The Dutch Windwheel

A 2014 plan was revived yesterday. The idea is to create a new sustainable landmark icon for the Dutch port city of Rotterdam: a wheel-shaped building with a giant hole at its center, for generating power, not with a rotor but with wires (“electrostatic wind-energy converter”). Height: 174 meter. Diameter hole in the middle: 108 meter. What started as a ‘wild plan in a pub’ has meanwhile grown out to something serious, with many parties involved.

Technical university Delft works at ‘Ewicon’, perhaps applied in the ‘Dutch Windwheel’ building.

‘Finger in the Dike’ Latest – Holland Struggles With Rising Sea Levels

“The beauty of waterland”. Drone pictures of Uitdam, 12 km north of Amsterdam. Note at [1:32] that the water level on the right side of the dike is higher than the houses on the left side of the dike.

Sigh of relief in Uitdam, the Netherlands. A commission has deemed it unnecessary to tear down the old picturesque dike in order to replace it with something more solid.

Yet, the entire dike between Hoorn and Durgerdam, protecting 1.2 million citizens, has been rejected from a safety point of view and will need to be reinforced. The people of Uitdam have demanded that this will not come at the cost of the village scenery. Price tag: twice as high as in the earlier plans. To be continued.

Ubitricity Has a Cheaper Method of Charging E-Vehicles

[source] The new way to charge e-vehicles?

The large-scale introduction of e-vehicles could very well imply the need for large-scale electricity charging stations along the way-side, like this situation in Berlin:


This could become quite costly, not to mention endless amounts of ugly car-chargers littering the streets of the near future.

The German company Ubitricity has come up with an idea to reuse old lampposts to achieve the same charging performance, but much cheaper and no impact for the way streets look like.

But nothing has decided yet as there are other methods in the works to recharge you e-vehicle… instantaneous at the pump, as usual!

China to Install 403 GW New Wind Capacity in a Decade

[source] Top 10 distribution of global installed wind power

Currently China has installed 169 GW of wind power, all onshore. According to the renewable energy analysts MAKE Consulting China will add 403 GW new wind capacity between 2020-2030. Note that the total average EU electricity production from all sources is 360 GW alone, although it needs to be remarked that real wind power is ca. 25% of name plate power.

Nevertheless, China, the giant that is awakening.

Price Utility Solar to Drop with 27% in 2022

Already prices for utility solar are below $1/Watt in 2017. According to a new report by GTM Research price will fall further with 27% over the coming 5 years time.

Hywind Scotland Floating Wind Turbines Pilot Completed

A small 30 MW wind farm has been completed in the waters of Stord, Norway and will be towed to Scotland. The project consists of five 6 MW wind turbines. What makes the project unique is that the turbines are floating, ensuring that shallow water is no longer necessary for offshore wind to work.

German Gode Wind 1 and 2 Offshore Wind Farms Go Live

DONG Energy has officially inaugurated the German Gode Wind 1 and 2 offshore wind farms, together 582 MW.

Next DONG projects in the North Sea: 240 MW OWP West, 240 MW Borkum Riffgrund West 2 and the 110 MW Gode Wind 3, total 590 MW.

Solar Team Twente Presents “Red Shift”

This year the University of Twente in the Netherlands will again participate in the World Solar Challenge in Australia.

The students have presented their new solar car called “Red Shift” at the Twente Airbase in the presence of the Australian ambassador, who returned home with a bottle of “Twent’s bier” [0:57]. In 2015 Twente ended second. Twente is confident that they will win this year.

Prof. Olaf Schuiling has a Solution for the CO2 Problem

2009 Shell subsidized olivine test in Brennels/Flevoland [Google Maps]

Olaf Schuiling (1932) is an emeritus professor in geosciences at the university of Utrecht in the Netherlands. He has a background in petro-science and geology and has spent some time at Princeton as a NATO research fellow. Between 1972-1997 he was professor in geochemistry and experimental petrology in Utrecht.

Prof. Olaf Schuiling’s main claim to fame is that he believes that he has the solution for global warming, caused by increasing concentrations of CO2 in the atmosphere, due to burning of fossil fuel: olivine:

This month, Schuiling has published his new book Olivijn, de steen der wijzen (Olivine, the stone of wisdom). Schuiling especially targets the idea of sequestring CO2 in the earth. Olivine will provide the solution for a fraction of the cost. One kilo olivine can bind 1.25 kilo CO2.

Schuiling wants to use the abundantly present mineral olivine (Mg2SiO4/Fe2SiO4) to reabsorb CO2 from the atmosphere. The idea is to grind olivine and let it react with water and CO2 from the atmosphere. The resulting bicarbonate dissolved in water will flow to the sea, where it will settle out as limestone and coral.

Schuiling proposes to pulverize an olivine mountain of 7 km3/year and spread the powder over land and beaches. When the olivine has done its work it can be plowed under and as such enhance the fertility of poor soil. Huge olivine reserves exist in China, India en Brasil. Cost 10-15 euro per ton olivine. Sequestering CO2 like was proposed and cancelled in the Netherlands in contrast costs 70-100 euro/ton CO2.

Olivine is relatively equally distributed over the earth’s crust, so there is no need for large transportation effort. All it takes is deposit a layer of 3.5 mm olivine powder on an area of 2 million km2, that’s four times France, every year, to neutralize that year’s global CO2 emissions.

Schuiling is participating in the Al Gore/Richard Branson VirginEarth Challenge, a contest for offering a solution to CO2-sourced climate change and has made it to the final 11:

[] – Virgin Earth Challenge: How Goes It?

Evaluation: what is lacking is an evaluation of the energy cost to mine, grind and disperse olivine. As far as we are concerned it seems to make more sense to get away from using fossil fuel poison first, as proposed for instance by the European Union renewable energy policy. It doesn’t make sense to ‘mop with the tap wide open’, so to speak. As a measure of last resort this kind of megalomaniac-sounding scheme could be considered to reduce atmospheric CO2 levels after the transition has been accomplished.
