Idea – Phone Cylinder v1.0

As an imagination exercise why not try to design a new style phone. You can like me use the free Blender 3D software to do this. My idea is to model it using an elliptical cylinder over a flat screen. My original idea was to emulate an glass pearl with a deep color. But I think this design looks quite nice. Even if glass bends light. I believe if you can recognize the objects looking fairly ordinary then you would accept a little distortion. Apart from looking interesting the feeling of holding the phone should be better than with todays flat screen or half flat screen phones.

Poverty Fighting Idea – Job Café

The idea is very simple. Like there exists Internet Cafés with computers you can rent for your entertainment. Why can’t there exist Job Cafés with tools and machines you can rent for a small sum. Lets say the Job Café is equipped with sewing machines. Then people can make money using them without putting up any large sums themselves. I believe this idea could be used in poverty stricken areas.

Innovative Idea – Script Language Support For Salary Systems And Other Software Systems

My idea is simple and innovative. To increase effectiveness in system management many manual tasks have to be avoided. Especially if it involves many people. The idea is then to implement a dynamic feature in the software. What I had in mind is a script language like Python or similar. Python is just a programming language of choice. It could be others. The employee could then after some training program scripts to solve repetitive tasks. The computer could then since its very fast do this in seconds even if you have hundreds of small similar tasks. Such manual labor could otherwise take a week to finish. This idea would also avoid a lot of software development because you would no longer need support in making new special features. Also popular scripts could be shared within the whole user base. This means not everyone needs to be an expert programmer for this idea to work.

Simple example


For person in database

if person is available Monday 10.30-12.00 AND person has not worked full hours
print person


Idea – Flowers On A Winter Balcony?

Thinking about ways to enhance winter farming using added thermal energy I got this little idea for an invention. Why wait for warmer weather when you want to have flowers on your balcony. I think it might be possible to have plants in a transparent, tempered and insulated construction. If the natural light is insufficient during the dark winter months then some special LED lights would probably do.

Idea – A Past, Present And Future Method For Learning?

The idea is simple. I think we ordinary learn with past experiences trying to understand in an incremental way. What if the brain also can take advantage of a future step in this process of learning. If we know where the knowledge is going next then maybe the brain can take advantage of this and organize in a simpler manner. So the idea is that we teach the present step and just a little bit of the future step during the same time period. Because the future step has been presented a little the guess is that this step will be learned a little faster and more connected than with the ordinary incremental way. An example would be teaching about derivation and during the same time period present a little about integration.

I think this shows how you can create different learning paths and not just the forward incremental way.

Idea – Desert Greening Getting Some Kind Of Blueprint

A guess I often use is that for things there exists counter factors. Meaning that if something is very easy there is a another related thing that gets hard. Applied that to desert greening. I wonder if we are making it to hard trying to green flat fields. To me that is kind of similar to a farm field. Which is good for growing crops fast. But requires handling.

Also in farmland soil you don’t want a lot of rocks in various sizes. Again this makes it easier to farm. But what is the function if any of the rocks in the soil? Natural soil have rocks and stones so maybe they are needed to keep the soil intact and resilient or something.

Could the tech industry get involved in greening the desert? I mean there is a push for Internet Of Things. The desert is also a thing that really needs some attention.

How do we create a fail proof strategy for greening the desert? Could we monitor different solutions and the environment (wind and temperature and more) with new sensors. Could we use simple gaming AI for simulating living organisms. Could we then calculate different plausible blueprints?


Idea – Moisture Pump?

The idea is simple. Because there exist heat pumps why not guess an innovation based on that. Just simply by changing the word heat to something else.

However this was not how I guessed that there should probably exist a moisture pump. I got it from learning that wood is used in a hugelkultur to capture water. Then I thought. We got water damage in a summer house a long time ago and it takes a lot of energy to dry the wood.

This makes me suspect that maybe moist wood has the ability to draw more moisture from the air. Making it harder to dry it.

If it is so. Then wood could serve as an inspiration for a moisture pump. With a moisture pump that has a higher efficiency then condensation by cooling. We could use that in agriculture or desert reversal.


Idea – Man Made Molten Rock (Lava) As An Energy Storage?

Because volcanoes are a terrifying display of energy. Could this inspire a new energy storage. In comparison with pumped hydro. Could we develop man made molten rock or lava as a way of storing energy? Not tapping into a natural source but actually making our own molten rock.

Because the material is so very very cheap (rock) compared to Litium Ion batteries. I think this is definitely worth the research. Also using lava should mean no metal shortages.

Idea – Self Paced School Courses For Out Of School Children In The Slum?

Because of poverty and other reasons many children do not go to school. From my experience with MOOCs. It was easier to complete a course if it was self paced. The idea is therefore that maybe with the help of technology. We could have a self paced schools. To accommodate the special circumstances these children live in. So that the school is always an option even if you missed out of some of it earlier. Then why not turn nearby computer shops to learning centers. Maybe they could get government money for the management. Then in the learning centers the pupils could all watch different lectures in their own pace and get help from assistants.

Idea – Desert Reversal?

The idea is simple. Just by looking at a desert. I see plane fields of sand. This makes me wonder if deserts “prefer” non hilly grounds. If so could we then change a little the typology of the desert to better support life? Maybe the non constant ground elevation or other differences could give life a better foothold. Are there other constructions than the Pyramids that would withstand the desert? What would they look like and what effect would they have? After seeing ”Allan Savory: How to green the world’s deserts and reverse climate change” on youtube I wonder if one can optimize the surface so the number of grazing animals need not be that many.

Idea – Natural Aid For Cooling Of Buildings?

My idea is simple. Why not take inspiration from nature. We all know that when we sweat the water that vaporizes takes away a lot of heat. I thought maybe the water dew that is collected on plants have the same effect. If so could we mimic that ability so that the building surfaces could take advantage of the water in the air or maybe the increased humidity in the building. If surfaces like the window is changed to hold and take advantage of the dew. Maybe the energy requirement for cooling the building is then later reduced.

Idea – An Additional Parallel School Online?

I constantly read complaints that the quality in school is lacking. So why not take advantage of the Internet and the possibility for cooperation. Sharing of content and resources. Both material and teachers. The idea I had was if we could have a parallel version of a national school online. Common for all children in the country. A school that could compliment the traditional teaching or be a backup for when the local class or school temporarily fails or otherwise. A smart duplication of the resources for the students. So for example. If the math teacher is away some day. The children could continue their education online. Another interesting thing is if we could match students with different teachers. With online teachers this could perhaps prove a successful way forward.

Idea – An Additional Parallel School Online? Sharing of teachers.

Guessing – Virtual Cell Towers?

I’ve read that lasers can be bend. This makes me wonder if it is possible to have bend radio waves also. Imagine you could send concentrated radio energy upwards that would later bend to mimic a omni directional antenna. If such a thing is possible then you would not need that many cell towers and the cost would be much less.

Idea – Using A Intermediate Vector Representation For E-learning

I don’t think the free Wi-Fi project in Philippines need to be super fast right away. Even if it sure would be better. Obstacles like slow speeds are just problems that inspire new solutions. The idea I had borrows a lot from . Who has such a innovative solution for the problem of delivering educational content across a slow link by means of vectorization of the video. I think one could generate new videos if you do the vectorizing directly from writing on a tablet. The idea is then that students could make and share their own e-learning content. To better themselves and earn more confidence in their ability. Further I thought. You don’t need a new format for this to work. You only need to use the vector representation as an intermediate when transferring the video over a slow link. Ones you have got the vector video transfered. Some software installed on your phone or tablet/PC will just generate a .mp4 version. I think this way will be much easier to maintain since you don’t need to maintain the video player also.

Idea – Animated Visual Tracer For LibreOffice Calc?

The idea simple. Inspired by problems found in Calc type software. As a person who don’t use Calc on a daily basis. I could get some help inspecting a work sheet by initiating an animating so I thought. It would work like a step by step tracer. So that you can see where and how the data are being fetched from and calculated. So if you have a large project with many pages then the visual tracer would jump to the correct table. When doing the tracing. With this I think you could fix errors much more quickly than before.


Tip – Use A Cooling Bag On Wheels

With solar power being popular in some countries. I thought what would the problems be from using solar power for refrigeration. One thing I think would cause problems is the peak effect the refrigerator would consume when you put in new products. I wonder therefore if there is a way to reduce that demand. Maybe one way could be to maintain the cold in the product from the store.

A product I had in mind is a smart shopping bag on wheels that is also a cooling bag. This way you can buy a frozen food item which you later cook. Together with the cooling bag they will keep the temperature of the rest of the food down.

Maybe fresh food markets could increase their inventory. Also with unreliable electricity they could complement their demand with solar power that they together rent. Like M-KOPA for business.

Idea – Render To A Vector Image In Blender 3D

I think my idea is interesting. Could we render directly to a vector format in Blender 3D? If this is possible and gives good results then you could scale up the image without much pixel errors. Which is good for photo prints. I don’t mean that you should render the image with pixels and then convert it. Rather Blender should somehow generate a vector image directly. A guess would be a system of bitmap layers that combined could easily be converted to a vector image.

Another idea is to print out your rendered images in a photo print shop to paper. If you render at 6 MPixels or more it will look stunning.

Idea – Better Than Reality Or Photo Realistic

Looking at computer games I thought. Way, this looks better than reality. Then I thought. Whats the difference between the photo realistic images and these computer rendered ones. Improving the image quality will only give game graphics that looks more than perfect. One idea is just to add a noise filter. Like Gaussian Filter found in GIMP. With this the reality port-aid in the computer image will look more forgiving. Looking more like the  photo realistic photos we are used to. So my idea is to enhance the image with simple eye like limitations.


Idea – Easy Upgradable Speakers With Snap-in Speaker Elements?

The ideas is simple. What I want is a cheaper way to buy a new music experience. My idea is to offer speakers that you can easily upgrade. With snap-in elements you can do an upgrade yourself. The idea is that like the stationary PC your components age. So when you upgrade your PC why should’t you be able to upgrade your speakers? I mean I have speakers that are 15+ years old. Since they are heavy I don’t want new ones. I thought if you can upgrade the elements then I could still have the speaker box. Of course the speaker has to be adapted for such an upgrade.

Idea – Evolve The Battery By Developing For Extreme Environments?

The idea is to treat the development of a new battery as something like a mathematical search. What is an effective search strategy then?

I imagine that you can get new ideas by adapting the battery technology to different environments. Then the new ideas you get could then go back and inspire the whole network. The idea here is that by combining from a dual or multi environment approach. You would get new ideas more quickly than working only on one type of battery alone.

The network is just all the different battery technologies adapted to different environments. Examples of different environments could be the desert, the arctic or why not space. Here you have extreme heat, cold or pressure.

Idea – Helping People Living In Slums To Create Their Own Startup

I got an idea how the international community could help people living in slums to create their own startup or improve their capability to earn a better living. The idea is simple. Why not evolve Internet Volunteering. I imagine you could have a site similar to Indiegogo where you can match volunteers and the people in need of their assistance. Here the volunteers could cooperate with the people to build websites. Perhaps you could also have business related software together with the website. Adapted for mobiles. Online data would be secured if the mobile gets broken. This idea will benefit both the people and the volunteers since nothing beats a CV that makes a difference.

Thinking about this further. Maybe its better to educate them to build website and web software themselves. Even if the Internet speed is not great. It should be possible to get higher speeds internally between the Service Providers of the country. At least this should work within the same service provider. The idea is that one could build up experience from doing Internet jobs well before the speeds to different countries gets acceptable. With this you would get a more experienced Internet workforce.

Speculation – Parallel Guesses A Method To Accelerate Serial Computing?

The idea is simple. To accelerate computation that is not necessarily in parallel. I thought why can’t you use a parallel guesses instead. These guesses are parallel models that can predict some value in the future. Also the models take advantage or inspiration from the already true computed values. One of the models takes over when it guesses enough right values in a row. It is accelerated because the model is a simplification and only accurate withing a range.

To make it more robust. I guess that you can backtrack and verify a randomly selected small number of samples with the slow model. If there is an unacceptable error in the computation the it will start over from that place and skip the fast model for that range.

Speculation – Should Not Bees Have A Balanced Diet?

Since there are a lot different flowers. Could it be that bees actively selects flowers based on a variate of reasons? From an evolutionary perspective I guess that they select flowers based on what helps them and their offspring survive. Like fighting off disease. So I wonder if farming would benefit from a distribution of nearby flowers. Or what flowers you need for the bees to get a balanced diet for a selected type of crop.
