Here is some information about optimal wind turbine power generation. Wind Turbines are limited by what is called the Betz law. Simply put, if you capture 100% of the energy available in the wind, you stop the wind. The Betz limit says that essentially, if you capture 59.6% of the energy in the wind, that …
Electricity generated from waves and motion by using low friction ferrofluid. Ferrofluid over a magnet is 40 times slippier than ice. Jeffrey Cheung of Rockwell Scientific in Los Angeles has generated at least 0.3 watts from a ocean buoy even in very calm waters. One hope is that in three years this could be scaled …
If confirmed, a gravitomagnetic field of measurable magnitude (one thousands of the earths gravity) was produced for the first time in a laboratory environment. These results may open up a new experimental window on testing general relativity and its consequences using coherent matter. The field was generated by a rapidly spinning superconducting disc.The full paper …
A functioning processor on a carbon nanotube has been created by IBM scientists, offering the possibility of terahertz processors in hybrid nanotube silicon devices in 5-10 years. The IBM researchers created a type of logic device called a ring oscillator. It consisted of 12 bi-metal field effect transistors laid along the 18 micrometre length of …
Widescale monitoring that is in the works now.China is looking to use RFIDs to track 13 billion chickens. Recent RFID pricing is 7.2 cents per tag in orders of 10 million China is issuing RFID identity cards. This site has discussed RFID technology before Even without molecular nanotechnology…by applying moore’s law to RFIDs. In 20 …
Author and Pentagon advisor John Arquilla believes that today’s big-weapon systems are wrong for modern battle and for future battle Some of the main points: how many British submarines did it take to pen up the entire Argentine navy? Two. The Exocet missile proved the slow-moving capital ship’s vulnerability. Today, the Chinese aren’t developing aircraft …
Samsung has introduced a 32-gigabyte (GB) NAND flash-based solid state disk (SSD) for about $500. Last year (2005) a 16-gigabyte drive cost $900. This drive reads 3 times faster than a regular magnetic hard drive and writes 1.5 times faster. Samsung project SSD will account for 30% of the global laptop market as the price …
Improvements in the cost and performance of LCDs and plasma televisions is reducing interest in carbon nanotube televisions Work is still being done, but improvements in other technology is making it difficult for the new technology to impact the market. Brian WangBrian Wang is a Futurist Thought Leader and a popular Science blogger with 1 …
Gene Therapy goal: deliver desired genes to cells to either cure disease or improve body functions such as stronger muscles. Gene therapy has the potential to enhance human performance and cure diseases. Problem: Viruses used for gene delivery occasionally cause severe immune responses. The novel lipid molecule created at UC Santa Barbara has a tree-shaped, …
This is progress achieved via advanced chemistry towards more complex molecular machinery. A pair of light activated molecular pliers has been joined to a pair molecular flippersThe result is the first example of one molecular machine controllably driving the action of another, say the researchers. “The next step is to integrate multiple molecular machines” into …
Here is a summary of recent advances in regards to robotics. Some have been mentioned before on this blog, but are summarized here. New consumer robots. Furry robot horse that can be ridden $300 Robotic pack mule, 4 legs, stable, able to carry over 40 kilograms 100 times more powerful artificial robot muscle Currently, robotic …
