Non toxic solar 2 (1)
Researchers at the University of Cambridge have demonstrated that bismuth could provide a non-toxic alternative to lead in low-cost solar cells. Bismuth oxyiodide is a stable, defect-tolerant material that can convert light to electricity with efficiencies of up to 80%. It has the potential to replicate silicon's electronic properties at lower production costs than silicon or lead-based solar cells. While further improvements would be needed, bismuth oxyiodide shows promise as a safer, more efficient solar cell material that could enable the development of next-generation solar technologies.
Nuclearbattery 160307125636
Nuclear batteries are devices that use energy from the decay of radioactive isotopes to generate electricity. They have no nuclear chain reaction and produce no radioactive waste. The technology began in 1913 and was further developed in the 1950s for uses in small electronics. There are three main types: thermionic converters, radioisotope thermoelectric generators, and betavoltaic cells. Betavoltaic cells directly convert the ionization of electrons from beta particle emission into electricity using a semiconductor. Nuclear batteries have advantages of being reliable, compact, and long-lasting power sources, but also have high costs and safety risks. They have applications in space, automobiles, medicine, and underwater devices.
Solar hybrid panel
Researchers have designed new hybrid solar panels that can generate electricity from both sunlight and raindrops. The panels use a triboelectric nanogenerator and graphene materials to produce energy when raindrops land on the surface. When it rains, positive ions separate from raindrops and interact with negative ions in the graphene to create electricity like a pseudocapacitor. This innovation allows solar energy to be harnessed even when the sun is obscured by clouds. Currently, prototypes have an efficiency of around 13% for sunlight and 6% for raindrops, but further research aims to improve performance to levels comparable to traditional solar cells. The hybrid design could make solar power more viable year-round
5 major developments in the field of solar
The document summarizes 5 major developments in solar energy technology from 2010 to 2021:
1. Floating solar farms, also called "floatovoltaics", which place solar panels on reservoirs and water bodies for greater efficiency.
2. BIPV solar technology that integrates solar panels into building designs as roofs, walls, and facades rather than adding them as a separate system.
3. Solar skins, a thin film technology that allows custom images to be displayed on solar panels without reducing efficiency.
4. Solar fabric that embeds solar fibers into clothing to generate energy while on the move.
5. Photovoltaic solar noise barriers that combine noise reduction infrastructure with solar energy
Project Octopus : An innovative Electricity Generation Approach
This document proposes a new concept called Project OCTOPUS for generating pollution-free electricity from sea waves. It notes that current power sources rely heavily on fossil fuels which are being depleted and increasing in cost. Project OCTOPUS utilizes the thrust power of sea waves using floating pods connected in series or parallel that can be scaled up or down as needed. It has several advantages over other renewable energy sources like lower costs, predictability, scalability and adaptability. The prototype shown suggests it can generate electricity more efficiently and at significantly lower costs than thermal, nuclear, hydel or solar power projects currently used.

Repurposing of west virginia strip mines for sustainable
This document discusses potential options for repurposing a former strip mine in West Virginia called Hobet Mine for sustainable energy production. Three main solutions are analyzed: hydroelectric, solar, and wind turbines. For the hydroelectric solution, constructing an upper and lower reservoir with a 300 foot elevation difference could generate 438 MW at an estimated cost of $480 million. A solar farm occupying 2400 acres of the site could generate 150 MW at an estimated capital cost of $166 million. Wind turbines placed on 1800 acres could generate 132GW through 24 turbines, but at a high estimated cost of $234.9 million. Based on metrics analyzing energy output, cost per kW, environmental impact, and social factors, hydroelectric production was determined
Power generation transmission & distribution
This document discusses electric power generation, transmission, and distribution. It explains that electricity can transform lives both economically and socially. It then outlines the different sources used for power generation including fossil fuels like coal and natural gas, as well as renewable sources like hydro, solar, wind, and geothermal. The document also discusses how power is transmitted from generation plants through overhead and underground transmission lines, and then distributed to consumers through distribution lines.
Transparent solar panels
Researchers at Michigan State University have developed transparent solar panels that could be used as windows or in other transparent applications. The solar panels use luminescent solar concentrators that absorb near-infrared light and re-emit it as visible light to solar cells on the edges of the panels, allowing light to pass through the panels while still generating electricity. This breakthrough could enable the installation of solar panels in places traditionally not feasible due to non-transparent panels blocking light.
CSPI Presentation July11
This document proposes a thought experiment on how solar and wind energy could rapidly stop global warming and end imported oil through a full-throttle adoption approach over the next 15 years. It suggests combining solar and wind resources on shared transmission lines, starting in the US Southwest and Midwest, to provide over 3000 TWh of carbon-free electricity annually. This could allow electrification of transportation to eliminate the need for imported oil while lowering CO2 emissions. The plan estimates it could cost around $2.5 per gallon of gasoline equivalent and save money compared to coal. Some challenges mentioned include validating growth rates and ensuring sufficient transmission capacity and smooth output.

Ramdev hopes to convince the MTA directors to purchase electricity from the proposed tidal project.
Talk_Budapest_for Greensolar Management 3rd_July_2013-1
The document discusses the history and future prospects of thin-film silicon solar cell technology. It notes that thin-film silicon was chosen in 1985 by the PV Lab Neuchâtel due to silicon being abundant, non-toxic, and allowing for lower cost production compared to wafer-based silicon cells. Key developments included introducing microcrystalline silicon in 1993 and the "micromorph" tandem cell in 1994. While the technology was adopted widely, the solar industry faced crises in 2008-2009 with companies like Solyndra and Uni-Solar declaring bankruptcy. However, the document concludes that thin-film silicon will remain competitive for niche applications and have opportunities again when nuclear power is replaced and energy payback time becomes more important.

Solar power converts sunlight into electricity directly using photovoltaics or indirectly using concentrated solar power. Concentrated solar power uses lenses or mirrors to focus sunlight into a small beam. In 1839, French physicist Edmond Becquerel discovered the photovoltaic effect while experimenting with a cell made of electrodes in a conducting solution. While regular electricity must be paid for indirectly from power plants, solar power provides access straight from the sun and is often more cost-effective than fossil fuel options according to the World Economic Forum. China is currently the largest producer and consumer of solar energy in the world, with its solar capacity expected to double to 370GW by 2024.

The Amazing Drinking Bird
The document describes the drinking bird toy, which was designed in 1945 by Miles V. Sullivan. It is made of glass with a tube running through two bulbs that form the head and stomach. When the bird is dipped in water, the water evaporates off the beak, cooling the head and causing methylene chloride to condense in the head bulb. This difference in vapor pressure causes the liquid to rise back up the tube, tipping the bird over to "drink" again in a repeating cycle. The drinking bird demonstrates the scientific principles of evaporation and condensation.

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
