Dr Pete Armstrong, Mixergy – Episode 44 22.01.2020 43:57
I first met Pete Armstrong as he was pitching at the Ecosummit event in Berlin in 2018 and last year.

Kimmo Rauma, VP Danfoss Power Solutions – Episode 42 11.12.2019 48:25
I first became aware of the work of Kimmo Rauma, and Visedo from my good friends at Life Size. I’ve long believed in the electrification of everything, though I’m always open to be persuaded otherwise! There are of course some areas where that is far more challenging. Heat is one, and long haul and heavy transport are two such areas. Kimmo has been addressing long-haul and heavy transport for many...

So I approached an industry expert to shed some light on the life and uses of a lithium-ion battery. The answers even surprised me a little. Take a listen. About our guestHans Eric Melin is the founder of the London-based...
