Toyota to Plant Flowers at Prius Plants

Toyota has received a lot of criticism over the production process of their Prius because the production process is quite awful for the environment. Toyota has reacted by designing new flowers to absorb bad air from the production facilities.

Toyota has created two flower species that absorb nitrogen oxides and take heat out of the atmosphere.

The flowers, derivatives of the cherry sage plant and the gardenia, were specially developed for the grounds of Toyota’s Prius plant in Toyota City, Japan.

The sage derivative’s leaves have unique characteristics that absorb harmful gases, while the gardenia’s leaves create water vapour in the air, reducing the surface temperature of the factory surrounds and, therefore, reducing the energy needed for cooling, in turn producing less carbon dioxide (CO2).

The two new plants are part of a wide-ranging plan to reduce the impact of Prius manufacture on the environment. Since 1990, the plant has reduced CO2 emissions by 55 per cent.

Brownfields Good for Green Energy

Brownfields are spaces that were used for some industrial production which have left the ground useless for nearly everything – even nature. Gas stations, refineries, and other chemical-intensive buildings tend to ruin the ground beneath their buildings once they close. The fields tend to have too high a concentration of heavy metals or other hazards to humans, plants, and animals.

The Obama administration has proposed that brownfields across the USA be turned into places that house green energy production. Since people don’t like cutting down trees for windmills why not put the windmills where the trees can’t grow?

“In the next decade there’s going to be a lot of renewable energy built, and all that has to go somewhere,” said Jessica Goad, an energy and climate change policy fellow for The Wilderness Society. “We don’t want to see these industrial facilities placed on land that’s pristine. We love the idea of brownfields for renewable energy development because it relieves the (development) pressure on undisturbed places.”

There are many contaminated sites nationwide to choose from.
The Environmental Protection Agency and the National Renewable Energy Laboratory have identified nearly 4,100 contaminated sites deemed economically suitable for wind and solar power development, as well as biomass. Similar maps are expected to be released this month for contaminated sites with geothermal-power potential.

Included in the 4,100 sites are 5 million acres suitable for photovoltaic or concentrated solar power development, and 500,000 acres for wind power. These sites, if fully developed, have the potential to produce 950,000 megawatts – more than the country’s total power needs in 2007, according to EPA data.

Vertical Forests for Cleaner Air

A group of architects are proposing building a skyscraper that would house a small forest to act as an air cleaner near places of pollution production – a vertical forest.

‘It will also cool the air during the hot summer months via the temperature-lowering properties of hundreds of trees.

‘We thought of the CO2 Scraper as a way to place trees in areas where they would ordinarily be difficult or impossible to plant such as near a factory, major road or perhaps even in a densely populated urban area.

‘The idea here was to imagine a structure with relatively small footprint in terms of the amount of ground it covers.’

Scientist and sustainability specialist Joep Meijer, founder of theRightenvironment, has praised the ‘outstanding’ design.

He said: ‘The CO2 Scraper is an outstanding example of the kind of ideas we need to look at now.

Germans Don’t Like Smog

Thanks to the BBCBerlin, Cologne, and Hanover have all decided to implement a neat way to make sure that their air is cleaner than other cities by using stickers. Drivers will have to buy stickers that denote how much pollution their cars emit and will be charge accordingly when driving in designated environmental zones. This is such a neat and simple idea.

Drivers now have to display a coloured sticker on their vehicle to enter the inner city zones. The colour depends on the pollutants the vehicle emits.

The cities are gradually phasing in fines of 40 euros (£29;$58) for anyone caught driving without a sticker.

Other German cities – but not all – plan to have such zones later in 2008.

The stickers – green, red or yellow – are mandatory not only for locals but also for foreign drivers, including tourists.

There is a one-off charge of five to 10 euros for the stickers, issued by Germany’s vehicle registration authority and authorised garages.
