The good stuff in wastewater - part 1
In a world of increasingly scarce resources, wastewater can provide us with heat (for our buildings) plus raw materials for fertiliser and for energy. It now makes sense to better use the good stuff in our waste water - that we are currently just wasting.
If only markets were long term, our sustainability problems would be fixed?
What if financial markets were not focused on short term gain? What if markets are actually long term focused, but that they believe that the pace of the sustainability transitions will be so slow that the business as usual scenario is still financially optimal.
Biological ageing - this is the way
Biological or cellular ageing is driven by a number of mechanisms. As our understanding of those mechanisms has improved so the promise of stopping or even reversing ageing comes closer to reality.
Battery storage - the next transition boom industry?
Battery storage has an increasingly important role to play as we build out an electricity grid dominated by renewables. But, current revenues from filling the generation gaps left by variable renewables are actually small, with the main income stream being from the smaller grid stability market.
All that glitters is not gold
Gold Mining: as well as being the largest global artisanal mining activity, also faces a number of sustainability challenges. One is where it comes from, and another is how it's processed.
Innovation in feeding cattle
Innovation in livestock feeding can minimise their impact on the environment, improve their health, and help with logistics.
Is gas flaring a solvable problem?
Gas flaring is part of the wider methane emissions challenge. It gets a lot of attention, in part because its highly visible. How easy is it to fix ? Part solutions seem easy, and financially viable, full solutions look tough.
The landscape of biological ageing
Whilst we are living longer on average, our desire to 'cheat death' remains. And it has spurned a big, and growing industry.
The cyber threat to our key infrastructure
Smart grids are making our electricity systems more responsive and reliable, better able to handle the addition of more renewable generation, and they are contributing to reducing costs. But they also bring cyber risks.
Taking TV for a 500 mile drive?
This works out at a daily working return commute of only 2 miles per day - suggesting the impact of watching TV for a year is small. However, taken globally, the number of individuals doing that same activity is large and that soon adds up to something meaningful.
Reducing electricity demand and still staying cool
For many in the world, staying cool in the heat of summer is as important as staying warm in the winter is to those of us who live in the the northern latitudes. And yet it often gets a lot less attention in the electricity security and supply debate.
Will half the world starve without fossil fuels?
Not producing gas means we can't produce fertilisers, which in turn means we can't produce enough food to feed half the World. But is that true?
