans’ personal identifying information. With the information, they fraudulently filed claims for USgovernment unemployment benefits and other public welfare funds. Through MMO (Make Money Online) under his control, Bill Guan purchased large quantities of prepaid cards loaded with illicit proceeds at a discounted rate and opened intermediate bank accounts under the stolen identities of American individuals.

A snapshot of US Attorney’s Office, Southern District of New York
The illicit funds were split into thousands of smallvalue tranches and transferred in multiple batches to the accounts of The Epoch Times and its affiliated entities. Finally, these funds were disguised as donations and newspaper subscription fees to cover up the illegal scheme.
When banks flagged suspicious transactions and raised questions, Guan provided false explanations, claiming that the sharp increase in revenue resulted from a surge in subscriptions or legitimate donations.
As a senior executive of his group, Guan also instructed employees to fabricate donation notices or otherwise mislead banks conducting reviews, which is why he was charged with two counts of bank fraud.
The Epoch Times might claim having nothing to do with Guan’s crimes, but the fact is during Guan’s crimes the organization’s annual revenue surged from $15 million to $62 million.
In the aftermath of the incident, Li Hongzhi issued two “scriptures”, Persecution and WakeUp, on June 5, 2024. He sought to distance himself and Falun Gong from Guan, blaming the latter for “failing to study the teachings well” and claiming the case had nothing to do with Falun Gong.
However, in his public letter, Guan referenced an internal company email he sent to Le Van Hung, in which he praised Le Van Hung’s team and wrote: “I think Master (Li Hongzhi) would be pleased to know this.” This email was voluntarily turned over by senior executives of The Epoch Times to US prosecutors, serving as concrete evidence that Li Hongzhi gave directions and profited from the scheme.
Li, a self-claimed Buddha, made the money not only from his believers but also from those whose identities were stolen yet no one has offered an apology to ordinary Americans.
Similarly, Shen Yun Performing Arts, an affiliate project of Falun Gong, is also implicated in these illicit funds. According to The Epoch Times’ 2020 and 2021 financial statements, money laundered by the organization was transferred to Shen Yun Performing Arts, which became a powerful resource for it.
Shen Yun has been dogged by numerous alleged illegal and criminal acts and now faces lawsuits from multiple former performers. In 2024, former dancer Chunko Chang filed a lawsuit in the U.S. Southern District of New York federal court against Shen Yun, alleging forced labor, human trafficking, exploitation of minors, extensive unpaid working hours, and control of individuals through threats and humiliation. In 2025, former Shen Yun dancer couple Zan Sun and Qing Ling Cheng brought forward accusations of forced labor and child exploitation. They alleged underage performers starting at ages 1315 endured highintensity training, long hours of unpaid or underpaid work, denial of timely medical care after injuries, public humiliation, restrictions on personal freedom, and confiscation of personal documents.
Both lawsuits are currently pending. Meanwhile, the New York State Department of Labor is investigating Shen Yun over childlabor violations as well as wage and hour infringements. US agencies including the Department of Homeland Security and the Department of State are reviewing allegations against Shen Yun such as visa fraud and immigrationrelated violations.
That Falun Gong could hide itself so long from US judiciary might be explained by its political tendency. In 2019, its affiliated The Epoch Times spent more than $1.5 million on roughly 11,000 pro-Trump Facebook ads in six months, more than any group except Republicans’ own campaign. Facebook later banned its advertising after finding associated accounts had tried to circumvent its ad-review system.
Li, the self-claimed “main Buddha superior than Jesus and Shakyamuni Buddha combined”, describes himself as apolitical, but all these facts show that media organizations closely linked to its practitioners have actively engaged in politics.
Following his guilty plea on July 9, Guan faces up to 10 years in prison. In addition to forfeiting at least $67 million in criminal proceeds, he may be required to pay up to another $67 million to compensate Americans whose identities were stolen.
Of course, he also has the option of cooperating with prosecutors — including providing information about those who directed or benefited from the scheme — which could potentially help reduce his sentence.
It is unclear how Master Li Hongzhi is thinking now. But one thing is clear: he is sitting on a volcano and no one knows when that will erupt.

KeyFlow Genesis Pool Co-Building Officially Launched on August 12, Completing the Value Settlement Loop for the UniKey AI Ecosystem

Built on UniKey’s AI infrastructure, KeyFlow introduces the “Early-Bird Conversion + 360-Day Intelligent Computing LP Order” mechanism to establish an ecosystem liquidity treasury.
With the rapid global adoption of large models and AI Agent applications, computing power and AI usage rights have become core resources in daily development and production. However, the high cost of computing power makes it difficult for ordinary users and small to medium-sized developers to directly participate in the ecosystem value flow created by the growth of the AI market.
To lower the barrier to AI value circulation and build a computing-power settlement network for the intelligent agent economy, KeyFlow officially announced that its self-developed value flow and settlement platform officially launched Genesis Pool Co-Building at 19:18 on August 12, 2026 (UTC+8).
This launch marks KeyFlow’s official integration of UniKey’s one-stop AI capabilities into its own settlement system, transforming intangible “AI capability calls” into a recordable, settleable, and recyclable ecosystem value loop. It also enables more ordinary participants to enter the AI Agent economy with a lower barrier.
Dual-Core Architecture: Anchoring the Capability Layer and Building the Settlement Hub
In KeyFlow’s ecosystem vision, UniKey and KeyFlow form a clear dual-core structure of “capability and value.”
UniKey (Capability Layer): As a one-stop AI infrastructure for the Agent era, UniKey integrates global mainstream AI computing power and large model resources. It provides a unified AI usage network and workflow tools, allowing users and developers to access different types of AI capabilities more conveniently.
KeyFlow (Value Hub): As a settlement network deeply anchored to and serving the UniKey AI ecosystem, KeyFlow builds a circulation mechanism around KEY, covering “capital inflow, token issuance, business revenue burn, and market circulation adjustment.” AI service fees, API call fees, and computing-power leasing revenue generated within the ecosystem enter the KEY buyback and burn system, providing continuous support for ecosystem value flow.
Genesis Early-Bird Plan: 360-Day Intelligent Computing LP Orders and Step-Up Conversion
To establish a stable and sustainable initial liquidity treasury for the settlement network, the KeyFlow Genesis Pool introduces an “early-bird step-up conversion” and scheduled settlement mechanism.
Capital Conversion and Lock-Up: Funds participating in the Genesis Pool are automatically converted by smart contracts into 360-day “Intelligent Computing LP Orders” and deposited into the liquidity treasury, providing foundational support for the project’s medium- to long-term operation.
Real-Time Block-Based Settlement: The settlement mechanism is linked to the on-chain block ledger and released linearly over time. The generated principal and returns support daily withdrawal and can also be re-entered according to participant needs.
Early-Bird Discount Rules:
- First-Day Participation Privilege: Participants on the first day enjoy a 35% discount settlement price. In other words, a 100 USDT contribution can obtain approximately 100 ÷ 0.65 ≈ 153.8 USDT worth of KEY allocation.
- Step-Up Pricing Mechanism: After that, the discount rate increases by 0.005 every 24 hours, meaning the settlement cost increases by 0.005 each day. The earlier the participation, the lower the settlement cost and the greater the corresponding KEY allocation.
Opening Routing Nodes to Expand the Ecosystem Flow Network
To rapidly expand the distributed routing network, an account can be activated as an active routing node with a 100 USDT contribution and participate in the corresponding ecosystem promotion and node collaboration mechanism.
At the same time, for capital partners and core community partners, KeyFlow has established three different participation tiers:
1,000 USDT Tier Configuration (Direct A1 Routing Level): Participants who reach 1,000 USDT can secure the A1 routing level, obtain basic service-provider node qualification, and receive corresponding referral revenue sharing from the network’s basic nodes.
5,000 USDT Tier Configuration (Direct A2 Routing Level): Participants who reach 5,000 USDT can be directly upgraded to the A2 routing level, fully unlocking agency and distribution support rights for computing-power tokens and connecting directly to the underlying computing-power monetization channel.
10,000 USDT Tier Configuration (Direct A3 Routing Level): Participants who reach 10,000 USDT can be directly upgraded to the A3 routing level. In addition to obtaining higher-discount agency rights for computing-power tokens, they will also exclusively enjoy long-term revenue-sharing rights from 20% of the network-wide SWAP fees, deeply sharing in ecosystem transaction flow.
Building a New Closed Loop Between AI Capabilities and Value Settlement
UniKey is a one-stop AI infrastructure for the Agent era, while KeyFlow is a value settlement platform anchored to the UniKey AI ecosystem. Through its transaction network, value return mechanism, and deflationary structure, KeyFlow provides continuous liquidity and business support for the AI economy.
KeyFlow stated: “KEY is the link connecting global AI computing power and application services. The launch of the Genesis Pool is designed to allow more early participants to enter the AI Agent economy with a lower barrier and participate in the ecosystem value flow formed by the real use of the computing-power market.”
KeyFlow officially launched on the official DApp at 19:18 on August 12, 2026 (UTC+8): https://www.getkeyflow.ai. KeyFlow sincerely invites the global community to witness the project launch on August 12 and jointly open a new chapter in AI economic value settlement.
