The newest generation of electric cars is a good match for the current generation of gas and/or diesel powered cars. The development is fast. With newest generation of Lio-Ion batteries and powerful electric motors these cars can be used for daily people and goods transports, have enough range and are faster than their fossil powered brothers. Therefore I have decided to create (and maintain) an overview of these new generation of electric cars.

Green power generated by and for the customer. Participants in the pilot thereby conserve the environment and, in addition, can save up to 150 euros per year.
Giving background of BigMama’s light measurements
Posted by Marcel van der Steen in Explanation No Comments»This article explains some general items mentioned in the light bulb measurement articles. Hope they shed some light in the darkness.
Lighting is important in people’s life. It can build a certain atmosphere or break it if not adequate. It can perform well in a working environment or it can totally fail in supporting it when not chosen well Also, it is an important energy consumer when considering halogen and incandescent lamps. Replacers are available, as this overview shows. Note that this is THE source for reliable information about light and light bulb parameters. OliNo performs independent light bulb measurements and publishing and publishes this information on this website for everybody to see.
So now you can save energy and find a good replacer for your energy wasting halogen and incandescent lamps. You can filter on efficacy, beam angle, light output and fitting type to facilitate your choice needed for your specific application.
If your lamp is not yet in the list, we can measure the lamp for your.
This article gives an overview of the lamps that are measured on different lamp parameters. One can look through the table given in this article for a small number of characteristics and a picture of the lamp. Clicking on the link brings you to the respective article.
A street lamp from the company LEDprojects. It is a big lamp, with a strong and robust mechanical screw fitting, which is of type E40. The mechanical design is very nice, the way the heat sink is integrated into the lamp. And the optical design is appealing; the lenses for every led are created with help of one piece of well formed plastic, very special.
It gives a lot of light, which is required for a street lamp. The lamp gets hotter than warm to the touch.
See this overview for a comparison with other measured lamps.
After seven months of work, from Feb 2008 to Aug 2008, she is finally born: BigMama! And it is her enabling OliNo to position accurately and repetitively the lamps that need to be measured. Together with some important other measurement tool this forms a flexible and fully automated test environment where a lot of interesting lamp parameters are measured.
This is the first post on the renewable energy site OliNo (English version). This is the next step after introducing the very successful Dutch OliNo website two years ago. The Dutch website has more than 25.000 of visitors per month and we are very proud of this. We now want to give access to this wealth of renewable energy information to a lot more people by starting an English version of the site…
Every recent house (build from the late 1980’s and up) has one installed: a forced air ventilation unit. Isolation is important, but what most people forget: good ventilation is also a must. Ventilation and isolation go hand in hand… In my house a system was also installed, with as a beating heart the JE StorkAir CMFe ventilation unit. The noise it emitted was disturbing (for me), and after a calculation I was amazed. This thing wastes lots of energy, and emits noise also…. Therefore I compared it to another ventilation unit (the Itho EcoFan 2) and… immediate upgraded this system for a brand-new Itho unit.
One year after using my first (small) set of solar panels, and many moments of measuring (weekly), the blue PV-virus took a grip on my life 😉 Combined with possibility (both financially as physically) to place more panels on the flat roof, the urge to use this space began to grow….
See and read here in this article where I upgrade a small-size (570Wp) installation toward a ‘slightly’ larger one (1.710Wp).
To make the most of this Christmas I decided two write my second column. In this article you can read about how to transform a 300W halogen fixture to one that allows an energy saving light bulb. I have done this just to demonstrate that it is not hard to find energy saving projects at home, if you are a bit handy.
