Optima Electric Boats will revolutionise leisure boating with an innovative new range of high quality, electric cruising boats which aim to significantly reduce pollution, emission of greenhouse gasses and noise, thereby protecting the planet and the marine environment.
The Optima electric boat has an ultra-efficient low-resistance hull form providing the opportunity for all-day cruising in comfort and silence under battery power.
They are capable of extended ranges of over 100 miles and will be self-sufficient for weeks away from shore-power using a combination of integrated solar PV charging, traditional and renewable energy sourced fuel cells.
The first Optima presented measures 36 feet (11 meters). It can be fitted out with two double cabins, has extensive gallery and can seat 8 people around the cockpit table. The optional roof provides protection against sun or rain.
An ergonomic helm station provides comfortable seating for two. Twin electric drives provide exceptional manoeuvrability and easy joy-stick controlled docking.
The three hulls aft ensure perfect stability both underway and at anchor - the unique platform provides the efficiency and stability of a multi-hull but within the beam of a mono-hull. This results in levels of efficiency, comfort and sea-keeping not previously seen in mono-hull designs, whilst maintaining the practicalities & berthing possibilities of a mono-hull.
Far more significant than just electrifying the drive-train, the exceptionally energy efficient new hull-form dramatically reduces energy consumption allowing ranges of over 100 miles under battery power, with exceptional comfort, making the journey much more enjoyable than it currently is in a fast planning hull.
The boats’ twin electric drives will reduce energy consumption compared to conventional motors, ensuring a full day’s cruising at eight knots and a top speed of 14 knots.
Hydrogen Car
Key Facts
The Toyota Mirai is a mid size four door saloon launched in Europe in September 2015. ‘Mirai’ translates from Japanese to English as ‘the future.’
This vehicle uses a hydrogen fuel cell to power the electric motor that drives the vehicle. Toyota began fuel cell development in Japan in the early 1990s.
A Mirai will do roughly as many miles on a kilo of compressed hydrogen as a modern petrol-fuelled hybrid will do on a gallon of unleaded.
Between September 2015 and February 2016, one Mirai was driven 100,000 km (62,000 miles) in 107 days on different roads in Hamburg, using just over one tonne of hydrogen.
Specifications
Official range ~ 300miles, real world range ~ 250miles
Fuel capacity: 5kg of Hydrogen
Max Motor Output: 113 kW ( 152hp)
Max Motor Torque: 335 N.m (247 lb.ft)
Filling time: around 5 minutes
Number of stations in the UK: 11 open to the public, most of them use onsite electrolysers to create the hydrogen
Cost of Hydrogen: Between £12-16 per kg (depending on vendor)
Emissions: Consumes compressed hydrogen gas in tank and oxygen in air to emit nothing but water
Speed: The system accelerates Mirai from 0 to 97 km/h (0 to 60 mph) in 9.0 seconds
‘Spirit of Innovation’ all-electric aircraft
Key facts
Rolls-Royce is leading a highly specialised challenge to build the world’s fastest all-electric aircraft. The ACCEL programme, short for ‘Accelerating the Electrification of Flight is 50% funded by the UK Government through the ATI and Rolls Royce are working with partners YASA, the electric motor and controller manufacturer, and aviation start-up Electroflight.
They have completed the taxiing of our ‘Spirit of Innovation’ aircraft, and the plane has powered along a runway propelled by its powerful 500hp [400kw] electric powertrain and the latest energy storage technology developed to set world speed records and enable a new generation of urban air mobility concepts.
The first flight is planned for the coming weeks and when at full power the combination of electrical powertrain and advanced battery system will power the aircraft to more than 300mph, setting a new world speed record for electric flight.
The aircraft will have the most energy-dense battery pack ever assembled for an aircraft, providing enough power to fly 200 miles (London to Paris) on a single charge. Its 6,000 cells are packaged for maximum lightness and thermal protection. An advanced cooling system can withstand the extreme temperatures and high-current demands during flight.
The world record attempt is planned for this summer and the characteristics that ‘air-taxis’ require from batteries are very similar to what is being developed for the ‘Spirit of Innovation’ so that it can reach record-breaking speeds.
Rolls-Royce are bringing a portfolio of motors, power electronics and batteries into the general aerospace, urban air mobility and small commuter aircraft sectors as part of their electrification strategy.
Bike - Harley Electric Livewire
Specifications
Official range: 146 miles of city range/95-98 miles of combined stop-and-go and highway range
Capacity: 15.5kWh total (13.6kWh min usable)
Max Motor Output: 105 horsepower (78 kW)
RPM Max 15000
Max Motor Torque: 86 ft-lb (116 Nm)
A Level 1 charger can give 13 miles of range for each hour of charging; this means a full charge can be expected overnight.
A DC Fast Charger can provide 192 miles for each hour of charging. Realistically it means 0 to 80% charge in 40 minutes and a full charge in 60 minutes.
Speed: The LiveWire can accelerate from 0-60 mph in 3.0 seconds, and 60-80 mph in 1.9 seconds.
Unlike an internal combustion engine (ICE), the H-D Revelation can produce 100 percent of its rated torque the instant the throttle is twisted, and 100 percent of that torque is always available
Electric Bus - Yutong E10
Key Facts
This vehicle is a fully zero emission single deck bus with capacity for up to 34 seated + 36 standing passengers + total of 70 passengers.
Motor: Single electric drive motor. (Max power 350KW. Max torque 3200Nm) The motor is water cooled with it's own radiator.
Batteries: Twelve LFP (Lithium Iron Phosphate) water cooled battery packs, total of 422kwh capacity. The battery management system is unique to Yutong and constantly monitors temperature, voltage, current and capacity in the batteries.Modular design of battery packs means they can easily be changed in the future if better battery technology come available mid-way through the vehicle life.
Rapid DC chargers up to 150kWh’s mean a full charge is possible in under three hours. the vehicle can complete over 250kms (155 miles) on a single DC charge – it can handle most city bus operations on a single daily charge.
Heating/Cooling: Roof mounted cooling and heating air conditioning- the A/C system is fitted primarily to provide heat although cool air function is available. Four 2.5Kw floor level back up radiators are provided and are usually set to come on when temperature falls below zero.
The driver and passenger experience is second to none, with separate air-conditioning for the driver and the passenger saloon, no engine vibration or noise, LED lighting enhancing the saloon and separate USB charging points.
Currently E10’s are operating in Newcastle, Leeds and Newport as well as an executive version in service with Scottish Power. London trials have shown the E10 to have an excellent turning radius and manoeuvrability.
The vehicles have performed exceptionally well, including during recent periods of heavy snow and did not show any substantial degradation in battery capability whilst operating through snow and ice and in temperatures as low as -4º.
The vehicle is likely to cover approximately 50,000kms (31,068 miles) per year.
