Aloha,
I appreciate your consideration of our testimony opposing the 2045 General Plan.While our
elected officials reap their salaries, our volunteer commissioners are left to bear the brunt of
the backlash.As President Franklin D. Roosevelt once said, "nothing happens in politics by
accident." If something occurs, it is because it was planned that way.
We are under siege from attacks that provide their perpetrators with as much plausible
deniability as possible, often attributing these events to natural disasters or climate change.
While these factors play a role,they are being exploited with manufactured weather to target
specific areas. The edges and outskirts are being demolished. The results are devastating: dry
climates,floods,wildfires,water shortages, and homelessness. Our leaders and department
heads offer only apologies,failing to take meaningful and protective action.
Conspirators succeed because we struggle to accept that some may wish to harm their fellow
citizens.We must look around and plan ahead to protect ourselves.
Lawsuits have already shown that smart meters cause fires,yet they are ubiquitous across our
islands.Who benefits from these technologies:the public or the "shareholders", as hinted at in
the 2045 General Plan?There's a push to force us out of our homes and off our lands.We must
investigate weather modification programs,smart meters, lithium batteries, and 5G cell
towers, along with the bills and laws promoting a global agenda at the expense of local
communities.
Notably, low sound frequencies can extinguish fires.A blast of 30 to 60Hz bass can effectively
put out fires, leaving no environmental trace. Drones equipped with such capabilities could be
invaluable in hard-to-reach areas.Why aren't they being used if water is truly scarce?
What harm would come from pausing the 2045 plan to allow further investigation and input
from the local community? Most testifiers are happy to operate under the 2005 plan until
further discovery. If we find value in our discoveries,we can promote positive change. It's
about staying informed and making wise decisions, not blindly accepting potentially harmful
technologies, land grabs, and mandates that ultimately cause the people great harm.

Fires Extinguished with Sound Waves
Several demonstrations and experiments have shown the potential of
extinguishing fires using specific sound frequencies. Here are a few notable
examples:
Charles Kellogg(1926):A naturalist demonstrated extinguishing a gas
flame using tonal vibrations produced by a large bow across an aluminum
tuning fork.This method produced a screeching sound that could extinguish
flames, suggesting that specific sound frequencies could disrupt
combustion processes.
DARPA's Instant Fire Suppression (IFS) Program (2012):The Defense
Advanced Research Projects Agency (DARPA) showcased a system capable
of extinguishing flames using sound waves.This project aimed to
understand the potential of sound waves in military applications and
demonstrated the effectiveness of low-frequency sound waves in
suppressing fires.
George Mason University Students (2015): Seth Robertson and Viet Tran,
engineering students at George Mason University, developed a handheld
extinguisher that uses low-frequency sound waves to put out fires.Their
prototype, costing around$600, uses an amplifier and a cardboard
collimator to focus the sound waves, effectively extinguishing small,
alcohol-fueled fires.
These demonstrations underscore the immense potential of sound frequencies,
particularly low frequencies, in extinguishing fires by disrupting the combustion
process and separating fuel from oxygen.This is not just a theory, but a tangible
possibility that could revolutionize fire safety.

Abstract-
The need for innovation and modernization in fire extinguishing techniques is extremely necessary.Accidents caused
due tofire are disastrous and can lead to irreversible losses. With the rising amount of dangers to the environment in
various aspects, it is essential to avoid as much damage as possible. The existing techniques have been created
considering only their efficiency in extinguishing fires and not considering the harms they can cause to the
environment. Another area of concern is the disasters caused by fire accidents in space. The use of traditional
chemical extinguishers in space is necessary to be avoided as much as possible.Study shows that sound waves could
be one of the potential alternatives for extinguishing fires. Research is necessary in the development of a similar
practical method of fire extinguishing and analyzing which frequency of sound waves gives optimum results. A
possible reason for the flame extinguishment due to sound waves can be that the continuously altering high and low
pressure waves when coupled with high airflow velocity cause disruptions in the air fuel ratio at the flame boundary
which leads to diminishing ofthe boundary.
