Virtually all autonomous underwater vehicles are electric for practical reasons - the internal combustion engine ICE is not a realistic option. Not so on the surface, where the ICE is the favoured means of propulsion. However, even here, there is now a strong move to hybrid and pure-electric drivetrains for many powerful reasons, so it is timely to look at marine electric vehicles in general.

How is it that some analysts put pure-electric car sales at hundreds of thousands in 2012 whereas others report a mere 60-65,000? At analysts IDTechEx, we feel that a lack of rigor is largely to blame because there are cars homologated as such and car-like vehicles that are not homologated as cars.

IDTechEx has recently launched an online browser-based Market Intelligence Portal , bringing you in-depth market intelligence and independent analysis throughout the year.

The day is coming when electric vehicles (EVs) land, water and airborne are as much as 80% electronics and electrics if we include the power components.

The new report from IDTechEx titled Printed, Organic & Flexible Electronics: Forecasts, Players & Opportunities 2013-2023 finds that the total market for these technologies will grow from $16.04 billion in 2013 to $76.79 billion in 2023.

IDTechEx, the leading Research and Events company covering emerging technologies, has launched new subscription offerings across its range of topics.

Most electric vehicle sectors are profitable and growing. Toyota has nearly half of the $63 billion global market for electric vehicles land, water and air, according to an IDTechEx analysis in the new report, Hybrid and Pure Electric Vehicles for Land, Water and Air 2013-2023: Forecasts, Technologies, Players.

Maxwell Technologies, which has been the leader in supercapacitors worldwide, has been overstating its results by improperly recording certain sales through distributors.

Supercapacitors replace lithium-ion batteries. Lithium-ion batteries replace nickel metal hydride and lead acid batteries. There are side stories of course. Some supercapacitors replace electrolytic capacitors and others create new applications. However, in this article, we concentrate on replacing lithium-ion batteries.

IDTechEx is delighted to host the first INTRASME Electric Vehicle Opportunity Workshop 2013 which will now be a free session for a full day.

Electric aircraft are an idea whose time has come. Electrically propelled manned aircraft are selling profitably today in small numbers. They take the form of pure electric fixed wing microlights and motorised hang gliders. At the other extreme, airliners that have electric nosewheels have arrived making them electric vehicles when on the ground, hugely reducing noise and air pollution and making them independent of tugs. Yet that is only the beginning and the story is now rapidly unfolding across the whole industry.

Supercapacitors (ultracapacitors) are now center stage for designers of electronics and particularly power circuits. This is because they are improving faster than the batteries and electrolytic capacitors they increasingly replace. More subtly, they reduce the need for and danger from lithium-ion batteries. For example, when placed across a rechargeable battery, they protect it from fast charging and discharging and allow more of the energy in the battery to be utilised. Learn more ...

In this article, we look at other aspects of what will and will not happen with electric vehicles land, water and air in 2013, whether they are hybrid or pure electric.

The hybrid and pure electric vehicle business will continue to prosper in 2013, with profits and growth the norm in most sectors. Laws will proliferate that make electric vehicles the only way to go.

This article shares some of the research in the newly updated IDTechEx report, "Stretchable Electronics Comes to Market."

This article shares some of the research in the new IDTechEx report, "Supercapacitor/Ultracapacitor Strategies and Emerging Applications 2013-2025" (www.IDTechEx.com/SuperApps). We establish what is needed to create a billion dollar supercapacitor manufacturer: someone will. A prediction is provided of the coming shakeout in the industry including the number of manufacturers involved.

For the first time in this year's event in Washington DC on the 7th and 8th of November, a third event, focusing on supercapacitor technologies will be co-located, highlighting the advances, applications and adoption trends in this closely related field.

Graphene is one of the most exciting new materials currently being developed. It brings superlative performance to supercapacitors, batteries, touch screens, logic, sensors, displays, composites and much more thanks to its electrical, thermal and mechanical properties.

Lithium-ion is the winning type of rechargeable battery for the decade - there is almost a consensus. You can count about 150 manufacturers of these and IDTechEx has profiled nearly all of them.

Electric vehicles are not green just because they use electricity rather than fuel, but their green credentials critically depend on the materials used, the driving conditions and, most importantly, the carbon intensity of their electricity sources.
