VentureBeat reports that PowerGenix has developed a nickel zinc (NiZn) battery that has 35 percent higher power and energy density than a nickel metal hydride (NiMH) battery (used in hybrid vehicles), but is half the cost of a lithium-ion battery.

This is great news for scooter fanatics, who right now are forced to choose between cheap scooters with lead-acid batteries and expensive scooters with powerful lithium-ion batteries.

The latest town to get them is Anchorage, Alaska. The municipality, along with Cree, Inc, a maker of LED lights, are planning to change 16,000 municipal roadway lights with high-efficiency LED fixtures (about 1/4 of total streetlights).

Bigger Benefits Up North
Because Anchorage has 85 days a year with less than 8 hours of daylight, any benefit over the tradition lighting architecture are compounded. Read on for technical benefits of LED streetlights.

Benefits of LED streetlights
The LED fixtures are expected to use 50% less energy than current streetlights, which could save the city $360,000 per year at the current energy prices. The cost of the project is 2.2 million dollars. "The LED fixtures, based on performance-leading Cree XLamp(r) LEDs, typically last up to seven times longer than high-pressure sodium fixtures, allowing Anchorage to better utilize maintenance resources." And the quality of light should also be better, though people will need to get used to it at first.

Foster + Partners presented designs for a new waterfront development in Rimini. Revealed at a public presentation to the City last week, the proposal is designed to strengthen the relationship between the town centre and the seafront and to create a year-round attraction for an international tourist industry.

The scheme comprises a new seafront promenade with a mix of related activities and public spaces including a hotel tower, which will extend Rimini’s historic beach culture and continue the existing urban grain. The project celebrates Rimini’s tradition of green boulevards, best characterised by the Via Vespuci. The waterfront will be pedestrianised at certain times and will link directly to a linear public park – or green spine – which will provide much needed shade during the hotter months. This currently links the seafront to the historic city and will be enhanced with improved connections to the new promenade area.

A new hotel tower includes space for a Fellini film museum at its base. Its curving form anchors the wider project, while the building extends out to sea along a new 300m long pier, continuing the dialogue between the city and the water and referring to Rimini’s tradition of piers.

The scheme will use new technologies, such as rainwater collection and photovoltaics, to establish a long-term, sustainable commercial and environmental strategy for the town that is balanced with its rejuvenation in the short-term.

BAGHDAD -- In a city with constant electricity shortages but no lack of sunshine, the new buzz is solar energy.

Teams of engineers have appeared along major Baghdad roadways, bolting panels and bulbs to rows of towering steel poles to make solar-powered streetlights.

"We are lighting up the city with solar power," Sajad Hussein declared when queried by curious residents. "People say it is a gift from God."
Surging oil prices have fueled interest in solar power and other renewable energy sources in California and across the United States, where pressure also is building to reduce greenhouse gas emissions to fend off global warming.

Future generations may never have a sweet tooth to feed. John Mason, the executive director and founder of the Ghana based organization Nature Conversation Research Council (NCRC) believes that in 20 years times, chocolate will be much like caviar today.

"[Chocolate] will become so rare and so expensive that the average joe won't be able to afford it."

This fate of chocolate is terrifying news for two parties. The chocoholics of the world, but more importantly the producer countries that depend greatly on the sale of the cocoa beans as a portion of their GDP.

The main cause for the decline in cocoa bean growth is unsustainable farming in Ghana and other nations known for their cocoa plants. Also cocoa is naturally a rainforest plant that grows in shady conditions surrounded by a high biodiversity, until recently. Now, hybrid varieties have been grown on cleared land as mono-cultures and in full sun.

Although this hybrid seeds fills the demand for the short term, the soil quickly becomes degraded and the lifespan of plants can be cut from 75 or 100 years, to 30 or less. When the trees die and the land is exhausted, farmers must move on and clear more rainforest to plant cocoa.

The decline in West African cocoa is not only a problem for farmers and chocolate producers, one of which is Cadbury who uses 100 percent of West African cocoa beans to produce their chocolate, but environmentalists are increasingly concerned about the destruction of the rainforest for short-term gain.
