Aussie Student Supercharges ADSL Connections
Australian researcher develops tech to raise internet speed x100, which should hit the market in 2 to 3 years.
Quotes :
Dr. Papandriopoulos's PhD thesis is comprised with methods and techniques to use mathematic algorithms to reduce interference in DSL lines. This research is grabbing international attention due to the promise it holds; ADSL connections implementing the algorithm can go from approximately 1-10 Mbps to a blazing 100 Mbps or above.
Dr. Papandriopoulos's technology revolves around the interference and cross-talk that occurs between the cable wires of high-speed ADSL (Asymmetric DSL) wires. This significant cross talk and the resulting interference forces providers to settle for lower speeds.
"That is not an issue for voice calls these days but it becomes a problem when you're trying to wring more bandwidth out of these existing copper telephone wires [which power ADSL broadband connections],â€

This is the smallest unit of measurement theoretically possible in nature.
With this, we can now probe the nature of space and gravity itself.

Ultra-strong Nanotube Fibers Now Possible
Remember how nanotubes were touted for making a space elevator, because they're potentially 100x stronger than steel, etc?
Of course, little flaws and difficulties have prevented that dream from coming true -- thusfar. But now, those difficulties are being overcome, and the idealized physical strength of nanotubes is starting to be actualized.

New Material Promises to Save LCD, Solar Power Industry
German researchers claim breakthrough that may salvage the solar industry from the brink of disaster.
Quote :
Solar cells have always relied on the metal indium, due to its transparency, which is essential to light emission or absorption in electronics. Engineers also regard indium valuable in LCDs and other transparent electrical devices. However, indium is a relatively rare metal on Earth and existing supplies are rapidly dwindling. Researchers have frantically searched for transparent conducting materials to little avail.
A new team claims it may have found the solution in one of the Earth's most abundant elements. Researchers at the Planck Institute have devised a new approach, utilizing graphene -- single 2D layers of carbon atoms, extracted from graphite -- 10 layers of which are applied to form an electrode. Each layer that comprises the electrode is a mere 5 nm thick.
The material has conductivity comparable or superior to indium and falls just slightly short of indium in transparent character. The current device is 80% transparent to visible light and 100% transparent to infrared light.

Cheap, Efficient Solar - Even at Night!
A new solar technology based on tiny nano-sized antennae is capable of harvesting energy with 80% efficiency, as opposed to the 10-20% seen on commercial solar panels today. But if that isn't amazing enough for you, these new panels can even harvest energy at night, by absorbing light from the infrared region of the spectrum, which continues to residually radiate during nighttime. And even better still is that solar panels based on this technology could be manufactured even more cheaply than existing silicon-based solar panels today. Now these are innovations that Indians need to pay attention to, as they could liberate countless masses from misery, providing power 24/7.

This article's nearly a year old, and yet it contains a relatively recent piece of progress, which I've only just noticed:

The excitation state of the metastable nuclear isomer of Thorium-229 relative to ground has been accurately measured. If further research can trigger its transition back to ground, then this could lead to the nuclear battery.
Nuclear isomers have the potential to store and release vast quantities of energy without actually splitting the atomic nucleus. As such, they are capable of powering everything from advanced aerospace vehicles to potent new WMD not covered by by the NPT.
I personally even think that India should try to fund joint research in this area with Russia. This technology could fundamentally transform the world.

Another interesting new development:

An aluminum alloy has been developed which, on contact with water, will split that water into hydrogen and oxygen. In this way, hydrogen can immediately be created on demand from water, and used to power a combustion engine or fuel cell, with the exhaust product again being water.
Is this some kind of perpetual free energy system? No, of course not -- when the aluminum alloy reduces the water to free the hydrogen, the oxygen is then bound to surface of the aluminum, thus oxidizing it into alumina (aka. aluminum oxide). Energy (eg. electricity) has to be used to remove that oxygen to refresh the alloy back to its original state.
But the point is that this type of system would allow hydrogen to be produced on demand, from stored water. This could allow hydrogen filling stations to simply store water onhand, rather than the dangerously volatile and combustible hydrogen gas. They could then use aluminum alloy in conjunction with electricity to produce hydrogen to fill up hydrogen-powered vehicles on demand.

Specialized nanotubes set the record for the blackest material on Earth
Chalk up another valuable use of carbon nanotubes -- creating the darkest material on Earth. Last month researchers at Rice College and Rensselaer Polytechnic Institute in New York used the handy carbon molecular structures to set an unusual world record -- the record for the most light-absorbing material known to man.
To give an idea of exactly how black the result is, black paint reflects approximately 5 percent of the visible light that strikes it. The previous darkest material was a nickel-phosphorous compound, which only reflected 0.35 percent of visible light. The new nanotube compound blows away these previous competitors, reflecting a bare 0.045 percent of the visible light that hits it. This is almost nine times less than the previous record holder and over a hundred times less than black paint.
http://www.dailytech.com/Military+Goes+ ... e10813.htmThe first possible business application considered by Rice and RPI was solar power. Despite the recognition, though, the solar industry remains relatively lukewarm to the new material. While a few companies such as SolFocus contacted the team, others like Marc Cortez, executive vice president of sales and marketing at Soliant Energy were skeptical about the technology. Mr. Cortez stated doubts about whether the technology could make an impact, stating, "The ultimate challenge will be to take it from the lab into a high-volume manufacturing environment. It’s only then you’ll know whether or not it will be a 'game-changing' technology."
With the solar power industry not warming up enough to the new technology, a new group has jumped in to court Rice and RPI -- the U.S. Military. The Military, according to Popular Science, approached the researchers with interest in using the technology. The Military, which is investigating a number of nanotube applications, expressed hopes for employing the technology to make its B-2 stealth bombers even stealthier. By using the material, the B-2s would be capable of absorbing even more radar, making them more difficult to spot. The military is excited about how the new material could revolutionize its stealth efforts, making its arsenal deadlier and more efficient than ever.
Meanwhile, Professor Yu-Lin is quick to remind people of the technology's more peaceful applications such as improving the efficiency of solar panels, which are typically coated in more reflective black paint. Another valuable application, he believes is using the material to line telescope barrels to provide a darker background to provide less interference with the focused celestial light.
Yeah, I read that -- it was synthesized by a team which included Dr Pulickel Ajayan from Rice University in Texas (he's formerly from Rensselaer).
It would likely be useful for stealth, where every bit of absorption counts, but for solar power it would hardly absorb much more energy than existing black paints.
