Alternative Energy

A friend of mine in NL design in the back of his car a
plug-in system for charging an extra battery.Each day he drives
total about 40km to his work,so total 80km.

When he comes home he plugs the battery into his own made power
generator including 220v inverter where some lamps and also tv are connected.
Lamps:1 toilet,2 bedrooms,2 in living room and the hall. According to him total
5-6 hours he can use this if all connected items are fully used,but he
normally spends more time in his living room and uses only two lamps, tv or
tv stereo.

So,because he has to drive daily minimum 80km he generates some free electricity.

Im wondering why the car industry don't design this system standard in
all cars. Free extra energy/electricity for other (small)purposes without
using solar.

Still costs to make solar components ......remember to include "dust to dust" component.

If you refer to my above example: you dont need solar.
While riding a car an extra battery will be charged.

Well as someone previously put it, energy cannot be created or destroyed, just changed from one form to another. (basic physics)
If your friend is getting his battery charged from the electrical system in the car, or from some mechanical attachment to the engine or chassis, then the energy to charge the battery is coming from the fuel in the tank.

Not very efficiently either i might add, simply because the conversion in a petrol (or diesel) engine is of low efficiency.
A lot of energy lost in heat etc.

If he was to use the battery generator as a braking medium, then he would be improving efficiency by storing some of the lost energy, however, it is still at a low efficiency again because of the heat losses etc.

So, not for free I am afraid. Better if he used a wall socket.

Then again, if he uses his battery to drive an inverter to get 240v ac or similar to drive his end product lights etc, then he is facing more losses.

Ask some Thais why they drive at night with their car lights turned off and they will tell you "to save petrol".
Many will laugh at first but it is actually true. Not very much saving and the repercussions are disasterous but the fact is less energy being used.

If charging extra battery from the electrical system in the car while driving needs extra fuel then you are right. Im not a technician but I doubt this. Perhaps he did like this but his system is more sofisticated system.
He designed a plug-in-system.

Doesn't matter whether it is "plug-in" or "screw-in" or whatever, or how many videos you come up with.

You said it was "free energy" which it simply is not.

I'd suggest you go read a physics book before one of these characters with their "free energy" theories makes a big hole in your investment bankbook.

Maybe you are right.

Stand alone solar system is thus also not free. you have to make an investment and for example in
Thailand, where in the villages most of the thai houses dont use a lot units and thus the electric
bill is 0, a solar system is not profitable in such cases.

Do not forget, its also handy to have such a system in case electric falls out, especially when you already
connects some lamps to inverter/battery

I just looked at this vid. Someone runs nearly everything he needs for his house incl. the use of a microwave on
solar for a total investment of only 1200-1300usd. Just want to share this vid with you.

Really briefly, here is how it works:

Electrolysis breaks the bonds between hydrogen and oxygen in water. This process is less than 100% efficient.
The hydrogen in burned in your engine (combined with oxygen from the air) to power your car. Very inefficient.

This is not an efficient use of energy, but it is one way to effectively make your gas powered car run from electricity. As far as I know, nobody has published cost figures -I doubt it competes with LPG since the main theme of the promotional material does not focus on the cost per km, but rather on the sensational concept of "Running your car on water!"

By the way, Solar is off-topic, but it is a valid power source that I believe in. In some cases, the economics work out.

West of Khon Kaen about 1.5hour drive to Chum Phae and then about 10klm on the northern road to Si Chom Phu, Si Bunreung, back highway to UdonThani there is, what appears to be, a new solar installation.

No other info around, did a google search but found nothing about it, re-size etc. but area about 50-60 acres at a blind guess.
