Use paper plates.

Battery capacity may not so important in this case - especially with 900 watts of solar capacity (yes it is enough). The main reason is because a freezer can be run as an opportunity load. In fact, I recommend placing the freezer on a timer such that it runs only during the day when the panels...

To those who have spent time boondocking - particularly in the western states - are sources of reasonably clean fresh water readily available in the field? It seems straightforward to process such water using a combination of filtration and a heat regenerative pasteurization system powered by...

Batteries need to increase their energy density (by both weight and volume) and especially decrease their cost. There is also improvements with respect to cyclic degradation to consider - which factors into long term cost. Cost is the single most important hurdle to overcome. Of course...

It depends on the specs of the system and driving habits. Of course, a conventional EV driven in a conventional way doesn't stand a chance. But what about a van or trailer driven at 5 mph over a few miles daily? That is a different story altogether. Is this a practical configuration? Answer...

Many thoughtful replies. IMO, I do not see an inherent problem with an electric van or RV. Unfortunately, the technology available today requires that such a vehicle cannot perform as its internal combustion counterpart. The obvious problems include cost and range limitations along with lack in...

Conventional autos already run on fumes. The gasoline is vaporized when mixed with air at the carburetor, intake manifold, and intake. Fuel injectors effectively atomize the fuel for efficient and rapid vaporization during intake. This is a silly idea.

I think this is a good idea assuming the setting you described. Careful about the car you get as those in very hot regions likely have lost more battery capacity. Also, it's a bad idea to charge with a Honda EU2000 as a good conventional Genny would increase efficiency nearly 50%. Yeah, use...

450-500 watts electrical is expected for a 5000 BTU/hr window a/c unit. I suggest double checking your unit.

Double post.

Thanks for sharing the results. What kind of inverter are you using? I have zero doubts about the viability of providing AC with an off grid solar system. It just has to be properly configured and properly operated.

I do not believe this is a practical alternative to using gasoline or diesel - at least not at current prices. However, it can be surprisingly efficient. Proper design is critical. Using charcoal is a not a good idea as so much energy is lost in processing the wood. However, wood can be used...

I've built small rocket stoves and small updraft gasifier stoves. The most effective system is definitely a forced air updraft gasifier stove. It's actually amazing how well they can be made to work. A small 12v fan can be used with a rheostat to control the output. Here is a good product...

Actually, we can't blame the Fed as the federal government in general deserves special recognition. They came up will all sorts of imaginative interventions a la "New Deal" - which, historically speaking, was largely a carry over from during Hoover's administration. However, the consensus among...

I realize this is an old thread. I just wanted to note that I do not consider this idea to be completely without merit. Although, it wins zero points for practicality. To answer the last question, in fact, you would not be the first vandweller to run on wood. I am aware of a group of young men...
