Explain your project idea (2,000 characters)

Generally, more than 1,000 patents exist within solar energy, out of which 250 have been implemented, and out of which, some 200 of them works technically speaking, but, they are too expensive, thereby not feasible, or too complex, thereby they cannot be maintained, or, they work technically, while culturally they do not fit.

In example: In Japan, direct solar heaters without insulation, works well, as the Japanese culture takes shower in the evening, after work, before bedtime. In Africa (generally), the vast majority of Africans take shower in the morning, and therefore the solar systems not work there, as very few of the systems can preserve the heat over night.

Our system is designed with the aim of storing the heat over night in a stone chamber, insulated by soil.
Our system may be one of the least expensive solar concentrators, as it, in the 3D printed version, provides energy at 0.15 USD per Watt, while in the manufactured version provides energy at 0.03 USD per Watt. When using recycled plastics, the price gets under 0.01 USD per Watt.
Many solar energy systems are polluting, in that they do not fit a Cradle 2 Cradle principle. We are working into this system Cradle to Cradle, thereby it is our aim, over the foreseeable future, to establish full cradle 2 cradle, by ensuring that all our prefabricated parts are part of a Cradle 2 Cradle product.

We have a very unique business model, where we, instead of setting up business in all countries, which would severely delay the implementation by even up to a decade, we can expand extremely rapidly by simply linking up with the plastic industry in each country. We simply give away all drawings for free, against that we do the quality control.

Who are the beneficiaries? (1,000 characters)

We have targeted particularly those estimatedly 2 billion people, who can only afford charcoal and kerosene. Our solution is designed to be such inexpensive, so that it can financially compete with these two fossil fuels. In the period between 1978 and 1998 it is one of the worlds best documented terrible events, that use of firewood depleted Somalia of virtually all its forest.

Charcoal burning is - even in 2018 - depleting the scarce resources of arid and semi-arid bushes and trees. The Sahara desert is moving south with a speed of approximately 1 kilometer per year, a development largely spurred by the charcoal burning.

So the direct first-in-line beneficiaries are those most in need.

The beneficiary - directly in one way, but indirectly due to that they benefit from the 2 billion taking up this new water heating model - are the rest of the world. Each unit installed, resembles 290 trees planted. (Not 100% accurately, we will work that out precisely, together).

How is your idea unique? (1,000 characters)

As mentioned before, there are more than 1,000 solar energy innovations, however, they are expensive, clumsy, complicated, complex.

Ours is extremely simple, is stand alone, in that once installed, it runs until a component breaks (and we aim for 10+ years before that happens, due to our strongly simplified, refined design, reusable, user-changeable components), where we have built in security, anti-breakage, all-weather properties into the design enabling operations from dry deserts to wet, icy or snowy or stormy mountain-sides, with extensive use of structurally embedded features (ie. magnets) which are crucial but not "touchable" by weather. It has no physically "outdoor" electrical connections, as all such contacts are embedded (Reed relays etc.) or optical/digital.

In a nutshell - the idea is a concoction of 50+ expired patents plus some 40+ enhancements. Business wise, we give away 98% of the production simply to make this happen!

Idea Proposal Stage (choose one)

  • Prototype: I have done some small tests or experiments with prospective users to continue developing the idea.
  • Pilot: I have started to implement the idea as a whole with a first set of real users.

Organization Filing Status

  • Yes, we are a registered company.

In 3-4 sentences, tell us the inspiration or story that encouraged you to start this project.

Thomas Høyer and I (David Svarrer) started working on this Nexus 7 project 22 years ago. We have worked on it, since then. We are now ready to take it to the world. We find the OpenIDEO being one of the great, ideal platforms to do this. We are looking very much forward to the collaboration with the other after the deadline. We are ready also - naturally - humbly - to provide what we can of help / assistance if we can to the other projects as proposed. "Bring it all on" :-) - Greetings all!

Please explain how your selected topic areas are influenced, in the local context of your project (1,000 characters).

Provision of Sustainable, culturally fit, low cost, durable energy for Cooking, Sterilization, Cooling, Bathing, Washing from Europe to Africa. This is how:

*Culturally: Bathing, Cooking, Cooling when people need it, not only when the sun is up.
*Durable: Aiming at 10 to 50+ years durability in all weather. Repairable in modules, bits & pieces.
*Environmentally safe: Use of Cradle 2 Cradle processes/materials/business. 100% reusable.
*Inexpensive: The factory made solution competes price-wise with charcoal/kerosene
*Sustainable: We give away 98%+ of the production business to each country

See the attached presentation, we have a slide with 12 Directly Intended side-effects for the world, in terms of: Earth as such, Peace, Growth and Environment.

It is our humble take, that our 22 years doing this, has had at least some great prospect.

Who will work alongside your organization in the project idea? (1,000 characters)

We have worked with many so far - not exactly partners - but willing-to-be partners when this takes off.
We have worked with a range of suppliers of equipment, with a plethora of government and environmental people who have willingly volunteered to assist us - and who would continue to support the process.
We have received a tremendous support from almost anyone we have ever approached. I guess that we can muster more than 150 people to join in, when this goes hot.
In terms of organization - as mentioned in the slide show - we intend NOT to build a global organisation. We will outsource - for free - to manufacturers world wide who will produce the system - and we shall - for free - provide the production details.
Examples of such producers are those who right now produce consumer plastic. Our solar concentrator is intended as a consumer product, sellable via super markets!!!
THis will shorten the Time To Market to maybe 6 to 18 months, while going global could take 10 years+

Please share some of the top strengths identified in the community which your project will serve (500 characters)

We have spoken with Danish and Kenyan communities:
Denmark: Owners Associations are interested in promoting retro-fit for members to utilize solar energy 12 months per year, 8 hours per day.
Kenya: Solar heated water for use 24/7 is hot. Solar cooking outside of sun-shining hours is hot. Solar cooling via Carbon/Methanol or CaCl/Ammonium equilibria is hot.
We have discussed with Cement factories (Kenya), and paper mills, who are very interested. European ones refuse even to meet :-(

Geographic Focus

Global Focus:
Europe: Retro-fit
USA/Canada: New-fit
Equatorial Zone: Home/Industry fit

How many months are required for the project idea? (500 characters)

We expect to implement the first, initial, workable and full scale 10,000 Watt prototype in Denmark before end 2018, and the first full scale, 4,000 Watt prototype in Kenya, in 1Q2019. We expect to spend a vast amount of time

Did you submit this idea to our 2017 BridgeBuilder Challenge? (Y/N)

  • No

Dear Christina Schwanke - thanks a lot for your links despite you being very busy on your project! It is indeed not good to "grill" birds like this.

It is my general take without praising ourselves too much - that our model where we send the solar beam down underground, to a stone storage, is better. I will take up with Thomas, what we can do on OUR side, such that we do not - even in our diminished scale - face this problem.

We have - in our standard setup - likely some 8 to 16 mirrors concentrating into the same point. This produces a strong heat - but - even with 16 mirrors concentrating to the same point, you can still hold your hand in the reflection, for some 1 minute, after which you will feel too hot. It means that indeed one can fly through with no problem. For the eyes it is ALSO not a problem. Because on the retina, if you look towards the reflectors, all you see is 16 different images of the sun - on each their part of the retina. So there is also no risk of blindness as the strong light is so irritating so that one does not stand there looking into the 16 suns.

We will be checking out this, if we receive requests for higher concentration than a factor 16.

I share into the concern that we shall not create so called "renewable" energy, which as a side effect kills off animals.
