The technology bringing Sinatra, Tupac back to life

<strong>Hovering holograms!</strong> Take a look at some of the incredible 3D creations made possible by Musion's <strong><a href='http://musion.co.uk/' target='_blank'>Eyeliner</a></strong> projection system.

Musion Eyeliner was famously used to resurrect rapper Tupac in 2012

Frank Sinatra is back, crooning 'Fly Me To The Moon' live in his trademark suit and fedora as if he had never left the stage. A decade and a half after Ol' Blue Eyes passed away, this unexpected new appearance has been made possible with an optical technology called Musion Eyeliner.

Solar lasers, ocean power and volcanoes: unusual energy sources of the future

From volcanoes to wave power and even algae, researchers are looking far and wide for viable energy alternatives to power the planet after oil, gas and coal reserves run out. We take a look through some of the more interesting, promising and downright unusual possible energy sources of the future. <i>Gallery by Matthew Ponsford</i>

Fossil fuels are going to run out. This much we know. No one is entirely certain when they will run out exactly, but we know it will happen eventually.
Some estimates suggest we have about 70 years of coal, gas and oil left; the fossil fuel industry itself insists that we have significantly longer. But everyone agrees they will run out in due course.
So how will the world be powered when we can't rely anymore on fossil fuels? Why with volcanoes, waves, wet wood and solar power from space.
To compensate for the decline of traditional energy sources, researchers around the world are developing innovative new technologies that -- between them -- may provide a long-term solution to our rapidly growing energy needs. Some are familiar, some may seem far-fetched, and some could potentially pose as much of a threat to the environment as fossil fuels themselves....

The coolest things technology has up its sleeve in 2014

<strong>New year, new technology</strong>.<strong> </strong>Take a look through our gallery of the biggest tech stories we're likely to see in 2014.

From wearable technology to space tourism, 2014 will be a year of significant technological leaps. We take a look through some of the most ground-breaking developments of the year ahead.
Electric cars take to the track
As the name suggests, Formula E is all about electric power. The arrival of this new petrol-free motor racing competition is a significant step for both the car and the environment. Two years ago motorsport's international governing body, the Federation Internationale de l'Automobile (FIA), announced its ambitious plan for an electric car race that would mimic the hugely popular F1 series. As the arrival of Formula E looms, experts predict that it could have a big impact on the future of car manufacturing.
Initially, the cars in the competition will be powered by enormous battery engines. Each battery weighs 200 kilograms, producing around 200 kilowatts of power. Depending on the speed, the electric engines will last anywhere from a few hours to just 25 minutes and the cars can reach speeds of up to 220 kilometers per hour.
"If you look in the past, a lot of development in the car industry has come from racing," said Formula E CEO Alejandro Agag. "The transfer of technology is potentially very big."
