Microwave Cloaking Device

Scientists at Duke University in North Carolina have just unveiled the worlds first real cloaking device. Right now the cloak only works with microwave light, but will actually distort the light around the object to be cloaked, that when the cloaking device is turned on the object would almost completely disappear. Ulf Leonhardt is a physicist at the University of St Andrews in Scotland and had the following to say about the project:

“It’s not perfect … If you could see in the microwave region of the spectrum, the copper ring would not quite disappear. You’d see perhaps a shadow and some slight distortion where the copper ring ought to be.”

The device makes use of “metamaterials”, created by the scientists on the nanometer scale, which exhibit peculiar electromagnetic properties not normally found in nature.

Glow In The Dark Pebbles

Glow In The Dark Pebbles

These glow in the dark pebbles would actually be a really useful addition to a sidewalk or garden path, outside the house I hope to one day buy. They look fairly unremarkable during the day, but at night would glow for up to six hours after the sun goes down, allowing those late night parties to continue without having to worry that someone might wander off the path into the roses. You can buy them here at Collections Etc. for $9.99 / container of 350 glow in the dark pebbles.

A Missionary on the Internet

I thought it might be appropriate to write a more personal entry and give you a little bit of background on me as the author of this blog. So, allow me to tell you a little about who I am and what I do. My name is James, and at my real job (ie not posting stuff here) I work at Campus Crusade for Christ as a missionary on the internet. I am a Christian, and that means I believe “Christ” is more than just a swear word. It means that I believe God sent His only Son, Jesus Christ, to die here on earth in my place, paying the ultimate price for MY sins so that I don’t have to.

In light of the sacrifice that He made for me, I want to tell others that they too can have the same opportunity to have LIFE. People don’t have to pay for their sins, if they don’t want to. God already paid the price, and all we have to do is accept His free gift of salvation and believe in Him. Most people think that if they work hard enough, or do enough good stuff to outweigh the bad, they’ll get to heaven. Unfortunately, that isn’t true. God says that the punishment for ALL sin, no matter how small, is death. No other options, that’s just the way it is. In light of that and because of His love for us, He sent His Son to die in our place. Now all we have to do is accept that gift.

The problem is, most people don’t know that the opportunity is there. They are still trying to do it on their own, and they’re not going to make it. It breaks my heart when I see people trying so hard to do the right things, or searching for answers in all the wrong places, when the answer that they are searching for is right here in plain view. Salvation from sin, freedom from judgment, and purpose for life are all right here. We just have to accept them.

Yet so many people ignore this gift. So many people turn it down, choosing to try and get to heaven on their own. It’s like being offered the keys to a mansion, and turning them down, choosing instead to keep living in a cardboard box on the street.

So that’s a little about me, and what I’m passionate about. I’d love to hear any thoughts you have on this.

Do you enjoy barbecuing? Check out The Original WienerStick. Recently invented by a Canadian inventor near Vancouver, the Original WienerStick is designed to make the task of barbecuing hotdogs, wieners and even chicken much easier. Food cooked on the WienerStick does not require turning or constant supervision as hotdogs on the grill might. Rather the food is cooked vertically on stainless steel skewers, and heat from the base is transferred straight up the tines, resulting in food cooked from both the inside and out at the same time.

A great great Christmas or birthday gift idea, the WienerStick can even be used in a conventional oven to cook things like corn-on-the-cob, or simply for when weather prevents barbecuing. It is dishwasher safe, built with stainless steel so it won’t rust or break, and single piece construction means it has no small parts able to get lost or broken. It also comes with a 30 day full money back guarantee so if you don’t like it you can send it back for a full refund.

Food able to be cooked on the WienerStick includes:

  • Hotdogs
  • Wieners
  • Smokies
  • Chicken
  • Fish
  • Corn on the cob
  • Roasts (using 2 in tandem)
  • Vegetables
  • Baked potatoes
  • Experiment with your own!

The WienerStick Barbecue Accessory is available from http://www.wienerstick.com for $19.95 Canadian (est. $18 USD). Check it out, and tell us what you think!

Flying Superman by Remote Control

Radio Control Flying Superman

If you enjoyed the superman movies, you’re really going to get a kick out of this remote control flying superman. I happen to be an RC flying hobbiest myself, so having a flying remote control superman sounds pretty good to me. Too bad I’m broke… but if I wasn’t, I’d buy it at amazon. Requires eight AA batteries which are used to charge Superman’s internal battery in about 10 minutes.

Rocket Bicycle Powered by Tar

Rocket Bicycle

This rocket powered bicycle reminds me of something “Tim the Tool Man” might build. The rocket bike is powered by a 200-pound-thrust rocket engine that uses roofing tar as the propellant, and a model rocket motor as the igniter. Capable of doing 0 to 60 mph in 5 seconds and up to 147 miles per hour, the rocket bike is fast enough to beat a Porche in a drag race… if you can manage to hold on.

The following is a video clip of the bike in action.

H-Racer Hydrogen Fuel Cell Car

H-Racer Hydrogen Powered Fuel Cell Car

Want to teach your kids about the value of Fuel Cell technology and being environmentally friendly? How about getting them the H-Racer, a toy fuel cell powered race car for Christmas! This fun little toy is powered by a hydrogen fuel cell and will drive for over 100 meters on a single tank. Refueling the vehicle is done by connecting it to the included, solar powered, hydrogen refueling station. The following quote is taken from the H-Racer website:

Cars running on clean and renewable fuel are the dream of many of today’s world leaders, engineers and scientists seeking to eliminate mankind’s reliance on fossil fuels in favor of climate-friendly energy resources.

With new advances in technology, hydrogen is on its way to becoming the world’s next fuel. Hydrogen offers many important advantages: it is non-toxic, renewable, clean to use, and the most abundant element in our universe. And by using fuel cell technology to convert hydrogen to electricity without any combustion, the technology is a significant solution to many of our global energy and environmental problems.

No combustion occurs inside a fuel cell. The only exhaust resulting from hydrogen fuel cell cars is pure water. Fuel cell cars that use hydrogen as a fuel are also known as “zero emission vehicles.” Today, many of the world’s automotive companies including Toyota, GM, Ford, Honda, and Daimler-Chrysler, are developing hydrogen fuel cell vehicles with the hope of introducing this technology to the public in the near future.

Hydroflyer – Is it a boat? Plane? Car?

[kml_flashembed movie=”http://www.youtube.com/v/PIWfvzUT_Z4″ height=”350″ width=”390″ /]

If you’ve ever wanted to get an RC vehicle, but had trouble deciding whether you wanted a car, plane or boat, perhaps this Hydroflyer is just what you’re looking for. Watch the video.

The Hydroflyer can function as a boat, can take off to become a “plane” or just skid along the ground like a car. (probably not good for the paint) From the video it appears to be pretty maneuverable and robust. Can be bought here. On the other hand, if you’re good with modeling, you could probably make one using these free plans.
