The energy saving contributions of thermal mass are well known but not always implemented in an ideal way.

Total Shade's solar shade is not your typical solar panel system. Unlike traditional solar panels that are mounted on rooftops or in open fields, Total Shade's technology integrates solar energy capture directly into a shade structure.

Lots of people want to have more sustainable homes, not just to help the environment. Because at the end of the day, it's a lot more affordable to get your energy from the sun and the wind than to pay some oil or coal plant to provide it. But for many people, being sustainable means having a home built. Hiring an architect and a contractor and going to all that trouble gets pretty expensive. Thanks to Clayton, sustainable living is about to get much more accessible.[...]

It can be hard to find good advice on how to make homes more energy efficient.

A recent study in Finland suggests new building regulations will lead to a substantial reduction in the total energy demand and CO2 emissions in new apartment buildings. This could have an impact on the source of energy used for new buildings. In particular, the demand for space heating will fall, which could have an impact on the source of energy used for new buildings.

Zero Energy Buildings (ZEBs) are a viable means to reduce global energy demand, a new study suggests. However, in response to the drop in energy costs for the household due to better energy efficiency, people may begin to consume more energy than they otherwise would. These so-called ‘rebound effects’ can undermine emissions reductions, the study says, and it proposes approaches that could lessen these impacts.

Homomorphic encryption (HE) allows direct computations on encrypted data. Despite numerous research efforts, the practicality of HE schemes remains to be demonstrated. In this regard, the enormous size of ciphertexts involved in HE computations degrades computational efficiency. Near-memory Processing (NMP) and Computing-in-memory (CiM) - paradigms where computation is done within the memory boundaries - represent architectural solutions for reducing latency and energy associated with data transfers in data-intensive applications such as HE. This paper introduces CiM-HE, a Computing-in-memory (CiM) architecture that can support operations for the B/FV scheme, a somewhat homomorphic encryption scheme for general computation. CiM-HE hardware consists of customized peripherals such as sense amplifiers, adders, bit-shifters, and sequencing circuits. The peripherals are based on CMOS technology, and could support computations with memory cells of different technologies. Circuit-level simulations are used to evaluate our CiM-HE framework assuming a 6T-SRAM memory. We compare our CiM-HE implementation against (i) two optimized CPU HE implementations, and (ii) an FPGA-based HE accelerator implementation. When compared to a CPU solution, CiM-HE obtains speedups between 4.6x and 9.1x, and energy savings between 266.4x and 532.8x for homomorphic multiplications (the most expensive HE operation). Also, a set of four end-to-end tasks, i.e., mean, variance, linear regression, and inference are up to 1.1x, 7.7x, 7.1x, and 7.5x faster (and 301.1x, 404.6x, 532.3x, and 532.8x more energy efficient). Compared to CPU-based HE in a previous work, CiM-HE obtain 14.3x speed-up and >2600x energy savings. Finally, our design offers 2.2x speed-up with 88.1x energy savings compared to a state-of-the-art FPGA-based accelerator.

The present invention relates to the energy efficient and selective extraction of dilute concentrations of C2-C6 alcohols from an aqueous solution using liquid phase dimethyl ether.

A light directing composite film includes a planar top major surface, a planar bottom major surface, a plurality of lenticular lens elements disposed between the top major surface and the bottom major surface, and a plurality of light reflection regions and light transmission regions disposed between the plurality of lenticular lens and the planar bottom major surface.

A rotary actuator suitable for use in a refrigerator ice-dispensing door provides a rotating shaft driven by a DC permanent magnet motor through a gear train and subject to a returning force of an internal spring. The gear train communicates with a switch to reduce current to the motor when a limit of travel is reached and a shunting path is provided around the motor to produce generative braking when power is removed from the motor and the actuator rotates backward to its initial position.

Energy efficiencies are achieved in a dryer or washer/dryer by selectively varying temperature ranges, time periods, heater power levels, and air flow rates. Efficiency improvements on the order of 16% were obtained over typical constant power, constant temperature, timed drying cycles by varying one or more of these parameters. Efficiencies can also be improved by drawing air from alternative warm sources such as an attic or warm external environment, or by heat recovery from dryer exhaust passages.
