You still need fuel to run the engine and the GEN , so to me this is nothing special.

FWIW at a 100% efficiency (not likely) there is only 1367 Watts/sq meter of solar energy. That does set a limit. Typical current technology say 10-14% efficiency but 40% has been done in the lab. The question then becomes whether or not one has enough roof space to handle the panels.

FWIW2 do not mix Lithium Polymer (LiPo) and Lithium Ion batteries that burned up a few laptop computers with Lithium Iron (LiFe). LiFe don't burn well. The other two do. Shorting any of them can produce significant heat in the shorting connection. So can lead batteries.

Back to the OP's question: yes, no doubt at all. As some mentioned, the time factor may make it a moot point, but it will happen.


Some factors that have mentioned are, better batteries, better inverters, better solar panel, better air conditioners, and better conservation. All of these WILL happen, we just don't know how soon, but not as long as some have suggested; it's all getting better now.


Consider that if you use flexible solar panels, they can roll up on your awnings, and you can have more and bigger awnings. You could easily triple your solar collection that way.


If the problem is the noisy generator, consider making advances in thermocouple technology. You need a fuel source, but it is quiet.


Fuel cells are another future that is already here. They are available and they work really well. They are expensive, but they will be commonplace fairly soon, and the price is coming down.


All this stuff is going on now, and we will see more and more of it edging into our daily lives.


For now, relax and turn up the TV, have a cold beer.

The first stumbling block is yourselves - needing to run three airconditioners, domestic fridge, coffee machine, icemaker and dishwasher. Get a lot more realistic as to what you need rather than insisting on what you want and it is quite easy to build a moderately-sized RV that can exist off-grid and without generator almost indefinitely. My OKA is one such vehicle and a friends OKA is another. No fixed shore power wiring system at all. Another friend has just returned from a round trip Australia to Europe and Morocco and back and he hasn't got a shore power connection either.
And no, I don't live in the dark either. Microwave, electric kettle, breadmaker and electric refrigeration plus satellite TV and internet and electric blankets and plenty of power for computers. Diesel cooktop and diesel HWS and hydronic heating.

No airconditioner but we have a new-fangled solution for that - an engine and four wheels to take us where we don't need airconditioning.

BTW Earth roamer have a small airconditioner and if you add a few extra batteries then you can run the aircon for a few hours. Big deal because then you have to idle the engine to keep doing it so you have a big inefficient generator instead of a small efficient one. Then if the next day is pouring rain you need to either travel or idle the engine just to have any power at all. And they have a built-in battery charger as well so they are not as carefree as the advertising blurb suggests.

I am not familiar, with what you refer to a OKA? Will you explain?

Oka was a manufacturer of 4x4 off road vehicles in Australia which were used as utility vehicles, fire fighting and some have been converted as campers.


Please use the quotes when you reply, it makes it easier to follow.

Getting back to question asked about the future. Something will replace generators. Will it be solar? Will it be fuel cells? Will it be a Mr. fusion? Who knows but something will!
