“”I saw this signal injector kit so I built my modified version of it on a PCB. Notice that they used two PNP transistors and a positive ground, presumably to get pulses that were positive going. I used an astable multivibrator with negative ground like normal and I changed the output transistor to a PNP, 2N4403. This also gives positive going pulses. The pulse rep rate is about 2.8 kilohertz. The current drain on the 3V (two AA cells in series) is 0.24 milliamp. That’s low enough to use a CR2032 coin cell for the supply voltage. The small value output coupling capacitor makes the pulse very differentiated, in other words its width is narrow. I put a 0.1 microfarad capacitor in parallel with the 470 picofarad and it sounds a lot better using an earphone. The 470 picofarad by itself is barely audible and it’s just a hiss.

Update: I changed the output coupling capacitor from 470 pF to 3.9 nF.
I changed the .0047 uF to .01 uF.””

“”A study published in the journal Joule found that switching to renewable energy could save the world at least $12 trillion by 2050, compared with continuing to rely on fossil fuels. The analysis concluded that a rapid transition to clean energy would not only reduce overall energy system costs, but also deliver more energy to the global economy and expand energy access worldwide.

The researchers found that the costs of solar power, wind energy, battery storage, electric vehicles, and green hydrogen have fallen much faster than many traditional energy models predicted. As these technologies continue to scale up, their costs are expected to decline even further, making clean energy increasingly competitive with fossil fuels across more sectors of the economy.

According to the study’s fast transition scenario, a largely fossil free global energy system by around 2050 could provide about 55% more energy services than today while lowering long term energy costs. The findings challenge the long standing belief that moving away from fossil fuels would be more expensive than maintaining the current energy system.

The study also highlights that renewable energy can help reduce exposure to volatile fossil fuel prices, strengthen energy security, and support global climate goals.🌍⚡

2026-05-21 On May 20, 2026, the UN General Assembly voted to support an opinion issued by the International Court of Justice – governments are obligated to address climate change

“”On May 20, 2026, the United Nations General Assembly voted 141 to 8 to support a historic opinion issued by the International Court of Justice, the world’s highest court. The opinion states that governments have legal obligations under international law to reduce greenhouse gas emissions, address climate change, and protect people from its growing impacts.

The landmark opinion was originally delivered by the court in July 2025. It affirmed that countries must cooperate to achieve meaningful emissions reductions and that failing to meet climate obligations could, in some cases, lead to legal consequences. The court also emphasized the need for stronger action to limit global warming and reduce reliance on fossil fuels.

The decision could have far reaching consequences worldwide. It may strengthen climate lawsuits against governments, increase pressure on countries to adopt more ambitious climate policies, accelerate investments in renewable energy, and encourage faster emissions cuts. Legal experts also say it could support future claims from communities and nations seeking accountability for climate related damages.⛽🚫””

2026-05-16 France, Agrivoltaics Farm, 2400 Hectares, 500 MW, Reduces Crop Water Needs By 30%

Quote

“”France just completed the world’s largest agrivoltaic trial — installing solar panel canopies above 2,400 hectares of Provence vineyards, cereal fields, and vegetable plots, generating 500 megawatts of clean electricity from the same land producing full agricultural output.

The Sun’Agri program installs tilting solar panels on 5-meter-tall structures above crops, with panel angles controlled by sensors responding to crop water stress and solar irradiance. Panels tilt to provide shade on hot days, reducing crop water needs by 30 percent and heat stress damage by 64 percent during heatwaves while generating electricity from diffuse light above the canopy. Crop yields in pilot vineyards increased 27 percent in drought years.

France loses 18,000 hectares of agricultural land to conventional ground-mounted solar annually. Agrivoltaics eliminate this conflict entirely — 2,400 dual-use hectares replace lost food production while generating clean power.

2026-05-11 France Nukes Back Online After Major Emergency Maintenance

blog Consumer Information generation newsmedia Nuclear Power
on May 11th, 2026 by - No Comments

“”France has restarted its entire nuclear fleet after emergency maintenance …

The years 2022 and 2023 were the most difficult in the recent history of French nuclear energy. An unprecedented wave of stress corrosion cracking discovered in the cooling circuits of multiple reactors forced simultaneous outages across a large fraction of the fleet …

EDF’s industrial recovery program … systematically inspected, repaired, and restarted the affected reactors over an 18-month period. By late 2023, the French fleet was back above 80% availability. By 2024, it was approaching historical norms of 85 to 90% availability. …

The stress corrosion episode taught French nuclear operators lessons about inspection frequency, material selection, and maintenance planning that have been incorporated into revised operating protocols. The fleet that has emerged from the crisis is better monitored, more thoroughly inspected, and operated with greater margins against material stress than at any previous point in its history.

France’s nuclear fleet went through its hardest years. It came out stronger.

Source: EDF & French Nuclear Safety Authority (ASN), 2024″”

This is the first that I have heard about this French nuclear plants issues and shutdowns — it’s been more than 3 years! It seems to me that the nuclear industry has tried to keep it quiet — it is a black eye on the nuclear industry as a whole. This disappoints me because the public needs to be kept informed. Of course the NIMBYs will make a big thing about it. But even so, that’s the point of news media – to keep the public informed. This problem – cracks in the cooling system – was what happened with the San Onofre nuclear reactors and they shut them down and spent a hundred million to replace the cracked cooling system. But then it happened again! So they gave up and permanently shut San Onofre down and it is costing hundreds of millions of dollars to decommission San Onofre nuclear.

2026-05-08 California’s Giant Battery Network Now Matches The Output Of 12 Nuclear Power Plants

Battery or Cell blog Consumer Information Energy storage newsmedia rechargeable
on May 8th, 2026 by - No Comments

“”California’s growing battery storage network has reached a major milestone after delivering more than 12,000 megawatts of electricity to the state’s grid, an amount roughly equal to the output of 12 large nuclear power plants.

The record was quietly set in late March as battery systems supplied more than 40 percent of California’s electricity demand at one point during the day. The achievement highlights how large-scale battery storage is increasingly becoming a central part of the state’s energy infrastructure rather than simply acting as backup support, according to a report by Inside Climate News.

California has spent years rapidly expanding grid-connected battery systems, particularly to help solve one of renewable energy’s biggest challenges. Solar power generation typically drops in the evening just as electricity demand rises when people return home, use appliances, and charge electric vehicles. Traditionally, natural gas plants filled that gap.””
