Since the previous epi is on biogas, I thought I'd show what a biodigester looks like and How it turn waste food into usable gas. Yeap, without starter kit, you might need to wait up to 8 months before the gas is usable. Anyway, in our current time, bacteria and other stuffs can be added to speed up the process.

6 mins intro.

Building an Inexpensive Hydroponics/Aeroponics System

Nowadays, all these are available in ready kits. But....you'd have to figure the nutrients part on your own, such as NPK, which is usable using the Local Fish Shop (LFS) bottled nutrients such as Seachem Nitrogen (e.g.), or get the garden ready mixed ones. Dilute properly before you use it.

National Geographic
Transforming Lives through the Power of Clean Water

It will cost you SGD$2.26 per pack if you buying in 12 packet. And $0.57 if you buying in 240 pack bulk form. Original is in USD. I convert to SGD for easier understanding. (12 pk = USD$19.99, 240pk=USD$99.99)

Home of the Future S1 E2

This series talks about using of Solar energy. Hmm...the downside, I don't really like the idea of using Lithium Ion battery as the backup power source, that gives you a potential bomb.

Home of the Future S1 E3

Home of the future needs a brain, so this looks at the creation of the brain itself. And there is no lack of sound amplifier, game machines, cameras etc.

Home of the Future S1 E4

In all houses, you will need security. Security on your dumb network as well. You be looking at privacy. Of course the law refers to US law but are targeting Tech Companies who are collecting consumer data without consent.
