In 2008 Guisepi bought a short school bus, converted the engine to run on vegetable oil, and created stunningly beautiful interior with recycled furniture. Today the bus “Edna Lu” is a solar home for Guisepi and his partner Ally.

The bus is also a mobile tea house! serving free tea to anyone and everyone, wherever it goes.

Watch Guisepi giving a tour of his radical tiny house, and showing the ins and outs of waste vegetable oil. In the end Guisepi tells the story in his own words, explaining his motive behind free tea. I love the reflection on economy, and “genuine human connections”!

You can understand Guisepi and the teabus more from their website’s FAQ. The site is, and Facebook and Instagram handle is freeTeaParty.

Humans Awake is a series of video interviews by Cheng Liu, to tell you about the people she meets on the road. Friends, strangers, travelers and everyday people from all walks of life, share a bit of their story and inspirations. These people are the reason why I have faith in humanity. I hope this brings you positivity too. Follow the whole series at or Most people will be from east coast of America, occasionally other countries too as I travel there.

    Great design – a total transformation.

  2. Nephtys80 says:

    Thank you so much for creating this series, great introduction to the topic! The site where we plan to build our house has a line of deciduous trees – not on the property – blocking sunlight from about 3 o'clock in the afternoon in summer, and presumably a lot earlier in winter. We may only be allowed to build a one-storey house, we're still waiting to hear about building regulations for the area: does it still make sense to use passive solar in this situation, or is that just not enough winter sun?ย

    Great series of informative video's. Thanks for posting. Interesting too how we can get of the grid quite easily if we wanted to.

    He is very cute but I want to separate his mono brow. Maybe his gf likes it, who am I to say?

  11. Kath Butt says:

    This book [link here >>> ] got me thru the design and installation of a complete off-grid system for my lake cottage. The process of site evaluation, system component selection, wiring, etc. is complex, but with a lot of study and this book, I ended up very happy with the results. Everything you need to know is here. I recommend it for anyone who is starting with little solar panel knowledge and wants to end up with a whole house system.

  18. Deborah Davis says:

    What a beautiful and amazing idea! I very much enjoyed your video and hearing your wonderful plan. In this digital age we are forgetting to make REAL connections, such a simple change that can change lives. Bravo – can't wait to see your book(s) in the near future. You remind me a lot of a modern day hippie – and please believe me I say that in a COMPLETELY good way!
