Make Crosswalks More Visible

Good simple idea. And then executed well – for nighttime at least. Crosswalk lights up when in use giving drivers a more visible clue to stop.

Repair Cafes in The Netherlands

Repair Cafes in The Netherlands Give Life Back to Broken Objects

A new brand of DIY self-sufficiency is spreading across The Netherlands. Skilled craftswomen, mechanics, seamstresses, and handypersons are banding together to resist disposable consumer culture. It is the rise of the Repair Cafe, a place where neighbors get together to extend the life of their material belongings. “Fixers” mend clothes, restore furniture, rehabilitate electrical appliances, and enjoy each other’s company while industriously toiling away. The first cafe was founded by Martine Postma in Amsterdam in October of 2009. Today, there are 20 fully operational Repair Cafes, and 50 more in the planning stages.

I really like these efforts. We throw away too much stuff that has plenty of useful life left. Also it is a great way to build community. And it is an interesting way to learn about products we use everyday (both by fixing them and having your items fixed). The throw away culture is something we should aim to change. By these actions and also by engineers designing products to be fixed instead of thrown away. I donated to a similar fixer collective in Brooklyn via Kickstarter.

Dutch Kids Pedal Their Own Bus To School

The Dutch are bicycle fanatics. Almost half of daily travel in the Netherlands is by bicycle, while the country’s bike fleet comfortably outnumbers its 16 million people. Devotees of the national obsession have taken the next logical step by launching what is likely the first bicycle school bus.

Built by Tolkamp Metaalspecials, and sold by the De Cafe Racer company, the bicycle school bus (BCO in Dutch) is powered entirely by children and the one adult driver (although there is an electric motor for tough hills). Its simple design has eight sets of pedals for the kids (ages 4 to 12), a driver seat for the adult, and three bench seats for freeloaders. The top speed is about 10 miles per hour, and features a sound system and canvas awning to ward off rainy days.

They have sold 25 of the busses so far for $15,000 each.

Underwater Pedestrian Bridge

The Dutch water line was a series of water based defenses conceived by Maurice of Nassau in the early 17th century, and completed by his half brother Frederick Henry. Combined with natural bodies of water. The line could be used to protect the economic heartland of the Dutch Republic behind difficult to cross water barriers, when in danger.

The Fort de Roovere was part of this defense. In 2010 the fort was renovated and the moat revived with a small extra bit of engineering: a sunken pedestrian “bridge.” Where once engineers used ingenuity to use water to keep people out, now engineers used wood to let people experience the moat while still reaching the fort.

Robot Tennis Partners Coming Soon?

The robots in the video, and many more, are being tested at the Flying Machine Arena at the The Institute for Dynamic Systems and Control, Department of Mechanical and Process Engineering, Swiss Federal Institute of Technology – Zurich.

They also usually have a number of challenging projects available. Qualified, motivated students should visit the Theses/Projects page and contact them to learn more. We need more people working on these types of things so I can have my robot basketball team available when I want to play.

Nearly 45% of the electricity in Portugal Comes From Renewable Sources

Portugal Gives Itself a Clean-Energy Makeover

Five years ago, the leaders of this sun-scorched, wind-swept nation made a bet: To reduce Portugal’s dependence on imported fossil fuels, they embarked on an array of ambitious renewable energy projects — primarily harnessing the country’s wind and hydropower, but also its sunlight and ocean waves.

Nearly 45 percent of the electricity in Portugal’s grid will come from renewable sources this year, up from 17 percent just five years ago.

While Portugal’s experience shows that rapid progress is achievable, it also highlights the price of such a transition. Portuguese households have long paid about twice what Americans pay for electricity, and prices have risen 15 percent in the last five years, probably partly because of the renewable energy program, the International Energy Agency says.

Norway Reduces Infections by Reducing Antibiotic Use

Norway conquers infections by cutting use of antibiotics

Twenty-five years ago, Norwegians were also losing their lives to this bacteria. But Norway’s public health system fought back with an aggressive program that made it the most infection-free country in the world. A key part of that program was cutting back severely on the use of antibiotics.

Now a spate of new studies from around the world prove that Norway’s model can be replicated with extraordinary success, and public health experts are saying these deaths — 19,000 in the U.S. each year alone, more than from AIDS — are unnecessary.

“It’s a very sad situation that in some places so many are dying from this, because we have shown here in Norway that Methicillin-resistant Staphylococcus aureus [MRSA] can be controlled, and with not too much effort,” said Jan Hendrik-Binder, Oslo’s MRSA medical advisor. “But you have to take it seriously, you have to give it attention and you must not give up.”

The World Health Organization says antibiotic resistance is one of the leading public health threats on the planet. A six-month investigation by The Associated Press found overuse and misuse of medicines has led to mutations in once curable diseases like tuberculosis and malaria, making them harder and in some cases impossible to treat.

Now, in Norway’s simple solution, there’s a glimmer of hope.

Cuts for British Science

Cuts mark ‘sad day for British science’

Britain’s physics community is reeling from a “disastrous” day of funding cuts that will force scientists to withdraw from major research facilities and see PhD studentships fall by a quarter. Space missions and projects across astronomy, nuclear and particle physics are being cancelled to save at least £115m, the Science and Technology Facilities Council (STFC) said today.

Fellowships and student grants for PhD projects will be cut by 25% from next year. The announcement has appalled senior physicists who warn the cuts threaten Britain’s future as a leading player in science.

In February, Gordon Brown delivered his first speech on science in Oxford and stated: “The downturn is no time to slow down our investment in science but to build more vigorously for the future.”

Politicians like to talk about funding science investment. And they do so to some extent. However, they are more reluctant to actually spend money than to talk about the wonders of science. Several countries in Asia are not just talking, they continue to invest, large amounts of money. The USA seems to be willing to put some money (not the kind of funds paid to protect bankers bonuses but significant amounts). Still the amounts the USA is investing is, I believe, falling as a percentage of global investment.

European Eels in Crisis After 95% Decline in Last 25 years

Eels in crisis after 95% decline in last 25 years

But the action the Environment Agency is about to take is upsetting those who rely on the eel for their livelihoods. A ban on exporting eels out of Europe – they are a popular dish in the far east – is proposed, along with a plan to severely limit the fishing season and the number of people who will be allowed licences.

It seems pretty obvious we have over-fished the oceans. Without effective regulation we will destroy the future of both the wildlife and our food source.

The eel remains one of the world’s most mysterious creatures. It is generally accepted that European eels – Anguilla anguilla – are born in the Sargasso Sea near Bermuda.

As leaf-like larvae, they are swept by the Gulf Stream towards Europe, a journey that may take a year. When the larvae reach the continental shelf they change into “glass eels” and in the spring begin to move through estuaries and into freshwater.

The animals develop pigmentation, at which point they are known as elvers and are similar in shape to the adult eel. Elvers continue to move upstream and again change colour to become brown or yellow eels.

When the fish reach full maturity – some can live to 40 and grow to 1m long – they migrate back to the ocean. Females are reported to carry as many as 10m eggs. They return to the Sargasso Sea, spawn and die.
