Add Commentyes, but do they still decompose in 180 days in landfills, where there is no sun or oxygen to accelerate or start the decomposition process?
Reply | Report Abuse | Link to thisI remembered my mother making very handy totes from discarded dresses of my sisters and her sari. They were so trendy, compact and eco-friendly. my observation may be shared by many around. Incidentally, the save earth or responsible utilisation of resources was still not the in thing then.

Reply | Report Abuse | Link to thisWhen science and technology magazines present these fantastic "electric bikes" I wish they would also present real world information about things like "Can It Go Uphill?". I, for example, bike to work often, but my commute involves climbing a 500ft grade on the way back. I would love an electric bike, but everything I've read says those babies can't do hills at all. Until then I'll stick to my $250 -- order of magnitude cheaper -- bio-powered bike.

The salt water serves as the electrolyte for two dissimilar metal electrodes in the water resevoir of the clock. The power comes not from salt, but a chemical reaction that is dissolving one of the electrodes. Somebody should be embarrassed!

A better idea would be to just have two containers with water flowing from a container at top to another at bottom and the kinetic energy used to generate power. The water could be transferred back to top container every week

Reply | Report Abuse | Link to this??? didn't SciAm recently have an article about how nanoparticles when ingested can harm you similar to the way asbestos does?
There are no nano particles in the ceramic nano glaze that could be compared to asbestos because our glaze is made of inorganic, inert and non reactive minerals. Our ceramic glaze can also withstand thermal temperatures of 2500F. The glaze is made of natural minerals from the earth's crust and our ceramic glaze has been proven to be 100% healthy by three independent worldwide scientific testing laboratories. There is no other cookware manufacturer that has made that claim besides Ceramcor which makes the Xtrema cookware.

When large efforts are made to improve the efficiency with which resources are used, the resulting savings are easily and completely wiped out by the added resource needs that arise as a consequence of modest increases in population.
A) When resources are used more efficiently, the consequence often is that the "saved" resources are not put aside for the use of future generations, but instead are used immediately to encourage and support larger populations.
B) Humans have an enormous compulsion to find an immediate use for all available resources.
Tenth Law
The benefits of large efforts to preserve the environment are easily canceled by the added demands on the environment that result from small increases in human population.

After all, does your Nano Glaze contain nanoparticles (whatever their origin might be) or not? If not, why do you call it Nano? Thank you!
