Will Toyota lose money on its hydrogen fuel cell car?


Credit: Autoblog Green

It is widely accepted that Toyota lost money on every Prius is sold for a number of years. Something similar happened, & is probably continuing, with cars such as the Nissan Leaf & GM’s Volt.

Pat Cox of TransEuropean Networks has estimated that Toyota will lose €50,000 to €100,000 on its fuel cell vehicle, the Mirai. Thats $US60,000 to $US120,000 – more than the asking price of $US57,500.

OnePlus One phablet


Credit: Know Your Mobile

• 5.5 inch, 1080 x 1920 screen
• Snapdragon 801 quad core CPU at 2.5 GHz
• 3 GB RAM
• 64 GB flash storage
• 13 megapixel rear camera – Sony Exmor IMX214, f/2.0 aperture
• 5 megapixel front camera
• 4G
• 3100 mAh battery
• CyanogenMod version of Android
• enthusiastic reviews

And the price? $US349. If that’s more than you want to pay, there is a $299 version, which is identical, except for 16 GB flash storage & white rear cover, rather than black.

There are a couple of negatives:

• non-removeable battery
• no flash storage expansion

So, what’s the catch?

Buying one – apparently supply is limited – which may explain the, “This product requires an invite to buy”, policy.

A gearbox without gears!

Huge amounts of energy are wasted in gearboxes around the world. Losses occur in bearings, but more so between the teeth of the gears themselves. With this in view, the MAGDRIVE project has produced prototype gearboxes in which both conventional toothed gears & bearings are replaced with magnetic alternatives.

In space, cold & a near perfect vacuum create a unique set of problems for lubrication. Superconductor magnets make one prototype of MAGDRIVE a perfect match.

Expand your laptop storage – update

Some laptops have limited storage:
• older laptops
Chromebooks typically have only 8 or 16 GB of flash storage
Apple’s MacBook Air starts at 128 GB of flash storage – older models had even less

Most obvious solution would be to replace the existing storage, but this can be expensive. Plus, some laptops, particularly the ultra-compact, such as the MacBook Air, are difficult to disassemble or modify.

Much simpler is to plug in a flash drive. A 128 GB flash drive would increase the storage in many Chromebooks by 800%. This would be OK in a desktop machine, but in a laptop on a lap, or dropped into a backpack, a typical flash drive sticking out of a USB port is an accident waiting to happen.

Brando have a flush fitting microSD adapter which fits in the SD slot. It’s aimed at MacBooks, but will probably work with other devices with SD card slots, depending on just how deep the slot is. Only $10.

Brando also have an almost flush fitting microSD to USB adapter that will work with any laptop:

SanDisk Fit is a USB flash drive of similar physical size, & up to 64 GB capacity.

Modular phone

Choosing a phone is all about compromise. Big screen & battery have obvious advantages, but not when it comes to fitting into a tight pair of jeans. But what if you could tailor your phone for different applications? Big battery & screen for watching movies on a long plane flight; smaller, for sightseeing at your destination? Or tight jeans verses cargo pants?

Modular phone concepts have been around for some time. Phonebloks was first. When Motorola showed interest, it looked like it just might make it to market.

Apparently a development of Motorola’s interest, is Google’s Project Ara:
