Free File Shredder

Wednesday, July 30th, 2008

One of the things I noticed when I started playing with the Partition Recovery program I reviewed below was that such image backup and recovery is at the lowest possible byte level across the entire drive. When I recovered the image, it recovered all possible files that could have existed on that image including files that I had previously deleted and even after formatting the drive over top of those deleted files several times these files still appeared to exist after a full recovery of the drive image.

I quickly discovered the need for a file shredder. This is a software package that will write random data over the blank sections of your hard drive. You see when you delete a file in Windows is simply marks the file as deleted in the file system table. So the file data is still there but the pointer to that file no-longer exists. Thus Windows thinks the file is deleted. A file recovery program will search those sections of your hard drive and give you the opportunity to recover files that do not have any pointers to them but as long as the file still exists on the drive and has not been written over then these recovery tools can recover the data in that file.

This can be a security issue, because if that file data is still physically on the drive then there are other programs that could gain access to it, such as a worm or virus. Thus data that you intended to delete is now suspect to recovery from nefarious software that could be on your system.

A file shredder will of course, as I’ve described write random data over these empty sections of the drive that don’t have active pointers pointing to those areas. Basically it’s writing data over all the areas of your drive that may or may not have either blank data or data which you have previously deleted. It also means that recovery from a drive where the empty space as been shredded will not have any chance of resurecting any files from previous installs, or worse bringing to life a virus that was previously removed.

Do you ever have those one of those annoying days when you suddenly find out your system is infected with a virus?

Comment on “The Hydrogen Hoax” - by Dr. Robert Zubrin

For those of you who don’t know who the heck Dr. Robert Zubrin is you need to have a look at the Wiki on him:

Another good HHO site with good info!

I just ran into another blogger online with some good information on the real science of Hydrogen gas and cars.

Missunderstandings on HHO Energy - Part 2

Thursday, July 17th, 2008

Well I said I had more to say about HHO and so here it is.

First, HHO is most definately not Ho Ho Ohh. I nearly blew out my ears last weekend! If your going to work with Hydrogen gas then read my post on Detonation Velocity and know that it is a VERY explosive gas. It diffuses quickly but it can pool in your ceiling and form a flamable inverted lake of on the

Missunderstandings on HHO Energy - Part 1

Monday, July 14th, 2008

Well I just finished building my first Water4Gas HHO system. I tested it with pure water first, then tried to add a single teaspoon of baking soda. Once I started to get bubbles they came at a moderately fast rate from the single jar electrolyzer. The gas production was a little more then I expected but it’s not as much as I am hoping to get, also I was running a lot more power then I thought I would need. It’s possible that additional baking soda could yield more gas for less power, however I’m pretty sure that this is not the optimizational pathway that I want to take.

HHO Detonation Velocity

Tuesday, July 8th, 2008

Some of you are probably already thinking to yourselfs, “How does this guy know so much about HHO?” or “Who does he think he is?” or “What is this guy coming from?”, etc…

Well to answer a few of those questions, I don’t know a lot about HHO, or Browns Gas, or Hydroxy gas or whatever it is you want to call it.

The fact is I payed attention in school, even if I didn’t get the best of grades I still payed attention, and I read the books. Maybe I didn’t get all the problems right but I got the concepts and the theory down pat. So now when I hear about something and I want to learn more I do this thing called “Research”. It’s where you go online or to the local library and you look for some real science on the subject. I don’t trust sources that are not verifiable so I search for material that I can trust and corborate from other trusted sources. That means finding multiple sources with the same or similar data and information or test results.

So I only heard about HHO a few weeks before I made my first post here on my blog about it, but a perfect example of what I did to research is when I heard in a YouTube video that the detonation velocity of Hydrogen gas is 40,000 ft/sec. I said to myself, “That really doesn’t sound right at all and I bet that number is wrong!”

Here is the YouTube Video that claims detonation velocity of Hydrogen is 40,000 ft/sec:

Just because these guys got the detonation velocity of Hydrogen doesn’t mean the rest of what they have covered is incorrect. Rather to the contrary most of what they have said is correct. In fact almost every thing they have said is correct. The only other thing they didn’t cover is the ideal gas law and basics of thermodynamics (Although they briefly touched on it). I’ll give you a hint, if you don’t know what that is you can find some good wiki’s on these subjects. Also plenty of university websites with free information on these subjects. Failing that, you can always look in your kids Chemistry book. Incidently the entire series of videos made by these guys is really good and does cover a lot of good material! Appart from the wrong number of detonation velocity of Hydrogen.

More on detonation velocity. I did some research and found out a whole lot more about detonation velocity. First off, this is actually a measurement used in the field of demolitions. The detonation velocity is used to tell explosives experts how much rock or stone or building foundation a certain volume of explosives will move upon detonation. It’s not a direct measurement but there is a corelation that explosives experts will use when planning and setting up for their demolition event.

So I discovered that the detonation velocity of TNT is about 7000 meters/sec, do that math and that equals about 22,965 ft/sec.

I doubt very much that Hydrogen will burn faster then TNT!

On that note, C4 burns at a rate of 8,340 meters/sec = about 22,965 ft/sec.

Pentane detonation velocity is 1,680 meters/sec = 5,511 ft/sec.

HHO, to scam or not to scam

Thursday, July 3rd, 2008

There are a lot of people claiming that HHO is a complete scam, and there are a lot of people who claim to give mathmatical evidence as to why it cannot work, and they usually go on about how you can’t get something for nothing, how nothing is free and no such thing as a free lunch. On and on they go!

On the other hand there are a lot of people who claim it has worked for them and that
