In the year 2015, the hot weather in India caused lots of people to die.

I designed a house with a special structure which can make it cooler in the house than outside. The house is made by a special structure which has special thermal property. The roof and the wall of the house is made of a honeycomb structure. However, on the basis of the honeycomb, we add some new structural design for making the air in the structure flow in an special way and the neighboring cell of the honecomb is made of different material with different thermal property. The flow in the structure could takes the heat in the structure outside and the heat ...

The wind is a renewable energy source. Wind turbines can convert its kinetic energy into electricity. As the windiest country in Europe, the UK is well placed to harness wind energy. A wind turbine is a device that converts kinetic energy from the wind into electrical power. A wind turbine used for charging batteries may be referred to as a wind charger.

Not all the energy of blowing wind can be harvested, since conservation of mass requires that as much mass of air exits the turbine as enters it. Betz' law gives the maximal achievable extraction of wind power by a wind turbine as 59% of the total kinetic energy of the air flowing through the turbine.Further inefficiencies, ...

Addressable light fixture controller is a simple and small electronic device designed to be used in a single switch with multiple light fixtures configuration in a room. This configuration is often found in large kitchen, living room, family room, and master bed room in an average house. This configuration is also found in office, conference room, class room, etc.

This addressable light fixture conroller can be installed to each light fixture to be address controlled by the single switch. Each light fixture can be turned on according to it's address by quickly toggling the switch.

Refer to Figure 1, a room with such single switch multiple light fixtures configuration can be instantly reconfigured with this device without rerunning the ...

Egypt is experiencing one of its most serious energy crises for decades, with parts of the country facing around six power cuts a day for up to two hours at a time. The blackouts have created widespread frustration, with businesses reporting a downturn in production and citizens complaining about the disruption to everyday life. Egypt experiences frequent electricity blackouts because of rising demand, natural gas supply shortages, aging infrastructure, and inadequate generation and transmission capacity.

From this view we started to think in our project idea of using the solar energy instead of electrical energy and depends mainly in Air Conditioners and refrigerators and this will has two benefits:

1. Reduce the gap in electrical power stations in Egypt

A simple, flexible, innovative design to capture wind energy at a fraction of the price, the AirLoom has the potential to disrupt the entire (not just renewable) electricity generation market.

The AirLoom dramatically reduces the capital cost of wind turbines by an astounding 15X over the dominant wind technology, the horizontal axis wind turbine (HAWT). It captures large swept areas of wind at low cost by placing multiple airfoils on a vertical oval track, with all forces distributed and supported by tension cables. The AirLoom’s patented design represents a 23X reduction in the HAWT’s mass, resulting in a dramatic reduction in manufacturing, transportation, maintenance and land costs.

Although the AirLoom doesn’t look much like a HAWT, it uses the ...

Air conditioning is one of the energy hogs around. If you live in Texas, you spend an extra 150$ a month in the summer months, for a 2500. sq ft. home, on cooling.

This project is a way to reduce or eliminate that bill. Every kilometer you go up in air, temperature drops 6 ºC in the Troposphere, the lowest layer of atmosphere extending to 12Km.

The solar powered baloon keeps the tubes and pumps floating in the air. It is tethered to the roof top or ground.

The inlet air is filtered and pumped into the house by an air pump in the house through a kilometer high plastic tube. This is a low energy pump as colder ...

The idea is basically to get some energy from passing autos as an indemnification for to increase inner city's air quality and also produce electricity to use for inner city's benefit. This is an example of the process of an energy recycling system designed for Blaubach and Tel-Aviv street's junction in Cologne.

This system is based on the gain of energy which is retrieved from the weight of passing objects. While the objects pass, there is a system which will transform the weight energy of the object into pneumatic energy through the use of designed pumps. by stocking the air in air tanks up to a particular high pressure by transforming the pneumatic energy into electricity. Direct that energy ...

Autogro is a lowcost single plant hydroponic system. Each module is self contained and is able to monitor nutrient and light conditions and adjust for each individual plant. Each plant can be monitored remotely and permits remote manipulation of the plants environment and long-term monitoring of individual ...

In India most of the vehicles are parked in an open environment that is exposed to sunlight directly and temperature outside can go beyond 40 degree Celsius in summer. Due to this effect the inside temperature of a parked vehicle may go up to 120 degree Celsius due to convection, conduction and radiation. To minimize the inside temperature and to avoid thermal stresses without using the engine power, solar energy can be used to provide power to the ventilation system which removes the additional heat inside the cabin by inducing fresh air using rotors and fans.

The solar panel in this case does not consume much space as it used some thin sheet like materials which can be pasted ...

I’ve designed WiWater. WiWater is a battery-free wireless system of localized measuring of water consumption. So, this is a system capable of measuring how much water we consume while we are taking a shower, brushing our teeth, watering the garden, washing our clothes or the dishes, etc.

Users will see the consumed amount in their smartphones or tablets, just accessing a web address (The address of the WiWater small web server).

Due to the fact that every sensor distributed all over the house is wireless and battery-free, the installation is simple and maintenance is not required: It is the ideal system!

The access point is the only thing that should be connected to the power supply. The access point ...
