Hi!
Today is a wonderful spring day here in Bucharest. Hence I took a walk along the alleys of the largest park in Bucharest: Herastrau. For you this might be “nice to know, but why should I know” 
Well, wandering in the park I found myself nearby a place were people use to gather in the summer time and carry various activities, from just enjoying life to grass-sitting seminars, or shows, you name it. Then I suddenly observed that all luminaries were solar powered and… bang, an idea just came into my mind.
What if, during summer time I take on of my printers, arrange a way to power it somehow from the sun light and have some fun?
So, I provoke you to think about having a global project this summer, a project about a revolutionary technology as 3D printing is, about renewable energy and energy saving, about education and about living more exciting.
What do you think about?
All The Best,
Daniel
Cheers
