Plastic in the post-oil age

Nowadays most plastic made of petroleum (better known as “oil”), but as oil is becoming increasingly scarce alternative sources for the production of plastic is needed. Scientists have succeeded in producing a biodegradable plastic from sugar and carbon dioxide. Continue reading Plastic in the post-oil age

Situational crime prevention

According to the crime opportunity theory the main cause of crime is the opportunity for prospective criminals to commit crime. Consequently crime can be reduced by eliminating opportunities for committing crimes, a strategy also known as situational prevention. In other words, by making it harder for people to commit crimes, more would-be offenders will abstain from illegal activities. Continue reading Situational crime prevention

Proton batteries

At The Guardian I found a very interesting article:

Look, no lithium! First rechargeable proton battery created.

According to the article, a team of researchers at the RMIT University in Melbourne have created a battery that instead of scarce lithium, uses carbon and hydrogen. The main benefit of this new type of battery, is that carbon and hydrogen are abundant and hence cheap materials.

With the increased popularity of electric vehicles, the demand for batteries increases and hence the demand for lithium and also its price. The limited abundance of lithium is a serious bottleneck for a more sustainable fleet of cars.

According to the scientists who made this proton battery it will take five to ten years, before it will be commercially available.

Space news

We want to share two news stories on ScienceDaily relevant for space colonization.

Roadmap to enhance radioresistance for space colonization.

Cosmic radiation is by far the most serious threat for space settlement, both orbital and surface-based ones. Without adequate protection from cosmic radiation, human space colonization will be impossible. Therefore research to protect humans against this radiation is of crucial importance.

Widespread water on the Moon

Water is indispensable for human life and hence the presence of water is of critical importance for any Moon-based settlement. Contrary to previous scientific understanding, there appears more water on the Moon. However, this water is primarily contained as hydroxy into lunar stones.
