Two hundred years ago it seemed that steel was unstoppably at the heart of transport, from rail to shipbuilding. It brought with it massive health problems, from mining the ore and coal to making the ships and railroads.

In this article we introduce some guidelines useful in formulating your strategy. In other articles we have given the latest on tools that are useful such as the profitability V curve and the experience curve.

Hikers, soldiers and school children all know the burden of a heavy backpack. But now, researchers have developed a prototype that not only makes loads feel about 20% lighter, but also harvests energy from human movements to power small electronics.

The 4m€ BOOST project, funded and led by the European Commission, aims to design and deliver solutions to build a full-scale 0,25MWp Floating Solar Photovoltaic in Europe's sunniest area, the Canary Islands.

Transparent solar cells can be used in windows. But until now, they have either not been particularly effective or very transparent. A new project will change that. With a revolutionary concept, the EU project CITYSOLAR will make energy-producing, transparent windows, mainstream.

Portuguese authorities have joined the Swedish Energy Agency, EIT InnoEnergy and private investors to support CorPower's flagship HiWave-5 demonstration project in northern Portugal.

A valuable tool in predicting risk and enduring profitability of businesses is the profitability V curve.

Thursday 18 February 2021 - Emerging 3rd and 4th generation emissive materials for OLED displays; A technological transition that increases the efficiency of organic photovoltaics; Functional inks for lighting; and Low temperature component attachment materials.

Xiaomi has introduced a brand new form of charging - Mi Air Charge Technology. Revolutionizing the current wireless charging methods, Mi Air Charge Technology enables users to remotely charge electronic devices without any cables or wireless charging stands.

In 1936, Theodore Paul Wright, at Curtiss-Wright in the United States, found that every time total aircraft production doubled, the required labour time for a new aircraft fell by 20%. This has become known as "Wright's law".

Wednesday 3 February 2021 - 5G communications has come to a phone near you and 6G communications received strong investment in 2020 as we move to its standards, specification and substantial rollout in 2030. However, this time will be different because the objective is far more heroic.

In 2017, after four years of setbacks and crashes, Alphabet shut its project flying solar-powered fixed-wing drones in the upper atmosphere to beam the internet to those cut-off. They have now ended their upper-atmosphere balloon version as well.

Eco Wave Power announces the winning of the Smart Port Challenge Competition. The goal of the challenge was to find disruptive solutions that will facilitate transit at Morocco's ports and improve port performance.

Black Dog Biogas has completed commissioning of a private wire to supply renewable electricity to Vestas' neighbouring wind blade manufacturing facility.

Namene Solar announced their latest carbon offsetting project in Namibia, certified by Gold Standard. It's the first project in Namibia to receive the certification. It will see climate finance subsidise the sale of the company's award-winning solar lights to rural homes and informal settlements across the country.

DeepGreen Metals, which is exploring for deep-ocean polymetallic nodules as a lower impact and more cost-effective alternative to terrestrial mining, announced an upward revision to the nodule resource reported within the NORI-D exploration contract area held by its subsidiary, Nauru Ocean Resources Inc. The nodule resource is now estimated as 4 megatons measured, 341Mt indicated and 11Mt inferred mineral resources.

Strategic Elements Ltd has achieved another significant milestone with its self-charging battery technology successfully generating an output of over 4V from moisture in the air over a testing period of approx. 5 hours. This was achieved through development of a prototype battery pack containing multiple connected battery ink cells.

A material that can be used in technologies such as solar power has been found to self-heal, a new study shows. The findings raise the prospect that it may be possible to engineer high-performance self-healing materials which could reduce costs and improve scalability, researchers say.

Renewable energy sources, such as wind and solar power, could help decrease the world's reliance on fossil fuels. But first, power companies need a safe, cost-effective way to store the energy for later use.

Researchers have developed flexible thermoelectric devices with high power generation performance by maximizing flexibility and heat transfer efficiency. The researchers also presented a mass-production plan through an automated process including a printing process.
