400 liters, the trunk of a C3 or Megane.

400 kg more, it is also (and especially) a much higher consumption at each acceleration (so after every red light, roundabout ...)

In relief of cars calculations, considering that 30 kg less is the 0,1 / 100 consumption and less.

400 kg more, so this is the 1,3 / 100 more ... and a proportional brake wear, suspensions, tires ....

In the most common case for commuting - work, it will only work for the return trip, the water heated during outward having time to cool down during the workday.

When the solution to discharge water on each trip, that's for regions that do not lack water : Mrgreen:

I agree with you, Lilian, The fact that the lost energy is considerable (or exergy used to be very modest!), But its recovery seems problematic.
Increased weight is far from negligible consumption perspective: the increase in mass increases the inertia at each change of pace (slowing this energy to supply more is lost during braking, as often in descents).

One can warm his lunch box and find a system to baths for feet comfortable temperature when it is rolled
(Boots 7 special leagues for the driver) Image it might be nice hot tea dispenser : Cheesy:

For socks, would remove them and Mrs. could do a little laundry in the back, with a reduction gear on the drive shaft to rotate the bottom of the washing machine. It would be benef ...
(Thin one will call me sexist) : Mrgreen:

===============
Suppose that with this temperature available in 80 330 ° C liters we should keep 60 ° C water heating system of a house isolated 150m2. How long it will last, with a ladle?
We would therefore have a ∆º of 20 ° C
4186 X 330l Joules / kg X = 20 ° 27'627'600 Joules
27'627'600 Joules / 5'000 (P W) = 5'525 seconds or 1 p.m.

(It will have to in him tons and tons of clay to store summer heat for Lilian, and storage area well contained and well insulated in depth ... if he wants to warm winter with) ^^
===============
PS: apart from that we could store the heat in molten sodium, but it is not hot enough, take at least 200 ° C ...? And sodium, would have to carry the load all the way. I see no solution. Walk, it warms!

I think it is playable for ECS (150 liter tank). But it is true that the more disadvantageous is that the path of the job, there is the return path which is profitable ... the ride will go was less profitable .... and then there all what is not seen in the implementation in the end ... can be playable on a utility and a suitable configuration calories discharge.
Heating unload power 5000w during 1h30 not negligible understood that energy is lost.

My grandfather had patented a similar system in 30 years, it was quick connectors to plug the cooling system of the car on the central heating of the house.
But the concerns were not the same at the time, it was to avoid draining the radiator of the car every evening in winter ...
He said jokingly that outsmarted had invented him antifreeze.

To recover energy wasted by the engine, because the water is too heavy, it could melt salts with the exhaust, at a higher temperature?

With hydraulic quick connections and a small modification in the garage or at the point where we place the car. this kind of trick even if it seems far-fetched is not so meaningless ... because 95% of daily trips wastes at least 2 times that amount of energy and 80% of journeys merges with empty passenger vehicles .
After you have to have vehicles .... not too recent and rather type utility.

Hello,

indeed interesting idea. To decrease the volume shipped, why not turn to the phase change materials with unfortunately complexity of the installation. There are several discussions on this type of material on the site. dede2002 has almost talked with soluble salts.

Sorry Cortejuan, but already answered well in this post >>> it would take at least a temperature of 200 ° C for it to be meaningful.

And already also answered, not interesting because it would then have to lug sodium throughout the course!

En strong heating gypsum 150 200 ° C to ° C, in the car we'll plaster free walls, with this heat recovered!

Same for making cement, but close to 1000 ° C in the pistons !!

This is how I see the system

The ideal would be to adapt the idea in many places.
Like that wherever we go we can give the stored calories.
Global Warming you said ^^
