Okay, so this isn’t strictly about architecture, but it is about something you personally can do to produce less pollution and lessen our dependence on oil.

I don’t know about your city, but here in Los Angeles, even The Cheap Gas is now $4 a gallon.

It cost me over $41 this evening to fill up my little Saturn. I used to be able to fill it up for just $20!

(I actually drove it until the “low fuel” light came on. I have been praying for the past week that gas prices would become a little less rapacious before I became absolutely desperate.)

I found this amazing set of instructions that outlines for you exactly how to make a device that will DOUBLE your gas mileage.

This device uses inexpensive items that you can find at a hardware store.

Learn how you can do this.

This one system is really five hydrogen systems:

1. HHO/BROWN’S GAS GENERATOR (people call it “Hydrogen Generator” but as I said HHO is more powerful than pure Hydrogen), consisting of the Electrolyzer, wiring harness, hoses and installation accessories. Works with Pure Baking Soda in distilled water. Will boost performance in most cars, pickup trucks and big-rigs (large semi trucks). So far has boosted MPG by as much as 185% on a Chevy 4WD truck with Water4Gas, but more realistically you should expect 20%-50% better mileage.

Learn how you can do this.

2. WATER VAPOR BOOSTING SYSTEM, consisting of the Vaporizer, hoses and installation accessories. Works with tap water. Not as powerful as system #1 but can still boost your car’s power and mileage by 10%-15%. Very simple, easy to replicate in 5 minutes.

Learn how you can do this.

3. CHARGED WATER SYSTEM, a unique invention making use of BOTH JARS with distilled water, Pure Baking Soda as well as tap water and hydrogen peroxide (cheap non-hazardous liquid from your drugstore or dollar store). Instructions will be given to you, and you will find this system very interesting. You will need a small aquarium pump and a cellphone charger. This revolutionary use of simple everyday hardware has made cars in Florida, Montana and California improve fuel economy by 40%-50%.

Learn how you can do this.

4. ADVANCED HHO BOOSTING SYSTEM. This system is the best of the best and consists of the Electrolyzer (with the wiring harness, hoses and installation accessories), enhanced by the PCV Enhancer, Fuel Heater and above all MAP Sensor Enhancer or Electronic Fuel Injection Enhancer. Works with Pure Baking Soda in distilled water. Works best in newer cars (1996 and newer). So far has boosted MPG by 107% (double mileage).

Learn how you can do this.

5. HEALTHY DRINKING WATER MAKER, a unique use of BOTH JARS with distilled water, Pure Baking Soda as well as filtered water (no hydrogen peroxide this time). Here too you will need a small aquarium pump and a cellphone charger. UNIQUE system that you cannot find anywhere else - rivals drinking water chargers costing $2,500-$6,000, yet you will learn to make it for $20-$50.

You could do this over the weekend. Seriously.
