Deterrent

The 'head' of the WatchStander system, incorporating a video camera and a 12 million candl...

Today's ships are equipped with radar systems that let them identify other ships from a distance, and while that works well enough for collision avoidance, those systems aren't the greatest at detecting small watercraft ... such as the low-slung skiffs often used by pirates. That's where WatchStander comes in. It's a radar system that's designed to pick out such boats, and then deter their crews before they can attack.  Read More

The Kite Mosquito Patch is worn on the clothing like a decal, and is said to keep mosquito...

Depending on what part of the world you live in, mosquitoes can range from being an annoyance, to acting as carriers of life-threatening diseases such as malaria and West Nile virus. Sprays containing deet do a fairly decent job of keeping the mozzies at bay, but they’re also highly toxic. Less-nasty sprays, bracelets and other devices are also available, although (as I can attest to from personal experience) they tend not to be very effective. Now, however, a group of California-based entrepreneurs are developing what could be the ultimate deterrent – the Kite Mosquito Patch.  Read More

The B.O.N.D. Bike

The Environmental Transport Association (ETA), a British company that offers bicycle insurance, recently surveyed 800 cyclists to find out what aspects of cycling they liked the least. The primary purpose of the survey was no doubt something boring and insurancey, but one of the spin-offs is kind of fun – the company put together a one-off bike concept that addresses four of those dislikes in a rather extreme fashion. It’s the B.O.N.D. (Built of Notorious Deterrents) Bike, and it’s almost certainly the only bike in the world with a flamethrower built into its handlebars.  Read More

Barnacles are a major cause of fouling of ship hulls (Image: NOAA)

Fouling of hulls is a major problem for world shipping – for private leisure craft as well as large cargo ships – with barnacles being a major culprit. It reduces the performance of vessels and increases their fuel requirements. Medetomidine has proved effective in preventing fouling of ship bottoms and now researchers attempting to develop new, environmentally friendly methods to limit marine fouling have identified the gene that causes barnacles to react to the substance, opening up the possibility of an antifouling paint that is gentle to both barnacles and the environment.  Read More

Drink No More will sound an alarm and flash a warning signal when your pet approaches the ...

Household pets like to drink water from the toilet because it is cool and readily available. However, it's also full of bacteria and toilet cleaner residue, both of which can make your pet ill. And you don’t really want them near your face when you know where their head has just been! Drink No More is an alarm that is on alert when the toilet lid is up and sounds warning beeps when a pet or person approaches the bowl.  Read More
