If you can prove something like a hydrogen society can work in a city like Tokyo, then it’s a matter of how do they scale it, how do the Japanese ensure that all the ancillary consequences have been addressed, and you only really do this by testing it out.
Japan is moving faster than expected toward an hydrogen energy future. Prime Minister Abe has become a vocal advocate for hydrogen – both to stimulate developments in technology and to help the resource-poor nation lower greenhouse gases. With Japan relying more on fossil fuels since the shuttering of most of its nuclear reactors after the Fukushima disaster almost six years ago, it’s a push that’s gained more urgency.
Toyota is at the forefront of Japan’s efforts to use hydrogen and fuel cells to power cars, heat homes and keep factories running. Other companies pursuing the technology include Panasonic Corp, Toshiba Corp and JX Nippon Oil & Energy Corp. Read More
Working of the capacity down pipe (1, empty; 2, filling-up; 3, over-flowing; 4; full; 5, drained)
A case study in Manchester with different solutions for water infiltration and retention systems, showed that soak-aways and infiltration trenches are generally less preferred than capacity down pipes, ponds and filter strips.
And this wateringpipe – the capacity downpipe (CDP) – works even better.
Wattway, part of the France Colas constructions company, announced that four SolarRoad pilots will be built around the world in 2017.
Bloomberg December 4th:
(…) Colas SA, a French engineering firm, has designed rugged solar panels, capable of withstanding the weight of an 18-wheeler truck, that they’re now building into road surfaces. After nearly five years of research and laboratory tests, they’re constructing 100 outdoor test sites and plan to commercialize the technology in early 2018. (…/) Read More
Miners use their bare hands to filter out precious minerals using a sluice. These countries can be compensated of we agree on international quotas for minerals
Critical minerals are running out too fast: there should be quotas
Last week, Theo Henckens has been promoted on this worrying thesis. “We need a kind of international agreement on minerals.”
Molybdenum is a mineral that is essential in the production of high-grade stainless steels. But within 80 years Earth will be running out of molybdenum, like many other major minerals. By the end of this century there will be a shortage, unless the reuse of molybdenum will be drastically increased. Read More
The Hyperloop capsule will be ‘launched’ next June on the 1.6-kilometer test track. The test will start with a 4-second acceleration at 2,4 g, followed by a 10-second ride and an equally brisk braking procedure.
Students at the TU Delft, developed a futuristic tube transport system called the Hyperloop. In future we can travel at the speed of sound. Read More
Hundreds of volunteers helped to restore coast Alabama, building oyster reefs
We need to protect our coasts from global warming and – because of that – the sea level rising. But should we only use concrete seawalls?
Why not use nature against nature. Or a combination with classic engineering?
It’s a beautiful, natural coastal protection and soften shoreline defenses are multifunctional. It’s attractive to all kind of sea lives, tourism, fisherman and therefore a whole industry behind. Let’s have a look at alternatives. Read More
how to keep the climate comfortable in buildings, without energy-intensive installations
Do you also have dry eyes and headaches in your office building? This new Facade System allows a building to ‘breathe’. Tobias Becker used biomimicryfor a pleasant indoor climate.
The German engineer Ing. Tobias Becker has developed a glass facade system that requires minimal energy to generate a pleasant indoor climate. The system allows air through holes and makes buildings ‘breathe’. Read More
Daan Roosegaarde introduces the Free Smog Tower: a 7 meters high tower that creates smog-free air in the area.
“It’s my job to look around, and find new proposals to solve global issues. I have been involved in fashion and highways. And since 2014, I am involved in smog.”
Daan Roosegaarde introduced the ambitious idea for the Free Smog Tower. He started a Kickstarter Project with the goal to built a 7 meters high tower in Rotterdam that creates smog-free air in the area. Read More
One of them is a school which even will deliver electricity to the grid
The other is an Environmental Education Centre (picture) is housing offices, a restaurant, exhibition halls and a doctors practice. But for both of the buildings, the solar chimney is The Big Innovation!
