Run your car on water and other fuel-saving scams.
I get quite a few e mails of other stupidity masquerading as fuel-saving devices, and at the top of the list is our perennial favourite, hydrogen from water.
There is extensive advertising on the internet at the moment of a device which purports to save 50% on running costs by getting hydrogen out of water to use for the motor. This isn't just stupid, it's monumentally stupid. This stuff is not worth attacking in its own right. To be dumb enough to think that a device with an intrinsic value of over a trillion US Dollars a year is going to be sold to you on the internet for $99-95 you really ought not to have a driving licence, let alone a credit card.
Beware of this outfit - they have many different websites under a huge variety of names, but they all lead to one thing only, a site with credit card facilities to rip you off. You'll recognise the name "Run your car on water" on the main site.

I was told of another doozy just yesterday - a spark plug which energises the petrol with ultrasound before firing! Known as the "Sonic Spark Plug", this is just another bad joke designed purely to take money off you for no good reason.
I extend my offer free testing to each device which appears on these pages, so do keep them coming!
