[ausev] Some familiar units to describe the HHO generator

[John Penry at TransTexasTrucks]

I got so tired of the ads, emails, and now the TV stories, so I made a web 
page, and I am challenging all makers of this crap to prove it works. There 
is a guy in New Zealand offering one million dollars, but it would take six 
months to prove.  Steve Gehrlein could make 10 million bucks selling the 
10,000 orders he has at $1000 each.

I vote for a massive campaign to get Google Adsense to stop allowing this 
type of hype advertising, but then we all know that money talks, and truth 
and honesty have gone on vacation.

One of the local stations has contacted me, but I declined an on-camera 
interview.

Although this is starting to get slightly off topic, since the on board
hydrogen generation craze seems to start happening and is in competition
with the adoption of electric vehicles (not counting Fuel Cell Vehicles of
course), anyone have any ideas on these guys?

I believe the guys at http://www.ronnmotors.com/ are using the system.

The burning of Hydrogen produces 286 kJ/mol...
http://en.wikipedia.org/wiki/Hydrogen#Combustion
Gasoline has an energy content of 44.4 MJ/kg...
http://en.wikipedia.org/wiki/Gasoline#Energy_content
A mole of hydrogen weighs only 2 grams...
http://en.wikipedia.org/wiki/Mole_%28unit%29
Thus a kg of hydrogen has an energy content of 143 MJ/kg compared to
gasoline's 44.4 MJ/kg.

A gallon of water electrolyzed produces 0.40kg of hydrogen for 57MJ of
energy content.  One pint of gasoline is 473cm^3, and the density of
gasoline is around 0.74 g/cm^3.  So... a pint of gasoline weighs
0.35kg for 15.5MJ of energy content.

So, you are correct that a gallon of water takes can produce more
miles driven than a pint of gasoline.

Granted, it would take 140MJ of energy to electrolyze the gallon of
water at 100°C (for 0.4kg of Hydrogen)...
http://en.wikipedia.org/wiki/High-temperature_electrolysis



Or, stated another way, it would take 1.1 gallons of gasoline to give
you the energy to electrolyze one gallon of water which would produce
enough hydrogen to deliver the same energy content as 0.45 gallons of
gasoline.

Hence, you are better off burning the gasoline to power your car than
to bother with any sort of intermittent step involving hydrogen or
water.
