We examine the lightweight hydrogen engine developed by an Israeli firm Aquarius Engines website A new, lightweight hydrogen engine concept from Israeli firm Aquarius Engines has been under development since 2014 and is close to maturity. Powered by hydrogen, the Aquarius Two Sided Free Piston Linear Engine (FPLE) is designed to generate electricity for plug-in series hybrids or range-extenders. The tiny engine consists of a mere 20 components, only one of which moves. Although originally designed to burn petrol, it could conceivably operate on a variety of fuels including the latest ‘dropin’ carbon-neutral, synthetic liquid fuels, and a hydrogen version of...

A new competitor is attacking the German energy market - with a sonorous name: Tesla. Hardly noticed by the public, the electric car pioneer introduced its first tariff for green electricity and is causing a stir in the industry. "We take Tesla very seriously and watch exactly what they are up to," says one of the major German electricity companies. Tesla not only sells electric cars, but has also been selling electricity storage systems and solar roofs for a number of years - and now also electricity. In this country, the first electricity tariff from Tesla boss Elon...

Crewed space missions call for colossal engineering projects. Case in point, researchers in China are investigating the possibility of assembling a spacecraft in orbit. The project is part of the nation's ambitions to expand space exploration, which encompasses crewed missions operating on long-term timescales. The proposal from the National Natural Science Foundation of China calls for an analysis of the mechanics of constructing an "ultra-large spacecraft spanning kilometers", according to an initial report from the South China Morning Post. In other words, China just told the world it's interested in building a spacecraft that is miles long....

Tesla (TSLA) has officially started Model Y deliveries in Europe. It was a long wait for customers, and interestingly the first deliveries were achieved through a change in strategy for Tesla. Tesla first unveiled the Model Y in March of 2020 and delivered the first units of the electric SUV in the US almost exactly a year later. Like any new introduction from Tesla, European buyers generally have to wait until the Fremont factory starts producing batches of European versions of the new cars and ships them to the old continent. However, the automaker announced a change in strategy...

New geothermal heating project planned at Nekala in Tampere, Finland, is targeting a depth of 7-8,000 meters for wells to derive geothermal heat for a local district heating system In a release, Finnish drilling services firm Robit Finland Oy has announced a cooperation with TEGS Finland Oy on technology developed for the drilling of deep geothermal wells. The planned cooperation will focus on improving the performance of drill bits intended for deep well drilling. The goal is significant cost savings. The geothermal heat produced by the deep well up to 7,000 to 8,000 meters to be drilled at Tampere, Finland will replace...
