How to Make Electricity From Radio Waves Updated April 25, 2017By Eli Laurens Radio waves, both natural and man-made, contain electrical energy you can tap using simple solid-state hardware. Radio wave collectors use long, insulated copper wire antennas to drive current to a load-bearing device (cell phone charger, battery, light bulb). The electricity collected can be from a radio station or the Earth’s own magnetosphere (our planet’s magnetic field), depending on the length of the antenna and circuitry involved. (Some “crystal radio” experiments use the radio station’s power to drive a small speaker.) The average backyard experimenter can make electricity from radio waves in about 1 hour.
El vuelo arácnido o ballooning (del inglés, pronunciado baluning) hace referencia a un modo de transporte por los aires que ejercen algunas arañas empleando un sistema compuesto por hilos de seda de araña.1 Es una técnica de dispersión que favorece la supervivencia de la especie evitando la combatividad de los depredadores.1 En algunos casos las arañas llegan a ser transportadas cientos de kilómetros.2, 3

El fuego de San Telmo o Santelmo es un meteoro ígneo que consiste en una descarga de efecto corona electroluminiscente provocada por la ionización del aire dentro del fuerte campo eléctrico que originan las tormentas eléctricas. Estaba considerado como un buen augurio por los marineros españoles durante la conquista de América.1

REVIEW Could you create an electric magnetic that used the earth’s magnetism to fly? Yes, with conditions. First, the amount of weight you can lift is very small. It is a product of the strength of your vehicle’s field times the strength of the Earth’s field. The Earth’s field is very weak, only about 40,000 nanoteslas. You would need enormously strong fields in your vehicle. There is another problem. You can only travel along the field lines. If you were at the north magnetic pole you could go straight up and down but not sideways. If you were at the equator you could go north and south but not up/down or east/west. If you were at the North Pole, your craft could be attracted to go straight down into the ground by leading with the south pole of your magnetic craft. This is the only stable configuration. Trying to point a north pole of your craft at the north pole would not push you towards the south pole it would only spin you around and attract the south pole of your ship. If you were at 45° north, the north pole would attract your magnet into the ground but also to the north. If you were on wheels on the ground you could drive due north. Don’t try going south, you will only get spun around. At the equator you can only align with the field. You cannot go north or south as you are equally attracted to both of them. All field lines are parallel there.
Can we light a bulb just by using magnetic field? Yes, easiest way is if the light bulb is made of an ampule filled with a ionizable gas. Once the magnetic field gets strong enough, the bulb will light up momentarilly with no need for any electrical connection to anything else. But remember that if you want the bulb to stay on, then the magnetic field must change its intensity quite rapidly; and remember also that there is no way to get only a magnetic field without the corresponding electrical field
Updated on: Sunday, May 30, 2021, 11:00 AM IST #ArrestBillGates: Here’s why Indians are enraged at Gates Foundation FPJ Web Desk On Sunday, widespread criticism of Microsoft founder Bill Gates began on Twitter in India with the #ArrestBillGates. Gates is being accused of funding a programme in 2009 of testing and sterilizing indigenous vaccines on tribal children via his NGO Bill and Melinda Gates Foundation (BMGF).
The Free Press Journal is an Indian English-language daily newspaper that was established in 1928 by Swaminathan Sadanand, who also acted as its first editor. First produced to complement a news agency, the Free Press of India, it was a supporter of the Independence movement. It is published in Mumbai, India.
Why Are Indians So Angry at Bill Gates?
The latest backlash against the Gates Foundation in India is the result of years’ worth of concerns raised by human rights activists and civil society.By Akshay TarfeJune 15, 2021 This is not the first time the BMGF or Bill Gates has been at the receiving end of public anger in India. This latest outburst is part of constantly growing anger against Gates and his foundation in India. As early as April 2021, Gates received flak for expressing his reluctance about sharing COVID-19 vaccine technologies with developing countries like India. After severe public criticism in India and abroad, BMGF Chief Executive Officer Mark Suzman officially supported a temporary waiver on vaccine IP.

Compulsory sterilization
Compulsory sterilization, also known as forced or coerced sterilization, is a government-mandated program to sterilize a specific group of people. Compulsory sterilization removes a person’s capacity to reproduce, usually through surgical procedures. Several countries implemented sterilization programs in the early 20th century.[1] Although such programs have been made illegal in most countries of the world, instances of forced or coerced sterilizations persist.
Rationalizations for compulsory sterilization have included population control, gender discrimination, limiting the spread of HIV,[2] “gender-normalizing” surgeries for intersex people, and ethnic genocide. In some countries, transgender individuals are required to undergo sterilization before gaining legal recognition of their gender, a practice that the United Nations Special Rapporteur on torture and other cruel, inhuman or degrading treatment or punishment has described as a violation of the Yogyakarta Principles.[3]
Affected populations
Governmental family planning programs emerged in the late 19th century and have continued to progress through the 21st century. During this time, feminists began advocating for reproductive choice, but eugenicists and hygienists were advocating for low income and disabled peoples to be sterilized or have their fertility tightly regulated in order to “clean” or “perfect” nations.[4][5] The second half of the 20th century saw national governments uptake of neo-Malthusian ideology that directly linked population growth to increased (and uncontrollable) poverty, which during the embrace of capitalism, meant that countries were unable to economically develop due to this poverty.
Much of these governmental population control programs were focused on using sterilization as the main avenue to reduce high birth rates, even though public acknowledgement that sterilization made an impact on the population levels of the developing world is still widely lacking.[6] Early population programs of the 20th century were marked as part of the eugenics movement, with Nazi Germany’s programs providing the most well-known examples of sterilization of disabled people, paired with encouraging ethnic Germans who fit the “Aryan race” phenotype to rapidly reproduce.[7] In the 1970s, population control programs focused on the “third world” to help curtail over population of poverty areas that were beginning to “develop” (Duden 1992).
In May 2014, the World Health Organization, OHCHR, UN Women, UNAIDS, UNDP, UNFPA and UNICEF issued a joint statement on “Eliminating forced, coercive and otherwise involuntary sterilization”. The report references the involuntary sterilization of a number of specific population groups. They include:
- Women, especially in relation to coercive population control policies, and particularly including women living with HIV, indigenous and ethnic minority girls and women. Indigenous and ethnic minority women often face “wrongful stereotyping based on gender, race and ethnicity”.
- Funding of mothers on welfare by HEW (Health, Education, and Welfare) covers roughly 90% of cost and doctors are likely to concur with the compulsory sterilization of mothers on welfare.[8] Threats to cease welfare occur when women are hesitant to consent.[8]
- Disabled people, often perceived as asexual. Women with intellectual disabilities are “often treated as if they have no control, or should have no control, over their sexual and reproductive choices”. Other rationales include menstrual management for “women who have or are perceived to have difficulties coping with or managing menses, or whose health conditions (such as epilepsy) or behaviour are negatively affected by menses.”
- Intersex persons, who “are often subjected to cosmetic and other non-medically indicated surgeries performed on their reproductive organs, without their informed consent or that of their parents, and without taking into consideration the views of the children involved”, often as a “sex-normalizing” treatment.
- Transgender persons, “as a prerequisite to receiving gender-affirmative treatment and gender-marker changes”.
The report recommends a range of guiding principles for medical treatment, including ensuring patient autonomy in decision-making, ensuring non-discrimination, accountability and access to remedies.[2]
As a part of human population planning
Human population planning is the practice of artificially altering the rate of growth of a human population. Historically, human population planning has been implemented by limiting the population’s birth rate, usually by government mandate, and has been undertaken as a response to factors including high or increasing levels of poverty, environmental concerns, religious reasons, and overpopulation. While population planning can involve measures that improve people’s lives by giving them greater control of their reproduction, some programs have exposed them to exploitation.[9]
In the 1977 textbook Ecoscience: Population, Resources, Environment, authors Paul and Anne Ehrlich, and John Holdren discuss a variety of means to address human overpopulation, including the possibility of compulsory sterilization.[10] This book received renewed media attention with the appointment of Holdren as Assistant to the President for Science and Technology, Director of the White House Office of Science and Technology Policy, largely from conservative pundits who have published scans of the textbook online.[11] Several forms of compulsory sterilization are mentioned, including the proposal for vasectomies for men with three or more children in India in the 1960s,[12] sterilizing women after the birth of their second or third child, birth control implants as a form of removable, long-term sterilization, a licensing system allotting a certain number of children per woman,[13] economic and quota systems of having a certain number of children,[14] and adding a sterilant to drinking water or food sources, although the authors are clear that no such sterilant exists nor is one in development.[15] The authors state that most of these policies are not in practice, have not been tried, and most will likely “remain unacceptable to most societies.”[15]
Holdren stated in his confirmation hearing that he no longer supports the creation of an optimum population by the U.S. government.[16] However, the population control policies suggested in the book are indicative of the concerns about overpopulation, also discussed in The Population Bomb a book written by Paul Ehrlich and Anne Ehrlich predicting major societal upheavals due to overpopulation. As this concern about overpopulation gained political, economic, and social currency, attempts to reduce fertility rates, often through compulsory sterilization, were results of this drive to reduce overpopulation.[17] These coercive and abusive population control policies impacted people around the world in different ways, and continue to have social, health, and political consequences, one of which is lasting mistrust in current family planning initiatives by populations who were subjected to coercive policies like forced sterilization.[18] While population control policies have been widely critiqued by women’s health movement in the 1980s and 1990s, with the International Conference on Population and Development in 1994 in Cairo initiating a shift from population control to reproductive rights and the contemporary reproductive justice movement.[19][20] However, new forms of population control policies, including coercive sterilization practices are a global issue and a reproductive rights and justice issue.[21]
