Nuclear future on balance: world has not responded to Fukushima, Europe has

And of course Japan has too – as suffering such damage demands a general policy reevaluation. Apparently different political systems apply different forms of logic, a new report states. But we have just one investment market…

Natural nitrogen production: 1.5 per cent less global energy consumption

The introduction of nitrogen containing fertiliser in the 1860s has drastically improved crop yields. This not only increased the quantity of food that can be produced, but carbon uptake as well. But due to the high pressure and temperature requirements, … Continue reading →

Today’s paradox: coal is not worse for climate than natural gas

It´s basic chemistry: coal is mainly carbon, if you burn it you get lots of CO2. Natural gas is mostly methane, and that’s a different story. With methane just ’20 percent of the burned atoms’ are carbon, the rest is … Continue reading →

Making batteries greener and better with algae

Existing batteries are not known for their environmentally friendly components, since most contain heavily toxic chemicals. The much used lithium-ion batteries, best known for their use in cell phones and electric cars, for instance can contain pollutants that may decrease … Continue reading →

A new hope for hydrogen energy: nanoparticle driven and solar powered

Hydrogen would be an excellent clean energy source, were it not for the fact that it costs a tremendous amount of energy to produce and is thus quite expensive. Researchers have been looking for ways to cheaply and sustainably produce … Continue reading →

Engineering population growth: part 1, the problem

Ask engineers and they’ll say there is an engineering solution to any problem. With respect to climate change and geoengineering that’s hotly debated, with respect to overpopulation it’s a novelty. Today the UK-based Institution of Mechanical Engineers presented a report … Continue reading →
