Today's emerging technologies are varied, vast - and moving at the blink of an eye. Here are the top 10 key trends we'll see at the show that are changing the way the world lives, works and plays.

The graphene industry is at a critical juncture for many small to medium sized companies: it is time for them to generate revenues and pre-empt any pending cash flow issues. These companies cannot often afford to take the long view, which many research groups and government are rightly taking.

Graphene finds users in California (Our most exciting graphene conference so far).

High power energy harvesting (HPEH) is the clean part of off-grid renewable energy and its main potential lies at kilowatts to megawatts. Few things are genuinely new in this world but newly important aspects of energy harvesting really matter.

Thought leaders IDTechEx were among the first to identify three new megatrends in the world of technology: Structural Electronics (SE); 3D Printed Electronics (3DPE); Energy Independent Electric Vehicles (EIVs).

Whilst existing battery technologies such as lead acid and lithium-ion batteries will dominate the battery market in the following 10 years, advanced and post lithium-ion batteries given the right conditions can potentially take a considerable dent of about 10% of whole battery market by 2026.

The most dramatic new advances and visions have no name initially. So it is with electric vehicles that need no external charging or refuelling - no, not even wireless charging.

A trillion dollar opportunity to 2035, electric buses are being completely reinvented because they are the electric vehicle sector already attracting billion dollar orders and they can prevent millions of deaths and injuries from air pollution.

Plenty of kilowatts from no fuel. This dream ticket is a reality today from the rapid adoption of high power energy harvesting. Energy harvesting converts ambient energy into electricity where it is needed, off-grid.

Analysts IDTechEx almost completely rewrote their report Power Electronics for Electric Vehicles 2015-2025 this year and frequent updates take place, such is the pace of change.

Buses are now a crucible of change, often adopting new technology before cars.

Totally different. Everything that constitutes a hybrid or pure electric vehicle will change beyond recognition, advises analyst group IDTechEx.

Each year IDTechEx Research releases its up-to-date market report on graphene and related materials: Graphene and 2D Materials: Markets, Technologies and Opportunities 2015-2025.

A new design strategy has emerged for making batteries flexible.

The power electronics business as applied to electric vehicles is becoming so huge that very divergent approaches become viable.

IDTechEx interviews in Japan have established that supercapacitors across lithium-ion batteries in cars can increase range by 10% by permitting deep discharge, provided suitable batteries are used that can tolerate such a regime.

This article shares some of the findings of the new IDTechEx Research report, Fuel Cell Electric Vehicles 2015-2030: Land, Water, Air and some of what will be discussed in the forthcoming IDTechEx webinar on 9th June.

IDTechEx's Electric Vehicles: Everything is Changing, conference was successfully held during the 28th and 29th of April 2015 in Berlin.

What ducks and batteries have in common? The answer is Tesla's new home energy storage system. I will explain why.

There is divided opinion on future of traction fuel cells in electric vehicles, though few argue any more that they will power the majority of electric vehicles.
