The WaveFlyer – Electric Hydrofoil Jet-Ski

Wave Flyer Jet Ski__#2_        Wave Flyer Jet Ski__#1_

The WaveFlyer is the world’s first electric hydrofoil jet-ski, developed by an Australian company Electro.Aero, in collaboration with University of Western Australia. Essentially it is a personal craft that ‘flies’ serenely one foot above the water, powered by lithium batteries. It is similar to a jet-ski when stationary in the water but when it gets going it rises up using it’s actively stabilised hydrofoil propulsion system.

It can run for 30 minutes with 2 riders, whereas a conventional petrol jet-ski can run for 2 hours. The foils are most likely inverted T shapes rather than a V which are more efficient but can be prone to being more unstable, which may explain a slight instability in the video below. I should think like all these things it takes time to perfect it’s operation. The height above water is dynamically controlled using height sensors.

Major advantages of the new craft are: low pollution, quiet and smooth operation, and energy efficiency.

It could possibly be used in recreational lakes that prohibit fossil fuel powered crafts. This product has great potential and could really fly – excuse the pun !

Please see link below for YouTube video of the new WaveFlyer – enjoy !

Biodiversity from Old Oil Rigs

Biodiversity_fish_old oil rig_

There are some things left in the sea that actually add to the environment! Old oil rigs and other artificial installations are typically present for 20-30 years in the sea. Through this period the tubes, bars, concrete bricks and other materials turn into beneficial substrate for adhering plants and animals. This rich environment attracts fish and mammals. “In the North Sea an old oil rig will have the same function as a natural stone reef”, explains Jonas Teilmann, senior researcher from Aarhus University. He also says stone reefs are in short supply as stones have been removed and used for pier construction or spread due to heavy trawling.

The cost to decommission the world’s 7,500 oil and gas rigs, and 20,000 wind turbines at the end of their useful lives will be around £100bn, which has been mandated by international convention. Jonas and 30 other international researchers are making a case to review this, because biodiversity is increasing by leaving them in situ. These structures on the seabed are naturally protected from trawling too, which can turn a seabed into a uniform desert. They are calling politicians and officials to put a halt on mandatory decommissioning, and to carry out case by case environmental assessments as to which structures to leave.

It’s amazing how sometimes nature adapts man made objects over time whilst they return to their original default material state, and on the way help the environment !

Hope you have a good month

‘V’ Plane

Flying V Plane_#3_ Flying V Plane_#2_

The simple ‘V’ shape still has power to shock us as a plane design, but Delft University of Technology in the Netherlands has been developing the concept design recently, backed by Dutch Airline KLM. The design is partially based on a ‘V’ shaped Airbus patent. The blended wing-body integrates the passenger cabin, cargo hold, and fuel tanks in the wings. Two efficient turbofan engines are mounted towards the back on the same structure as the landing gear strut to minimise the number of heavy duty elements.

The aircraft’s spec matches the Airbus A350 in wingspan, seating, and cargo hold capacity. The key predicted difference is the 20% lower fuel consumption due to it’s improved aerodynamic shape, reduced weight, and decreased size of the ‘V’ shape design.

Flying V Plane_#1_

Why hasn’t this been done before? Because a wing design would need to accommodate a passenger cabin/cargo hold and yet be aerodynamic to create lift. Dr Roelof Vos believes he has the answer and explains that at high altitude a plane’s passenger cabin is under pressure and naturally tends towards a spheroidal shape. The V shaped plane has an ‘oval fuselage’ instead of circular one that accommodates this phenomenon. The design consists of tangentially connected circular arcs, with a trapezoidal substructure to take the compressive and tensional loads.

The V plane design is at the concept stage and undergoing wind tunnel testing and simulations. The initial results are very positive. The project team will present a flying scale model, and full scale interior section at KLM’s 100th anniversary celebration in October.

The question is will this ‘V’ shape plane become a commercial reality and really fly? I really hope so as the design is striking.

Hope you have a good month

Electric Super Car Race !

Aston Martin EV Super Car_#1_ Lotus EV Super Car_#1_

>>>>>  Aston Martin                                          >>>>>>  Lotus

When we think of fast electric cars we primarily think of Elon Musk’s Tesla cars, newest one being the Roadster – a direct threat to gasoline super cars. He now has stiff competition from main stream manufacturers but also from a most unlikely corner of the world – Croatia. A small company called Rimac is building one of the world’s most exciting cars an electric beast that can reach over 250mph !

What are the main players doing? In Italy Pininfarina a car manufacturer established before the second world war is building – a £1.5 million electric hyper car promoted as ‘a beautiful dream car’. In Britain, Lotus are developing a £1.7 million muscle car with an electric heart, Ariel is developing radical engineering on it’s HIPERCAR model, Aston Martin has just announced it’s first electric Rapide.

Pininfarina EV Super Car_#2_

>>>>>> Pininfarina

Development of electric engines is going a pace – a Tesla model S can hit 60mph in 2.4 secs the sacred realm of Ferraris and Lamborghinis ! Electric cars have an advantage in that continuous high torque can be delivered with improved traction through 4 wheels, without also accommodating gear changes and power bands. Software controls power delivery efficiently in real time for maximum performance.

The one question that begs to be asked, is how do you ever replace that amazing V12 engine sound that puts hairs on the back of your neck?

Hope you have a good month

Regenerative braking takes another step

Regenerative Braking_#1_

We are all quite familiar now I think with this technology, but there has been a incremental step in technology in it’s use in electric vehicles (EVs). When the battery is fully charged the regenerative braking is effectively turned off and reverts back to mechanical friction braking, where energy is lost through heat to the atmosphere.

If a power resistor is incorporated, regenerative braking could still be employed and the excess energy transferred to heat energy in a liquid. This in turn could heat the inside of a car, saving battery power. Another bonus is mechanical wear of braking system would be reduced along with service costs. The power resistor itself is low to zero maintenance because it has no moving parts. Power harvested should be around 7-10kW.

A downside to the power resistor is a ‘trade off’ between efficient cooling and pressure drop through the cooling channels from inlet to outlet. For the average car an extra pump shouldn’t be necessary but only for larger vehicles. This technology will slightly increase efficiency of EVs and help increase vehicle range – which is always welcome !

Hope you have a good month

Renewable Energy Storage Options

Wind Turbine Battery Storage_#1_

Hydro Electric Energy_#1_   Gravitricity_#1_

Renewable energy is growing but storage is one of it’s biggest problems. We need to be able to store turbine energy for windless days and solar energy for rainy days otherwise we can never discount dependency on fossil fuels.

Present technologies for storage include: (a)  pumped hydroelectricity schemes where water is pumped back up into a vast reservoir and stored as potential energy then released through turbine generators, but here there is little potential or inclination for new reservoirs, and installation costs are high.

(b) Lithium-ion or Lead-acid batteries are quick to respond to demand but are not seen as long term solutions – cost $154/kW year ($187 for lead-acid)

(c) Compressed air energy storage is another possibility where compressed air is stored underground but has disadvantages of heat generation on compression lowering efficiency to 50% – adiabatic compression raises it to 62% but this is still quite low – advantage high storage capacity – cost unknown

(d) Gravitricity utilises old disused coal or metal mine shafts by suspending weights of 500 to 3000 tonnes which are raised by motors to the top gaining potential energy, then lowered to release energy through generators – cost $141/kW year

(e) Flywheel energy storage whereupon mass flywheels are run up to speed, usually in a vacuum, via motors then energy is released when switched to generator mode that slows them down – cost $312/kW year

The consensus of opinion is to use a combination of all technologies to supply quick energy response along with longer term storage capabilities, whereupon the technologies are also linked and managed.

Option (d) I find personally interesting because it is efficient, has a relatively quick response time and utilises an old and redundant fossil fuel industry, bringing some employment back to potentially deprived area. In a word ‘regeneration’ !

Hope you have a good month

All the best
