There are 3 websites I recommend visiting:
This site rankes brands of all kinds of products, including electronics.
Rankings are based on all information that can be found on a company's website and in their annual reports. Rankabrand assesses brands on
their environmental performances, climate change efforts and labour conditions.
Make sure your laptop is failing physically before deciding to buy new. It might just be that it's too old and worn to run Windows, but installing Linux might work. The easiest version to use is Linux Mint. See here for a guide: http://moderngreenlife.com/save-an-old-pc-from-landfill-with-linux-mint-xfce/
If you really have to buy one new, then spend a bit ...
...would it be technically possible to produce everlasting (or at least) longer lasting toothbrushes?
Yes. You can use a wire brush - since it's harder than the teeth it will be used on, it will not wear out.
The teeth, however, will wear out.
The root problem is that the purpose of the toothbrush is to remove material that is softer than your teeth, ...
I think you're right that building your own is likely to be necessary (we're in the same position). What I've discovered in Australia is broadly applicable in the global north, so:
An earthship can't be sustainable, and is not designed to be sustainable - they are about being self-contained within a very narrow definition of the term. They rely on free ...
I suggest that you question some of your assumptions.
Difficulties of off-grid.
Off-grid is HARD, and generally isn't worth it unless you are a long ways from the power lines. If you are looking at one acre, you probably aren't that far away.
Let's look at what goes into off grid:
Grid connected solar means you size your PV to provide about ...
I'm a retired dentist, new to this site. All the answers are good. I'm not qualified from an engineering standpoint to comment on this subject but I do have some useful input I think.
Probably the most important thing to remember when brushing is that what you're removing is the soft plaque and it will be easily removed with a soft bristle toothbrush. If ...
If by everlasting you mean buy once, use it throughout you life and have it buried with you when you die, the answer is no. Everything wears out and the softer something is the more likely it is to wear away more quickly, particularly when it rubs against something that is harder.
The other thing to consider is the affect toothbrushes will have on people's ...
From what I've been reading is not possible (at least yet) to produce an everlasting toothbrush due to the wearing of the bristles. But there are a few alternatives available that are more sustainable than conventional plastic toothbrushes.
There are toothbrushes made of biodegradable materials (they promote themselves saying that you can compost it) where ...
Always try to buy hardware, that is easy to repair and upgrade. This will save you from throwing it away to buy another one, when it breaks, starts to overheat due to dust in the fan or needs more memory, new hard drive etc. IFixit has a ranking of "repairability", that is really useful.
There are plenty of sites selling reconditioned laptops or second hand laptops. Some companies upgrade regularly and this releases perfectly serviceable computers to the public. These surely have better credentials for sustainability than a new eco laptop.
I won't link to sites to avoid providing advertising but I must have purchased three laptops in this ...
I thought a new development would be worth mentioning: CrowdSupply hosts a successful crowd-funding campaign for the EOMA68 line of computing devices. EOMA68 is a standard, and the computing devices have the benefit of using easily-replaceable parts to fix or upgrade them, 3D-printable casings, and components that can move from one casing to another (for ...
The easiest design I've ever seen was made from materials obtained from a "Dollar" store. It was a cone shaped design made from:
A windshield reflector
A cooling rack
A black enamel pot.
The windshield reflector was folded into a cone shape with the indention to fit around the rear view mirror forming the "tip" of the cone. Velcro was applied to the ...
You might want to look at refillable pens, where you do not have to throw away the whole pen if it's finished, but can just replace the inside. You can buy them in most office stores and are not very expensive (often less than 1 dollar/euro/pound for a refill).
A lot of pens are refillable so it's worth looking if you may already have one laying around!
It may cost a lot of green, but Macs and Apple are particularly green. Apple has many protocols and material regulations they use in their products. That's one of the reasons they cost so much, is the good materials they source.
I will agree with the labor problem, but they have good materials. See the model you might want, they have PDFs discussing the ...
