- IBM: Commercial Nanotube Transistors Are Coming Soon
Chips made with nanotube transistors, which could be five times faster, should be ready around 2020, says IBM.
For more than a decade, engineers have been fretting that they are running out of tricks for continuing to shrink silicon transistors. Intel’s latest chips have transistors with features as small as 14 nanometers, but it is unclear how the industry can keep scaling down silicon transistors much further or what might replace them.
- Two-Bladed Wind Turbines Make a Comeback
Wind-turbine designers are warming up to an alternative to the three-bladed rotors that have been an industry standard for the past quarter century.
Several major wind-power companies are testing a departure from the industry’s standard three-bladed turbine design by dropping one of the three blades and spinning the rotor 180 degrees to face downwind.
