Easy Pete......it's only arithmetic. You(or your calculator) can multiply, can't you?


This is nothing to bother Steve with, he can do fourier transforms and other esoteric stuff.



Look up the efficiencies, they will be expressed as percentages. Key them in as decimals(88%=.88). Round up if you like, to save wear on your fingertip.


It's best to keep track on paper, so you don't miss one or do one twice. The order does not matter.


Your total efficiency will have to be greater than one to have extra energy to move the car,
one to keep the unloaded cycle going.



I'm even giving you the battery's initial charge for 'free' to make your first hydrogen.

I've been checking out the energy involved in the electrolysis of water, not that it lends much to the argument. However, since I spent the time, I'll share my findings here! 😎

237 kJ of electrical energy releases 2 g of hydrogen and 16 g of oxygen.


I remember from chemistry studies in the 60s:
H2 + 1/2 O2 ----> H2O + 68 kilo calories.

Nowdays, from internet one can find 285.2 kJ/mole. (/mole means we are dealing with 2g of hydrogen, 16g of oxygen ).

These two figures agree because 1 Calorie is equivalent to 4.18 Joule.

From Galu's figure ( 237kJ), electrolysis needs less energy ( 285kJ ) than we get while recombinig gazes to water.

Hence we are on the way to save the planet with an engine creating energy from nowhere.
On the way to share a Nobel price.

New puzzle
: What is going on, in here ??? What's wrong with thermodynamics laws ?
 
Anything is better than pumping 40 gigatons of CO2 into the atmosphere every year.

Unfortunately, to get around this little inconvenience we are going to have learn to deal with uncooperative things like hydrogen and nuclear fuels. Wind turbines are nice, so long as they are out to sea and over the horizon where we cant see or hear them.

Pity the Severn Estuary scheme was scrapped - apparently that had the potential to supply up to 10% of the UK's electricity. However, the plummeting cost of wind and solar probably killed it off.

And if it would be the noise only... Have a friend working for a govt. agency regulating, among others, wind turbines. The bottom line, such turbines (other than exhibition demos, of course) could be installed only north of the polar circle, or out in the ocean. Otherwise, any soil under a wind turbine farm transforms, over the years, in a desert. Even grass and weeds will stop growing under. The impact on the ecosystem is huge.
 
Tidal energy is the best renewable - it's always there, 24/7 and not weather dependant like solar and wind. Of course, it needed some investment to do, unlike easy to implement solar and wind, so it never gets done.
It got done in France, in Normandy over the estuary of La Rance.

( Use, the Wikipedia english version, when I do, the link doesn't work correctly.).
At that time there has been projects for more, but abandoned.
