Etching solution is probably more well known as solution containing Iron(III) Chloride. This Iron (III) Chloride is probably very bad for our environment (it is) or toxic plus very acidic. (See Wikipedia here for more info.)
If you have kids in your house and you like to etch your own PCBs, having too much of this toxic, etching solution is probably not a smart idea nor is it great for the environment everytime you wash it down the toilet (or sink).
Now, there’s a better, environment
For those of you living like a scumbag and never recycle, here’s some of the best eco green posts to help you get out of it:
You might remember the “water-powered” batteries from Japan about a year back. Well, if you thought that was innovative, check out Brother’s new invention, vibration-powered double-A batteries that can be used for low-voltage gadgets.
I know for a fact that this would work really well for kid’s toys where shaking often occurs anyways, this could be ground-breaking, saving a whole lot of energy worldwide when it debuts.
This time, Brother Industries prot
These nice young folks in Ecuador have built their own homemade DIY wind turbine, looks awesome and what a great way to create energy!
We wanted to make a wind turbine from easy-to-find materials and using simple tools. The rationale for this is that the generator should be easily reproducible by anyone. This also meant making sure the Ecuadorians could find all the materials locally so they could easily remake it, should they want to (and they should!). Finally, we are not experts and do not have access to a super advanced machine shop, so keeping it simple (stupid) was the
If you’ve worked in a warehouse before (like me), you know how valuable pallets can be. (or maybe the opposite) Pallets are not only great ways to move goods in our world, they contain a lot of wood, meaning they can be recycled into many things like a shoe holder???
Anyways, WebEcoist has a collection of Top 20 uses on how to recycle/re-make pallet boxes,
Minnesota has just started their rebate program for Energy Star complaint appliances to promote energy saving statewide.
This is similar to the PG&G program here in California where I live, PG&E replaced my refrigerator for free with a more energy-efficient one TWICE. Of course, the energy savings over long term could easily pay for the fridge itself plus we are reducing our carbon footprint. It’s good to see that slowly state government is giving out money to promote green energy.
For those of you who have been waiting to get a new appliance, there ne
Skateboards are probably one of the toughest built sports gear out there (and probably the reason why skaters like to throw them up in the air for no reason). Haroshi, a skateboarder and artist in Japan, has devised a way to make some great art using old skateboards. I would have to say these are indeed works of art, definitely check it out here.
“As a skater, I want to take responsibility of reusing skateboards when they were no longer useable,” Haro
As an avid motorcyclist, I don’t really worry about my gas too much as it gets as much as or better than most hybrid cars at 55MPG+, but this inventor decided to make motorcycles even more efficient by focusing on aero-dynamics. Based on his studies, 90% of drag at 55MPH is caused by air, not your wheels. So the above design was born, which gets 214MPG going 55MPH!
Now, I don’t see how I could ride that thing and look cool but I guess the point is about going far here. T
Here’s an awesome Christmas “eco” DIY that you can try if you don’t want to chop up a real Christmas tree this year and save some trees, learn how to make a Christmas tree w/ hardback books!
For one, I know my relatives bought a small, fake plastic Christmas tree this year but this could be even a better eco-alternative to that.
Kudos for such a great idea!
I know, I know, you want a real Christmas tree. But I had a thought the other day, what if EVERYONE started not using real trees for Christmas? We’d save millions of trees ev
