If you have a question that you do not see here, please email us with your question.

You may participate and submit as a team of 1 or a team of many. Either way, please register first to gain access to the platform, and then create a team profile. When you create a team profile, you will indicate whether you have team members already, are looking for team members, or are not looking for team members.

If you want to use materials or parts that are not available at Lowe's, contact the CWC Team, and we will make decisions on a case-by-case basis. If we give you permission to use such a part, you must still include the cost in your Bill of Materials (if it is recycled or reclaimed, provide a source that states its market value)

Yes. Material costs must still be reported.

We will have WAPIs available at Demo Day. Please let us know if you want one ahead of time and include the cost in your Bill of Materials ($2/unit)

All of the required documentation is due at 10 AM PST the morning of Demo Day (December 6th). If you want to add data recorded at Demo Day or any other additional comments/insights, you will have until Monday, December 7th at midnight to add to (but not edit) your submission.

Add these changes to your submission before Monday, December 7th at midnight.

Yes, this data will be used for judging, qualitatively in context of the entire submission. Our judges will use this information to evaluate the idea, its current performance, and its technical potential. Demonstrating excellent performance will be rewarded, and at the same time prototypes based on concepts with great potential that don't perform well due to fabrication issues will not be disqualified. Our goal is to encourage bold ideas and risk-taking, and to aim for functional prototypes.

Absolutely – we welcome contributions and collaboration of all sorts. One of our goals is to create a community of individuals passionate about this field and type of work, so the more the merrier.

Community engagement will be scored based on quality of contributions first, and quantity of contributions second. High quality contributions are ones that further develop the community's understanding of the challenge (problem framing, technology, fabrication, interaction, etc.) in a supportive, constructive, and generative way.

Yes. At least one of your team members must attend Demo Day and bring your prototype. If no one from your team can attend, consider finding a friend or colleague to represent your team and demonstrate your prototype.

Yes. We recommend teaming up with someone who is local to the Bay Area and could help get the prototype to Demo Day.

We will hold Demo Day regardless of weather. We recommend testing and gathering data on your device before Demo Day in case it's cloudy or you're unable to get data on Demo Day for some reason.

Water will be supplied via a hose. Please plan to bring whatever is necessary to demonstrate your prototype (buckets for input/output of water, ladder or stand to provide height for gravity-fed systems, etc.)

We will work with our Development Partners, Socialab and IWHA, to further test designs with the greatest potential. As all submissions will be made public following the challenge, we hope that the community continues to develop, iterate, and share their ideas.
