A low tech and natural air conditioning system

I like Treehugger for coming up with great designs that could change a bit the world we are living in. One of their latest finds was a natural air conditioner that uses clay and evaporation. As Treehugger noted : ”  Thibault Faverie‘s Cold Pot is a natural and simple air conditioner that uses clay and …

Stunner : carbon dioxide role known as early as 1932

While vested interests are still denying the warming role in our atmosphere of carbon dioxide, TreeHugger has unearthed a study from early as 1932 showing that this gas is actually warming our Planet. This was 81 years ago ! I had heard or rather read that this was known from at least since the 1980s …

Here come the toilets of the future

Here is a smelly question : why are we putting together what Nature separates ? This is the question asked by a Swedish researcher about toilets. Putting urine and feces together is not a good idea as it is simply a waste of resources. Moreover, flushing with liters and liters of perfectly drinkable water is …

Engineers discover self healing circuits

To Ecogeek : “ A team of engineers at the University of Illinois have figured out how to create self-healing circuits in electronics and batteries, a discovery that could lead to longer equipment life ” ” As electronics have become more complex, one small circuit failure can render a device useless, especially since it is hard or often impossible to …

Climate change and extreme weather are linked

I have previously written that the link between extreme weather events and climate change wasn’t clear. It isn’t the case anymore as the latest research from the IPCC proves. As Cleantechies notes : ” A new report says that an increase in heat waves is “virtually certain” as a result of global warming and that …

A real must-see and must-share video on climate

While reading Climate Progress I came across a must-see speech from Senator Sheldon Whitehouse, from Rhode Island. As the description on Youtube notes : ” There are some laws that Congress can change. The laws of nature aren’t among them. While lobbyists continue to call for more and more “second” opinions, Sheldon points out to …

D-Light, data through illumination

To GOOD : ” One German physicist, Harald Haas, has come up with a solution he calls “data through illumination” (…) by sending data through an LED lightbulb that varies in intensity faster than the human eye can follow.” ” It’s the same idea behind infrared remote controls, but far more powerful. Haas says his …

Will molybdenite be better than graphene ?

As CleanTechnica recently noted : ” A serious challenger has emerged to take on graphene’s title as the miracle material of the 21st century, and that is a common, silvery looking mineral called molybdenite. (…) The lead researcher asserts that compared to conventional silicon transistors, a molybdenite transistor would use about 100,000 times less energy …

Battery breakthroughs for electric vehicles

Many are working on extending the range of electric cars. Here are three of them. Firstly TreeHugger believes that replacing the  graphite electrodes in lithium-ion batteries with silicon nanotube electrodes,would multiply the range by ten. ArsTechnica notes that carbon nanotubes in ultracapacitors ” may make sense in electric cars, even if it can’t store as …

Help in finding new solar technologies

If you let your computer idle while you are away or asleep, you might consider to allow Harvard and IBM to use it to do calculations for the Clean Energy Project, which is part of the World Community Grid. Due to find new ways to create more efficient solar photovoltaïc panels and later of batteries, …
