Wind up battery wants to save the world. As humans, we've begun to realise just how much our actions affect the planet and its creatures, each of which is precious and has its own place in the global scheme of things. The answers as to how to ensure that we don't make more animals or even ourselves extinct are complex, but one thing is for certain, we need to live in a sustainable way.

Is a Hydrogen Boat or Ship the Future of Sea and River Transport?

A short while ago we  discussed how hydrogen fuel cell cars would affect the future. Today, I'd like to write about another form of transport that is looking for alternative fuel sources.

Solar Powered Refrigerator Technology cools Africa and Domestic locations too

A completely stand-alone refrigerator powered by solar energy has been developed  by the High School of engineering and management of the canton of Vaud and the Albert Schweizer ecological Center in Neuchâtel.  

This solar refrigerator is meant for use in sub-Saharan Africa.

Is geothermal electricity the answer to constant renewable energy?

Prame Chopra, former professor of geophysics in the National Australian University, thinks that the energy of “hot dry rocks”, known as geothermal energy, is the answer to humanity's future power requirements.

CETO Wave Energy aims to produce 50% of Mauritius' Power Requirements

Imagine buoys seven metres in diameter submerged three metres below the sea's surface. The wave motion against these buoys operates turbines which pump the water at very high pressure through a pipeline to a generatore on the shore.  Once ashore the pressurisied water powers the generator to produce electricity. That's how the CETO Wave Energy Technology system works. This revolutionary new technique has been developed by the Australian Carnegie Corporation.

The Future of Fuel Cells and the Hydrogen Powered Car

In less than 20 years from now, driven by the oil crisis and global warming, hydrogen could become an almost regular energy source in our daily lives, potentially being used to power anything from mobile phones to heating buildings and all the way through to our daily transport.

Practicalities and Cost of Solar Heating

Size Requirements

Hot water production installations are sized according to the number of people in the household. Surfaces of 1.5 m² per person of flat collector, or 1 m ² per person of vacuum tube collector can be considered to be indicative requirements. The tank should have a capacity about 80 litres per person.

Solar Heating Panels and other Components of a Solar Hot Water System

Solar heating components 

Flat collector

The frequently used flat collector panels include a housing isolated with a transparent covering of the solar radiation absorber. The absorber is generally a sheeting of dark copper, with a special coating, which absorbs heat and transmits it to a heat transfer fluid. The heated fluid is transported towards the tank by pipes.

Solar Heating Information: Installation of a Heat System for Homes.

As part of Wind Up Battery’s push to get everyone thinking about renewable energy, we present, just in time for the summer, a real summer theme: solar energy.  Here, it is not a question of photovoltaic cells which convert solar energy into electricity, but of thermal solar installations, that is to say the production of heat using solar heat collectors.  Unlike photovoltaic systems where extremely complex physical processes transform the sunlight into electric current, solar heating is within the reach of everyone:  the solar radiation which hits the collector is transformed

Organic Photovoltaic Cells Gaining on Traditional Solar Technology

If inorganic semiconductors are currently top of the heap in pholtovoltaic technology, organic molecules with identical properties are starting to appear, which could knock the inorganic semiconductors off of the top of that green energy production heap.

Is a Bamboo Computer the Future of Electronics?

Is a bamboo computer a sign of the future of electronics and personal devices, or just the fancy of extremist environmentalists? Could it even be an April Fool's joke? Some computer makers are starting to think that natural products really can compliment the technological wizardry of our times.
