	For the 8th edition of the H&D Summer Academy "Connecting Otherwise" H&D invited four initiatives (DDDUG, Hackitects, MELT, NEWS) to develop a workshop program together for four different interconnected locations: Amsterdam, Aotearoa (formerly known as New Zealand), Berlin (+ online) and Seoul. In Amsterdam, H&D was accompanied by the Hackitects (Michel Barchini, Mary Farwy). Hackitects hosted a workshop, during which participants were invited to explore strategies to radically reduce the energy use associated with communication technologies such as the Internet ~~– more~~ specifically, DIY biotechnologies, that utilize bacteria found in local iron-rich soil are harnessed to generate and store energy.

	Look for reddish brown soil (rich in iron) near ~~river beds~~ and swamps, areas where water has a reddish color. Preferably collect deep samples not from the surface.

	About 1 liter makes 2 batteries. Ideally, you get it a few days before the workshop, but the soil should stay good for up to two weeks. It is always good to collect more mud than ~~what~~ you calculate, in case some spills during preparations.		About 1 liter makes 2 batteries.
