Testing a power supply at different load currents and different input voltages is important, but it only shows part of the truth. A Bode plot can reveal the rest.

Australia leads world in residential solar per capita with 22GW installed but commercial and industrial sector has deployed only a quarter of that

Australia’s revolution in rooftop solar has left behind commercial and industrial buildings, where installations have lagged far behind homes, according to new analysis.

Australia leads the world in residential solar on per capita terms, with 22GW installed as of last December. But businesses have only installed about a quarter of that – 5.6GW – despite consuming more electricity than households, a report from the Institute for Energy Economics and Financial Analysis (IEEFA) has found.

Australians are world leaders in rooftop solar and home batteries - but greater energy efficiency could make them a triple threat

For David and Ruth Hudspeth, the process of turning their 1950s brick veneer house in Melbourne’s eastern suburbs into a cosy, efficient and fully electric home took several years.

They started with insulation in the ceiling and replacing an old and “pretty dangerous” gas heater. They swapped their leaky hot water system for a heat pump, and built a roof over the outdoor deck for shade and extra solar panels, later adding an electric car and a home battery into the mix.

Just over a year ago, the Trump Administration issued an executive order meant to accelerate the development of nuclear power in the US. While an entire startup ecosystem has developed around the use of different—and typically smaller—reactor designs, only one of them has been fully licensed so far, and there are no plans to actually build any instances of that design.

The executive order directed the Department of Energy to have three different reactor designs reach criticality in a bit over a year. On Thursday, a startup called Antares announced that a test reactor it had placed at the Idaho National Laboratory had reached criticality, making it the first new design to cross this threshold. Criticality means that the nuclear reactions inside the hardware had become self sustaining; it does not mean the reactor had started to generate power.

Antares is one of a number of companies that is basing its design on a new fuel system called TRISO that takes some of the complexity and safety out of the reactor design and places them in the fuel design. The fuel design is based on tiny pellets with a uranium oxide core. The pellets are surrounded by several layers of carbon that can moderate the energy of both the neutrons and lighter nuclei that are released by fission reactions. All of that is encased in a hard ceramic shell that's designed to withstand the highest temperatures that can be produced by the encased uranium.

Last week, as the war in Iran continued to choke global oil supplies, the UK government announced a 13% increase in the cap on energy prices. But it was another related story on the other side of the world that caught my eye.

In Australia, the energy minister announced a fall of up to 10% in the benchmark electricity price in parts of the country, driven by record levels of renewables and batteries in the power grid.

Numerous UFO sightings, particularly near nuclear sites, raise questions about their purpose. Some suggest these crafts harvest energy from power stations, connecting spiritual dimensions with our physical realm. Historical data supports a correlation between UFOs and nuclear facilities, leading to speculation about their energy needs and where they come from.

The COVID-19 pandemic and “safe and effective” vaccines are lies propagated by governments and “experts”. Many widely accepted scientific beliefs are false narratives based on Satan’s lies. Spiritual deception underlies many societal misconceptions. We must return to the foundation of biblical truths from creation to what is real science.

The biblical creation narrative is foundational to understanding reality. It highlights the role of God as the creator and sustainer of both physical laws and spiritual renewal through Jesus Christ.

In this presentation I discuss the drastic reduction in human lifespans after the global flood, from 910-970 years to about 70 years. I link these changes to factors such as biological decay, genetic entropy, Earth’s altered magnetic field and loss of physiological resilience. Eternal lifespans can only be restored through Jesus Christ.

Maxwell Chikumbutso's claim of a "free energy" vehicle powered by radio frequency energy, contradicts established physics, particularly the laws of thermodynamics. All forms of energy involve costs. Chikumbutso provides no evidence to support his "free energy" from radio-waves claim. It is foolish to believe in unverified revolutionary energy solutions.

The generation and evolution of electricity is discussed, highlighting significant milestones from early static electricity experiments to modern AC power generation techniques. Dirty electricity, characterized by high-frequency electrical noise, can lead to health issues. There is a strong need for more research on this electromagnetic pollution and its health impacts.
