A new way of modelling wind turbines, could lead to an 1% increase in the amount of wind power generated – for free

Usually in order to increase the power generation from anything, it needs new hardware – if you wanted to increase the amount of power from a set of solar panels on your roof there is little you can do, without replacing them (this of course pre-supposes that the panels are in a good location, and are not in the shadow of a tree).

That is why this is incredibly exciting. The idea of being able to roll our new rules about how wind turbines work, and instantly make 1% more energy is incredible.

It is true that, currently, wind only accounts for about 6.5% of electricity generation. Conversely, it accounts for 24% of renewable generation – which is quite likely to be a percentage that grows as we move towards 100% renewable electricity generation.

So, with this change it will only account for 6.565% what difference is that?

Well, last year the world generated 28500 terawatt hours, which means that 0.065% increase is 18.5 terawatt hours extra created through 100% green sources.

Now, between 2020 and 2022, the average carbon emissions per kwh was around 370g. As such, were all of this energy created in the USA (it is not the most expensive or the least, so we are going to use it as representative – even though this power would be generated around the world) this much extra green energy would save 0.370 time 18.5 time 10 to the power of 9 (there are 1,000,000,000 kwh in 1 terawatt hour) which means that this little modeling trick would have saved roughly 7 million tonnes of carbon emissions. Now while this is relatively small in global terms (with 50 gigatonnes of emissions in 2020) it is still not insignificant – indeed, it is equivalent to the total emissions of Botswana, or indeed Latvia in 2021. That strikes me as an easy move, perhaps looking at this in a different way, perhaps more importantly, for wind farm companies, this energy is worth roughly £340 million ($450 million)

Lightyear one

The lightyear one is an incredible car. It is a highly efficient electric car, and gets over 440 miles from a battery smaller than the one in the long range tesla 3 which only has a range of 353.

This is partly because it is an incredibly efficient car – each wheel has its own, in wheel, motor. However, even more exciting, the car is covered in high efficiency solar panels – it has 5 square meters of solar panels, which is allow between 25 and 45 miles on solar power alone.

MIT scientists have developed a process which can desalinate water using the sun

Desalination is an extremely power hungry process. Either of substantial amount of pressure is required or evaporation of the water.

However recent process by MIT looks to hugely improve the efficiency of such a system. Using a series of evaporators and condensing sections they have been able to reach an efficiency of 385% ( Due to the reusing of this ambient heat allowing an efficiency well in excess of 100%)
