We sell generators at
www.EmergencyPower.com I had to jump in here not for a plug but because I feel we have some knowledge in this area and people are making huge mistakes by running a generator indoors or too close to your home.
Being in the industry we hear all the news on this. CO2 will kill you. You will not smell it, you will not see it and you will not know there is a problem. It can build up in your garage and you can walk in and be overcome by it and pass out. Many people die from CO2 and it simply is not worth it.
A co2 detector may help but do you want to trust your life with it?
Buy a diesel not gas. It creates less harmful emissions then a gas generator. You can make your own fuel and it is a lot safer then having days of gas stored at your home.
Diesel is heavy and if someone can lift it, they can have it. Good luck to them.
Secure it by a chain, wrap it around your car tire or drive over the end of it. You don't even need a lock.
We post many stories about people dying from co2 during power failures on iGeneratePower.com It is amazing how many die from running them indoors or too close to the home. I have no idea what they where thinking.
