Brief History of Hubble Space Telescope - undergoing final maintenance-and-repair mission before retiring in 2014
(quote)
The $1.5 billion Hubble rocketed to space aboard the space shuttle Discovery on April 24, 1990. It's named after Edwin Hubble, a pioneering American astronomer who furthered our understanding of other galaxies and demonstrated that the universe is continually expanding.
The Hubble's primary mirror, nearly eight feet across. A flaw in the mirror was discovered after the Hubble was in space; thanks to miscalibrated equipment, its glass had been ground slightly too finely at the edges. Though the imperfection measured just one-fiftieth of the thickness of a piece of paper, it distorted the Hubble's images. Astronauts fixed the problem in 1993.
About the size of a large school bus, the Hubble orbits at a speed of five miles per second, 353 miles above Earth. At that velocity it can cross the United States in about 10 minutes and circle the globe in an hour and a half. read more »

Brazil a leader in green power: 50% of cars able to use 100% biofuel, 70% of electricity sourced from hydropower
(quote)
*update* Mar 15, 2018
Brazil is the third largest renewable energy generator
In addition to clean energy, Brazil stands out for its biofuel production. Influenced mainly by ethanol, Brazil is the second largest biofuel producer in the world.
The largest national use of ethanol biofuel exists in Brazil (gasoline sold in Brazil contains at least 20% ethanol and hydrous ethanol is also used as fuel). In order for ethanol (ethyl alcohol) to be suitable for use as a replacement to petrol in its pure form, it must be distilled to at least 70-80% purity by volume before use.
Today almost 50% of Brazilian cars are able to use 100% ethanol biofuel, that includes ethanol only engines and flex fuel engines. Flex fuel engines are able to work with all ethanol, all gasoline or any mixture of both, giving the buyer a choice between price and performance.
Nature fed up with animals being ill-confined, force-fed? 1st cows mad, then bird flu, now deadly virus from swine
(quote)
While Indonesia's bird flu death toll climbs to 119, deadly strain (a nasty mash-up of swine, avian, & human viruses) of swine flu gets under radar of the immune system and pushes death toll in Mexico to 152 and climbing. "Residents [of La Gloria, Perote Municipality, Veracruz State, Mexico] believed the outbreak had been caused by contamination from pig breeding farms located in the area. They believed that the farms, operated by Granjas Carroll, polluted the atmosphere and local water bodies, which in turn led to the disease outbreak. 
According to residents, the company denied responsibility for the outbreak and attributed the cases to ‘flu.’ However, a municipal health official stated that preliminary investigations indicated that the disease vector was a type of fly that reproduces in pig waste and that the outbreak was linked to the pig farms. It was unclear whether health officials had identified a suspected pathogen responsible for this outbreak." read more »
Earth must be happy to see world's first heavy traffic road bridge made of wood, non-toxic, sequesters carbon
(quote)
On Saturday November 29th, the successful transportation and installation of the world’s first heavy traffic road bridge made from Accoya wood took place. The bridge, located in Sneek in the Netherlands, is the first wooden bridge in the world that can support the heaviest load class of 60 tons. Spanning 105 feet and rising more than 50 feet in the air, the structure will serve as a grand entrance to the city of Sneek.
April 20, 1887. Bouton and his co-driver won World's First Motor Race (on a steam-powered quadricycle), Paris, France

World's First Motor Race
Event Date: April 20, 1887
Location: Paris, France
The record books show that on this day Georges Bouton “won the world’s first motor race”. But it was a hollow victory and there was no champagne celebration – because Bouton and his co-driver were the only ones taking part. And, in fact, it wasn’t even a car. It was a steam-powered quadricycle.
The event was a “test” organised by the newspaper Le Velocipede to see if Bouton’s machine, which had boasted speeds of 60kmph, could make the 29-kilometre distance between Neuilly Bridge in Paris and the Bois de Boulogne.

Satellite solar panels in orbit to capture sun's rays 24/7 & wirelessly beam energy down to Earth
(quote)
Pacific Gas and Electric, which serves San Francisco and northern California, is to seek approval to buy 200 megawatts of energy from solar power firm Solaren. Within seven years, Solaren plans to send a satellite equipped with solar panels around 22,000 miles into space on board a conventional rocket.
Satellite solar cells would capture the sun’s rays 24 hours a day, without fear of cloudy mornings or dark nights. The orbiters then convert this solar power to radio-frequencies that transmit to ground stations in Fresno County, Calif. Once received, the radio energy would change into electricity and flow into the grid.
Sunlight in space is at least ten times more powerful than that on Earth, making orbiting solar panels far more efficient than those which are land-based. Solaren believes the technology could provide enough clean electricity to power at least 150,000 Californian homes.
