Four mechanical engineering students from Nashik have invented a device which is an indicator for the vehicle driver about excessive pollutant levels, while driving. When the engine of the vehicle starts, the sensor fitted in the silencer will sense the exhaust particles and check the limit value. If it exceeds the prescribed limit then a red light will blink as the first indicator, for two hours. Even after the first warning, if there is no change in the limit then there are two more indicators that will blink within a gap of two hours after which the engine will automatically turn off. According to the four inventors, the device will help in tackling the pollution issue, especially in densely-populated and polluted areas.

A 19-year-old Dutch student had a bright idea for ridding the sea of floating trash -- and now he's built a team of 100 people and is raising $2 million to fund his invention. The system uses long, floating barriers to passively guide floating trash to collection areas and is said to be capable of eliminating all waste larger than 1 millimeter

The new plan will transform an existing site almost entirely covered with buildings and asphalt into a landscape featuring almost 7,000 trees – including the apple, apricot, cherry and plum fruit trees that made San Jose's orchards thrive long before silicon was invented.

2. Renewables
...

Cancel
the campus will run entirely on renewable energy. The plan calls for about 8 megawatts of solar panels to be installed on the roof of the main, spaceship-shaped building as well as the parking structures. An unspecified number of fuel cells also will be installed, with the rest of the electricity needed for operations sourced through grid-purchased renewable energy.
...

Cancel
Primary opposition to the site has centered on its transportation plan. To combat those criticisms, Apple has expanded its Transportation Demand Management program, emphasizing the use of bicycles, shuttles and buses that will link employees with regional public transit networks.

3. Net-zero building design
...

Cancel
the structure itself is being designed to create as much energy as it uses. There is a strong emphasis on energy-efficiency: the passive heating and cooling systems will use 30 percent less than a comparable campus. A central site will contain fuel cells, back-up generators, chillers, condenser water storage, hot water storage, an electrical substation and water and fire pumps.
...

4. Attention to water conservation
...

Cancel
Attention has been paid to reducing the number of impermeable surfaces on the site. (Up to 9,240 of the parking spots, for example, will be underground so that Apple can invest in landscaping that absorbs water. A recycled water main is under consideration, and other steps have been taken to minimize water consumption by about 30 percent below a typical Silicon Valley development. Those measures include low-flow fixtures, the use of native plans and roof rainwater capture.

5. An expanded waste management program
...

Cancel
Apple already diverts about 78 percent of the waste associated with its existing headquarters from landfills. The proposal calls for the company to recycle or reuse any construction waste; from an operations perspective, it will step up recycling from solid waste sources as well as the use of composting.

6. A sharpened focus on commuting alternatives
...

Cancel
As part of its transportation program, the plan calls for buffered bike lanes on streets adjacent to the campus that are segregated from vehicular lanes and that also allow for bikes to pass each other. The focus will be on encouraging all employees that live within 15 minutes of the campus to use sustainable or public transportation alternatives. The site will start with 300 electric vehicle charging stations, with the built-in capacity to expand.

A new product could help people in remote, parched places gain easy access to clean drinking water. The Warka Water, a 30-foot-tall tower shaped like a vase, uses a straw mesh and a nylon net to capture airborne humidity in the form of dew, which it then collects for human use. The device can reportedly gather more than 25 gallons of potable water in a single day, even in desert conditions
