Graphite transistors could be the replacement for silicon

Graphene is one hundred times thinner than the smallest silicon transistor possible and graphene conducts electricity much more efficiently. However, graphene sheets tend to curl up and react with substances around them, making them difficult to build into devices. Graphite could provide the most of the electrical property benefits of graphene but be easier to …

Energy efficiency and substitution

A biofuel announcement and updating my energy forecast and recommended energy policy. General Motors announced a partnership with Coskata of Warrenville, IL, a new company that claims it can make ethanol from wood chips, grass, and trash–including old tires–for a dollar a gallon. Coskata is completing a pilot-scale ethanol production facility and will announce locations …

3d waveguide is promising for optical computers

Researchers have created a new process for making complex miniature waveguides that can steer optical signals in three dimensions through solid materials. All optical computers could approach the theoretical speed of a photonic switch which is estimated to be on the order of petahertz (10**15). They should definitely achieve multi-terahertz speeds. So 1000 to 1 …

Nanotechnology enhanced steel and concrete for safer skyscrapers

New materials are making the new generation of skyscrapers safer. The problem for the World Trade Center was that regular steel: Above 750 F, steel starts to lose its structural integrity, and at 1100 F, steel loses 50 percent of its strength. A new formula infuses steel with nanoscale copper particles, this formula could maintain …

Yeast life span extended to equivalent of 800 yeast years

Biologists have created baker’s yeast capable of living to 800 in yeast years without apparent side effects. The basic but important discovery, achieved through a combination of dietary and genetic changes, brings science closer to controlling the survival and health of the unit of all living systems: the cell. The study is scheduled to appear …

Cheaper thermoelectric from silicon nanowires

Rough silicon nanowires synthesized by Berkeley National Lab researchers demonstrated high performance thermoelectric properties even at room temperature when connected between two suspended heating pads. Nearly all of the world’s electrical power, approximately 10 trillion Watts, is generated by heat engines, giant gas or steam-powered turbines that convert heat to mechanical energy, which is then …

Stealth submarines invisible to sonar with metamaterial design

Duke University engineers will reveal Friday (Jan. 11) details of an acoustic cloak fabricated from metamaterials that they claim can render objects invisible to sonar. If this works then we will have unprecedented control to hide from the effects or to enhance the effects of sound and other waves in all kinds of material. Submarines …
