Geothermal heat from a depth of 4,000 metres to generate power in the future
Why roam far afield, when the good is so close at hand? Humankind burns coal, gas and oil to generate energy. It splits atoms, converts sunlight into electricity and tries to capture the wind. Yet, the earth beneath our feet contains energy enough to satisfy even the greatest demand, because 99% of the Earth is hotter that 1000°C, while 99% of the rest is actually hotter than 100°C. Only the Earth’s surface is comparatively cool. The deeper one goes, the warmer it becomes: on average by 3° Celsius per 100 metres. But how can this geothermal heat be brought to the surface? How can it be used to generate electricity? Scientists at the GeoForschungsZentrum Potsdam are studying questions like these.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
