2050magazine.com – Issue 8: Food Glorious Food
It is always great to see what the folks at 2050magazine.com have for through-provoking articles. This time around they focus on the sustainability issues regarding our (global) food production. They also managed to highlight my car as a power plant ideas (see page 46).

‘Realizing the promise of DC Technology’
Recently I had the pleasure of being invited to speak at a conference in Prague ‘Realizing the promise of DC Technology‘. Central in the discussions there were the obstacles in the way of implementing a system-wide direct current voltage scheme, rather than the alternating current one. A DC system promises lower transportation losses and less conversion losses to name but a few. Since for example many household appliances already work on DC, while the outlet provides AC current. To allow the devices to function, they need to convert the AC current to DC. Because of this conversion a considerable loss occurs, somewhere in the region of 0.5 to 5%.
While switching to an all-DC system provides many advantages, there are many obstacles before the switch could take place.
In the video below I talk about the paradigm-shift that a DC system could be.

‘Cooperatie wil oudste waterkrachtcentrale weer in gebruik stellen’ (Dutch only)
Al tijden proberen we met lokale inwoners, ondernemers en overheden om Nederland’s oudste waterkrachtcentrale (in de stuw bij Hagestein) weer aan het werk te krijgen. Hiertoe is een cooperatie opgezet waar u uiteraard lid van kunt worden.
