Future Driving – Hydrogen or Batteries?

[] – It’s too early to write off hydrogen vehicles

Our comment: we are uncomfortable with these huge batteries too. Our educated guess: batteries for light-weight 2-3 wheel vehicles for the shorter distances like commuting/local traffic and hydrogen for larger vehicles like multi-person on-demand transporters, trucks, trains, ships, planes.

Driving Patterns

A 2016 British study can give us an idea of how the car is being used. Results: most trips are rather short, with 95% less than 25 miles and 66% less than 5 miles. However, if you add all journeys below and above 25 miles, the results is about 50-50. The number of all trips, short or long, has declined over the past 12 years.

Combining the data, perhaps a compromise solution for future transport architecture could be: private ownership of a cheap, light-weight vehicle for 1-2 persons, like the Carver in the previous post, for the short distances, that still comprise 95% of all trips and do the rest with public transport, like bus and train and later autonomous driving vehicles. A range of 100 km would suffice for that purpose and allow for relative light batteries.

Carver Goes Into Production

The Carver presented at Top Gear in 2011 was the gasoline version, of which at least 500 were produced and sold for 42,000 euro. In 2015 there were Chinese plans to produce the vehicle, didn’t happen. Now an e-version is out, produced in the country of origin, Holland.

Price: €7,990,-
Range: 90 km
Battery: 5.3 kWh
Weight: 330 kg
Top-speed: 185 kmh, formula-1 feeling comes included
(Just kidding, that was the original Carver One like the one in the Top Gear video, the e-version does merely 45 kmh in order to keep it in the scooter range; in some Asian countries 60 kmh will be possible, according to local legislation. There is no inherent design limitation to a speed of just 45 kmh, it is just that the producers want to market this vehicle as a scooter first, with lower legal admission hurdles)
Storage: 75 liter

Average Dutch commuting distance: 34 km. Dutch holidays: 6 weeks, which leaves 46 working weeks = 230 working days or 7,820 km. Efficiency: 90 km/5.3 kWh = 17 km/kWh. Yearly commuting electricity consumption: 7820/17 = 460 kWh. In grey, rainy Holland the relationship between a solar panel peak-Watt and yearly yield = 0.85. A standard 280 Watt panel produces per year 280 x 0.85 = 238 kWh. In other words, in order to produce the electricity to keep a Carver going for commuting, you merely need TWO solar panels extra on your roof!

It is high time that we draw conclusions from the simple fact that the average occupation rate of a car is merely 1.25. These standard 5 seats are massive overkill and so are the 1200 kg or so that the average 5-seat car weighs (in Europe, do not get us started about the US).

Vehicles like these could be a serious alternative to autonomous vehicles. The Carver could be autonomous too. Perhaps the passenger seat should be dropped for more battery capacity.

Flyland – Dutch Airport at Sea?

With the offshore energy Bonanza in full swing and city state Holland becoming full, the potent Dutch maritime industry is developing an appetite to develop an extension of Amsterdam “Schiphol” airport at sea. Now that Britain is retreating from the European world, possibilities arise for Amsterdam to take over from Hearthrow Airport as the greatest European intercontinental hub. But a large expansion of the existing airport is no longer possible, for space and noise reasons. But at sea there is sufficient space, the horizon is the limit.

Sailing the Oceans with Renault

Youtube text:

Car manufacturer, Groupe Renault, is partnering with French designer and operator of cargo sailing ships, NEOLINE, to reduce the carbon footprint of the Group’s supply chain.

NEOLINE has designed a 136-meter ro-ro with 4,200 square meters of sail area it says has the potential to reduce CO2 emissions by up to 90 percent through the use of wind power primarily, combined with a cost-cutting speed and optimized energy mix.

The vessels will be commissioned by 2020-2021 on a pilot route joining Saint-Nazaire in France, the U.S. Eastern seaboard and Saint-Pierre and Miquelon (off the coast of Newfoundland in Canada).

LightYear Solar One Goes in Production

Solar Team Eindhoven in the Netherlands made good on its promise to bring the world’s first solar car into production. Born from the Australian Solar Challenge, a race for solar cars through the Australian desert, students/engineers from the Technical University of Eindhoven helped maturing the technology to the production stage, realized earlier this month in Helmond, the Netherlands. Initial small volume price tag: 119,000 euro.

New Impetus Street Car Ground Level Power Supply

Bordeaux street cars, still with old-fashioned catenary

The French city of Bordeaux was the first to replace the catenary of its street cars and replaced it with a third ground rail. After 2011 the technology has been adopted in Reims, Angers (both France) and Dubai. The system is safe for humans and animals. Wikipedia:

APS uses a third rail placed between the running rails, divided electrically into ten-metre rail segments with three-metre neutral sections between. Each tram has two power collection shoes, next to which are antennas that send radio signals to energise the power rail segments as the tram passes over them. At any one time, two consecutive segments under the tram will be live.

Below, how Bordeaux ground-level power supply looks like:

Arlanda Test Results

The idea: mount a metal conductor strip/rail to the road and voila, you have an e-road, a sort of inverted trolley-bus system for cars and trucks. If a country like Sweden would install these rails in the main routes only, ensuring that no home would be further away from a road with such a rail, it would reduce the required size of the battery of e-vehicles enormously. Think 50 kg instead of 400 kg, because the car would charge the battery during driving.

A test route was equipped with a conducting rail earlier this year and the test results are in. And they are encouraging. 200 kW can be delivered, think a truck. The system works good under snow and ice conditions. No need for heating the rail.

Back-of-an-envelope calculation of the cost of an e-road system: The producer Elways claims that the cost per kilometer for 2 lanes is less than 1 million dollar. Go to Google Maps to verify that from Malmö in the South to Gällivare in the North it is 1740 km over road. Two parallel North-South roads exist, that’s 3500 km at a varying distance of 50-150 km. Add some East-West legs to connect these two roads and you arrive at perhaps 5,000 km or less than 5 billion $ to electrify your roads. Sweden has 10 million citizens, so that would be 500 $/capita. That’s very affordable. Note that autonomous driving will relieve the population of the need of owning a car, reducing the per mile cost with a factor of 4-10 according to this study.

If you realize that the average occupation rate of your standard sedan is ca. 1.25 persons, meaning that a car mindlessly mainly moves 3.75 empty seats around… if you additionally realize that in a carbon-starved world, not because we run out of carbon but rather that we running into limits of the amount of carbon the atmosphere can handle, we cannot continue with our old ways… if you also realize that a car is mainly used for single person commuting (in Holland on average 34 km/day), shopping and business travel and not for happy families of 5 travelling to the seaside with dad-knows-best behind the steering wheel and mum distributing the sandwiches… these three realizations should really cause car designers to rethink traditional personal transportation assumptions.

Enter the Swiss-made Microlino:

Battery: 8 kWh or 14.4 kWh
Acceleration (0-50 km/h): 5 seconds
Range: 120 km or 215 km (with 14.4 kWh battery)
Maximum speed: 90 km/h
Price: 12,000 euros
Market-ready: 2019

Note: this could be the solution for those happy few who still will own a car. For the lesser Gods, the self-driving shared van could be the future.

Callisto & Prometheus – ESA Space Transport Reusability

14 December 2017 – An ultra-low cost reusable rocket engine, Prometheus, using liquid oxygen–methane propellants, is set to power Europe’s future launchers. Today, ESA and ArianeGroup signed a contract to develop a full-scale demonstrator to be ground tested in November 2020. Prometheus demonstrates the systematic application of an extreme design-to-cost approach, new propellant and innovative manufacturing technologies. It lowers costs to a tenth of those for Ariane 5’s Vulcain 2 engine.
