Idea – Does Physical Bodies Emit Invisible Light Dependent On The Velocity?

My idea is simple.

I assume a cooling mechanism in the physical world is emission by light. That is. Energy (light) removal from a body.

A thought experiment would then be that physical bodies emit invisible light dependent on its kinetic energy.

I guess this because if there is a maximum velocity for mass then any energy input that would result in a higher kinetic energy would have to be removed.

The fastest way to remove energy is by light. Hence bodies should be able to emit a kind of light dependent on the velocity.

Idea – Dedicated Hand Held Device For Scratch Powered By The Raspberry Pi ?

The idea is simple.

Why not put together a dedicated device running Scratch games powered by the raspberry pi zero chip.

I think you need to make a dedicated product if you are going to include batteries. So this should just be powered by Linux and the raspberry pi. Not for the kids to put together.

Then you have your raspberry pi 3 to program the games and the dedicated hand held game device to play on.

I think this could be very interesting.

Idea – Smart Path Recognition

Today was a sad day. Not only for Russia but for the whole world. I can’t say I know Russia. I mean its a big country and it should not be this way. I believe we need all the brain power we can get in this world. To adapt to climate change. To innovate.

I think you can innovate much faster and generate new information by looking at previous accomplishments and writing up hindsight stories. If they had done X and Y they would have figured out the hard part much easier. So if you can make the innovation process sound much smarter than it was then its a good thing.

By reading perfected innovation processes. Those in hindsight improved stories then your brain would learn to recognize smart paths.

Idea – Vertical Crops?

I was wondering if one could adapt the crops to a vertical grow path. Instead of layering soil in the air for vertical farming. That is. Instead of vertical farmland we have adapted vertical crops. Similar to vines, bushes and trees.

Also since rice is so important. Are there variates that could grow vertical?

Is there a better yield for bigger rice grains that you can later break up in smaller parts. That is. If you have a god rice variety that outputs twice the size of an ordinary jasmine rice. Why not just break such rice grains in two.

Idea – Link To The Job Seekers CV From The Mobile Phone Stored QR Code ?

The idea is simple.

Could job seeking become easier if you take advantage of the Internet and QR codes?

The idea is that job seekers could have their CV on a website and carry a generated QR code as a link. The idea is that the CV or PDF is automatically transferred to the employer just by them scanning a QR code.

Employers could set up self scanning service device for the QR codes and job seekers could send them the CV from it.

Idea – Record Your Exercises For Your Motivation

The idea is simple.

Why not record your training or exercises for future reference and motivation. An idea for a startup is to have some professional review the uploaded private videos to help and pep talk the participants. This idea is meant as a motivation tool in pursuit of a healthier life style especially for those adults with a weight problem. Being overweight raises your risk for diabetes . Check out .

Political – Sharing Economical Cost By Switching To More Beneficial Government Loans ?

This is not my field. But I think might have something of a peace project type of an idea.

I wonder. Could the initial cost of taking in many refugees be shared among the countries of the world? The idea is that more countries would be more inclined to do so if this is the case.

Then maybe an idea would be that there are beneficial country size loans or write offs that could be offered by the world community.

Since this should be an efficient use of money. There should be a requirement for these loans and write offs that the refugees get into the workforce in a short time period since arrival.

I believe this could be seen as a peace project and as an investment in people.

Idea – Stone Age Inspired Energy Extraction ??

My idea is simple.

Why not see if electricity powered friction could be used together with burning of coal, gas or other fuels.

Philosophically this represents an option so it should be beneficial for something. Like energy extraction maybe.

In the animation the rectangular box is the thermo photo voltaic cell. The device that turns heat into electricity. The cylinder is used as the heat absorber from the source and I put some friction generating cylinder on the other side.

The cylinder that makes the friction is suppose to rotate at a high rate. Powered by an electric engine making friction. Friction might be used for getting those high temperatures for the TPV cell.

I don’t know what the resulting effiency will be but maybe friction could enhance energy extraction. I mean friction is very connected for driving out heat from a material. Its not a perpetual motion machine though.

However I wonder what the temperature could be for the sparks generated from the friction interaction. I mean. If you light a match in strong winds it will quickly burn out. Spark elements are very small and seem to last in high velocity.


Idea For Free And Open Source Software – Generating Realistic Objects/World From 3D Block Objects Using Machine Learning

My idea is simple.

Using machine learning it should be possible to generate a more realistic 3D model of a simplified 3D block object.

The blocks are just simple primitive 3D objects like different shapes of boxes and other primitives like planes, spheres and more.

The idea is that you put together the block objects into a crude model. Then you label it and let the machine learning software generate a more realistic model. This based on its previously trained samples and target models.

So if you build a house with these big blocks of shaped boxes then label it as a house or label it using a target image. The target image could be the inspiration data. The machine learning software will then generate a realistic looking house with much more 3D polygon detail.

Imagine something like a 3D game where you first build your world with big blocks and then let the software generate a realistic world from it. Pretty nice.

Idea – Does The Universe Use Distributed Error Information ?

I wonder if action at a distance could be made possible if you view an error as something that could be distributed. What I mean is that if you got a single error in the entire universe. Then its damn hard to find it. My idea is that information about the possible error that can occur in action at distance is radiated outwards in the universe. This from the start of the creation of that possible error. That is. I believe the universe shares risk information.

The below image explains the idea. Compare the two cases. One with no distributed error information and one with it. The universe with the error information is much more likely to be able to correct the error. The other universe will have to magically find the error with nothing to lead it right.

Climate Change – Rice

My girlfriend is from the Philippines. There everyone eats rice. Three times a day at least. As rice is the most eaten food in the world,  especially in Asia. I was wondering. In the future. If farmland is declining all over. Due to climate change.

Could we come together in the world to help grow rice wherever its possible.

So the idea is not to only have climate change resistant crops but also climate ready farmland.

Math Idea – Dependent Noise

Was playing with an idea. Just a half somewhat abstract idea.


What if a time series of data is not only the signal and noise. What if you have a signal, independent noise and dependent noise.

The dependent and independent noise can perhaps be like the image below.

Some of the noise has some mean characteristic. In this case the dependent noise goes around the circle doing its thing. Where as the ?independent noise just sits still and surrounds any object.

Then I wonder. Could you take a time data series and separate it into a signal, independent and dependent noise?

I think dependent noise is noise you can lead to an object. Be it a real object or why not some calculated object. In any case you can say the noise contribution belongs to this object.

Energy Idea – Using Thermo Photo Voltaic To Simplify Any Energy Extraction Process ?

The idea is simple. Because radiation is a much better energy carrier than mass. That is. It can hold much more hotter energy with it. Where as mass has different limits.

The way I see it. If you use mass like water. You are in fact using a poor functioning go between battery. This is similar to charging a power bank and then to charge the phone or computer with it. The efficiency this way is very bad.

I wonder if you just could use thermo photo voltaic to convert extracted energy to electricity directly instead. Close to the source or perhaps you could use a molten silicon based thermo energy storage device to capture heat at higher temperatures and then convert it to electricity using thermo photo voltaic.

So you have a smaller coal based power plant with molten silicon based thermo energy storage and thermo photo voltaic cells to convert the heat to electricity.

Startup Idea – Climate Change Mitigation Strategy

I could be that we are very unprepared for the effects of climate change. Foreknowledge costs money and I think I got an idea to minimize future demand and supply.

The thing is. I think we could achieve better climate change mitigation. Simply by predicting and preparing for the many different businesses and more needed in a future affected by climate change.

That is. We can think of the future needs or demand already now.

A start could be to simply plot the demand in every business sector as a function of say the temperature and see what needs to be done.

Math – Make Use Of False Positives In Optimation ? Fill-function

So I had the idea that maybe biomimicry exist in mathematics also. Maybe it does but I thought what would I do to enhance optimation.

If you have a function F(x,y) and you want to find x and y that minimizes this function. You probably don’t get the best values at the beginning. Call them false positives.

What I wonder is if you can simply add a fill-function that spans over the domain and prevents the optimation from looking or going towards those false positive positions.

F(x,y) -> F(x,y) + fill1(x,y) + fill2(x,y) + fill3(x,y) + …

I don’t know what the different fill functions should look like though. The idea is that this simplifies F(x,y) in search for the best values for x and y.

Math Idea – Similarity Series ?

I speculate that maybe it would be possible to build a series with similarity as the base function. So you have.

[x0, x1, x2, x3, … ]

where x1 is most similar to x0 and x2 is most similar to x1 and x3 is most similar to x2

but all x are unique.

Even if this is somewhat inaccurate. There should exist something like an evolutionary like math series.

So if you start with triangle and a square I imagine you could end up with a circle.

Another idea is the guessing series

1 2 3 … Filling in the rest is pretty easy.

365 52 … Filling the rest is easy but it shows a guessing series need preference data.

Math Idea – Noise Detection As An Error Function In Machine Learning

My idea is simple.

So I was wondering. What is new information?

Inspired by this I realized that. If you recognize noise in the mix of frequencies then part of it doesn’t form information. Or at least this the guessing sentence with delivery value.

You can transform information so it sounds like noise but then it is not directly understandable information anymore.

So my guess is that its possible in theory to generate new kind of information by just mixing sin wave signals and check for noise.

From this little thought experiment my guess is that you can generate new type of error functions. Here the error function is a noise detection function.

Math Idea – My Take On The Simple Perceptron In Machine Learning

When looking at the wikipedia article on the Perceptron supervised binary classifier. That one about machine learning. I just realized that the binary classifier defined as.

f (x) = { 1 if dotp(w,x) + b > 0
0 otherwise }

To me this just looks like fractional voting. Summation of a list of for and against values.

From this I can possibly come up with a new guess of a classifier.

My target for this is one that “converges” quickly or not at all

I was thinking that maybe I could have a list of previously calculated values of f (x) as the voting samples. Then use this to ”time” series predict where its going to end up. Either 0 or 1 in the time range you are pretty certain of.

My guess is that this puts a boundary value for the weights to adapt to. Within some “time” period.

This way you should be able to reduce the number of weights you need to calculate in the ?hidden layers. The weights need not converge to a situation where the its unnecessary certain what the outcome will be.

Speculation – Creativity As Set Generation Within A New Group

So an easy way to learn creativity is to learn how to generate information. Information that is recognized to belong to certain group. Like a particular music genre or science field.

I believe the driving force is that the group is uncharted. Meaning that you will have to create the building blocks of the group or learn them.

A somewhat uncharted area is needed because otherwise it would feel like your sampling already created stuff.

An example of a field within programming that generated new creative learners are block programming. Programming using drag and drop blocks like in Scratch.

From this I guess that you can creative new fields by changing the input again. So why not speech programming. Small programs using your voice or maybe a pseudo code trainer. Where you move blocks of sentences to its right row position.

Idea – Verification Hash String In The .CSV Data Files?

Data is important. Its used everywhere. I suggest maybe that therefore .csv files have a hash string to verify the data content. CSV files are just the non binary text files containing the data. So the beginning of the file a hash string could be included.


Here the data is defined beginning at row 3 to the end row. The SHA1 is calculated for the data section only and then compared with row 1 SHA1: which should be the same string.
