so, there was a thread like this before where people asked " how come the sky isn't really blue" and stuff

well my dd and i were talking about global warming yesterday in the car ( like you do!) and onto electric cars.

so, i wondered why the motion of a car itself doesn't or i mean can't create electicity to be stored in a battery enabling it to go quite fast and - are you still with me - therefore perpetuating its own power with every journey it makes.

then i got to thinking abotu curent hybrid cars and i dont get this..

so taking my perpetual force creating electricity theory above - i would think that with a hybrid car you would have to use gas to start the motion ( therefore creating the electicity) then run on electriciy - but it doesn't work that way i dont think - i certainly dont understand how electricity is used at slower speeds - when my way seems to make more sense.

so my questions are
why the motion of a car itself doesn't or can't create electicity to be stored in a battery enabling it to go quite fast and therfore perpetuating its own source of free power to be used?

and

taking the above question in account - how come hybrid cars use leccy at slower speeds not faster?

( am off all week, and i have been thinking!)

LMAO....you got it!

You said "Only Nuclear energy, Geothermal energy and total energy don't have some input from the sun."
That total energy Smile

you have lost me now.

Blu · 28/03/2006 13:41

I know what nuclear and geothermic energy are, but not 'total energy'.

Blu · 28/03/2006 13:42

Oh, I see - total energy is the energy that is just 'in' things. From the atoms buzzing about, or something?

Bloody typos!

Tidal energy....driven by the pull of the moon and not the sun

but seldom on the grand scale that I manage Blush

Can I admit to having deeply regretted being unable to English at A level....clashed with physics. I also love music, played instruments etc.

So I do have an arty farty part of my soul Grin

And I can still do a diagram of the Kreb Cycle! Wink
I think the 'great divide' is false - I have often noticed that people with brilliant scientific analysis skills have brilliant capacity to understand and interpret art - i know several theatre directors with engineering or chemistry degrees.
And I don't think you could be an astro-physicist without some of the the mental capacities used by artists.

a beautiful thing, the Krebs cycle. My Phd supervisor did her Phd with Hans Krebs.

I always tell my A level classes that makes them Krebs' academic great grandchildren....so they had better get it understood Grin

i just told dh what i was learning on mumsnet today. he laughed at me and said "my head hurts! its nearly midnight for gods sake" but i forced him to listen to me anyway.

thanks mumsnet.
