Diesel trains have been used for the better part of a century on pretty much every railway of note because they're very cheap. Moves to add electric power to railway lines have taken place, but it's hugely expensive: Alstom puts the figure at €1.2 million per 100km, or $1.4 million per 62 miles. Of course, these days, most governments simply can't afford to bankroll large-scale electrification.Battery-electric trains, too, are out of the question, thanks to the sheer size, weight and cost of a battery that could run for 1,000 km on a charge. Hydrogen as a fuel, on the other hand, behaves pretty much like diesel, has a much higher energy density and it only takes 15 minutes to refuel a tank. And on trains, where weight and aerodynamics are less of an issue, you can add more tanks depending on your needs.From the outside, you certainly wouldn't have guessed that the Coradia iLint is a hydrogen train, looking just like its diesel-powered predecessor. But when it rolls up to approach … [Read more...] about The hydrogen train of the future is a lot like the train of today
PassProtect tells you if your password has been pwned
Have I Been Pwned? and you've gone and looked to see which of your accounts have shown up in a data breach, or signed up to get notified when they do.

120mm vs 140mm Fans for CPU Cooling?
I am planning a new Ryzen PC build with the 1800X CPU, I know this has been knocked off top spot by the 2700X but I got a good price on it (£170) so figured I might as well have the best of the last generation. Anyway as the 1800X has no stock cooler, and I would like the headroom to dabble at least with mild overclocking, I decided to get an aftermarket cooler for it. I went for the dual fan Cooler Master Hyper 212 LED Turbo one as here: https://www.amazon.com/gp/product/B071D3RQC3/ Upon looking around for reviews on it I noticed from the QA section on the Amazon product page above someone asked if the 2 x 120mm fans included could be swapped for 140mm ones and a couple of people confirmed they could as the cooler has mount points for either type. This got me thinking, could using 2x 140mm fans boost the cooling performance of this CPU cooler? I was thinking maybe with the 140mm fans having a larger surface area they might push more air over the heatsink or result in more air … [Read more...] about 120mm vs 140mm Fans for CPU Cooling?
Hosting Live Webinars That Build Your Brand and Drive Leads
How to Successfully Host a Lead Generating Webinar for Your Business Perhaps you’ve seen other brands hosting live webinars from time to time and figured they wouldn’t work for you. However, most brands discover that webinars are an extremely cost-effective and efficient method for generating leads and driving sales. Until you give it a try, you shouldn’t discount the role it could play in building your brand. The Appeal of Webinars The word “webinar” comes from the combination of “web” and “seminar.” While there are many different types of webinars, the goal is always to educate the viewer on a topic of importance and (ideally) nurture them through the buying process. Sometimes this means directly converting a sale, while other times it means qualifying a lead for a conversion further down the funnel. In some situations, a webinar is more about increasing brand awareness and visibility than anything else. Other times, … [Read more...] about Hosting Live Webinars That Build Your Brand and Drive Leads
