Hydrogen is abundant on this planet as the main component in water. Being able to make use of this element as a power source would lead to truly sustainable and clean energy. The fuel cell of the Hydro-Car allows hydrogen and oxygen to combine, producing electricity and water. This water can then be reused to extract hydrogen and oxygen so the system is one continuous cycle that can be sustained naturally. The Fuel cell is a reversible Polymer Electrolyte Membrane (PEM).

The Hydro-Car uses electrolysis to separate the hydrogen and oxygen out of distilled water (provided by you). It stores this in the tanks located at the back of the car, to then combine the hydrogen and oxygen to power the car. The electrolysis though does require powering, and so the kit includes a solar panel to provide a clean source on energy to provide this. The kit does also come with a battery pack that requires two AA batteries that can be used instead of the solar panel.

Once the car has hydrogen and oxygen stored in its tanks it is ready to go. You can see when the car is running from its own hydrogen as two blue LEDs will light up and flash on top of the motor. The Hydro-Car is able to independently navigate around a room avoiding obstacles in its path, it can reverse until it discovers a clear path to travel along.

The Hydro-Car comes in kit form with detailed instructions. These instructions help to teach you about hydrogen power and its advantages and through making the kit and achieving a working car model you will have gained insight into how a hydrogen fuel cell works. The Hydro-Car makes a great educational toy to show children some of the latest eco-friendly energy ideas while being fun to operate.

Designer Nitipak Samsen has designed the Automated Tree-Rental for Emission Encaging Machine (ATREEM), which essentially allows you to purchase carbon credits from a tree. The gadget measures the growth of a tree, translating into how much carbon dioxide the tree has absorbed. The gadget is designed to highlight just how long it takes for our carbon dioxide emissions to be reabsorbed.

The device is more about awareness than being a practical method for charging people for their carbon dioxide emissions. However, the gadget is capable of charging credit cards using its swipe-card interface. Just to give you an idea about carbon emissions, this is what I discovered on the designer’s ATREEM page:

The user interface of A.T.R.E.E.M. shows the intangible CO2 in term of gram and how long does the tree take to offset that amount. i.e. 10 minutes on tube journey emits about 350 grams of CO2 and the tree takes 2 days 10 hours to offset that amount. This way the user can imagine how good they are at leaving waste to the planet.

As part of the design, Nitipak Samsen created a tape measure that helps children to realise the hard-to-imagine metrics for CO2 emissions into actual tree measurements. I think it’s a fantastic idea, and would love to see it in schools!

The Nature Series USB Flash drive is an attractive USB drive made from PEFC certified (sustainable) natural hardwood. The USB drive is machined from European Maple, and can be made into a number of capacities from 32MB to 8GB. The USB drive and the manufacturer FlashBay are both completely carbon neutral too.

The USB drives measure 58mm x 22mm x 11mm, weigh 11 grams, and are supported on Windows 2000/XP/2003/Vista, Mac OS X and above. The Nature Series USB Flash drive can be branded by either colour printing or laser engraving. This means you can order USB drives branded with your company’s message or logo. You might give them out with presentation material after a converence. If you have an ethical business, a carbon neutral gadget would reinforce that message.

I must say, the Nature Series USB is the nicest looking USB drive I’ve seen in a while, let alone one that’s also an eco-friendly gadget too.
