Ateenager has invented and developed a phone charger which uses energy from the human body to get the energy to charge your phone.

HandEnergy, the brainchild of 19-year-old inventor Michael Vaga, allows you to charge your phone simply by rotating your hand, which activates the device’s gyroscope to produce energy that can then either be stored or used to immediately charge a mobile.

Teenager invents phone charger which generates energy from the human body

The device would be ideal for someone spending a long time away from a power so

The kickstarter, which hoped to raise €50,000, raised €71,333 from people hoping to get their hands on one.

Now, the inventor from Minsk, Belarus, is ready to make and send out the innovative portable chargers.

He said: "With each rotation of your hand, the rotor speed increases significantly and generates more power. The average speed of the rotor is 5,000rpm. 

"We translate the mechanical energy you put in into electrical energy and this means you can charge your device."

The invention took over a year to develop, and Mr Vaga has said it is ideal for people who spend a long time away from a power source.

It takes between 40 minutes and one hour to fully charge the batteries of the HandEnergy device.

This speed is reduced by 30 per cent if a phone is being charged at the same time.

Mr Vaga said the charger is good as an emergency source of energy, but also it is an example of clean energy.

HandEnergy will be available from March 2017 with an expected retail price of €99 (£84). 

New Solar Panels Can Generate Power From Rain

New Solar Panels Can Generate Power From Rain   Science & Technology World Website


Whilst we may not have a lot of sun here in the UK there is one thing that we do get and that is rain and now some new solar panels have been developed that also generate power from rain as well as sun.

The new solar panels were developed by scientists from China and they feature a layer of graphene that can generate energy from rain drops.

The solar panels harvest energy from rain as the water sticks to the graphene, it then creates a natural capacitor and then generates electricity, the panels also generate energy from sunlight like normal solar panels, this would be an ideal solution for places like the UK which get a lot more rain than sun.

Solar panels generate around 22 percent energy, unfortunately these new panels only convert to around 6.5 percent energy, if they are able to make them more efficient then they could be a viablle alternative to standard solar panels.

This 'Plant Lamp' uses bacteria to generate electricity

Maintaining infrastructure in the rainforest is a pretty tall order -- the area is dense with vegetation and prone to intense moisture and flooding. Villages like Nuevo Saposoa in Peru have had their electrical grids disabled or destroyed by the elements, leaving residents at the mercy of daylight or the fumes of kerosene lamps to work, read or study. Researchers at Peru's Universidad de Ingeniería y Tecnología have created a novel solution: an LED lamp powered by a houseplant.

UTEC's "plant lamp" is actually more of a conduit for bacteria than an electrified fern -- researchers built a metal grid in a planter that captures energy released from "geobacters," a kind of microrganism that gives off electrons. This grid stores the power into a normal battery which can power the light for up to two hours a day -- providing a brighter, healthier light source than the kerosene lamps Nuevo Saposoa residents have been using since the flood.

Researchers have created 10 fully functional prototypes, which have been distributed to families in the affected village.
