toward a low energy computer: efficient caches

mon, 26 dec 2011 08:00:22 +0000

in an nsf-sponsored project, computer scientists at the university of utah have developed techniques to reduce the energy consumption of computers associated with large, temporary storage areas, called caches.

the innovation could significantly lower energy consumption and improve performance within multi-core processors, directly impacting future computing devices including laptops, desktops and server processors.

the group explored the use of algorithms to reduce on-chip communication time, while also exploring ways to change wiring patterns for improved energy efficiency.

in the near future, processors will incorporate tens to hundreds of cores and large caches as well as complex on-chip networks to connect these systems. in such architectures, during tasks and necessary checks for operation, a large fraction of processor delay and power use will occur within the on-chip network.

by combining algorithms and a wiring technique known as low-swing wires, professor rajeev balasubramonian’s group showed that limited use of low-swing wires can yield compelling improvements in terms of performance and power.

replace home windows with eco-safe top slider windows

mon, 31 jan 2011 09:45:54 +0000

the eco-safe top slider window safely allows air to circulate indoors. this window can be safely left open during the daytime and cool nighttime hours, totally cutting down the use of air conditioning in the warm spring, autumn, and summer months. the slightly veriable top slider opening measures approximatly 15″x19″, making it too small for intruder entry. heat rises, and the top slider window uses this constant to allow the heat to escape and cool off any interior space bounded by top slider windows. i live in southern california and i can maintain my electric bill at $10-$13 per month. only when it remains in the 90’s for several days do i have to make use of air conditioning.
i designed then special-ordered this design through milgard windows and having lived in new york city for many years, i know that this design would be very suitable and safe for the high-rise living there.

greensulate: rigid board insulation made out of mushrooms instead of petrochemicals

wed, 10 nov 2010 11:28:21 +0000

editor’s note: tune in on monday to our segment on bloomberg west to hear the latest exciting news from ecovative!

mushroom materials can be used for a variety of building applications, including insulation, structural insulating panels and acoustical tiles. these materials have low or no vocs (volatile organic compounds), are fire resistant, and perform similarly to traditional synthetic materials.

ecovative insulation helps you reduce the amount of energy used to build your home, and is a safer material for your well-insulated building. there are many great loose fill or batt insulations that are eco-friendly, but almost all rigid board insulation is made from petrochemicals, resulting in significant co2 emissions during the manufacturing process. proper construction with rigid board insulation provides a tighter envelope with fewer thermal bridges resulting in a more energy efficient building.

mushroom insulation is safe to touch and can be installed without any special safety gear. additionally there are no spores or allergy concerns associated with the use of this material, and it achieves a class 1 fire rating without needing toxic fire retardants.
