Sol4 Guide Ready for Early Adopters

Posted Sunday 5 July 2015 by Urs Riggenbach.

We’ve just finished the first version of the Sol4 guide and now all our Early-Adopters get to download it and start building right away!

As early adopter you get to build first. You get access to the construction guide, and details of the expected budget, time to build and construction notes and tips. On the hub you can ask questions and provide feedback at every step. By building before we release the guides for free, you help us validate the guides and make sure that they are as intuitive as possible.

Building the Builder’s Community
Our Early Adopters are living the mission of GoSol.org - taking our tech to new places. In the coming weeks we’ll be posting about these builders, who they are and what they’re up to. Click here to become a builder.

Join us for the next steps to "Free The Sun"
We are continuing our campaign with the aim to provide free material for people to build their energy independence. The next milestone is the Solar Oven guide, that turns a Sol4 into an oven for baking, roasting and many other activities.

Soon we’ll also finish the first version of the Sol1 guide. The Sol1 guide will also be the guide that we release publicly first, followed by the Sol4 guide.

Make it possible, join "Free The Sun"!

Let’s build!

Finnish Cleantech Delegation to San Francisco and L.A.

Posted Monday 30 March 2015 by Urs Riggenbach.

Last week I visited California as part of a Finnish cleantech delegation led by Ms. Lenita Toivakka, Minister for European Affairs and Foreign Trade of Finland. The business delegation was attended by industry leaders and newcomers in the Finnsih cleantech sector.

Finland hosts a surprising lot of cleantech companies, ranging from sustainable mobility solutions to cloud-based energy monitoring systems and a variety of net-zero technologies and products. In 2014, Finland was ranked second globally in cleantech innovations.

Mr. Juha Markkanen, Consul General to Finland in L.A. supported the delegation by pulling in various authorities from the state. It was distinguishing to see the support of the Finnish embassy. "Every embassy should do this", Markkanen says when asked about his proactive stance in supporting Finnish business abroad.

The highlights of the trip were a visit to Google with a pitch session at Google Green, visiting Tesla’s headquarters and taking part in the Nordic Green Tech Forum organized by Team Finland.

Team Finland is promoting Finnish industries and know-how abroad. Finpro, as a member of Team Finland, organized the trip. We want to thank FinPro and Team Finland for this excellent opportunity and we look forward to being part of upcoming delegations.
