Segundo uma pesquisa realizada pela Organização das Nações Unidas (ONU), aproximadamente 40% da população mundial sofre com a falta de água.

Pesquisadores criam peneira que transforma água do mar em água potável

Esse grave problema, além de aumentar consideravelmente a sede no mundo, traz graves consequências para economia e política das nações. Foi tentando solucionar esse problema que pesquisadores da Universidade de Manchester, no Reino Unido, desenvolveram uma peneira capaz de transformar água do mar em água potável. Os resultados da pesquisa foram publicados na revista científica Nature Nanotechnology e mostram que a peneira foi criada utilizando o óxido de grafeno (forma cristalina de carbono), substância altamente eficaz na dessalinização.

What is Microhydro Power?

Hydro-electricity is fundamentally the combination of water flow and vertical drop (commonly called “head”). Vertical drop creates pressure, and the continuous flow of water in a hydro system gives us an ongoing source of pressurized liquid energy. Bomba Barsha es capaz de bombear 45.000 litros de agua al día sin combustible. Pratap Thapa ha diseñado una solución eficiente y barata que permite bombear agua sin depender del combustible.

La Bomba Barsha, desarrollada por la empresa holandesa aQysta, de la cual Pratap es cofundador, es una rueda hidráulica que se coloca sobre una plataforma flotante en un río y que utiliza la energía cinética del agua para bombear el agua a través de mangueras. Para su diseño se basaron en tecnologías desarrolladas en el antiguo Egipto.

Su funcionamiento es sencillo, no utiliza ningún tipo de combustible ni electricidad para su funcionamiento, usa la energía cinética del caudal de agua para mover la rueda. Cada vez que la rueda gire recogerá un poco de agua y de aire, y la presión que ejerce ese aire es la que permitirá luego que el agua sea expulsada por las mangueras al campo. The innovators: US scientists harness the power of evaporating water. A small Lego device on the shelf of professor Ozgur Sahin’s office at Columbia University could open up the possibility of another form of renewable energy, and one that is much cheaper than solar and wind.

Sahin has used the simple gadget to prove that evaporating water can be used to generate power, which could eventually lead to energy being generated from still reservoirs. At the centre of the research by Sahin and his team in New York are spores of common soil bacteria that expand, much like a muscle, when there is moisture in the atmosphere, and contract in drier conditions. In 2009, Sahin started to investigate whether there was a practical application to this expansion and contraction. By putting thin layers of the spores on plastic tapes and controlling the amount of moisture in the air, they expand and contract very quickly, creating movement on the tapes.

By putting a large number of tapes together, they produce an energy force that can be captured. Estudantes criam parede que promete substituir ar condicionado. Fonte: Olhar Digital A hidrocerâmica é composta de bolhas de hidrogel que são capazes de reter até 400 vezes o seu volume em água.

Estudantes criam parede que promete substituir ar condicionado

Aparelhos de refrigeração e climatização são comuns em muitas casas em empresas. Estes equipamentos, que ajudam a amenizar o desconforto das altas temperaturas, são responsáveis por grande parte do consumo de energia elétrica, além de contribuírem para a chamada “pegada de carbono”, que mede a quantidade de CO2 produzida diariamente por cada pessoa. Pensando nisso, estudantes do Instituto de Arquitetura (IAAC), na Espanha, criaram um protótipo de parede que promete resfriar o ambiente sem a necessidade destes eletrodomésticos. Nava: A Revolutionary Filtering Water Bottle - GADGETS.feedbox.info. Sistema feito por garota de 17 anos purifica água e gera energia. The Latest Clean Energy Cocktail: Bacteria And Fungus. By Jeff Spross "The Latest Clean Energy Cocktail: Bacteria And Fungus" By throwing together a common fungus and a common bacterium, researchers are producing isobutanol — a biofuel that gallon-for-gallon delivers 82 percent of gasoline’s heat energy.

The more common ethanol, by contrast, only gets 67 percent of gasoline’s energy, and does more damage to pipelines and engines. Central hidroeléctrica casera y económica. Navegando me encontré con este curioso diseño de turbina hidráulica hecha por muy bajo costo y de forma muy sencilla.

Central hidroeléctrica casera y económica

Sam Redfield es el responsable de este brillante diseño donde con un cubo de plástico de unos 20l podría servir uno de pintura por ejemplo, y unas tuberías de PVC junto con un alternador de imanes permanentes como generador eléctrico obtiene este pequeña fuente de energía limpia. Turbina funcionando en Guatemala. New device generates electricity from condensation. MIT researchers have found a way to generate small amounts of electricity from condensation, by having electrically-charged droplets jump between superhydrophobic (water-repelling) and hydrophilic (water-attracting) metal plates.

The advance could be especially useful in remote areas or developing countries, not least because it produces clean water as a side product. While pulling electricity out of thin air is a physical impossibility, producing it from water droplets in the atmosphere is very much within our reach. HEB Home. BioPower Systems. The microhydro plant. My little paradise has a stream that provides enough water flow and head to run a small turbine, to provide electricity to my home.

The microhydro plant

While writing this, the microhydro plant is being implemented, and here are some photos of the process. Since I usually like to start at the end, the first thing I built is the controller: It is an implementation of Jan Portegijs' "Humming Bird", with some changes and adaptations. The largest cost of the plant, by far, is in the piping for the rather long penstock.

When the purchase was made and the truck arrived, we unloaded the pipes at different places, to get them as close to the installation area as possible. Shower of the Future. Pump Water Without Electricity - energy of flowing water. (Before It's News) A water wheel uses the energy of flowing water to move the water through coiled pipe and as it spins it continues adding water through the coils.

Pump Water Without Electricity - energy of flowing water

Depending upon where you set the output pipes you can move water from a creek to your field without electricity.
