Overheard medical marijuana growers discussing high electric bills and that their air conditioners run even when it is freezing outside. They do enriched CO2 growing which boosts yields but precludes exchanging air with the outdoors.

The obvious solution was to switch to LED grow lights. But that still dumps a lot of heat into the grow space. Unlike the traditional grow lights (HPS) which emit heat radiant in all directions, LEDs emit most of their heat off of the back side via conduction and with COB LEDs this heat is emitted in a concentrated area. Capturing this heat while it is still concentrated and getting it out of the grow space would drastically reduce AC infrastructure requirements and electricity ...

The Hyper4 (a 4 stroke, 4 cylinder engine) improves the fuel efficiency of internal combustion engines by up to 75% (as reflected by Simulink Matlab and Converge CFD modelling software), approaching 50% brake thermal efficiency in a unique, compact axial design that is both straightforward and inexpensive to manufacture. Unlike a standard inline engine, the incorporation of Constant Volume Combustion, Variable Compression ratios and Over expansion is virtually effortless. These fuel saving strategies are well known, researched and documented but are extremely difficult to implement in a crankshaft controlled engine. The configuration allows for the inclusion of rotary valves and water injection for internal cooling and the reduction of NOx emissions.

The cam tracks provide for the different piston ...

This innovation relates to the modification of the surface of solar panels to increase the efficiency. In essence, this technology will make use of flexible solar cells that can be made to conform to other than a planar surface. In this way, even if no optimal orientation at 90 degrees from the solar radiation angle, still higher efficiency can be obtained. This concept shares some similarities with a technique used in materials characterization called x-ray diffraction. In this technique, a powdered material is subjected to x-ray radiation and as the x-rays diffract they permit the identification of phases due to the orientation of crystals in the material. The randomized nature of the crystals in the powdered material give rise ...

The advancement of analytical water characterization methods has revealed the presence of a new class of water contaminations known as emerging contaminants. One of the main groups of this class of contaminants is pharmaceutical compounds, including the medicines used by individuals everyday. These contaminants have a widespread presence in the effluent of wastewater treatment plants and hospitals with proven negative impacts on aquatic species. The inefficiency of current standard treatment strategies in elimination of pharmaceutical compounds has initiated efforts to create innovative and more effective treatment technologies.

At Roshan Water Solutions, we have developed a new water treatment technology inspired by the inherent cleansing power of lightning bolts. This technology, PlasmaClens(TM), uses helical resonators to enable the creation of ...

Our concept lies within the realm of green energy and by our intent we seek a better world where we wouldn’t have to compromise the integrity of our little place in this solar system.

We seek to merge Nano-crystalline solar cells (thin film) with wind turbines, so that we can obtain more energy from a single structure. The rotor blades of the wind turbines are coated with Nano crystal solar cells and the tower is covered with curved solar panels. When photovoltaic cells overheat, they become less efficient. The constant spinning of the rotor blades cools the cells.

The unoccupied space in the tower of the wind turbines can be covered by curved solar panels. Even in non-monsoon seasons, ...

The laws of physics restrict the rotational speeds of traditional large generators due to the increased centrifugal forces. Hoover Dam generators run at around 1.5 - 2.0 Hz.; their substantial centrifugal forces require these and similar generators to run at relatively low frequencies which results in very low specific outputs (kW/lb. and kW/ft3).

DET has patented a generator that is based on Faraday's Law, NASA developed ultra-high speed flywheel technology and Formula 1 engine principles. The result is a compact, high speed generator that has the potential to operate at up to 1,000 Hz. and produce extremely high specific power outputs. Faraday's Law, that both voltage and current increase proportional to the increase in the oscillation frequency, predicts that ...

The most common contaminants of water are organic compounds, bacteria and protozoa that pose a great risk to human health. However, the existence of recalcitrant pollutants prevents effective treatment by conventional methods. A novel environmentally friendly alternative for the elimination of recalcitrant pollutants is the advanced oxidation processes, such as photocatalysis (TiO2).

LimpiAgua is a device that is used to treat water, based on TiO2 photocatalysis. This device is very useful in developing countries where many people do not have access to drinking water and therefore children and the elderly tend to be constantly sick and in rural areas. Treating the waters Residual and the reuse power that makes cleaners contribute to a more sustainable world and have a ...

Liter of Light is a global open source movement that aims to provide ecologically-sustainable lighting solutions using photovoltaic technology and simple materials for those who don’t have adequate access to electricity or who cannot afford it.

In 2015, Liter of Light won the Zayed Energy Prize, the Nobel Prize for the Environment and UN’s World Habitat Awards.

In Brazil, Liter of Light is named as Litro de Luz Brasil and was created in 2014. Litro de Luz Brasil innovates from a social perspective, since all the technology and knowledge is taught to the communities, so they can use basic electronics skills to replicate the technology, independently from Litro de Luz Brasil’s support. We train low income citizens to build ...

Providing clean water in humanitarian emergencies is essential, however few household water purification systems have been developed with this context in mind. In an emergency setting usability, durability, transportability, and cost arise as crucial aspects of purification systems design that sit alongside the vital pathogen filtering capacity of the technologies. Focusing on these features of purification systems, in addition to their filtering capabilities,is essential to improve water treatment in humanitarian emergencies.

THE METHODS:
In this study, flood water collected in a bucket (20 L) from nearby sources and 2.0 gram of MOSP (moringa seed powder, and shell powder) were added and mixed vigorously and left for 10 minutes showed a clear water layer at the top and a sediment layer at ...

Andean indigenous people are settling in highland and low temperate valleys in which they are farmers using very ancient technology to optimize the land and water resources. About two million Aymara live in Bolivia, five hundred thousand in Peru, and one hundred thousand in Chile They built an agriculture systems with terracing, canals and irrigation works, with a sustainable production of organic foods. This landscape was completely modified by the modern society, introducing monoculture and chemicals, transforming agriculture without any consideration to environmental and social impact. Today, most of the people living in these valleys has a very low income and land and water present a high pollution, with severe degradation of the environment. Causes are anthropogenic and natural ...
