More consumer oriented, not fancy like improving ICEs

Is this means that science advancement in problem(in the United States) because the incentives of patents is just not working well ?

Thanks jrmichler , but I wasn't talking about engine modification, I started looking in engine modification then after research created something that energy efficient in another field ,maybe the misunderstanding resulted from my English language

Hello All : i uploaded some threads here asking about patent on engine modification , as i looked more in the discoveries , found out that it is already , discovered , but came up with another system to improve the energy efficiency (theoretical , experiment and a make shift prototype ) , now...

Hello all: As reviewing physics in my spare time , a scientific lecture series caught my eyes , by Dr. Steve brunton on his YouTube channel but had few questions Is the lecture series in correct order ? Second question what is the name of the book that he is using ? Best Regards H

Hello : I wasn't sarcastic:) I really read a book about vanadium, and other metals , it was for expanding the public knowledge I was in school at the time of the reading, the book claimed vanadium is hard to contain , I am just making sure that the information was right :)

Correction the researcher posted a video saying she is researching vanadium oxide , this may clarify things alittle

From my experience @Vanadium 50 is a PF Univers so I don't know of a method to contain it @berkeman when I visit the website without logging in I don't see your post on this thread ? ! And just to clarify I really read that , even mentioned that vanadium was used in wwii ! For metallic...

Hello all: Read a book long time ago about some metals and vanadium was mentioned that it , the book read that you can not contain vanadium in normal container because it will diffuse from that container is that correct Because I start seeing on social media Instagram for example people...

thanks for changing the title it was 2 am , and going to post the pages in few hours

tomorrow i will take a screenshot of the pages and paste them here excuse me in is near 2 am here

thanks but if they are constant shouldnt the derivative of C and e be = 0 in the book e also constant you will read in the above pages coefficients " it is usual to work with coefficients e rather than epsilon" the writer give the impression that he get e from deriving a 1st degree equation

Hello All : i am reviewing charlse kettle book introduction to solid state physics and came across an equation in the 3ed chapter which is a bit unclear hope that physics forums members can clear it more if that possible the equation 1st mentioned in the 3ed chapter page number 84 it is about...
