Don't Go Without Your Modern Cons On Your Next Camping Trip - Take A Portable Generator
The benefits of owning portable generators for your camping trips are obvious. You don't need to go without all the mod cons for starters. Some people believe that camping is equal to roughing it but a growing number are starting to realize that it doesn't have to be this way. Portable whisper quiet generators are useful for both tent camping and caravan or RV camping. Your particular need for a portable generator will determine the type of model that you choose.
When you are choosing a portable generator you first need to determine your power requirements. This is just very basic maths. Most devices will list their requirements in watts so just add these up for all the appliances you will have powered at the same time and you will have your approximate power requirements. Some don't have wattage requirements on them but they are easy to work out if you know the amps and volts. Watts=Amps x Volts and you will arrive at the wattage needed to power the device.
Another important often overlooked requirement is the start up current required. If you have large appliances such as air conditioners, refrigerators and or freezers in your arsenal of travel gear then you need to factor in the start up current for your total power requirements. For example, a fridge will require up to 3 times the amount of operating current to start up. Forgetting this important factor could damage your appliances and fry a few electronics. You don't have to add the starting currents all together. Just the ones that you know will be starting at the same time will give you your maximum power requirements.
Fuel Choices For Portable Generators
For camping trips gasoline powered is a good choice but gasoline has a short shelf life. If you need to store a fuel supply for emergencies then most suppliers will recommend a propane powered generator. Some generators are dual or even tri-fuel capable so if you like to have choices you should seriously consider getting one of those models.
Other Things To Consider For Portable Generators
If you are using your generator primarily for camping then the sound rating will be high on your list of requirements. There are quite a few campsites that don't allow generators but you don't want to abuse the privilege when staying at one that does. Most campers are there for the peace and quiet so keep your generator use to a minimum and never at night. These days there are many models that are available that are super quiet but the important thing to remember when it comes to portable generators is that you get what you pay for so plan to pay a little extra for quality and durability. If you camp in national forests you will need to get a generator that has an approved spark plug arrestor. It doesn't hurt to be on the safe side when it comes to preventing forest fires.

air Oil Extractor i tried to make a supercritical fluid extractor, but why didn't it work? here is what i did:?
i used a 20 oz co2 tank filled with a 1/2 pound of dry, ground lavender and 1/2 pound co2. in line was a porous metal filter, the a regualor then a valve. at room temp, the pressure was 550 psi so i heated the cylander until it reached 1300 psi and then opened the valve into a glass jar. out came only gas, into the jar and then into the air. The gas was especailly fragrent but there was no essencial oil. why? Did the oil get carried away in the gas? Was there no fluid to carry the oil? i know that the industrial method is to first soak the plant mater in a liquid solvient, separate it, and then extract from the solvient. or is there some other reason i'm missing?
a good organic solvent to use is plain old rubbing alcohol (less dangerous as well). Just let it soak for 3 or so days in it and that can isolate the essence.

A steel storage tank for propane gas is in the shape of a right cicular cylinder of altitude 10ft with a hemishphere attached to each end. Express the volume V(in ft3) of the tank as a function of r (in feeet)
v = v(cylinder) + v(sphere) ... where the radius of cylinder and sphere are equal
V = π r^2 h + 4/3 π r^3 . . . given h = 10 V = 10 π r^2 + 4/3 π r^3 or V = 2/3 π r^2 (2r + 15)
