Electric vehicles

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.

Forget the obsession with driverless autonomous cars; energy independent vehicles are the megatrend. Electric land vehicles, boats, underwater craft and aircraft already exist that never plug in or refuel.

Small manned electric vehicles - e-bikes to car-like micro EVs - often sell in the largest numbers. Although they are usually lower in cost than regular cars, they will reach over $33 billion in 2026 according to IDTechEx analysis.

High Power Energy Harvesting (HPEH) is a term beginning to be used for creation of electricity where it is needed using ambient "free" energy. That zero-pollution, high-energy conversion typically captures light (photovoltaics), heat difference (thermoelectrics and heat pumps) and movement (electrodynamics).

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.

It seems obvious; energy harvesting is intermittent, so combine different types to make it continuous and therefore much more useful.

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.

The term 'energy harvesting' is most typically applied to powering small electronic devices using say sunshine, vibration or temperature.

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.
