DIY: Generate your own electricity

...energy (itself derived from coal, oil, natural gas, wind, water, nuclear reactions or other sources) into electrical energy. Here, we describe how to use readily available materials to make a simple generator. Although it will only be powerful enough to light a small torch bulb, it works on the same basic principles as the power station generators that supply domestic...

Lifecycle of the Car Industry

...energy on advertising and on price wars, not product innovation. And the fact that advertising is so incredibly expensive, especially in this industry, has reduced tremendously the number of firms – you have a lot of big firms competing on extremely expensive advertising and not on product innovation."

Night sky puts on a meteor shower to celebrate Rosetta’s closest approach to the sun

...solar system. It was last at perihelion (its closest approach to the sun) in 1995. Each time the comet comes to the inner solar system, it sheds dust. Over time, this debris has built up, and is smeared out along the entire track of the orbit. Once a year, in August, the Earth’s orbit crosses that of comet Swift-Tuttle, and dust from the comet is captured. If you record...

...energy generated) created at times of surplus to non-renewable energy generators. So, many so-called 100% green electricity tariffs are a mix of fossil fuel, nuclear and renewables purchased on the wholesale market and then ‘labelled’ green by buying REGO certificates. Other ‘greenwashing’ electricity suppliers, including some who claim to supply 100% renewable...

Reduce e-waste through donating old computer devices

...energy efficient. Moves to do this have started with ‘right to repair’ laws (although they do not cover computers or smartphones yet) and WEEE regulations (waste electrical and electronic equipment) but there are also things we can do now. [A pile of old discard laptop devices on a shop shelf] Reasons to donate Old computers can often have some life left in them. Here...

A new mission to the icy moons of Jupiter

...energy? Do they have a source of water? Do they have sites where water and rock can interact? Are they the right temperature – it can’t be so cold that nothing could survive. And finally, life takes a long time to get started. Has there been enough time for the moon to become habitable? [Photograph of the surface of Europa. The grey-blue icy surface is criss-crossed...

As Cassini reaches the end, we should prepare the next mission

...solar system, or are they frozen ice and mud? Does Titan have a rocky core overlain directly by an icy mantle, or does it have an ocean below the surface? If so, is it made up of water? This all matters because what we have learnt about Titan from Cassini and Huygens has confirmed that it has an active chemistry, based on methane and ammonia. We know that these...
