Storing Energy

Posted by in category: energy

What is ideally needed is a bulk electricity storage device which is scalable to gig watt, which is reliable, efficient and economically viable, but more importantly, it should be environmentally friendly. One such promising technology on the horizon with a capability to compete with pumped hydro and gas turbines for peaking and immediate power generation is storing energy by gravity.

A gravity storage system consist of a pair of two deep shafts one large, and the other smaller in diameter connected at the top and bottom, forming a closed formed circuit via a reversible pumpturbine, as seen in Figure 1. The shafts are filled with water, which acts as a medium for energy transfer, and the bigger shaft is fitted with a huge steel piston filled with reinforced rock and concrete. The whole device operates on the simple action of vertical motion of piston.

UN panel warns against ‘designer babies’ and eugenics in ‘editing’ of human DNA

Posted by in categories: biotech/medical, ethics, genetics

Warning that rapid advances in genetics make “designer babies” an increasing possibility, a United Nations panel today called for a moratorium on “editing” the human genome, pending wider public debate lest changes in DNA be transmitted to future generations or foster eugenics.

While acknowledging the therapeutic value of genetic interventions, the panel stressed that the process raises serious concerns, especially if the editing of the human genome should be applied to the germline, thereby introducing hereditary modifications.

“Gene therapy could be a watershed in the history of medicine and genome editing is unquestionably one of the most promising undertakings of science for the sake of all humankind,” the UN Educational, Scientific and Cultural Organization (UNESCO) said in a news release on a report by its International Bioethics Committee (IBC).

Australian engineers just built a quantum logic gate in silicon for the first time

Posted by in categories: computing, materials, particle physics, quantum physics

For decades, researchers have been trying to build a computer that harnesses the enormous potential of quantum mechanics. Now engineers from the University of New South Wales (UNSW) in Australia have overcome the final hurdle, by creating a quantum logic gate in silicon — the same material that today’s computer chips are made from.

The newly developed device allows two quantum bits — or qubits — to communicate and perform calculations together, which is a crucial requirement for quantum computers. Even better, the researchers have also worked out how to scale the technology up to millions of qubits, which means they now have the ability to build the world’s first quantum processor chip and, eventually, the first silicon-based quantum computer.

This Startup Wants To Plant One Billion Trees a Year Using Drones

Posted by in categories: drones, engineering, food, information science, robotics/AI

The future of Eco conservation?


Deforestation downs 10 billion trees around the globe annually. Replanting trees by hand is slow, expensive, and barely puts a dent in reversing the damage. But one startup wants to use drones that can reforest our increasingly tree-strapped Earth, on a big enough scale to replace slow and expensive hired humans.

The small company, called BioCarbon Engineering, says unmanned aerial vehicles are a great way of covering ravaged woodlands with seedlings that can repopulate the area’s tree population. Around the world, forests and jungles are still being leveled due to lumber overproduction, strip surface mining, urban expansion, and land use for agriculture.

A quantum logic gate in silicon built for the for the first time (w/video)

Posted by in categories: computing, encryption, quantum physics, supercomputing

A Game Changer in Quantum Computing:
The ingredients for superfast computers could be nearly in place. For the first time, researchers have demonstrated that two silicon transistors acting as quantum bits can perform a tiny calculation.

The advance represents the final physical component needed to realise the promise of super-powerful silicon quantum computers, which harness the science of the very small — the strange behaviour of subatomic particles — to solve computing challenges that are beyond the reach of even today’s fastest supercomputers. Potentially transforming fields like encryption and the search for new pharmaceuticals.

Ray Kurzweil on Artificial Intelligence: Don’t Listen to Stephen Hawking and Elon Musk

Posted by in categories: Elon Musk, Ray Kurzweil, robotics/AI

There’s a rift emerging among the members of the tech super-geniuses club. It’s not about matters of human intelligence, though. Physicist Stephen Hawking and Tesla /SpaceX founder Elon Musk have both recently warned that our sci-fi nightmares about artificial intelligence could actually come true in our lifetimes.

Here’s what Musk, for instance, said during a recent stop at MIT:

I think we should be very careful about artificial intelligence. Our biggest existential threat is probably that … There should be some regulatory oversight at the national and international level, just to make sure that we don’t do something very foolish. With artificial intelligence we are summoning the demon. In all those stories where there’s the guy with the pentagram and the holy water, it’s like, he’s sure he can control the demon. Didn’t work out.
